tioning the center of gravity of the luggage as
low as possible, so pack heavy items in the
bottom of your panniers.
Take care that your luggage is safely stored on
the racks. Bags must be tightly fastened to the
racks so they can not move. Make sure that
loose parts like straps or belts can not touch
the wheels, the derailleur, or the suspension.
The rear rack is designed for standard tricycle
panniers. On Scorpion tricycles with 26 inch
rear wheels, only side bags can be used.
Take care that your luggage does not cover
the lighting system and the reflectors of your
tricycle and that they stay fully functional.

General safety instructions
Your tricycle has been delivered to your specialist dealer only partly assembled.
Your dealer has carefully finished the assembly, perhaps altered the specification of your
tricycle to meet your special requirements
and performed a test ride. Please make sure
that this pre-delivery service is recorded in
the Warranty Pass at the end of this manual.
All screws must be checked and tightened,
especially on the handlebar, stem, knuckles,
swing arm pivot and wheels. Please follow the
tightening torque settings listed in the table on
page 88.
Derailleurs and brakes must be checked and
adjusted. Please follow the instructions in the
manuals of the parts manufacturers that come
with this manual.
Bolts and nuts
Screws gradually settle in and hence they can
come loose. Therefore check the screws and
screws regularly if they are tightened appropriately with a torque wrench.
In the tables on page 88 and 89 you will find
the prescribed tightening torques, they refer
to greased screws!
Safety instructions
Final assembly
Caution! Screws must be tightened with prescribed tightening torque. In
this manual tightening torques are given in
"Nm“ (Newton meter). Always use a
torque wrench wherever a torque setting
is given in this manual. Never rely on "feeling". Screws tightened too much or not
enough can break, which can lead to dangerous accidents. In case you don't own a
torque wrench have your bicycle mechanic
do the respective work. You will find tables with the prescribed torque settings on
page 88 and 89 in this manual.
The grease also prevents your screws from
seizing in their threads so that they won't unscrew anymore. In particular, screws made of
stainless steel are susceptible to this and
therefore have always to be put in with
grease.
Do use high quality acid free grease, if possible
a lubricant with added solid particles like Teflon or MoS2. Their ingredients still work
properly after the thinner grease has been
removed from the contact surfaces.
Alternatively you can use thread locker that
you apply to the screw before you put it into
the thread.
Always check the screws very diligently for
signs of corrosion. Rust at the screw heads
may also lead to the screw seizing in the
thread. When the metallic and shiny coating
of galvanised screws comes off and discloses
dull, gray-brown steel you have to exchange
the screw.
When you exchange screws please only use
screws of the same type. Screws come in different strength classes. Please only use galvanised screws of the same type and strength,
corresponding to the German strength class
8.8 or stainless steel screws grade A2-70,
7
General safety instructions
when not given any other recommendation. If
you are in doubt please ask your specialist
dealer.
Quick release levers
Quick release levers hold wheels and seat in
position.
A quick release lever consists of two basic
parts: the lever on one side provides the
clamping force. With the adjusting nut on the
other side you adjust the clamping tension on
the screw thread.
Danger! An incompletely or improperly closed quick release can result in
parts coming loose and hence in a crash,
possibly resulting in serious injury.
To open the quick release, move the lever
away from the frame. In doing so the inscription "open" should be visible on the lever.
To close the quick release, move the lever
with power in the other direction so that the
word "close" is visible on the outward side of
the lever. At the start of the lever's motion,
for, say, half of its movement, the lever should
move very easily, without any clamping action.
In the second half of the lever's movement the
force on the leer should increase considerably, corresponding in the end to 15-20 kg (46
lbs).
In its final position, the lever should come
parallel with the tricycle and should not stick
out to one side.
Check the security of the lever by attempting
to twist the lever. If the lever can be made to
pivot around in a circle the clamping is too
loose. You must re-open the quick release,
hold the lever and increase the clamping tension. Do this by screwing the adjustment nut
8
on the other side by half a turn. Close the
lever and check the clamping anew.
Finally, check that the part being secured is
firmly fixed: Lift each wheel several inches off
the ground and give it a slap onto the tire
from above. A properly fixed wheel will remain secure in the frame's dropouts.
Parts that are fastened with a quick release
open easily. Thus, they are more susceptible
to theft. Therefore, always secure the wheels
with a lock when you park your tricycle. It is
also possible to exchange the quick releases
with special security screws (e.g. from Pitlock
or Kryptonite) that can only be opened with a
special tool. For this please consult your local
specialist dealer.
Danger! Check the proper setting
of quick release levers always before riding,
especially when the bicycle has been unattended.
The first miles
The first 300 km (186 miles) are an important
for breaking in the tricycle. During the first
use of a new tricycle the screws may settle
and become loose. Cables and spokes may
stretch. Bearings may show play. Please be
very attentive during that period.
After 300 km or after two months at the latest you will have to take your tricycle to a bicycle mechanic for the first service. Please
record this first service and the works performed in the warranty pass on page 91. This
first service is the prerequisite for further use
of the tricycle and for your warranty claims.
Legal requirements
When you ride your tricycle on public roads
it must comply with national legislation and
guidelines. They will vary from country to
country.
In general, there are minimum standards for
brakes, reflectors and lighting systems, as well
as usually a general duty to ensure that your
vehicle is in roadworthy safe condition. There
will also be a duty to ride in a safe and responsible manner. If you ride your
HP VELOTECHNIK tricycle in traffic you should
be sure to observe all the applicable laws and
regulations.
In most countries, including Germany and the
UK, two independent braking systems are required. Do not ride with only one brake
working! Please contact your local dealer to
find out about your legal obligations.
In the scope of German StVZO your equipment has to meet the following requirements:
x two functional, independent brakes
x a dynamo or battery driven lighting system
with a white headlight aiming forward
whose beam center touches the road 10 m
ahead
x a red taillight and a red rear reflector which
may be combined
x at least one white reflector aiming forward
and a red large area reflector with “Z” label
aiming to the back
x two yellow reflectors attached to the
spokes in every wheel; may be substituted
by tires or rims with white reflective ring
x yellow pedal reflectors on both sides fo the
pedals
x a bell
As an addition, we recommend to mount a
flag on a pole for better visibility in traffic.
You can find a bracket for the pole at the rear
rack or the rear light mount.
The safety equipment on your tricycle must
be checked before every ride and maintained
in proper condition.
Traffic regulations may change. Please check
currently valid regulations or ask your specialist dealer.
No alteration of parts
Caution! You are not allowed to
perform any work on the parts of the tricycle, especially frame, fork, handlebar and
seat, which might endanger their solidity.
These works include drilling holes, welding,
brazing, paint methods that add heat or
any other chemical treatment. If any of
these works is done improperly it may result in a loss of strength by direct damage
or increased susceptibility to corrosion.
Frame number and identification marks
The frame number is placed on the postions
described below. If needed, an additional identification number can be engraved at the described places on the frame.
However, we recommend to use adhesive
stickers for additional identification numbers.
Scorpion fs 26 /Enduro /S-Pedelec, Scorpion plus 20, Scorpion plus 26
The frame number is placed on the inner side
of the gusset plate at the main frame rear end.
For additional identification numbers on Scorpion fs 26 and Scorpion plus models, use the
area below the cable guidance on the upper
side of the seat tube (facing to the main
frame).

Caution! Mounting additional
parts or accessories is at your own risk. It
is important that you carefully read the installation guide of the manufacturer. Additions to the handlebar like fairings,
handlebar fittings, bottle holders, etc. may
impair your safety due to additional loading
or clips with sharp edges.
Additional accessories may impair the function of your Scorpion fs 26. We advise you to
generally ask your dealer before you mount
any special parts or accessories to your tricycle.

Take care that the handlebar and the suspension always stay moveable. You must not add
any parts to the handlebar or the seat that
might endanger the rider through sharp edged
or pointed shapes while steering, getting on
and off the tricycle or bumping against something.
Before you purchase a bell or a lighting system make sure that these accessories conform to your national laws and regulations.
Additional accessories may invalidate the operating licence or impair the function of your
S-Pedelec. This may also be valid for accesso-
ries and parts that are not in the category of
parts that can only be exchanged with parts
identical in construction. Before mounting
parts and accessories, it is recommended to
contact your bicycle dealer or a vehicle examination organisation (like TÜV, Dekra,
GTÜ...).
Check the special safety instructions for the SPedelec on page 13.
Fairings
As a front fairing for recumbent tricycle, you
may use the Streamer fairing offered by HP
VELOTECHNIK. Please take care to assure a
good vision over the fairing and sufficient
freedom of movement below.
Please take into account that any fairing makes
the tricycle more prone to crosswind influences. In strong wind or gusts of wind unsafe
situations may occur. Please remove the fairing before riding in such weather conditions.
Danger! If any part is deformed
(e.g. due to an accident or overload), especially frame, knuckles, handlebar, seat
mountings, pedals, cranks and brakes, it is
not allowed to use it any further or repair
it. Do not try to straighten bent parts. You
must replace them for your own safety. If
you do not replace a damaged part it can
result in a total failure of the part and you
may be seriously injured!
Do not take kids with you
HP VELOTECHNIK tricycles are not designed
for the transport of children. You are not allowed to mount a child's seat. It is only allowed to transport children in a trailer that
has been specially designed for that purpose.
Pedelec system
Instructions for the use and safety of the optional pedelec systems are referred in the systems manufacturer's manuals. Please read
them carefully before use.

Replacement of parts
The replacement of parts relevant for safety
(especially brakes, lighting system, stem, handlebar, knuckles, drive train, suspension elements) should only be done with original
parts by a bicycle mechanic, since it requires a
certain degree of skill, suitable tools and mechanical aptitude.
Any technical change you perform on your
own is at your own risk!
You are allowed to use trailers (double trail
only) up to 40 kg (88 lbs).
We recommend using a trailer hitch mounted

Legal requirements
According to law, the Scorpion fs 26 is not a
bicycle but a motor vehicle class L2E (threewheeled small motorcycles with a maximum
design speed up to 45 km/h). The construction speed, that is the speed that the vehicle
will reach without using muscle power, is 20
km/h. With additional power from the rider’s
muscles, up to 45 km/h can be reached. At
that speed, the motor assistance is switched
of completely.
To be allowed to use the S-Pedelec on public
roads, there must be an operating licence for
it and it must be equipped with a insurance

Handling instructions
Riding a recumbent tricycle
Learning the new riding technique
Your new tricycle has been assembled by
your dealer and adjusted together with you as
described on the pages 19 and following in the
chapter "Adjusting your new tricycle". Before
you sit down on your tricycle and enjoy your
first ride please make yourself familiar with
the instructions on riding technique and handling.
To ride this recumbent you will have to make
yourself acquainted with the different riding
position. Make sure that you and all other future users of this tricycle will have read this
manual carefully prior to the first ride. If you
are in doubt please consult your local dealer.
Before the first ride the users of this recumbent have to practice and make themselves
familiar with the different handling. We recommend to practice on a quiet road away
from traffic. Before you ride the tricycle in
traffic you must master the handling completely.
Caution! When getting on and
off the tricycle, make sure to avoid pulling
at the handle bars or stepping on the tie
rods. To get off the tricycle, sit upright on
the front seat edge and then stand up. Grip
the front wheels or the seat back as extra
support, not the handlebars. If you pull
firmly at the handlebars, the steering can
be damaged.
16
Danger! Never touch the
ground with your feet while the tricycle is
still moving. The feet could be caught on
the ground and be pulled backwards and
dragged under the cross bar which could
lead to a serious injury. We strongly recommend using a pedal binding system like
clipless pedals or toe clips and straps.
Keep all three wheels on the ground while
riding. If you are cornering too fast, your tricycle can be upset and fall over. Lean into
curves when turning sharply. At high speed,
keep your upper body quiet as any upper
body movements can influence the steering of
the tricycle.
Practice cornering away from traffic to learn
what speed is safe at a specific turning angle.
If you lift up a front wheel, immediately steer
in the opposite direction to bring it safely
back to the ground.
Danger! Please be aware that
due to your low seat height other road users may notice you very late. Ride anticipatory with this in mind. This is especially
important while riding in darkness. You
yourself have a much better view than
others perceive you. Ride defensively. We
recommend mounting a well visible and reflecting flag to the tricycle while using it in
traffic. Find more information about lighting systems on page 42. Please ask your
dealer for more information.
Riding a recumbent tricycle
Caution! Always carry your tricycle over stairs and curb stones. Do not
ride through big road holes. Especially
when road holes are filled with water it is
very difficult to guess how deep they really
are.
In case you hit such an obstacle frame and
steering may be damaged which can result in a
serious fall. At first, the damage may be unnoticed. Please check your tricycle immediately
for deformations and cracks. If you are in
doubt please consult your local dealer.
Do not ride freehand
Danger! In order to ride safely
you have to keep both hands at the handlebar. Even when signalling keep at least
one hand at the handlebar. Otherwise, unforeseen bumps in the road or oscillations
of the steering may lead to a serious fall.
How to ride correctly and safely
Always adjust your speed to the traffic, the
road and the weather conditions. Ride slowly
in curves and on unknown roads. Always ride
at a safe distance from other road users, and
when you ride in a group never ride side by
side.
When you approach a traffic light never ride
past the line of waiting cars since even the
most attentive car driver may not see you due
to your low riding position.
When riding the S-Pedelec, be aware of the
higher speed level this vehicle provides. It may
be unfamiliar for other people in traffic. Ride
defensively. Only ride at higher speeds where
and when this is safe!
Wear protective clothing
Riding a tricycle is a potentially dangerous
sport where accidents can happen even when
you take care of every safety instruction prescribed.
We recommend you to wear an approved bicycle helmet that fits well. Protect yourself by
wearing special sports clothing that fits tight
and is reflective. If you're wearing wide pants
use clips to protect them from getting caught
in the chain - or use an old fashioned method
and put the pants in your sockets.
When you fall with a recumbent you’ll usually
land on the side of your hips and your hands.
Wearing reinforced cycling shorts and gloves
reduces the danger of skin injuries considerably.
Use clipless pedals
The pedals of your recumbent tricycle can be
upgraded on demand with a binding system.
As soon as you are comfortable with riding
your Scorpion you should use those clipless
pedals. Due to the rigid connection between
shoe and pedal you don't have to keep your
foot on the pedals with pressure anymore.
This enables a more relaxed and round pedalling movement where you may even pull a little on the pedals. Without this connection to
the pedals your feet may come off suddenly
which may result in a fall. Modern system
pedals with binding therefore contribute to
safe riding.
At first you will have to practice with these
pedals to make sure that you can get off
quickly in a dangerous situation. Please read
the manual of the pedal manufacturer that
comes with this manual and have your dealer
explain the use of the pedals to you. In the
beginning set the release force of the binding
17
Handling instructions
How to ride correctly and safely
Riding a recumbent tricycle
to a low value to make sure you can get off
safely.
Please use exclusively the original shoe plates
/ cleats from the manufacturer of the pedals,
do not use any other brand. If you're using
shoe plates that are not authorised the binding system won't work properly.
Slowly increase the strain
We recommend you to perform only short
rides without much power during the first
weeks.
Always use a low gear and ride with a high
pedalling frequency. Only after having acquired some training do increase the strain
slowly.
When you ride on a recumbent you use different muscles than on a conventional bicycle,
and they have to be trained first. The very
high position of the bottom bracket requires
your muscles and blood transport system to
slowly familiarise with the new position.
In case of an overload the blood circulation in
your legs may be affected which shows in loss
of power, a prickling in the toes, falling asleep
of the legs or cramps. When you feature a
sporty way of riding it can take up to 6
months until you have become accustomed to
your new recumbent.
If there is pain in your knees occuring while
riding this is usually the result of too much
power put into pedalling. The good support of
the back sometimes misleads to putting the
full power of the legs in the pedal, similar to
the leg training machines in a fitness center.
When you repeat it regularly it is harmful for
the knees. Pain in the knees often results from
an overuse of the muscles in the knee that can
also be strengthened by exercise.
Also, a wrong adjustment of the front boom
to the leg length (in most cases too short) can
lead to pain in the knees.
18
Your position on the recumbent bicycle is essential for your riding comfort, well-being and
efficient cycling. Therefore you should adjust
the frame, seat, handlebar and suspension to
your individual requirements.
In order to adapt the bicycle as closely as possible to your body dimensions and to find
your ideal position you need to adjust the
front boom, seat and handlebars.
Danger! All procedures described here require a certain degree of
skill, suitable tools and mechanical aptitude.
After any adjustment perform a static
check and take a test ride on a quiet
street, away from traffic. If you have any
doubts please contact your local dealer.
The upper curve of the seat back in the area
of the shoulder blades determines the correct
seat length: Through this shape the shoulder
and neck area is lifted from the recumbent
position so that the head rests in a natural and
relaxed position. For this reason you shouldn't need a head rest if you have the right seat
position. On long rides, a head rest can increase your riding comfort as you can relax
your neck for a few seconds by leaning back.
You can mount our custom headrest to your
existing seat.
The seat is too small when you have the impression that your back is pressed too much
into a "hunchback". It is too large when you
have the impression that the seat angle is too
far leaned back when you are in the most upright position, or when you hit the upper seat
edge with the back of your head when you
look upwards.
If your tricycle is equipped with the optional
front boom-quick adjust, please read the instructions in the separate manual in addition
to the following instructions.
Adjusting the seat position
For all Scorpion models, there are two alternative Seats available: The BodyLink®-seat and
the ErgoMesh® seat. In the following, the detailed setting options for both seats are described.
On the Gekko models, the seat is integrated
into the frame and remains on the tricycle.

The adjustment of the seat length and the
proper seat angle is crucial for a comfortable
feeling while riding your recumbent.
Take off the seat cover (see page 21). Open
the quick release lever for the seat back angle

about 35° from horizontal.
Tighten all 4 screws with 5–6 Nm. Move the
seat back rest to the preferred angle and
close the quick release lever firmly. Reinstall
the seat cover
Adjusting the seat back angle is easy when you
push the seat back with your hands on the
backside close to the seat mounting into the
desired position. By pulling at the upper seat
edge, tension may be created which causes
the adjustment mechanism to lock up.
Caution! Do not loosen or
tighten the 4 screws in the lower seat part
to adjust the seat length. Maximum tightening torque of these screws is 3–4 Nm.
Because of the flexibility of the BodyLink®
seat and the special shape of the seat mountings, the seat effectively pivots around a central axis, approximately in the area of the
lower lumbar vertebrae. This is the place
where you support most of your pedalling
force while riding, so this point determines
the distance to the pedals. The advantage of
this design is that you adjust the distance from
the seat to the bottom bracket only once as
described above; a change in the seat angle
does not require an adjustment of the front
boom.
Caution! To avoid noise from
the seat when loaded, the contact surfaces between the two seat shells need to
be separated by self-adhesive plastic sheets
and all contact surfaces of seat and seat
mountings and frame need to be lubricated
with grease.
Length adjustment of the Airflow cushion
The optional Airflow-cushion consists of two
parts that connect in a V-type shape. Loosen
the Velcro mounting of the upper part, and
place it in the desired position, than fasten the
Velcro.
Adjusting the seat back angle
A great advantage of the BodyLink® seat on
your Scorpion fs 26 is the possibility to adjust
the seat back angle very quickly. For beginners
or rides in the city you can choose an upright
seat position for a better view, and for longer
rides you can choose a flat position for better
aerodynamics.
The seat back is fastened with a quick release
lever on a slotted aluminium seat mounting.
You can adjust the seat back angle by 10 degrees by simply opening the quick release le20
Adjusting the front seat edge
The front seat edge can be slightly lowered to
accommodate smaller riders. With a lower
front seat edge, it is easier to put your feet on
the ground without pressure from the seat
edge on the back of your legs. With a higher
front seat edge, the seat will give more support and avoid the feeling of „sliding down the
seat“ that occurs with upright seat angles.
To adjust the front seat edge, open the quick
release lever at both the lower and the upper
seat half, so that the seat is not under inner
tension. Thus you need less force for the adjustment. Push or pull the seat front edge
firmly to reach the desired position and close
the quick release lever firmly. Then adjust the
seat back angle as described above.
If the quick release lever pressure is to loose
when closed, open the lever and turn the
screw on the end of the quick release axle
clockwise. The low profile design of the screw
head gives more clearance for the drive train.
Adjusting the lumbar support
The BodyLink® seat is ergonomically shaped
and supports the natural S-curve of your spine. Forces from pedalling are supported in the
area of your lower back just above your hips.
The amount of support in this area (lumbar
support) is adjustable by moving the seat back
and lower seat against each other.
To get more lumbar support, lower the seat
front edge and put the seat back in a more
reclined position.
To get less lumbar support, rise the front seat
edge and put the seat back more upright.
For maximum adjustment, loosen the 4
screws for the seat length adjustment in the
seat back. Thus the lobes of the lower seat
part can move more easily into the desired
shape. Tighten the screws and quick releases
as described above.
Caution! The three quick releases have to be closed firmly (tightening
force 15-20 kg / 45 lbs) to safely hold the
seat. You must not open them while riding.
After they have been closed the imprint
"close" must be visible. If the quick releases
are not properly tightened the seat can
move while riding and you may lose control over your tricycle.
Please pay attention to the instructions
about quick release levers on page 8.
Seat cushion
The standard seat cushion consists of a 1,4 cm
thick layer of flexible EVA foam. This is a black
foam material with closed cells that is also
used in the production of high quality camping
mats. It feels very comfortable without appearing too soft or spongy. It is waterproof so
you can dry your seat with a sweep of your
hand in case your bicycle has become wet.
In order to take off the seat cushion lift up the
upper part a little bit from the seat. Then you
grab the cushion on both sides together with
the end of the Velcro that sticks out slightly
and remove the cushion slowly. In case the
Velcro comes off fasten it again with a good
glue.
Caution! The seat cushion is fastened with Velcro and you can take it off.
For this purpose it is important not to
simply grab the foam and take it off since
the Velcro could come off.
Caution! Never expose the seat
cushion to extreme heat or focused
sunlight. The material warms up considerably. The heat may melt the glue of the
Velcro. The seat cushion can be damaged
when the rays of the sun are bundled
through a lens. Take care to never leave
any bubble wrap on the seat in the sun.
The air bubbles in the film act like a burning glass and shrink the seat cushion.
For better ventilation, the Airflow Cushion is
available as accessory. This cushion consists of
several layers: A rigid mesh and a soft mesh,
which provides for an approximately 1 cm
thick air cushion with excellent circulation.
These two layers are wrapped up in a cover
that consists of fine mesh like it is known
from high quality rucksacks. You can wash the
Airflow Cushion at 30° centigrade and it dries
very quickly.
The seat cushion suffers from wear by constant use. The mesh parts under punctual
pressure can be pressed together permanently after some time of usage. In order to
still provide a good riding comfort, the Air21

than the standard versions. They are meant to
give strongly build persons a comfortable seat
option.
The ErgoMesh® plus versions
The ErgoMesh®-plus seats have been designed
to simplify getting on and off the tricycle.
With a plus of 11 cm seat height compared to
the ErgoMesh®-standard seats, they give you a
better overview in traffic.
Caution! When using the ErgoMesh® plus seats, be careful when riding
through bends. Due to the increased
height the tricycle may tend to tip over
easily.
Adjusting your new tricycle
Your Gekko is equipped with a mesh seat
which needs not to be removed for folding
the tricycle. Using eight straps, the seat surface can be adjusted individually to your back.
The backrest angle is fully adjustable with a
quick release. The seat is ergonomically
shaped and supports the natural S-curve of
your spine. Forces from pedalling are supported in the area of your lower back just
above your hips. The seat is bowed up in this
area (lumbar support). The adjustment of the
seat mesh and the proper seat angle is crucial
for a comfortable feeling while riding your recumbent.
The Gekko mesh-seat remains on the tricycle when folding
Adjusting the seat mesh
By means of eight straps on the backside and
underside of the seat frame the tension of the
seat mesh can be adjusted according to your
needs. If the seat feels too soft, you sink in
too far at one spot or you sit on the seat
frame you’ll have to tighten the straps in that
area. If there is some spot where the seat
feels too hard and uncomfortable or you
don’t have enough lateral support you’ll have
to loosen the straps in the respective area.
You can use gripping pliers to tighten the
straps in case the force you can apply with
your hand is not enough. To loosen a strap
the semicircular side of the plastic connector
must be lifted to release the strap out of the
connector.

The head rest
Both seat types can be equipped with a head /
neck rest which is adjustable in height and angle.
To relax the muscles in your neck on long
rides you can purchase a head / neck rest to
mount on the seat frame. Its height and inclination is adjustable at the clamp. Wearing a
helmet the headrest pad should be positioned
under the lower helmet edge next to your
neck. Adjust the inclination in a way that the
headrest does just not touch your neck/head
while riding. It may be necessary to cut the
two tubes protruding the clamp on the underside to prevent them from touching your
back.
Use the long holes and the screw hidden under the cushion (BodyLink®-seat) or the
mounting clamp (ErgoMesh®- and Gekko seat)
for setting up the correct position. (There is
also a mounting clamp with quick-release levers available.) It may be necessary to cut the
two tubes protruding the clamp on the underside on ErgoMesh®- and respectively Gekko
head rest to prevent them from touching your
back.
Caution! Do not push or carry
your tricycle on the head rest, this may
damage the head rest or the seat!

frame where the cranks are mounted) in the
main frame.
seat distance on a recumbent can be slightly
longer than on a conventional bicycle.
While you are pedalling, the ball of your foot
should be positioned above the centre of the
pedal axle.
It is important that your leg is not fully
straightened when the crank is in the foremost position. If the distance is too long it is
difficult to overcome this dead point, pedalling
becomes uncomfortable and there is too
much strain on the sinews of your feet and
legs. If the distance is too short you may suffer from knee pain.

Unscrew the bolts M8x35 under the main
tube with a 6 mm Allen key. Take a grip on
the front derailleur tube or both cranks and
move the front boom further into the frame
or pull it out while cautiously turning it.
Before you pull out the front boom shift the
chain to the smallest chain ring and sprocket.
Turn the cranks a little bit backwards while
pulling. Thus the chain is not under tension.
Caution! When you move the
front boom take care that its end does not
damage any light cables that possibly come
out of the main frame. Please inform yourself about the length of the front boom on
your tricycle before you do any work.
While moving the front boom you also
have to move the light cables The light cable must never be stressed by pulling.
Caution! After you have unscrewed the clamping bolts take them off
and examine them for deformation. Lubricate threads and heads thoroughly. Then
re-fit the bolts. If they don't turn easily you
will have to replace the bolts.

Handling instructions
Adjusting the front boom
Adjusting to your size
For riders with short leg length the front
boom has to be cut by a bicycle mechanic, so
it can be inserted maximum possible. It is important to trim the end of the tube neatly.
The bare metal of the shortened tube end has
to be protected against corrosion with a paint
stick or wax spray.
The maximum insertion of the front boom is
limited by possible heel cycle of the frame’s
cross bar, depending on the rider’s shoe size.
Please check before riding your tricycle that
there is enough heel clearance. For shorter
riders under 175 cm body height we recommend to use shorter cranks.
On the left underside of the front boom there
is a fine line. Align this line with the sticker on
the main tube’s front end right above the
clamping bolts to adjust the bottom bracket
axle to a horizontal position. Additionally, you
can look beyond the bottom bracket shell at
the rear wheel axle and align the front boom
parallel to it. Align your eyes with the bottom
bracket axle and not the front derailleur tube.
Then sit down on your tricycle and check the
position.
Caution! The minimum insertion
depth of the front boom into the main
frame is 8 cm (3 1/5"). The end of the front
boom must not be visible in the clamping
slot when you look at the main frame from
below, since this may result in a damage of
the frame.
26
The rear end of the front boon must never be visible in
the clamping slot.
Tighten the bolts with a torque wrench
(tightening torque 14–16 Nm). On your first
ride check whether there is sufficient clamping.
The plastic bush between front boom and
main frame must be visible at all time.
Adjusting to your size
Danger! After the chain has
been shortened it must be closed with a
special closing link or a chain riveting tool
that expands the rivet while riveting (i.e.
Rohloff- Revolver). A poorly joined chain
may break and thus lead to damage or injury. Chain length adjustments or chain
changes should be done by your bicycle
mechanic.
We recommend to slightly readjusting the
front boom every 3 months so that knees in
order to provide a slightly different position
to your muscles and ankles. You might also
find a more comfortable and more efficient
riding position.
Danger! If the bolts are tightened too much or bent, the screw or the
frame can break! If the clamping is insufficient the front boom can turn during a ride
which may cause your feet to slip from the
pedals and lead to injuries.
After moving the bottom bracket tube your
dealer has to adjust the chain length. By default the Scorpion fs 26 comes with a very
long chain so the adjustment range of the tricycle can be fully used without the need to
lengthen the chain.
After the basic adjustment of the leg length
done by your dealer before handing over the
tricycle, the chain has to be shortened so that
the derailleur cage is not fully turned forward
while shifting on the largest chain ring in front
and the smallest sprocket behind. The derailleur must still be able to compensate a length
change of the chain of at least 4 cm (1 1/2"). In
Check that there is at least a 5 cm (2") clearance between the end of the chain tube and other parts of the
drive train
A wrong adjustment may lead to pain in your
knees and inefficient pedalling. In addition we
recommend riding with a high pedalling cadence, which means to pedal fast and with little pressure. Pedalling with too much pressure
may also lead to pain in the knees.

Handling instructions
Danger! There must be a bushing (a slotted tube of plastic with edges to
the front and the clamping slot) in the main
frame’s front boom hole that is glued in
the frame. This bush ensures safe clamping
of the front boom and protects the paint.
It is important to take care that this bush is
always visible at the front end of the main
frame. The lower slot has to be aligned in
coincidence with the slot in the main
frame. If this bush is missing or moved to
the back of the tube while inserting the
front boom, safe clamping is no longer
guaranteed, even if it seems to be the case
at first glance. If the front boom is not
clamped properly it may turn and lead to a
fall. A missing or misaligned bush will lead
to frame damage.
order to choose the right chain length, please
consult the manual of the derailleur manufacturer.
Adjusting to your size
Caution! Take care that the
chain tubes have a clearance of at least 5
cm (2") to the rear derailleur and the front
derailleur even under maximum tension of
the chain and make sure that the tubes are
held tight in their fastenings. The front upper tube can be moved to the rear for
length adjustment. Shorten the tubes if
necessary. If the end of the chain tube gets
in touch with the rotating chain rings it can
be locked-up and destroyed. The chain
tubes must be prevented from moving by a
rubber tube over the retention spring.
Adjusting the length with front boom
quick adjust
The front boom quick adjust is additional
equipment for HP VELOTECHNIK recumbents
that feature a telescopic front boom for leg
length adjustment. It replaces the standard
bolts of the front boom clamping by quick release levers. Two pulleys provide chain length
compensation while moving the front boom.
First, shift the chain to the largest chain ring
and the largest sprocket to check the correct
chain length.
Open both quick release levers. Slide the
front boom into the frame or pull it out until
you’ve reached the required frame length.
To slide the front boom in, grip the cranks
and turn them against the tensioned chain.
The force on the chain helps to move the
front boom into the frame tube.
To pull the front boom out, grip the derailleur
tube if available. If you pull at the cranks, you’ll
have to turn them backwards at the same
time, else the tensioned chain will balk the
motion.
Moving the front boom is easier when turning
it a little bit from side to side. When doing
this, make sure the pulley bracket doesn’t
scratch the frame and its lug won’t be bent.
That’s why we recommend to only turn the
front boom clockwise (and back afterwards)
when looking from the front.
Align the bottom bracket axis horizontally
when looking from the front. Close both
quick release levers.
Move the chain to the smallest chain ring and
the smallest sprocket. Check the chain length.
The rear derailleur cage should not be completely swivelled to the back to still apply tension to the chain.
Please pay attention to the instructions about
quick release levers on page 8.
Routing of the chain over the idlers of the front boom

The front boom must be clean and free from
wax or tenacious remains of chain lube to
make sure it can be easily slid in and out.

Adjusting the handlebars
While riding you should allow your arms to
rest in a relaxed position on the handlebars.
Do not push or pull on the handlebars. If the
handlebars turn in the stem clamping during
the ride stop immediately and tighten the
clamping screw of the handlebars. If the handlebars are not sufficiently clamped the handlebars or the stem may be damaged or
deformed. In this case, safe clamping can no
longer be guaranteed, not even with the correct tightening torque, and handlebars and
stem have to be replaced.
Caution! When getting on and
off the tricycle, make sure to avoid pulling
at the handle bars or stepping on the tie
rods. To get off the tricycle, sit upright on
the front seat edge and then stand up. Grip
the front wheels or the seat back as an extra support, not the handlebars. If you pull
firmly at the handlebars, the steering
mechanism can be damaged.
Setting the width and angle on
Scorpion, Scorpion fx, Scorpion fs,
Scorpion fs 26 /S-Pedelec /Enduro,
Scorpion plus 20 /26
The handlebar consists of two parts. They are
mounted to the stem by a slotted clamp on
each side. The adjustment range in width is
3.5 cm on each side, giving a total range of 7
cm (aprox. 2 ¾").
Most riders are comfortable with an 85° angle
so that the bent grips point upwards and
slightly forward. The more upright the grip
position and the narrower the handlebar
width, the larger the minimum possible turning circle as the handlebars touch your legs or
the seat earlier.
In order to change the angle or the width,
loosen the screws of the stem/handlebar
clamping. Move the handlebars until they are
in your favourite position. Tighten the clamping screws with 8–10 Nm. Check the correct
clamping of the handlebars by sitting down on
your tricycle and pulling the handlebars. The
handlebars must not turn in the stem.
Danger! If the handlebar grips
are adjusted pointing too far forward or
too wide, your hands or the brake levers
can touch the front wheels or mudguards
when cornering sharp, leading to injury.
Make sure you have at least 5 cm (2“)
clearance between brake levers and front
wheels / mudguards at all steering angles.

the cables or replace them by longer ones.
Caution! After having adjusted
the handlebar position you have to readjust the length of the brake cables and
shifter cables. The cables have to run
smoothly without any sharp turns and they
should not be bent sharply or stretched
when the handlebar is at maximum angle.
Also avoid large bows that could be caught
up by the front wheels or other parts or
touch objects under your tricycle.
Cover all contact areas where cables move
and touch the frame with sturdy transparent
tape. This protects the paint against scratching
and wear.
Handlebar grips
Handlebar width is adjusted at the stem clamp under
the seat.
The grips on the handlebar are susceptible to
wear and tear. Have your grips replaced by
your bike shop once they don't feel comfortable any more. The grips always need to be
attached firmly to the handlebar.
Danger! Please take care that
the clamping area of the stem is thoroughly
trimmed and there are no sharp edges
which may cause handlebar failure.
Adjusting the cable length
You can make smaller adjustments by moving
the cables in their guides at the frame and the

Folding
Taking off the seat
First step when folding a tricycle out of the
Scorpion family, the seat needs to be removed.
Open all three quick release levers of the seat
mountings: Unscrew the nut of the upper seat
quick release approximately 4 turns. Turn the
quick release levers of the middle and lower
seat quick release counter clockwise approximately 4 turns.
With a water bottle mounting installed, space
is limited and it may be easier to hold the
quick release lever and turn the flat nut on
the right side (chain side) of the seat mountings with a 5 mm Allen key.
Pull the lower seat half out of its mountings,
then the upper seat half. After dismounting
the seat tighten the quick release again to the
quick release axle from bending when the
folding buffer touches the frame.
Caution! When storing the seat,
please take care not to bend or break the
seat mountings. Protect the edges of the
seat mountings with padding to avoid
scratching other objects with the seat
mountings.

Lighting system
Lighting systems for bicycles
If you want to ride your tricycle on public
streets, it must be equipped with a legal light
system. Do not only use your lights in the
dark but also in the twilight of dusk and dawn.
Due to laws and regulations the brightness of
bicycle lights may be considerably lower than
that of other vehicles. Therefore always keep
in mind that other road-users may only see
you very late or not at all.
For the bicycles, HP VELOTECHNIK offers a dynamo light systems with a tire dynamo or a
hub dynamo. The S-Pedelec lighting system is
powered by the propulsion system’s accumulator, which is also available for bicycles with
GO SWISSDRIVE pedelec system.
Both light systems come with strong LEDs for
headlamp and rear light. The LEDs last considerably longer (approx. 100.000 working
hours) than a light bulb. For your safety the
light system has a parking light system both at
the front and at the rear light, which makes
the LEDs shine on approximately 10 minutes
after you have stopped riding. The electronic
system is maintenance free. Because of the
capacitors used you don't have to worry
about batteries.
The cables and the contacts can be affected by
corrosion or mechanical damage. Therefore,
check the light system before every ride.
42
Tire dynamo
You turn on the light system with the tire dynamo at the rear wheel by unlocking the
swivelling dynamo. For this purpose you press
the red button at the dynamo until it moves
towards the rear wheel. To turn the light off,
swivel the dynamo back to its initial position
by hand.
Danger! Do not try to move the
dynamo while riding, your hands can be
caught in the wheel and be injured! To
turn the light system on or off stop riding,
get up from your tricycle and only then
move the dynamo.
Danger! The dynamo must always be safely fastened to the bracket at
the frame, so that it can not turn. If the
screws come loose the dynamo can get
caught in the spokes and block the rear
wheel - danger of a serious fall! Always
check the position and secure attachment
of the dynamo before a ride.
You can adjust the pressure of the dynamo
against the wheel with the turning knob at the
side. The pressure is right when the dynamo
wheel just does not slip at the wheel, if the
light flickers, the pressure is too low and you
have to increase it. The dynamo should be
positioned in a way that the extension of the
dynamo axle points through the center of the
wheel. Take care that the dynamo is mounted
safely and can’t be turned. Worn dynamo
wheels can be exchanged. Please ask your
specialist dealer.
Lighting system
The lighting system with a hub dynamo is
switched on electrically. For this purpose you
will find a switch on the back of the rear light
with three labelled switch positions. With the
switch you can turn the lighting system ON,
OFF or set it to SENSOR. In the SENSOR position a twilight sensor in the lamp turns the
lighting system on and off automatically depending on the brightness of the environment.
For the hub generator light system and battery powered
light systems on pedelecs and Scorpion fs 26 S-Pedelec,
there is an integrated switch at the front light to turn
the lights on and of.
You switch on the tire dynamo by pressing the red button. To switch off the dynamo move it away from the
wheel.
The SON hub dynamo is highly efficient and
works silently. When the dynamo is turned off
it has a very low turning resistance. Although
you can feel the single poles of the used permanent magnets very distinctly when turning
it by hand the real rolling resistance is minute.
(The loss is below 1 W at 15 km/h / 9,5 mph.)

danger of accidents!
Only ride your S-Pedelec with accumulator
installed. Without accumulator lighting system
and brake light are out of function. The lighting equipment according to S-Pedelec regulation is not sufficient to use the S-Pedelec as a
bike according to German StVZO rules even
during daytime.
Please pay attention to you countries regulations for public traffic!

Brakes
Your tricycle is equipped with a powerful
high-quality braking system. Please read the
separate manual of the brake manufacturer
that comes with your tricycle for details.
Make yourself familiar with the braking system.
In the standard assembly, both front wheel
brakes are operated separately: The left brake
lever operates the left front brake, the right
brake lever operates the right front brake.
As an option, your tricycle can be equipped
with a coupled braking system with one brake
lever operating both front brakes.
Danger! Make sure to brake
evenly using both hands. Braking unevenly
or only one side could influence the steering of your tricycle. Maximum braking performance is only achieved when braking
with both hands.
Danger! In case you get into a
situation like that during an emergency
stop you have to let go of the brakes immediately, balance your tricycle and brake
again. If you are not familiar with the
brakes we recommend you to train at first
at low speed and with little braking effect
until you find the correct dose for an
emergency stop.
If your tricycle is equipped with a rear brake
or a parking brake, use this brake only as an
emergency brake in the unlikely event of a failure of the front brakes. If the rear wheel is
locked up, the tricycle can immediately spin
around and slide to the side. Remember
which lever pulls the front brake and which
the rear brake.
Try to avoid braking in bends, though if necessary, touch the brakes carefully! Braking increases the risk of slipping. Especially when it
is wet the rear wheel immediately slides out
of the bend while braking and this can result
in a serious fall!
For optimum handling some braking systems
provide the option to adjust the distance between the brake grip and the handlebar with a
small hex-headed screw at the grip, please see
the respective manual for details.
The braking effect of modern braking systems
can be more powerful than what you have
been used to until now. Brake carefully. When
you brake too hard with the front brake the
rear wheel may lift off the street and the tricycle may tumble over.
If you should hear any unusual sounds while
braking the brake pads might be worn out. Do
not use your tricycle any further until you
have checked the brake pads according to the
manual of the brake manufacturer or before
having you tricycle checked by your local specialist dealer.
Danger! Please note that the
braking distance is much longer when it is
wet or when the tricycle is heavily loaded.
When riding on wet, sandy, icy or slippery
roads you have to use the front brake very
carefully to avoid that your front wheels
slip. If they do so you will no longer be
able to control your tricycle, which might
lead to a serious crash.

locks the pulled lever. To release the parking
brake, pull the brake lever.
Danger! Always make sure that
the disc or rims and brake pads are free of
oil and grease. If these parts are dirty
please do not use your tricycle. You can
clean oily discs with alcohol or a special
spray. Oily brake pads have to be replaced.
If you are in doubt, please have your specialist dealer maintain your braking system.
Riding with contaminated braking systems
can result in serious accidents!
Danger! Disc brakes can overheat on long down hill rides, fade and fail!
On down hill rides, do not brake constantly, but in several intervals with higher
pressure. If you notice that the brake
power starts to fade, stop immediately and
let your brakes cool down.
Danger! Never touch neither
the brake disc nor the brake caliper after
long braking as this may cause serious injury (risk of burns).
New braking systems, new brake pads and
new brake discs need a break-in period to
achieve maximum brake power. This period
lasts for about 30-40 stops from about 30
km/h (20mph), which should be done in a safe
area without traffic.
Parking brake
Always secure your tricycle against rolling
away when parked.
In the standard assembly, the brake levers are
equipped with a parking brake-button that
46
As an option the tricycle can be equipped
with a parking brake that is operated with a
thumb-shifter mounted at the handlebar. It is
connected with a V-brake at the rear wheel.
Make sure to fully open the parking brake before you start riding.
Maintenance of the brakes
Caution: Always read the brakes
manufacturers manuals carefully before doing any maintenance or repair jobs on the
brakes! Here you can find detailed information and pictures of how to do it!
The brake pads suffer from wear due to friction and have to be exchanged then. Depending on riding conditions, they can last between
a few hundred up to several thousand kilometres. Please read the manual of the brake
manufacturer carefully.
Check before every ride:
x that the braking system does not have any
damages or leaks by activating the lever,
holding it and checking the hose connections for possible leaks.
x that the brake lever pressure is ok by pulling the lever and ensuring that full braking
performance is achieved before the lever
touches the handlebar. If this is not the
case, adjust the cable or change the brake
pads, for hydraulic disc brakes pull the lever
several times (pump) until it feels firm.
x check the hydraulic braking system for the
correct pressure by pulling the lever, holding the pressure and checking the hose
connections, bleeding screw and compensating tank for possible leaks.
Brakes
Caution! Keep the brake cable
clean where it is not protected by the cable housing. Due to the mounting position
of the brake lever, moisture and dirt may
enter the cable and cause drag and excessive wear. Lubricate the ends of the cable
to protect against moisture.
Caution! Damaged cables with
single wires sticking out have to be replaced immediately. Otherwise your braking system may fail
Danger! Please take care that
the cable ends are always protected with a
cap. Always keep the cables shortly
trimmed. Leaving too much cable extending past the cable anchor can result in the
cable catching in the rotor or wheel causing the wheel to lock up.
The brake pads of your brakes are worn
when you can pull the lever further and further to the handlebar before the pads touch
the rim.
To compensate the wear of the brake pads
you can tighten the cable with the adjuster
barrel where the cable touches the brake
lever. First loosen the locknut, then unscrew
the barrel so far that the wheel still turns
barely not touching the pads, hold the barrel
and tighten the locknut again towards the
brake lever housing. Take care that the barrel’s slot points downwards to prevent moisture from entering.
Mechanical disc brakes
To readjust the brake pads you have to use
the big red knobs on each side of the brake
caliper. Adjust the inner and the outer pad
evenly. In case you are not sure, have this adjustment work done by a qualified bicycle mechanic.
Check your brake pads frequently as explained in the manual supplied by the brake
manufacturer. Worn brake pads, oily or damaged pads must be replaced immediately by a
qualified bicycle mechanic.
Hydraulic brakes
Danger! All maintenance work
on the hydraulic system of your brakes
may only be carried out by a qualified
technician. In case these works are carried
out without the required knowledge and
skills the braking system might fail which
can lead to a serious crash.
Hydraulic brakes on HP VELOTECHNIK tricycles
use low viscosity mineral oil that, contrary to
DOT brake fluid used in cars, does not absorb water. Thus, you don't have to change
the oil. Please read the brake manufacturer’s
manual that comes with the tricycle.
In case of a damaged hose or any leakage of
oil always consult a qualified technician in a
bike shop.
Hydraulic disc brakes
Hydraulic disc brakes feature a fully automatic
pad wear adjustment. Brake pads and discs
are subject to wear, therefore regularly check
the thickness of your brake pads and discs and
replace them if necessary. The minimum
thickness of the brake pad is 1 mm, of the
brake disc it is 1,7 mm. For further and more
detailed information on your disc brake model

Brakes
please refer to the brake manufacturer’s manual.
Danger! The hose at the left
knuckle must not be routed under the
track rod. This may lead to snapping off
the hose. The hose should leave the caliper
slope upwards and run in a wide bow to
the track rod. The zip ties fixing the hose
to the track rod must be tightened properly to prevent it from moving.
WRONG! The bow of the hose is routed under the track
rod: Danger of snapping off the hose (cf. arrow).
RIGHT: Lead the wire in a wide bow to the track rod.
Check clearance when steering left and right
48
Danger! If the brake pads or the
brake disc are worn out (pads: thickness
less than 2,5 mm including metal back, disc:
thickness less than 1,7 mm) the pads may
be torn out of the caliper while braking.
This leads to total loss of brake power.
Caution! Never activate the
brake lever with the brake pads not in
place or with the wheel dismounted.
When you transport the bicycle without
wheels always use the transport clips delivered with your tricycle or put a piece of
cardboard in the brake caliper to replace
the disc. Carefully separate brake pads that
have moved together with a screwdriver.
Caution! Keep the brake lever
clean. Due to the mounting position, water
and dirt can collect inside the lever around
the hydraulic cylinder. This may lead to excessive wear or leakage of the hydraulic
system.
Gear system and chain
With the gear system you can adjust the pedalling frequency, i.e. the number of revolutions
of the crank per minute, to the terrain and
the desired speed.
Your pedalling frequency should stay between
80-100 revolutions per minute and not fall below 60 while going uphill. If necessary consult
your local dealer and have him adapt the gear
range to your style of riding.
Your Scorpion fs 26 comes standard with a
derailleur gear or with an internal hub gear
system. The following section refers to the
derailleur gear system only. Please also refer
to the manual of the gear manufacturer.
You operate the gear changer with the grip
shifters or bar end shifters on the handlebars.
The right lever for the rear derailleur has an
index derailleur system that positions the
chain always on the chosen sprocket, so that
you don't have to "search" for the gears.
The left barend shifter is not indexed so you
have to adjust the front derailleur while shifting by slightly moving the shifter to stop the
front derailleur from dragging against the
chain while pedalling.
Riding a recumbent requires foresighted gear
shifting. Before stopping you should timely
change in a low gear to make it easy to start
off again, without having to pedal heavily.
You should only change the gears while you
keep pedalling, smoothly and without applying
great force, all the time that the chain is moving between the sprockets.
Caution! Under no circumstances allow the tricycle to roll back while
changing the rear gears, or try to pull the
tricycle backwards when the gear shifter
lever has been moved, as this will damage
the rear derailleur.
Due to the long cables that expand under
pressure and the housing that compresses under pressure it may be helpful for changing
gears quickly to turn the bar end shifter a little bit farther than necessary to select a gear
and turn it back to the indexed position once
the chain has properly shifted ("overshift").
When the chain length has been properly adjusted you can choose every combination of
front chain rings and rear sprockets to shift
gears. However, it is useful to ride the lowest
gears (the biggest rear sprocket) with the
smallest chain ring, the middle gears with the
middle chain ring and the highest (fastest)
gears with the biggest chain ring.
The setup of the chain rings and sprockets
leads to an overlap of some gears. This means
that different combinations of chain rings and
sprockets can result in the same gear ratio. It
would be possible to arrange a gear system so
that double gears do not occur but this requires a lot of concentration when you shift
gears while riding, since you will always have
to change the rear sprockets as well as the
front chain rings. If you would like to change
the setup of your gears please consult your
local dealer.
49
Handling instructions
Handling of the gear system
Gear system and chain
Danger! Practice shifting gears
on a traffic-free street. In the course of this
make yourself familiar with the functioning
of the bar end shifters. Doing this in traffic
could distract your attention from possible
dangers.
Adjusting the gear system
Your dealer will adjust your derailleur gearing
system carefully before handing over the tricycle. But during the first 300 kilometres (186
miles) of riding the cables can stretch, making
the gear indexing imprecise. The chain then
climbs only hesitantly onto the next sprocket.
Caution! Please read the manual
of the gear system manufacturer carefully
before working on the gear system.
Adjusting the gear indexing for the rear derailleur
Adjust the adjuster barrel where the shift cable touches the rear derailleur. Do it in small
steps of half a turn.
Check after each adjustment whether the
chain moves smoothly up to the next larger
sprocket. To do this, either turn the cranks by
hand or ride the tricycle.
When the chain climbs up easily, you need to
check that it still goes down easily onto the
smallest sprocket. If necessary turn the adjuster barrel a little more and then try shifting
gears again.
50
Danger! If the chain shifts over
the smallest or the biggest sprocket you
have to readjust the end-limit adjusters of
the rear or the front derailleur. Incorrect
adjustment can lead to the chain coming
off, getting stuck or damaging the spokes,
which may result in serious falls. The adjustment of the end-limit adjusters is a job
for a professional bicycle mechanic.
Danger! If the tricycle falls over,
the derailleur or its mounting can be bent
which results in a change of the derailleur
movement range. Check the movement
range and have it readjusted by your bicycle mechanic, if necessary.
All moving parts of the gear system are affected by wear. Cleaning and lubricating these
parts frequently can prolong the life of these
parts. However, they will have to be replaced
once worn out.
The cables have to be checked, cleaned and
serviced regularly. Expect more wear and
corrosion when the tricycle is often parked
outside in bad weather conditions.
Caution! Damaged cables that
show for example single wires have to be
changed immediately. Otherwise they may
damage your gear system. Take care that
the ends of the cables are protected with
fitting caps.
Gear system and chain
The chain is a wearing part that has to be lubricated regularly and to be changed at signs
of excessive wear and tear. The amount of
wear depends on maintenance and care as
well as on the circumstances of your ride
(rain, dirt, salt). Regular cleaning and lubricating can increase the chain’s lifetime, nevertheless the chain has to be changed when its
wear limit is reached.
Lubricating the chain
Diligent lubrication is important. The chain of
your Scorpion fs 26 is approximately 2.5 times
longer than a standard bicycle chain (approximately 3.8 m). But it also lasts longer
since a chain only wears while bending at the
sprockets and the chain rings.
Use good chain oil that won't leave a sticky
film on the chain. The chain oil must not contain any aggressive chemical substances that
might affect the surface of the chain tubes or
chain idler.
Specialist stores sell biodegradable lubricants.
HP VELOTECHNIK recommends a DryLubetype lubricant. This lubricant is purely based
on PTFE (Teflon) that keeps the chain clean
and dry. This way dirt simply falls off and the
tubes always stay clean.
It is important that you clean the chain with a
cloth before lubricating. Otherwise the fresh
oil washes the dirt that clings to the chain into
the gaps and the bushings where the dirt
causes heavy wear.
Do not use any solvents to clean the chain!
The solvent washes the oil off the bearing
parts, stays there and dilutes the fresh oil so
that a sufficient lubrication is not guaranteed.
If you have treated the chain with a solvent
you will have to heat it up with a hot air gun
or boil it in chain grease.
Danger! Take care not to pour
any oil on the rims, brake discs or the
tires. The braking system could fail or the
tires could slip away suddenly. The oil affects the rubber of your tires and can damage it. While lubricating cover the
surrounding area.
An effective protection against corrosion is
crucial for a long chain life. Some minutes after you have oiled the chain rub it with a cloth
to remove superfluous oil from the outer surface. Wax the chain thoroughly with a wax
spray. The wax keeps off water, protects from
corrosion and makes dirt fall off easily.
If the chain has become wet after riding in the
rain you should put your bicycle in a dry and
heated room, and every day you should turn
the crank and so move the chain until it is dry
again. Otherwise it is difficult for the moisture
in the tubes to evaporate which may lead to
corrosion at the chain.
Replacing the chain
The chain is one of the parts of the tricycle
that will wear out. This shows in a stretching
of the chain. Worn out chains do not fit the
sprockets and chain rings any more and wear
them away very quickly.
Check the chain for lengthening regularly. For
this purpose, try to remove the chain from
the chain ring. The chain may come off to a
maximum of 5 mm. For a more precise reading you can buy a chain measurement gauge in
your bicycle shop.
Only use chains that are suitable for the gear
system of your tricycle. Otherwise a precise
gear shifting is not guaranteed any more.
Please consult your dealer on this topic. He
will also assist you in checking your sprockets
and chain rings. A new chain does not fit a

links by KMC. Every time you change the
chain you also have to apply a new joining link.
Make sure that any chain links in the chain are
not stiff, as this can cause some annoying and
not obvious problems with the gear system.
Make sure that you have not twisted the chain
180 degrees before joining it back together.
Caution! When you change the
chain take care that the new chain does
not show any sharp edges or burrs.
HP VELOTECHNIK delivers spare chains by the
meter via your dealer. For this purpose please
indicate the exact length of your chain or order it a little bit longer if you want to be sure
it fits. You will need approximately. 3,8 m of
chain.
The chain length has to be fitted so that the
arm of the derailleur is not fully stretched
when you shift on the big chain ring in front
and the big rear sprocket. The derailleur must
still be able to compensate a shortening of the
chain by 4 cm. Please also see the manual of
the derailleur manufacturer on the choice of
the correct chain length.
Caution! The chain has to be
closed with a special joining link or a chain
riveting tool that expands the ends of the
rivet while riveting (Rohloff revolver). A
poorly joined chain may break, you can
come off the pedals and fall. If you are in
doubt please have adjustments of the chain
length or the changing of the chain be done
by your bicycle mechanic.
Take care that the joining link is not bigger in
size than the other chain links to avoid irregular chain sounds. We recommend the joining
52
Chain tubes
The chain protection tubes are made of a long
lasting plastic that features very low friction,
slow wear and good noise damping. The tubes
protect your clothes against the chain oil as
well as the chain against dirt from the road.
The upper tubes are fastened with an interchangeable retention spring, the lower tube
runs through an adjustable clip.
The tubes are worn by the chain and have to
be cut at the ends and expanded again (or exchanged) after 3.000-5.000 km approximately,
depending on the chain type and the overall
riding condition. You can extend this maintenance interval by turning the tubes by a quarter turn from time to time so that they do
not keep wearing out in the same place.
The intensity of the wear depends mainly on
the chain type. Please see also the instructions
on "Chain" on page 51.
In order to perform any work at the chain
tubes you'll have to open the chain and finally
close it again. Please see the instructions on
"Chain" on page 38.
The distance of the upper chain tube to the
chain wheel can be adjusted by sliding the
tube in the retention spring. It must be secured with the rubber tube over the spring.
Gear system and chain
Caution! The rear ends of the
upper chain tube have to be secured
against moving with a tight rubber tube
over the retention spring. Without the
rubber tube the chain tube may be dragged
forward into the turning chain roller or
chainring and thus be damaged by the
chain.
Caution! Check the chain tubes
frequently if they are damaged or defective.
Replace defective chain tubes immediately.
If the chain tubes are worn in the area of
the retention spring or tube mountings,
the chain will touch the retention spring,
leading to failure of the spring and mountings. As a result, the chain tube can get
into the drive train and block it!
Expanding the tube ends
The ends of the tubes are expanded like a
trumpet so that the chain can enter smoothly
without friction and without making noises.
When the ends are worn out you can renew
them by expanding them again. Remove the
Heat the last 5-10 mm at the end of the tube
with a gas burner, a hot air gun, or a candle
and turn it permanently until the colour of the
utmost edge turns from a dull black to a shiny
black. Now you expand the end with a proper
tool, e.g. the rounded grip of a screwdriver.
Quench the expanded end immediately with
cold water.
Take care that the tubes don't catch fire. At
any rate work in a place with sufficient ventilation. If the tube is too short after you have
cut it so that there is not enough protection
anymore it has to be replaced. You can buy
spare tubes either as uncut tubes or already
cut into the correct length, complete with retention spring from your specialist dealer.
Replacing the tubes
In order to exchange single parts in the upper
chain tubes cut the old tube at the retention
spring at the chain roller and pull the remaining part off the spring. Now move the smooth
part of the new tube through the spring and
rubber tube, then expand the tube end as described above.
Changing the complete upper chain protection or the retention spring
Remove the bolt in the chain roller with an
Allen key 6 mm. Take off the chain roller, the
washer and the chain retention hook.
The end of the threaded tube in the frame is
protected with a plastic tube.
Take the retention spring off this plastic tube
and put on the new retention spring. Turn the
spring so that the retention springs run under
the spacer to the tubes and the wires lie between frame and chain tube; that way the spirals face outwards.

Handling instructions
Caution! Take care that the
chain tubes keep at least a 5 cm distance to
the rear and front derailleur when the
chain is stretched to the maximum, and
that the tubes are well fastened. If necessary you will have to shorten the tubes. If
the end of a chain tube gets into the rotating parts of the drive train the drive train
can be blocked and the chain tubes may be
destroyed.

Gear system and chain
Push the bolt back through the chain roller,
the washer and the chain retention hook, secure the thread with Loctite and tighten the
bolt with 17-19 Nm. The recessed side of the
chain roller has to face to the frame. Make
sure the washer is placed between chain
roller and plastic tube / frame.
Changing the lower chain tube
The chain tube is connected to the mounting
plate by a rubber sleeve. For dismounting the
chain tube, grab the sleeve on its rear end and
pull it together with the chain tube to the
rear. The rubber sleeves will release the rear
tongue of the mounting plate then. Swivel the
chain tube sidewards. Having done that pull
the chain tube to the front to release the
sleeve from the front tongue of the mounting
plate. Replace the chain tube and mount it by
following the above steps vice versa.
Chain roller
The chain roller guides the chain below the
seat to the rear wheel and is an essential part
of the HP VELOTECHNIK No Squat design. It
ensures that the suspension is not influenced
by pedalling.
Compared to other models the chain roller
has a big diameter and it has a higher area in
the middle to make the chain move as
smoothly as possible. Due to this higher area
the chain does not lie on the roller with its
sharp edged links but with the bushes in the
middle that work like small bushings. In addition to a very low rolling resistance it also
supports a quiet chain movement. A chain retention hook between the frame and the
chain roller locks the roller at the bottom and
keeps the chain on the roller when you pedal
backwards.
54
Chain roller, chain hook and chain tubes on
Scorpion fs 26
The chain roller wears slowly and gradually
shows a sprocket shape in the higher area in
the middle. When this middle area is worn
completely the links of the chain will run on
the roller. In that case you will notice that the
chain makes more noise while running and
you should change the roller. You can purchase the plastic part without the bearing or
the complete roller through your dealer.
The bearings must not be treated with a jet of
water from a high-pressure cleaner or with
solvents since this may destroy the sealings
and remove grease from the bearings. If the
bearings don't move smoothly anymore you'll
have to replace them.
Caution! The roller comes with
two maintenance free sealed bearings. The
bearings are exchangeable. Between the
bearings there is a spacer that keeps the
correct distance. If you forget to put in the
spacer after you have dismounted the
bearings they will be destroyed when you
tighten the screw while remounting them.

Handling instructions
Caution! If this chain retention
hook is missing the chain may fall down.
When you start pedalling then the chain
roller, the seat or the frame may be damaged through the chain. Please consult
your local specialist dealer in case this
hook is missing.
Dismounting and mounting of the chain roller
To dismount the chain roller, the chain tubes
need to be removed. See also hints on replacing the chain tubes (page 53)
The chain roller is mounted with a special
high strength screw of the German strength
grade 12.9 and it may only be replaced by a
screw of the same type and strength.
The chain roller is not symmetrically shaped;
the recessed side of the chain roller has to
face to the frame, the flat (logo) side outwards.

Wheels
Disassembling the front wheels
Disassembling the rear wheel
To remove a front wheel, loosen the bolt in
the locking part at the inside of the knuckle at
least 6 mm. Pull the locking part away from
the knuckle. Pull the wheel a few mm away
from the knuckle and slide the axle through
the slot in the knuckle.
Rear wheels can be fastened with a quick release mounting and therefore they are susceptible to theft. For this reason always lock the
wheels along with the frame to a solid object
when you park your bicycle somewhere.
Please pay attention to the instructions about
quick release levers on page 8.
Tyres
The correct air pressure is decisive for
smooth running and a good protection against
punctures. The maximum pressure is printed
on the sidewall of your tire. You might find an
indication of the minimum required pressure
on the sidewall of the tire as well.
Since the tubes in the tires gradually loose air
you should check the air pressure before
every ride.
1: Loosen the screw in the locking part
The tubes come with Presta valves (also called
french valves). They are very airtight and easy
to pump up.
To do so, first screw off the valve cap. Now
you see a small threaded rod with a knurled
nut that comes out of the valve. Loosen the
knurled nut as far as it is possible.
2: Taking out the front wheel out of the knuckle
Take care not to bend the brake disc. When
reinstalling the wheel, slide the disc carefully
between the brake pads and take care not to
damage them. Tighten the screw in the locking part with 8–10 Nm.
56
To pump up the tire and check the pressure
you need a pump with a gauge, preferably a
solid floor pump. Put the knob of the pump
on the valve, push it completely on the valve
and then retract it a little bit. Now you can
pump up your tire easily.
After you have pumped up the tire to the desired pressure pull off the pump knob. Secure
the valve by turning the knurled nut on the
threaded rod properly against the valve body.
Finally put on the valve cap again.
Wheels
Danger! Never pump up your
tires beyond the maximum pressure. The
tire may burst while riding or come off the
rim, which may result in a serious fall and
injury.
On the rear wheel you have to use a tire of
ISO size 559 (26"). The tire width possible at
your bicycle depends on the size of your rims.
Please ask your local dealer.

Wheels
Spokes
The spokes of the wheels connect the rim to
the hub. They transmit the braking power of
the disc brakes, and in addition they transmit
the pedal forces at the rear wheel.
The tricycle requires a high spoke tension
(> 1000 N) as the wheels have to bear high
side loads. Any damaged spokes must be replaced immediately.
Caution! To true up the wheels
you need special skills, please have this
work done by an experienced bicycle mechanic.
Danger! Take care that your
spokes are always in perfect condition and
the spoke tension is balanced. Do not ride
with wheels that run untrue or wheels
with loose or missing spokes. These faults
may lead to a total failure of the wheel
while braking and result in a serious fall!

Headset
The knuckles that connect the front wheels to
the frame are supported by A-Head-type
headsets. (The following informations are only
valid for tricycles without front suspensions.
For those, please refer to page 73).
The headsets must be adjusted in order to let
the knuckles with the front wheels attached
turn easily without showing play.
To check the bearing play, pull the front brake
and grab the upper bearing cup with your
other hand. Now move your tricycle back and
forth. If the bearing has play the upper cup
moves noticeably in contrast to the fixed part.
In this case loosen the clamping screw of the
clamp above the upper bearing and tighten the
screw in the cap a bit more. Afterwards, fasten the clamp again.

Gekko fx 26
Both front wheels should be parallel to each
other, viewed from above the tricycle, compare picture below.
The condition of the front ends of the front
wheels being closer together than the rear
ends of the front wheels (bv smaller than bh) is
called toe-in, the condition of the front ends
of the front wheels being further apart than
the rear ends of the front wheels (bv larger
than bh) is called toe-out. The measures are
taken at wheel axle height on the rim sidewalls.
If the front wheel alignment is incorrect, you
will suffer excessive tire wear and increased
tire drag. Check your front wheel alignment
regularly. The proper tolerance on toe-in is
0–2 mm (1/16“). For correct measuring properly trued wheels are required.
To check the toe setting, turn the handlebars
into the neutral position, so that the wheels
are aligned straight forward. Measure the distance between the front inner or outer edges
of the front wheel rims and the rear inner or
outer edges of the front wheel rims 25 cm
(10“) above the ground.
The distance between the front edges bv must
be 0–2 mm (1/16“) smaller than the distance
between the rear edges bh.
60
It is important to measure the distances at the
same height of 25 cm (10“) above the ground,
as the front wheel are not exactly perpendicular to the ground, viewed from the front of
the tricycle. Measuring at varying heights results in measuring errors.
Measuring toe setting on Scorpion fs,
Scorpion fs 26 /Enduro /S-Pedelec,
Scorpion plus 20 and Scorpion plus 26
The distance between the front edges on full
suspension tricycles bv must be 0–2 mm
(1/16“) smaller than the distance between the
rear edges bh. If toe-in is checked in unloaded
condition, the proper tolerance is 2–4 mm
(1/16”–1/8”). Then, the correct value is
reached under normal riding conditions with
the front wheels deflected by ca. 20 mm.
The adjusting procedure in other respects is
the same as for models without front suspension.
Adjusting toe setting
The front wheels are held by suspension
struts which can turn at the ends of the main
frame. The suspension struts are connected
by tie rods to the handlebar stem.
The rod ends consist of ball-and-socket bearings that can be screwed in or out of the tierod for length adjustment. Length adjustment
is done at the inner tie-rod end, at the con-
nection to the handlebar stem. The outer rod
end is screwed completely into the rod and
secured with thread locker. Do not try to
turn this side of the rod end.
First make sure that the handlebar is aligned
perpendicular to the main frame tube. Identify
which wheel (or perhaps both wheels) needs
adjustments of the toe-in by measuring the
distance between rim wall and main tube on
the most forward point and on the most
backward point of the rim (value av and ah in
the picture). The distances should be roughly
identical for one wheel.
Remove the bolt that connects the inner rodend to the handlebar stem, note the washer.
Caution! Do not move the rodend beyond its limits, or it will be destroyed or get excessive play. Always hold
the rod end with a wrench or secure the
tie rod with a wrench against turning when
tightening the lock nut
Hold the rod-end with a wrench and loosen
the nut that is screwed against the rod-end.
Screw the rod-end into the tie-rod to enlarge
the distance bv between the front edges of the
front wheel. Screw the rod-end out of the tierod to decrease the distance of the front
wheel edges.
Danger! The rod-end must be
screwed at least 8 mm into the tie-rod. If it
is screwed out to far, the thread could tear
out and the tricycle could become unsteerable. This means that with a standard
length of the thread of the rod-end of 24
mm, a maximum of 11 mm visible free
thread length is allowed between rod-end
and lock-nut.

Danger! The lock nut must be
screwed tight to the tie-rod, otherwise the
rod-end could loosen up or play could develop. Please pay attention to the table of
fastening torques in page 88
Align both rod-ends parallel to each other.
Grip the rod-end with a wrench and tighten
the nut against the tie-rod with 4–5 Nm.
Attach the tie-rod to the handlebar stem:
First, the screw is put through the hole in the
stem (from upside to downside).
Then slide the washer and the rod end onto
the screw. Finally, put on the self-locking nut.
On the other side of the track rod the rod
end is mounted on the underside of the suspension strut’s steering lever. Between strut
and rod end there is a washer and a spacer.
There is an additional spacer between screw
head and rod end.
Measure the toe-in as described above. Repeat the adjustment process until you reach
the required toe-in setting.
Caution! Make sure the washer is
between rod end and bracket to allow the
full movability of the rod end.
Danger! Secure the thread of
the bolt with Loctite adhesive. Check all
connections of the steering system before
every ride. If a connection loosens, the tricycle becomes unsteerable which may lad
to serious injury.

Setting of camber- and caster angle on full suspension tricycles
Setting of camber angle on Scorpion fs,
Scorpion fs 26 /Enduro /S-Pedelec,
Scorpion plus 20 and Scorpion plus 26
(informations for bicycle mechanics)
The McPherson axle on the full suspension
tricycles is equipped with adjustable
wishbones. By adjusting the rod ends on the
wishbones, the required axle specifications
can be met. During assembly in our factory,
the front axle was adjusted correctly. In case
of replacement of worn-out or damaged parts
the front axle needs to be readjusted. In
unloaded condition, the following adjustment
values must be met:
x
x
x
x
toe setting: 2–4 mm toe-in
camber angle: +0,5° (+0,5°/-1,5°)
max. difference in camber angle le./ri.: 0,5°
caster angle: 76,7° (+/-1°)
(us = 40 mm). The upper measure so between
rim wall and square should be 36 mm
(+0,5°positive camber) now and must be in a
range of 32 (+1° positive camber) to 48 mm (1° negative camber). The difference between
the measure so on the left and right wheel
must not exceed 4mm.
Caution! Always check the front
axle specifications after accidents or unintended events such as riding through a
deep road hole or contact with the curb at
higher speed as well as after replacing axle
components. An incorrect adjustment can
lead to increased tire wear and uncontrollable handling.
For measuring, the tricycle must stand on a
plane, non-inclined floor.
For adjusting works, the tricycle should be
mounted in a work stand, best upside down.
The stabilizer bar must be disassembled.
To measure the caster angle, the front wheels
must point straightforward. Attach a protractor to the front side of the fender bracket.
Align the protractor perpendicular to the
ground. Make sure the protractor only
touches the fender bracket and not the
frame’s headtube.
To adjust the front axle both rod ends of one
wishbone must be disassembled from the
frame. Loosen the counter nuts and screw in
or out the rod ends according to the table on
the left. Values in between can be interpolated.
To measure the front wheel's camber angle
position a long square next to the wheel concident with the wheel axis. Set the lower distance between rim wall and square to 40 mm
Check the values after provisionally reattaching the wishbone and wheel on a plane floor.
Repeat the adjustment if necessary.

Suspension and damping of Scorpion,
Scorpion fx, Scorpion fs, Scorpion fs 26
/Enduro /S-Pedelec, Scorpion plus 20
and Scorpion plus26
The rear swing arm is suspended with a steel
coil spring in the standard version. The optional rear shock ROCKSHOX Monarch uses air
as spring medium.
Rear suspension and full suspension tricycles
allow compensation of bumps and roughness
of the track for advanced comfort and reduce
forces on the tricycle.
The damper slows down the process of compression and expansion. That means the tricycle does not immediately "spring" back to the
initial position or even further than that after
having passed a bump. The damper converts
spring energy into friction and finally into heat,
and thus takes away energy from the suspension system. The damper prevents the spring
from swinging uncontrolled after an initial
stimulation. In addition, the damper helps to
avoid self enforcing oscillations of the suspension caused by recurrent stimulation like pedalling forces within a crank revolution or the
rhythmic up and down movement of the legs.
A well-adjusted suspension improves the traction of your tricycle on uneven roads. Especially when riding in a bend this allows a
higher speed and also improves safety.
In order to achieve maximum riding comfort,
the suspension settings have to match your
weight as well as the road condition.
The goals of the adjustment are:
x maximum use of the available suspension
travel without the suspension frequently
bottoming out
x quick reaction of the suspension without
obvious oscillation after having passed a
bump
x avoiding self enforcing oscillations, that
means increasing oscillations of the suspension system due to pedalling influence,
rhythmic body movements or permanent
wavy underground
The improvement of road holding the suspension gives you a plus of safety.
In case you have mounted the optional suspension element ROCKSHOX Monarch, the hydraulic damping of the rear suspension is
adjustable. The more you increase the rebound setting, the slower the system comes
back to the normal position after a compression.
Danger! While adjusting the rear
suspension element never load the tricycle
e.g. by resting on the seat or loading the
rear rack when your hands or tools are
close to the suspension element. Your
hands may get caught and squeezed when
the suspension compresses.
The suspension system of the rear swing arm
consists of a spring and a damper.
Adjusting the suspension
Often, the terms suspension and damping are
used inaccurate in everyday language.
You should always set the damping as low as
possible to give the tricycle the possibility to
quickly react even to several bumps in a row.
The spring is the elastic element that compresses and expands due to the load changes,
which e.g. occur on bumpy roads. While expanding, the spring releases the same energy it
took to compress it.
You can ride the Scorpion fs 26 with a considerably lower damping rate than for example a MTB: due to the relaxed and steady
position of the body the recumbent does not
65
Handling instructions
Adjusting the suspension
Adjusting the suspension
experience extreme variations in the load as it
is known from dancing on the pedals while
riding uphill on a mountain bike.
In addition to this, varying pedalling forces
have very little influence on the suspension of
the tricycle due to the No Squat design of the
suspension system of the Scorpion fs 26. So
when you adjust the damping, always start
with a low damping rate.
It is necessary to choose the correct spring
stiffness to have a well operating suspension
system. The spring stiffness is a measure for
the compression of a spring at a certain load.
It is either given in "N/mm" (Newton per Millimetres) or "lbs./inch" (Pounds per Inch).
Sometimes you only find "lbs." printed on the
springs.
The spring stiffness of the optional air shock
ROCKSHOX Monarch is set by adjusting the air
pressure.
The suspension is designed in a way that the
spring is compressed partly when you sit
down on your tricycle. This is called negative
suspension travel (or "sag") and it enables the
spring to expand on bumpy roads. (This is in
fact a definitely positive feature.) You should
choose a spring stiffness with which this negative suspension travel takes up around 30% of
the overall suspension travel. This value usually provides a very comfortable ride on your
suspended recumbent tricycle.
Adjusting to load
The luggage carrier of your recumbent tricycle is mounted to the suspended part of the
frame. That way your luggage is also fully suspended and it spares the material. Most notably, even under heavy load the suspension will
compensate an uneven road much better and
quicker compared to a design where the luggage carrier is mounted to the unsuspended
parts, e.g. the rear swing arm.
66
Additional luggage changes the load on the
wheels and their suspension. The springs are
further compressed initially through the load
and there is less suspension travel for bumps
while riding. Your suspension will bottom out
more often.
The suspension of the front wheel is less affected since luggage at the rear rack almost
only puts weight on the rear wheel. Only in
case of heavy luggage on the lowrider under
the seat there is an influence on the front
wheel.
In order to compensate the variations in the
load you can change the pre-load. For details
see the following chapter.
Theoretically adjusting the preload can compensate for a load change of approx. 10 kg (23
lbs) at the rear wheel. In case of higher variations in the load you will have to exchange the
spring with a spring with different spring rate.
In practice you can often do without it: With
a suspension travel of 80 mm on the rear (and
60 mm on the front of full suspension tricycles there is a lot of suspension travel for a
touring tricycle. When you choose the spring
rate to have the full 80 mm at your disposal
when your recumbent is under maximum
load, you will have a somewhat smaller but
still very comfortable suspension travel when
you ride without luggage. The optional air
shock ROCKSHOX Monarch can be easily
pumped up to compensate load increases.

Danger! While adjusting the rear
suspension element never load the tricycle
e.g. by resting on the seat or loading the
rear rack when your hands or tools are
close to the suspension element. Your
hands may get caught and squeezed when
the suspension compresses.
For the rear suspension a spring element is
combined with a hydraulic damping unit in a
suspension element. The damping results from
fluid friction of oil flowing through thin holes
of a valve in between two chambers inside the
damper. A slightly noticeable sound that may
occur from this oil flow is normal. Due to the
fluid friction the spring element may heat up,
therefore touch the spring element after a
ride only very carefully.
Danger! The suspension elements are filled with gas under high pressure. Never try to open the damper or to
remove the screw at the gas tank. Inside
the damper there are no user serviceable
parts. In case of damage you will have to
take the complete suspension element to
your dealer.
The Scorpion fs 26 comes standard with a
steel spring rear shock. As an option you can
get the air shock ROCKSHOX Monarch that
uses air as spring medium.
Adjustment
The preload determines how far the suspension compresses when you are sitting on the
tricycle while standing still.
Therefore it is necessary that you have the
correct spring stiffness according to your
weight. (On page 69 you will find more information about changing the springs).
Measure the distance between the two suspension element bolts or between rear rack
and rear wheel while the tricycle is unloaded
as well as while sitting on the tricycle in riding
position. Also take into account possible luggage. Find out the total suspension travel possible for your tricycle with the method
described above, depending on the mounted
add-on-parts and clips on the piston rod. The
static compression should amount to about
one third of the overall suspension travel.
You can affect this negative suspension travel
depending on how much you weigh and how
much you load your tricycle either by adjusting the suspension pre-load for fine tuning or
by replacing the spring with a spring with a
different stiffness in the rough tuning.
In order to adjust the suspension pre-load
turn the adjustment ring on the threaded part
of the suspension element by hand. Turning
the adjustment ring clockwise (looking at it
from behind) reduces the preload, turning it
counter clockwise you screw the adjustment
ring towards the spring and increase the suspension pre-load. It is helpful to turn the
spring together with the adjustment ring.

Handling instructions
Steel spring rear shock DV-22
Rear suspension element
Danger! Take care that the rear
wheel or mudguard or suspension element
never hit the frame, seat, rear rack or luggage box while the suspension is fully compressed.
Steel spring suspension element with fixed damping
rate.
Danger! The adjustment ring has
always to be screwed on so far that the
spring has no play when unloaded. Otherwise the adjustment ring could come loose
through shocks while riding and the slotted
rear spring retention disc comes off. In
that case the suspension element may be
damaged or the rear wheel can hit the
frame or rear rack, which may lead to serious falls. Always have an initial preload of
at least half a turn on the spring.
Therefore relax the spring completely by
turning the spring retention disc on the
thread of the spring element as far as possible (before this, push the possibly existing
safety spring ring from its slot in the
threaded section as far as possible). Have a
second person sit down on the tricycle and
make the suspension bottom out by leaning on the seat or the rear rack.
If the distance between the wheel or mudguard and the frame, seat, or rear rack is
smaller than 1 cm you will have to mount
an additional spacer. In case you don't, the
mudguard may break suddenly or the rear
wheel might be blocked which can lead to
serious crashes.
The adjustment ring should be turned not
more than five turns (measured from the relaxed position) towards the spring. If the suspension compresses still too far even after six
turns, the spring is too soft and has to be replaced by a harder spring. A too high preload
with a too soft spring will not take advantage
of the full comfort potential.
The suspension travel is adjusted by adding clips to the
piston rod of the spring element.
68
Rear suspension element
You can buy the spring for the rear suspension element in different spring rates at your
dealer.
We recommend the following spring rates,
depending on the overall weight:
Load
Spring stiffness
x up to 80 kg:
x up to 110 kg:
x up to 140 kg:
450 lbs/inch
550 lbs/inch
650 lbs/inch
In addition to this, your dealer can also use
springs with other spring rates or special
lightweight springs made of titanium.
In most cases the rate is printed onto the
spring. Pay attention to the correct imprint
since the term "B650" that sometimes occurs
does not necessarily mean 650 lbs./inch!
Spring length:
DV22: 83 mm (70-90 mm)
In order to change the spring you will have to
remove the rear screw and swivel away the
rear frame.
Hold the main frame of your bicycle in a work
stand.
If there is a safety ring at the thread of the
suspension element move it to the end so you
can unscrew the adjustment ring completely
and then turn it to the outer position at the
end. Remove the slotted spring retention disc
at the other end.
Loosen the screws of the rear suspension
element with two Allen keys and push the
screw out of the suspension element’s eye.
Danger! If the bicycle does not
stand on the ground while undoing the
screws of the suspension element the rear
swing arm may come down uncontrolled
afterwards and hurt you seriously. In addition to this the cables of the gear system
and the brakes may overstretch and you
will have to replace them. Ensure that the
rear swing arm comes down in a controlled and gentle way by putting up a solid
string or zip tie between the main frame
and the rear swing arm.
Danger! When the bicycle is
standing on the ground the frame and the
swing arm come up against each other.
Please make sure that this happens in a
controlled and gentle fashion. Put a cloth
between the contact surfaces. Otherwise,
if they come up against each other uncontrolled your hands may get caught between
main frame, rear swing arm and suspension
element and your bicycle may be damaged.
Move the rear swing arm down carefully.
While doing this, take care that you don't
bend or stretch any cables.
Remove the spring from the suspension element and put on the replacement spring.
Make sure the new spring has the same diameter and length as the old spring and that it
is supported safely by the adjustment ring.
Put back the slotted spring retention disc on
the piston rod. If necessary, compress the
spring a little bit. The spring retention disc has
to match its support at the end of the suspension element.

damper. The internal oil can become foamy.
This may lead to some noise when the
damper is working. This noise does not affect
the function of the damper. Only if there is no
obvious damping after the first 5 mm of travel,
the damper should be replaced.
Please also note the maintenance instructions
of the damper manufacturer provided with
your tricycle.
After having exchanged the spring you have to
readjust the spring preload as described in the
chapter on "Adjusting your new bicycle" on
page 19.
Cleaning and lubricating
Do clean the suspension element, especially
the polished piston rod, if it is dirty. Remaining dirt and sand can damage the seals of the
hydraulic system and so shorten its life considerably. We recommend you to protect the
suspension element from dirt with an elastic
cover that you can buy at your local dealer
when riding on dirty roads regularly.
From time to time grease the thread for the
spring pre-load with a drop of acid-free oil.
Thus, you can always turn the adjustment ring
easily by hand. Once a year you have to
grease the pivots of the suspension element.
For that purpose dismount the suspension
element as described under "Changing the
spring" on page 69.
Remove the plastic spacers and pull the metal
tube out off the bushing. Lubricate the bushing
and the tubes with grease. Finally remount the
suspension element.
Hydraulic dampers are affected by wear and
tear through normal use. It depends on the
usage of the tricycle, the amount of dirt on it
and the maintenance and lubrication. After
3000 km the damper must receive an inspection by a trained mechanic, worn out parts or
the hydraulic cartridge can be replaced then.
Due to wear of the seals oil can leak from the
70
The bushings of the rear spring element need to be lubricated once a year.
Air shock ROCKSHOX Monarch
Caution! Please follow the instructions in the separate manual provided
by the rear shock manufacturer.
This rear shock contains pressurized air in a
main („positive“) air chamber as suspension
medium. Air shocks are lighter than steel
spring rear shocks. Another advantage is that
the spring stiffness can be easily adjusted with
an air pump: By increasing the pressure the
spring becomes harder.
Air shocks have progressive spring behaviour,
whereas steel springs have linear spring behaviour. This means that the air shock gets
progressively harder, e.g. it is much stiffer
when fully compressed than when only slightly
compressed.
The advantage of this progressive spring behaviour is the good bottom-out protection
when heavily loaded.
The valve for the air chamber is located at the
back end of the air shock. The valve is protected by a metal valve cap.
Danger! Take care that the rear
wheel or mudguard or suspension element
never hit the frame, seat or rear rack box
while the suspension is fully compressed.
To pump up the air shock you need a special
air pump designed for bicycle air shocks. It
must feature a fitting Schrader valve adaptor
and a pressure indicator.
Therefore fully deflate the air shock. Have
a second person sit down on the tricycle
and make the suspension bottom out by
pushing on the seat or the rear rack.
When attaching or removing the pump
to/from the valve, you will lose some air pressure (about 0,5-1 bar). Take off the pump
quickly.

Adjusting the damping
By adjusting the damping you can adjust the
performance of the suspension precisely to
your individual riding situation. A rough street
with many harsh bumps that occur in a row
or even cobblestones needs a low damping
rate while a road with long stretched bumps
that occur more regularly needs a stronger
damping to achieve a smooth road holding.
When you add a lot of luggage you will need
to adjust the spring stiffness; in that case an
adjustment of the damping may even give you
more riding comfort.
Finally, the oil used in the damper becomes
thicker and more viscous at lower temperatures, which can be compensated through a
change in the damper setting.
Please note that you can seriously spoil the
riding comfort by a bad damper setting, especially caused by unsystematic playing with the
knobs that may result in much to high damping values. In the worst case the suspension
71

Rear suspension element

element will neither compress nor decompress. If you are in doubt please consult your
local dealer.
The rebound damping prevents an eventual
"jumping" of the rear wheel and provides a
good traction. By improving the road surface
contact the suspension of the Scorpion fs 26
also increases your riding safety.
A higher damping value prolongs the time until the decompression movement is finished.
Only then can the suspension compensate the
next shock with the full suspension travel.
Therefore, when you ride on very bumpy
streets with shocks that occur fast in a row
you might want to use a lower damping value.
Caution! When mounting the Air
shock to the frame, take care to place it in
correct position: The lever must not get in
contact with the frame or swing arm when
the shock is being compressed.
On Scorpion fs 26 tricycles, the blue lever
must be on the rear facing upwards.
On Scorpion, Scorpion fx und Scorpion fs
the blue lever must be on the rear facing
downwards.
A good setting for maximum comfort is
achieved when the rear wheel decompresses
completely after a shock and then oscillates
only once. In order to check the adjustment
you will need a second person that compresses the suspension by pushing the tricycle
down while you are sitting on the tricycle in
the riding position. The other person can then
observe the suspension movements.
In order to adjust the damping during decompression, turn the adjustment knob on top of
the rear end of the suspension element.
Air Shock ROCKSHOX Monarch damping is adjusted with
the red knob at the rear end. Watch correct mounting
direction depending on your model! (Lever facing upwards on Scorpions 26" models and downwards on
Scorpion 20" models)
72
If you turn the knob in direction of the „-“
you will get less damping and thus faster decompression. Turning the knob in direction of
the „+“ will give you more damping and thus
slower decompression.
Adjusting and maintenance on the front
suspension of Scorpion fs, Scorpion fs 26
/Enduro /S-Pedelec, Scorpion plus 20
and Scorpion plus 26
Danger! While adjusting the
front suspension, never load the tricycle,
e.g. by resting on the seat or loading the
racks when your hands or tools are close
to the suspension struts. Your hands may
be bruised when the suspension compresses.
Full suspended tricycles of HP VELOTECHNIK
are equipped with a suspended front axle. It is
designed as a so called McPherson strut. That
means, the left (or right) suspension strut's
upper end is supported in the frame while it is
linked to a single wishbone on its bottom end.
The front wheel is directly attached to the
suspension strut, which is the knuckle at the
same time.
Inside the suspension strut a steel spring is
combined with MCU-elastomers. The front
suspension is damped by friction between
stanchion tube and a circular elastomer band
situated between the bushings as well as by
friction inside the elastomers.
To decrease body roll in during fast cornering
and to provide high comfort at the same time,
the front axle is equipped with a stabilizer bar.
This bar is linked elastically with both
wishbones and the main frame. As the stabilizer bar works as a torsional spring, it supports the outside wheel's suspension while
cornering.
Your tricycle has reached a sag of 20 mm
when the upper edge of the knuckle which
you can feel underneath the shock boot coincides with the lower edge of the head tubes
of the main frame. You can fine tune this sag
according to your weight and your additional
luggage by adjusting the preload of the springs.
To change the spring rate in a wider range,
you can replace the steel spring or interchange elastomers and spacers inside the suspension struts. For further instructions, please
see the chapter "Adjusting the suspension" on
page 65
To adjust the preload of the front suspension,
unscrew the strut end cap using a hex key size
5. Now the preload adjuster is visible, which
can be turned by a hex key size 5, too.
Turn the preload adjuster counter clockwise
to decrease preload, turn it clockwise to increase preload. The maximum depth is limited, so stop turning when resistance rises
suddenly. After adjusting, place the cap on the
strut and tighten it gently (1-2Nm).
Hex head screw for adjustment of the pre-load for the
spring inside the knuckle
For maximum comfort, 30% of the suspension
travel should be used when you sit on your
tricycle in a normal driving position (the same
is valid for the rear suspension). For the Scorpion fs 26 front suspension, this means 20 mm
of travel (so called "sag").

Make sure the adjusting disc's thread is
fully screwed into the stanchion tube. Otherwise it may become loose and hurt you.
The damping rate can be altered by exchanging the elastomer bands inside the suspension
struts, see “Removing and disassembling the

shows the characteristic of the suspension
setup.
The characteristic is referred to as linear
when the curve of suspension force related to
suspension travel forms a straight line. Force
and travel are related to each other by a constant factor, called spring rate, throughout the
whole suspension travel. This is a typical characteristic of steel springs.
The characteristic is referred to as progressive (or rising rate) when the spring rate increases with suspension travel. In the diagram,
this results in a curve with a left bend. Due to
their design, elastomers and air springs show
this characteristic (MCU elastomers show an
almost linear characteristic in the first part of
their travel, see curve nr. 4).

The tuning of your suspension bases on the
choice of the steel spring according to your
usual load. The soft spring moves the area of
operation to low rider and luggage weight, the
hard spring to high rider and luggage weight.

steel spring. (Setup: spacer-spacer-elastomerelastomer-elastomer)
Varying the number of elastomers and their
relation to the number of spacers inside the
steel spring changes the area of operation as
well as the suspension characteristic. It is allowed to have one or more blank spaces out
of the five spaces available for elastomers or
spacers. In this case the load during the first
part of the travel is only taken by the steel
spring and the elastomers only affect the suspension after the travel of the blank spaces is
used up.
Will your tricycle always face the same load
and only high quality roads, for example, you
may tune your suspension characteristic to a
more linear behaviour in the first two thirds
of travel and a high progression in the remaining third. The linear part provides very high
comfort. The progression at the end prevents
the strut from frequently bottoming out due
to unusual high loads.
Caution! Do not install more
than two spacers in one strut, otherwise
the full suspension travel can not be
reached. Spacers should always be installed
at the top of the stack inside the spring to
give room for the screw in the top cap.
The setup must be similar in both suspension struts of your tricycle.
If you use your full suspension tricycle under
different conditions and changing loads as well
as on good and bad surfaces, a setup with a
progressive characteristic for the whole travel
is recommended to get a comfortable suspension under all conditions of use. The elastomers support the steel spring from the
beginning. By changing the relation between
the number of elastomers and number of
spacers, you can influence the suspension
characteristic and the maximum force the
strut can bear before it bottoms out.
Examples in the diagram are the curves nr. 1
and nr. 2 which show the standard setups.
They feature moderate progression and increased maximum load compared to a single
76
A characteristic like this (3) can be achieved
by a steel spring which is responsible for taking all the load at first and will be supported
by only a few elastomers towards the end of
travel. (Example setup: empty-spacer-spacerelastomer-elastomer)
To exchange elastomers or spacers, the end
cap and the preload adjuster (which is under
tension) must be removed. Having done so,
the steel spring and the inside elastomers and
spacers can be taken out. The lower support
of this suspension package is an axial bearing
which consists of three parts. This bearing or
its parts may stick to the spring (caused by lubricant). Make sure this axial bearing is
mounted under the spring in the correct order (washer-bearing-washer) during reassembly. If there are elastomers left in the strut, a
thin needle pricked into will help to remove
them. Now the springs, elastomers, and spacers can be recombined. When screwing in the
preload adjuster disc, make sure it is aligned
straight. It must be screwed in against spring
force, therefore the assistance of a second
person might be asked.
Caution! The suspension must be
set up in a way that avoids permanent bottoming out (a clearly recognizable bumping
into the end stops). Permanent bottoming
out may reduce the components' life time.
To remove the stabilizer bar, simply unscrew
both bolts which connect the stabilizer bar
brackets to the frame plates. Now the stabilizer bar can be pulled out of its bushings in
the wishbones. The aluminium brackets can
be removed afterwards. Assembly is done in
reversed order.
Caution! Make sure that the axial
bearing was mounted correctly between
spring and support plate inside the strut
during assembly. A missing or wrongly
placed axial bearing may damage the suspension strut or lead to steering heaviness.
Caution! Before inserting the
countersunk bolts, make sure the brackets
are fitted planar to the frame plates and
the hole centres are aligned to each other.
Otherwise you may damage the threads
and destroy the brackets.
Stabilizer bar
To decrease body roll while cornering, the
axle is equipped with a stabilizer bar. As long
as the spring deflection height is the same on
both front wheels, the stabilizer bar has no effect. If one single wheel is moving upwards
(e.g. the outside wheel due to the dynamic
forces at high speed cornering), the stabilizer
bar works as a torsional spring and increases
the spring rate of this wheel. Besides, it
transmits parts of this wheel's load to the opposite wheel's suspension strut which then
supports the higher-loaded wheel. As a result
of this the single-sided suspension on bad
quality roads will be harder compared to both
wheels moving at the same time in the same
direction.
If you prefer a very comfortable ride, it is possible to mount the soft (white) stabilizer bar
in spite of high loads and appropriate spring
setup. However, the Scorpion fs will lean
more outwards in fast driven corners.
Removing and disassembling the suspension
struts
To provide a long lasting, faultless function of
the front suspension, the struts must be maintained regularly according to the service plan
on page 98. During design, great importance
was attached to keep the bearings of the front
suspension free from dirt and moisture. That's
why the struts are equipped with a shock
boot with vent holes situated inside the
frame's steering tubes. This makes sure that
predominantly clean and dry air is exchanged.
Depending on the area and conditions the tricycle is operated in and under, dirt and moisture could nevertheless reach the bearings
inside. Hence it is necessary, especially after
riding under rainy and snowy or off road conditions, to check the struts for dirt and clean
them. Under extreme conditions, we recommend to shorten the maintenance intervals
given in the service plan.
If you prefer a sporty style of riding with a
minimum of body roll, you may also use the
hard (grey) stabilizer bar with a soft spring
setup.

Handling instructions
Front suspension elements
Front suspension elements
Danger! While adjusting the
front suspension, never load the tricycle,
e.g. by resting on the seat or loading the
racks when your hands or tools are close
to the suspension struts. Your hands may
be bruised when the suspension compresses.
Caution! Use aging-resistant,
lithium soap based grease to lubricate.
Never use grease containing solid lubricants such as molybdenum disulfide or zinc
sulphide.
Caution! Never clean your tricycle and especially parts of the suspension
with a pressure washer or steam cleaner.
These devices remove lubricant and transport dirt into the bearings which causes
higher wear.
To clean the suspension strut occasionally,
clean the shock boot and slide it down completely. Clean the stanchion tube thoroughly
with a soft, dry cloth. Apply a thin layer of
grease or suitable oil. Finally, slide back the
shock boot to its original position.
To maintain the suspension strut according to
the service plan or to exchange the elastomer
bands for damping adjustment, it has to be
removed and disassembled. Therefore, fit the
tricycle to a work stand in a way that provides
easy access to the respective front wheel.
Remove the front wheel. Remove the brake
caliper according to the manufacturer's manual. Unfasten the fender (see page 82). Demount the stabilizer bar as described above.
78
Unscrew the outer rod end of the track rod
from the suspension strut. The lower collar of
the rubber cap must be slid upwards to access
the self-locking M6 nut.
Unscrew the hex bolt M6x40 A at the strut's
lower end, which connects the strut with the
wishbone.
Caution! Always secure the
wishbones or track rods by tying them to
the frame (e.g. using zip ties) to make sure
they won't move until their stop. This
would damage the spherical plain bearings
and rod ends.
Now remove the end cap B at the suspension
strut's upper end. Unscrew and remove the
clamp C as well as the spacer D, F, cap E and
spacer F below. Pivot the strut in a way that it
may pass the wishbone and push it downwards to slide it out of the elastomer bearing
G. In case the strut won't pass the wishbone,
you have to dismount the wishbone's rear
pivot point.
A hammer punch on the bolt releases the piston inside
the knuckle.
Remove the hex bolt A and slide the stanchion tube 3 (golden) out of the knuckle.
Exploded view of the suspension strut assembly
Slide off the washer H at the suspension
strut's upper end. For further disassembly, cut
the zip tie at the bottom of the shock boot 1
and slide the shock boot off the strut. Now
screw in hex bolt A, on the underside of the
strut for approximately 4mm. Grab the suspension strut firmly at the knuckle (lower
black part) and beat the screw head with a
rubber hammer to release the piston 6 inside.
The elastomer band 8 can now be removed.
Clean the sliding surfaces of the stanchion
tube and the bushings 4, as well as the inside
of the knuckle 2. Use a clean soft cloth. If
there is noticeable play in the bushings or if
the bushings are damaged, please contact your
dealer. Lubricate the surfaces of the clean
bushings 4. Check the proper position of the
bottom out elastomer 5 inside the knuckle.
Apply a thin layer of grease on the stanchion
tube 3.

HP VELOTECHNIK for best performance.
You can also use aging-resistant, lithium
soap based grease to lubricate. Never use
grease containing solid lubricants such as
molybdenum disulfide or zinc sulphide.
Insert the elastomer band without wrinkles in
the knuckle between the two bushings. Slide
the stanchion tube back into the knuckle. Slide
on the shock boot and insert its upper end
into the stanchion tube's groove. Apply a new
zip tie to its lower end. Slide on the washer
H. Press the suspension strut into the elastomer bearing in the frame. Assemble spacer
F, cap E, spacer D, clamp C, and end cap B.
Fix the suspension strut in its elastomer bearing by tightening the end cap with 1-2 Nm and
fasten the clamp.
Connect the suspension strut with the spherical plain bearing in the wishbone by the
M6x40 hex bolt (part order: strut - thin sealing ring I - pivoting bearing J - spacer 6mm
long K with thick sealing ring L - screw head
A). Tighten the screw with a torque of 9-10
Nm. By doing this, the piston is locked at the
lower end of the suspension strut in its correct position.

Exploded view of the suspension strut interior
Caution! Use thread locker (e.g.
Loctite 243) with all bolted connections
that are not equipped with self-locking
nuts, else the connections may become
loose.
When mounting the rod end at the suspension strut, take care to assemble the parts in
the correct order, from upside: screw head,
steering lever, washer 6, spacer 6 mm length,
rod end, self-locking nut M6. In case you have
removed the rubber cap, circlip pliers will
help you to reassemble.
Swing arm pivot
The rear swing arm pivot comes with maintenance free bushings. They feature a self lubricating system with Teflon particles. The
bushings sustain a very high load and they
show almost no wear.
In case you notice play or a creaking noise at
the rear swing arm please check the two
screws that keep the axle in the frame. They
have to be secured with thread locker.
In case the rear swing arm is to be dismounted completely you can prevent the axle
from turning by inserting a thin metal rod in
the hole of the axle through the hole in the
rear swing arm under the axle.
Caution! There has to be a big
washer between the main frame and the
end of the bushing else the bushing is not
able to function without play and the frame
will be damaged.
Tightening torque: 17-19 Nm
(Please follow the tightening torque settings
listed in the table on page 88.)
Danger! If the screws at the axle
are not tight enough this leads to play and
noises when the spring compresses. In extreme cases the swing arm may come
loose which leads to a serious fall. If the
screws are too tight the thread of the axle
may tear out or the screw may be damaged.
The bushings are exchangeable. For that purpose you will have to dismount the rear swing
arm and send it together with the axle via
your specialist dealer to HP VELOTECHNIK. After installation the bushings are machined to
adjust them.
Unscrewing the axle bolts
Before being able to unscrew the axle bolts a
possible rear rack must be disassembled. To
do so both lower screws of the rear rack
must be unscrewed completely, both upper
screws must be loosened. Then, the rear rack
can be swivelled upwards.
You can prevent the axle from turning by inserting a
thin metal rod in the hole of the axle.

Mudguards
Mudguards are exposed to very strong vibrations, especially at suspended wheels, which
may cause them to break. Please check the
stays and mountings of the mudguards regularly for their position and check the mudguards themselves for cracks or deformations.
Replace damaged mudguards immediately.
Front mudguards
If the wheels are removed, the tricycle must
not rest on the front mudguards. Loosen the
screw between mudguard mounting and
knuckle to remove the mudguard.
The front mudguards are adjustable in height
to accommodate different tire heights by
means of the slotted holes in the mudguard
mounting.
After having performed service work or after
replacing mudguards check if the wheels turn
freely. There has to be a distance of at least 7
mm between mudguard and wheel.
Check whether the suspension can still be
completely compressed with mounted mudguards. The mudguards, stays, mountings, and
screws must not touch other parts under
maximum compression.
Caution! You must not mount
additional parts like rear lights or reflectors to the mudguards since those may
break then

Danger! If branches or other
obstacles get caught in the wheels while
riding and are moved around they may
drag the mudguards along. The mudguard
can possibly fold up between frame and
tire and hence block the wheel, which may
lead to a serious fall. If you hear any unknown noises while riding stop immediately and remove anything that might cling
to the mudguards or the wheels.

Danger! Make sure that the
sheet metals are fastened with the correct
tightening torque (7–9 Nm) and the screws
are secured with retaining washers and
thread locker. Frequently check the assembly. If a sheet metal becomes loose, the
fender may be caught by the wheels and
lock the wheel or flung away. This may
lead to serious injury or fall!

Maintenance and care
Maintenance routine
However, you will have to maintain your bicycle regularly, as it is with other vehicles too.
At least once a year the bicycle has to be
taken to a bicycle mechanic for an overall service. Only this way a long lasting and safe
function of all parts of your bicycle can be
guaranteed. It maintains the value of your bicycle as well as the fun and the safety while
riding for many years.
Read in this chapter how to perform smaller
maintenance and care works between the
services.
For a quick overview of the works to be done
take a look at the Warranty Pass on page 91.
Caution! The maintenance
works on this recumbent partly require
special tools and skills. Do only work
within your limits and, in the interests of
your own safety, do not go beyond. Should
you be uncertain at any point, get in contact with your local dealer.
Cleaning and conservation
The frame of the Scorpion fs 26 has a high
quality and environmentally friendly powder
coating. The surfaces of the aluminium parts
are either polished or anodised. Threads and
technical contact areas can be unfinished and
must be protected with wax.
To keep the surfaces brilliant over many years
and to protect them effectively against corrosion the bicycle has to be cleaned from dirt
and then conserved.
Dried sweat but also environmental influences
such as air pollution, dirt on the roads and especially grit affects the parts, and not only may
this cause flaws but also serious structural
damage of the parts by corrosion.
In contrast to a widespread belief particularly
the "non-rusting" aluminium is dramatically affected by grit! This kind of damage may not be
visible in the beginning but it leads to a serious
danger when the part breaks. Clean and conserve your bicycle diligently!
The best things to clean your bicycle with are
warm water and a soft cloth. If your bicycle is
very dirty first take a wet sponge to soften
the dirt and then remove it. In case of bad
grease or oil stains you should use a special
cleansing agent for bicycles in addition.
Wear and Tear
As on many other vehicles, some parts on a
bicycle are affected by wear and tear. The lifetime expectation of these parts depends on
the intensity and type of use as well as on the
maintenance and care. Please keep in mind
that the process of wear and tear is normal
and no reason for a warranty claim against
your dealer or HP VELOTECHNIK.
Caution! Do not use any cleansing agents that scrub or are chemically aggressive since they affect the paintwork.
Before using any cleansing agent please test
it at a part of your bicycle that is not immediately visible.
You will find more specific information on
wear and tear in the chapters on the relevant
parts.
85
Maintenance and care
Your tricycle is equipped with the latest bicycle technology that does not require much
maintenance.
Maintenance routine
Caution! Do not use any highpressure cleaner. The strong jet of water
goes through the seals of the bearings,
blows away the lube and causes corrosion
of the bearing parts and the chain. In addition to this it may damage stickers.
While cleaning your bicycle check it for any
cracks, scratches, deformations, damaged
parts, loose spokes etc. If you are in doubt
please consult your local bike shop.
Caution! Any damage of the
paintwork has to be cleaned from rust and
repaired immediately, else the damaged
part in the frame gives way to corrosion
that nests in the surrounding paintwork.
This can result in damage of the frame.
Caution! Take care that after
folding the tricycle there are no parts rubbing against the frame. This may damage
the paintwork.
In case of small scratches at the surface of the
powder coating of the frame or the surface of
the seat you can simply polish them away. You
can buy a special polishing agent for epoxy
resins at a specialist dealer for boat building.
Do not use a polish for metal!
After cleaning the tricycle, dry it and treat the
paintwork and the metal surfaces with wax.
You can purchase this wax from your local
bike dealer as a convenient spray.
86
The wax passes moisture and flows into tiny
gaps and pores. After some minutes the solvent evaporates and leaves a dull and glutinous film. Now polish the waxed parts of
your bicycle with a soft cloth to make it real
shiny.
Do not only wax the frame but also the
spokes, hubs, screws and nuts etc. You can
also conserve the chain with wax spray after
lubricating it, see also the chapter on "Chain",
page 51.
The frame has small holes for ventilation that
prevent condensation in the frame. These
holes must not be sealed. However, moisture
may enter the frame through the holes.
Therefore protect the inside of your frame by
applying wax spray through the holes.
Protect the parts where cables or chain tubes
may scratch the frame. You can buy special
stickers at your bike dealer or extra strong
transparent tape at your do-it-yourself-store.
That way you avoid scratches in the powder
coating and coating coming off.
Maintenance routine
Storing the bicycle
Before storing your bicycle over a longer period of time, e.g. during winter, please take
care of the following steps:
Maintenance and care
x Clean your bicycle and protect it from corrosion as described in the chapter on
"Cleaning".
x Store your bicycle in a dry and warm place.
Avoid direct sun and storage close to the
heating since it affects the rubber of your
tires.
x Choose the smallest sprocket and the
smallest chain ring. That way the cables are
in the most relaxed position.
x The tubes of your tires loose air when
standing over a longer period of time. If the
bicycle then rests on flat tires the tires may
be damaged. Therefore hang up your bicycle
or check the air pressure regularly.
The winter months are a convenient period of
time for the annual service since then you
won't have to wait long for an appointment.
Many dealers offer special prices for the winter check.
Transport in the car
The best way to transport your tricycle is inside the car. Take care that it does not lie on
the derailleur.
If you want to transport it outside the car we
recommend a roof-rack or a rear carrier.
Take care to fasten your tricycle at the frame
only.
Please remove any parts that could come
loose during transport (seat cushion, water
bottles, luggage bags, pumps, pennants, etc.).

Warranty
Warranty policy
Your authorised dealer has to fully set up and
adjust your bicycle, so that safe function is
guaranteed. The dealer has to make a final
safety check and carry out a test ride.
Your cycle dealer is obliged by law to ensure,
among other things, that your bicycle is not
affected by defects which materially diminish
its value of suitability for the described purpose. The exact details will vary according to
the country. In Germany, this liability ends
two years after purchase.
In addition to this HP VELOTECHNIK offers a 10
year warranty on the frame against damage
through material or manufacturing defects.
This warranty applies only to the original purchaser.
Damage caused by wear and tear, corrosion
or damage at the surface coating is excluded.
Damage caused by inappropriate use, inadequate care and maintenance, falls, crashes,
overloading through excess weight, incorrect
assembly or modifications to the tricycle is
also not covered. The onus rests with the
purchaser. The warranty is void if any of the
instructions in this manual are neglected.
Warranty is only valid for original parts from
HP VELOTECHNIK. In case of warranty we will
replace or repair the damaged part with a
part of our choice or a new part equal to the
old one (warranty obligation). We do not
cover any transport, labour or any secondary
costs.
The warranty is void when using the bicycle
for commercial purpose such as rental or
leasing
The warranty starts with the date of purchase
(receipt of the tricycle dealer) of a new bicycle. The warranty is processed via the tricycle
dealer who ordered the bicycle from us.
90
In case of damage the dealer has to send the
damaged frame to us so that we can check it,
if asked to do so by us.
In the event of any action that falls under warranty the original warranty period will not be
prolonged and no new warranty will be given.
If HP VELOTECHNIK refuses to count a repair
as warranty case we will only carry out a repair with costs after having talked to the customer or his representative, the respective
dealer.
It is necessary for the purchaser to fill in the
enclosed warranty registration form to benefit
from the extended warranty. This filled in
form has to be sent to HP VELOTECHNIK
within 4 weeks after the purchase.
The warranty is only valid when the warranty
pass at the end of this manual has been filled
in when you received your tricycle and when
every inspection listed has been done and recorded by your bicycle mechanic within the
described time schedule.
In the event of any warranty the warranty
pass together with a copy of the proof of purchase has to be sent to HP VELOTECHNIK
through your dealer.
This warranty does not have any influence on
the rights of the purchaser according to his
statutory rights.

name:
With the HP VELOTECHNIK Warranty Pass you
can assure the safety and proper function of
your tricycle for many years.
Like any other vehicle your tricycle has to be
checked for safe operation before riding. Your
bicycle has to be maintained at regular intervals, at least once a year you will have to take
your tricycle to a qualified bicycle mechanic
for a thorough check.
address:
The service plan on the next page shows you
our mandatory maintenance and service
works.
You can avoid seasonal waiting periods in
spring and summer when you have your annual inspection done in the quiet months from
October to January. Many bike shops then
have special winter check offers. At any rate
do make an appointment. Clean your bicycle
prior to the inspection since then many of the
checks by sight can be done quickly and at low
cost.
Please have your specialist dealer record
every inspection and service work in the
Warranty Pass. This is a requirement for the
validity of our extended warranty that exceeds the legal warranty.

I have received the bicycle in good condition,
adjusted to my size and performed a test ride.
I have been informed about the correct use of
the recumbent, the components like derailleur
and especially steering and brakes as well as
the necessity of regular service and maintenance. I will read the manuals prior to the first
ride and have all future users read them too. I
am aware that I need to send the warranty
registration form to HP VELOTECHNIK within
four weeks of the purchase to qualify for the
extended warranty.
