QUICK START GUIDE FOR
STROMER
1) Completely charge the battery before
the first ride, internally or externally.
a) External charging:
These are brief operating instructions intended for experienced S-pedelec riders. You must
read the entire original operating instructions to
ensure safe riding, even when you already have
experience with S-pedelecs!
Removing the battery
Detailed supplementary information regarding the functions and settings are provided by the Stromer app or on the Internet at
www.stromerbike.com/support
Charge battery externally
Only charge the Stromer battery with a
Stromer charger.
Inserting the battery
6 7
The Stromer can obviously also be used like
a normal bicycle without a motor.
2) Switch on the electrical system
The power button is located at the bottom of the
top tube, below the touch screen.
The motor support depends on the force that acts
on the pedals. The more firmly you step onto the
pedals, the stronger the support from the motor.
The motor support stops when you stop pushing
the pedals during the ride. Motor support is only
reactivated when you start working the pedals.
The writing “THIS SIDE UP” must be visible
on the top.
b) Charge battery internally
The motor of the Stromer only starts up
once a minimum speed has been reached to ensure your safety. Always keep one brake engaged
before placing the first foot onto the pedal. The
strong acceleration feels very unfamiliar. Uncontrolled starting up in road traffic or on loose
ground can lead to a fall or severe injuries. Practice operating and riding your Stromer in a quiet
and safe place before you take to public roads!
The boost mode is activated when the plus
button on the operating element is pressed and
held for two seconds! The Stromer will then accelerate without pedal support to a speed of
20 km/h! This boost mode only kicks in at a driving speed above 0.5 km/h.
Operating element
Important functions of the Stromer can be controlled while riding and without taking your hands
off the handlebar, by using the operating element
on the handlebar.
Switch on the
light/main light
Never ride when the battery is not inserted.

FOR YOUR SAFETY
Before riding your pedelec on public roads, you
should inform yourself about the applicable national regulations in your specific country.
In many countries you will require a driving license for driving an S-pedelec. Check the legal
situation in the respective country before use.
The operating instructions assume that you can
ride a bicycle. These instructions are not intended
to teach you how to ride an S-pedelec. They are
also not intended to provide information regard-
8 9
ing the assembly or repair of an S-pedelec or how
to assemble and repair your Stromer.
Remain aware that riding an S-pedelec is generally and always associated with risks. You, the
rider, are particularly at risk. Always remain aware
that you are not as protected as you would be, for
example, in a car. You have no airbag and no protective car body. You are nevertheless faster and
drive on other parts of the road than pedestrians
or many cyclists, who do not have a sufficiently
strong auxiliary drive. Pay particular attention to
others on the road.
The following information regarding the rider
must also be considered:
• Always wear a fitted and suitable S-pedelec helmet. Use it
each time you ride!
• Read the instructions of the helmet manufacturer to learn about
fitting the helmet correctly.
• Whenever you ride, wear bright clothing or
sports clothes with reflective elements (e.g. reflective vest); This is important to ensure that
you are seen in time by other traffic participants.
• Tight clothes and trouser clips are mandatory
to wear. Your shoes should have an anti-skid,
stiff sole.
• Never ride hands-free!
• Never ride with headphones. Never talk on the
phone while riding your S-pedelec. Never ride
your bike if you are not in a situation where you
are completely able to control it. You must always be fully fit to ride.
• Under wet and slippery conditions, alter your
way of riding accordingly. In this case, you
should ride more slowly and apply your brakes
earlier and more gradually as the braking distance becomes significantly longer.
• Ride at an appropriate speed and in accordance
with the terrain and your riding capabilities.
Take note that you are exposed to special risks when
participating in traffic on an S-pedelec. Protect yourself and others by riding responsibly and safely!
Take note that you will be riding much faster on an S-pedelec than on a bicycle without an
electrical drive. Other traffic participants might
misjudge that. Only use your S-pedelec in an appropriate manner. Important, relevant information is provided in the “Appropriate use” section.
Ask your Stromer dealer if you are not sure about
the purpose of use and the limits of the appropriate use of an S-pedelec.
You can find information about the bike’s operation, maintenance, upkeep and technical data
in this Instruction Manual, under
www.stromerbike.com/support and on each of
the component manufacturer’s websites.
The electrical installation of your S-pedelec
is very powerful. Correct and safe operation requires you to have your Stromer regularly maintained by a Stromer dealer. Have your S-pedelec
regularly maintained by a Stromer dealer. They
will check the current software status and ensure
that important updates that affect the safety and
riding comfort are installed.
Immediately switch off the electrical system and
remove the battery when you notice damage to
the electrical system or, for example, when live
parts are exposed after a fall or accident.
Always contact your Stromer dealer when you require repairs, want to ask a question, experience
problems or discover a defect. A lack of technical
knowledge can lead to severe accidents or damage!
Always turn off the electrical system and
remove the battery before doing any kind of work
on your S-pedelec. Ensure that the charger is not
connected.
If your Stromer S-pedelec does not start, although no error message is shown, check whether
both brake levers are in their initial position! No
motor power is transmitted when one of the brake
levers is activated!
an energy source for powering the head light and
the tail light. The lighting system of the Stromer
is powered by the battery or, when this has been
drained, by a motor with dynamo function.
Stromer S-pedelecs are provided with lights based
on the latest LED technology.
LIGHTING SYSTEM
When the daytime running light is activated, it is
on whenever the Stromer is switched on. (See daytime running light www.stromerbike.com/com/
support). The daytime running light is dimmed
when the headlight is switched on, so that drivers
in oncoming vehicles are not blinded.
The daytime running light is not legal in certain
countries and can accordingly not be activated
there. Please stay informed regarding the legal
situation!
It is not possible to replace the bulbs in
modern LED lights. Clean your reflectors and
lights on a regular basis. Warm water with cleaning fluid or washing up liquid is suitable here.
It is recommended to adjust the headlight pointing downwards so that the center of the light cone
emitted drops to half its height between the headlight and a point at a distance of 5 m. The law in
Germany prescribes this setting.
We recommend activating the daytime running light at all times, as far as this is permitted
in the respective country. You can then more
easily be seen by other traffic participants and
thus increase road traffic safety.
A working lighting system is essential for
your safety! Have the installation, inspection and
repair performed by a Stromer dealer.
S-pedelecs used on public roads have to be
equipped with a generator, a battery providing a
nominal voltage of 6 V (permanent battery lighting) or a rechargeable energy storage device as
Changes to the lighting system are not permitted
and may lead to a loss of warranty, guarantee and
insurance cover!

INSTRUCTIONS ABOUT ELECTRICS AND ELECTRONICS
CHILD SEATS, CHILD TRAILERS AND LOAD TRAILERS
Stromer S-pedelecs may not be operated
with child seats!
Do not let children who are unattended ride
the S-pedelec without first thoroughly instructing
them in how to use it! Explain to children the dangers of using electrical devices.
If a child wants to ride the S-pedelec, check
whether the child has reached the prescribed
age and has the appropriate driving permit as required!
Always check the applicable national regulations before using child trailers and load trailers.
These may also concern the permitted maximum
speed and the permitted total weight! The use of
child trailers in combination with S-pedelecs is
prohibited in many countries.
Trailer
For operation with trailers, please research
the applicable regulations in your country.
Only use your Stromer with trailers that have explicitly been released for use with S-pedelecs. Take
note that many countries prohibit the transport of
children in a trailer attached to an S-pedelec.
10 11
Please take note that the driving characteristics
of the Stromer change when attaching a trailer.
Some trailers tend to tilt in tight bends. Drive
carefully and adapt your speed and riding style
to the situation.
Some trailers are only approved by their manufacturers for use with bicycles or pedelecs (peddling
support up to 25 km/h). It is essential to adhere
to the instructions of the respective manufacturer.
Legal situation in Switzerland
Transporting a trailer is permitted under certain circumstances as long as certain restrictions are adhered to (Swiss federal road traffic regulations (VRV)
Art. 68 para. 1 in connection with Art. 68 para. 7).
At most two children in protected seats may be
transported in one trailer (VRV Art. 63 para. 3 Letter d).
On fast S-Pedelecs with assisted pedaling of more
than 25 km/h, the carrying of children in a trailer
is permitted. A child seat and a child trailer must
not be operated at the same time. (VRV [German
federal road traffic regulations] Art. 63 para. 3 lett.
d. VrV)
It is permitted to transport a child on a trailing
unit (according to VTS [Swiss technical requirements for road vehicles] Art. 210 para. 5) such as
the one made by FollowMe, when the child can
use the pedals while sitting (VRV Art. 63 para. 3
Letter b).
Children being transported are not obliged to wear
a helmet in Switzerland. However, we recommend
that children in the trailer always wear a helmet
and to buckle them in with the trailer’s internal
safety belt system.
Please check the legal requirements of your
country.
Installation
Have the trailer and its attachment mounted
by a Stromer dealer.
The installation of the following trailer connection
systems was tested by Stromer.
• Thule ezHitch, Webber-E and Burley couplings
can be mounted on the optional Stromer Trailer
Plate Kit (Art. 221019). Check other coupling
systems before you buy.
• Various manufacturers offer optional fullaxle couplings/adapters with the dimensions
M10x1. These couplings make it possible to
mount, for example, a BobYak or a FollowMe
to the Stromer Trailer Plate Kit (Art. 221019).
Get advice from a Stromer dealer on the operation
of the trailer.
Instructions for parents and
guardians
As a legal guardian, you are responsible for
watching over the child and his or her safety. This
includes taking care of the S-pedelec’s technical
state and supervising the rider.
You must be sure that the child has learned safe
handling of the S-pedelec and fulfills all legal and
country-specific requirements, e.g. has reached a
possibly prescribed minimum age and has the appropriate driving license as required.
Do not let children who are unattended ride
the S-pedelec without first thoroughly instructing
them in how to use it! Explain to children the dangers of using electrical devices.
BEFORE THE FIRST RIDE
• Adjust the seat to a safe and comfortable position for you (see page 48).
• Allow your Stromer dealer to set up the brakes so
that the brake levers are always within easy reach.
• Ensure that you know which lever operates
which brake.
Familiarize yourself with the new bicycle in
a protected area.
Please thoroughly read all of the warnings and
instructions in this operating manual before you
begin riding the S-pedelec.
Please also consider the operating instructions of
the individual component manufacturer, which
are available on the Internet.
Modern braking systems can have significantly stronger and different braking effects to the
brakes you are familiar with. Please get to know
the brakes on a safe piece of land before setting
off on your first ride with the bicycle!
Also remember that the effectiveness of brakes
can be dangerously different in wet conditions or
on slippery surfaces. Please take the possibility
of longer braking distances and slippery surfaces
into account when riding!
Your specialist Stromer dealer will be happy to answer any further questions you have after reading
this manual. Ensure that the S pedelec is ready for
use and adjusted to fit your body. This includes:
• Setting the position and fixture of the seat and
handlebars
• Checking the assembly and settings of the
brakes
• Securing the wheels into the frame and forks
To ensure that you enjoy a safe and comfortable
riding position, please allow your Stromer dealer
to set up your handlebars and stem.
If rubber or plastic pedal covers have been
put on your pedelec, familiarize yourself with
their grip. When wet, rubber and plastic pedals
are very slippery!
Ensure that the wheels are securely fastened in
the frame and fork. Check the firm attachment of
the quick-release axles and all important fastening screws and nuts (see section “Screw connections”).
If you hear rattling or other unusual noises during
operation, have your Stromer dealer determine the
cause and remove it before you continue riding.
Push the S-pedelec forwards while pulling the
brake lever. The back brake should completely prevent the back wheel from moving, while the front
brake should lift the back wheel off the ground with
its braking effect. The bicycle’s steering should not
rattle while braking or exhibit any play.
Please take an initial test ride in a safe place
where you can familiarize yourself with the new
brakes! Modern brakes have a very strong braking effect.
Check the air pressure in the tires. You will find
instructions as to the correct tire pressures on the
sides of the tires. Please adhere to the required
minimum and maximum pressure!
If you cannot find any recommended pressures,
2.5 bar is a suitable pressure for most tires.
Hint: As a general rule of thumb when you are
out on a ride, you can check the tire pressure by
doing the following: If you place your thumb on
a pumped up tire, you should not be able to significantly change its shape by applying pressure.
Check the tires and rims. Scan them for any damage, cracks or deformations, as well as embedded
particles, e.g. shards of glass or sharp stones.
If you should find any cuts, rips or holes, please
refrain from riding! First have your S-pedelec
checked by a specialist.
ENGLISH
Ensure that your child has learned and understood
safe and responsible handling of their S-pedelec
in the appropriate environment.
It is also necessary for you to check the following
components of your S-pedelec:
• Check that the battery box is safely closed with
the battery inside.
• Check the charging state of the battery to ensure that the charge is sufficient for the drive
planned.
• Familiarize yourself with the functions of the
operating element.
Direction
Possible positions for adjusting bolted connections.
Always squeeze the brakes of your pedelec
before you place a foot on the pedal! The motor
starts propelling as you step on the pedal. This
boost is unusual and can lead to falls or cause
dangerous traffic accidents.
Positions of screw connections for adjusting the sitting position
Setting up the position of the handlebars/
stem
Consider that not every stem is suitable for
every steer tube when retrofitting your pedelec!
Only use Stromer stems. Only allow Stromer dealers to work on your handlebars and stem!
12 13
Installing pedals
If your pedelec was supplied without the pedals
pre-installed, these have to be attached with the
correct wrench. Please note that the pedals have
to be screwed on in different directions and secured with a high mounting torque (see page 68).
Apply assembly grease to both threads.
Ensure that you have read the manufacturer’s instructions before using step-in or clipless
pedals.
Practice clipping your shoes in and out of the pedals’ locking system before your first ride in a quiet,
safe place. Clipless pedals which do not properly
release are a safety hazard.
In the case of step-in pedals, you are able to
adjust how much force is required to release the
shoe from the pedal. Please test this on your first
ride with a setting that releases easily! Regularly
clean your step-in pedals and keep them in good
condition with a suitable spray lubricant.
Setting up the seating position
Before you use your Stromer S-pedelec for the first
time, the seating position has to be set up to suit
your body size. This is vital for riding safely and
securely.
To do this, the seat’s height, alignment and angle
have to be set up, as do the height and alignment
of the handlebars with the stem.
Knee angle 90°
BEFORE EACH RIDE
When adjusting the height of the seat, never pull the seat post further out than the maximum extension length marked! If your tube does
not have a maximum marking, then you must
leave a minimum insertion length of 7.5 cm.
Setting up the angle of the seat
Once you have set the height of the seat, you have
to check that the angle of the seat is suitable. In
general, the upper surface of the seat should be
horizontal. You can adjust this by loosening the
clamping bolts in the seat post.
Before every ride, please check:
• That the bell/hooter, all electrical plug-in connectors and lighting function correctly and are
safely attached
• That the brakes are working safely and are
properly secured
• That the battery box is safely closed with the
battery inside.
• The tightness of the pipes and connections
• Tires and rims for damage, eccentricity and
penetrating alien objects, particularly after
rides off fortified roads
• That the tires have a sufficient tread depth
• That the suspension components are working
properly and are safely secured
• The firm attachment of screws and nuts of quickrelease axles (see “Screw connections” section),
even when the vehicle was only unsupervised
for a short time.
• That the frame and forks are not misshapen or
damaged
• That the handlebars, stem, seat post and seat
are both correctly and securely fastened as well
as set up in the right position
Do not ride off when you are not completely
sure that your S-pedelec is in flawless condition.
Have it inspected by a Stromer dealer.
It is particularly important if you use your
S-pedelec a lot, either for sport or daily use, that
you regularly have all the important parts checked
by a Stromer dealer.
Frame and forks, suspension components and
other parts relevant to your safety such as brakes
and wheels are subject to heavy wear, which can
impact on the operating safety of these parts.
Components might spontaneously fail when the
predetermined usage period or service life is exceeded. This can lead to falls and serious injury!
Please make these checks before continuing
after a fall or if your S-pedelec falls over! Aluminum parts cannot be safely bent back into shape,
while carbon components can sustain damage
which is not recognizable to the eye!
If you have fallen
Check the whole of th S-pedelec for changes. These
may be dents and cracks in the frame and the fork,
but also bent components. You must also check the
function and safe attachment of parts that have been
shifted or twisted, e.g. the handlebars or the seat.
ENGLISH
• That the seat post and seat are secure. Try
turning the seat or tipping it upwards or downwards. It should not move.
• When you are riding with clipless/step-in pedals: Functional testing is required. The pedals
must release easily and without problems.
If you notice any changes to your S-pedelec, DO
NOT continue cycling. Do not re-tighten any loose
parts without first checking them and always use
a torque wrench.
Bring your S-pedelec to a Stromer dealer, describe
the fall and get your S-pedelec inspected!
is not constructed for this use. Overloading of the
seat post with a luggage rack may break the seat
post and lead to serious accidents.
The permitted total weight of the vehicle may not
be exceeded, even when a luggage rack with a
higher carrying capacity would enable that!
LUGGAGE AND LOAD
TRANSPORT
Front-wheel luggage carriers
Front-wheel luggage carriers may not be installed
or operated.
Attached accessories must always be installed according to the regulations and instructions. You must ensure the correct fastening
torques for all screw connections (see “Screw connections” on page 68)
• Only use add-on parts that comply with the
respective legal regulations and road traffic
regulations.
• The use of unlicensed parts may lead to accidents.
You should therefore only use original accessories and add-on parts which fit your S-pedelec.
• Use the advice of a Stromer dealer.
Safety information for luggage transport
Luggage loads change the behavior of your
S-pedelec. They extend the braking distance, among
other things. This may lead to severe accidents or
falls. Adapt your riding style to different driving
characteristics, i.e. brake earlier and consider the
more sluggish steering properties. Only transport
luggage on the luggage rack intended for this purpose! Child seats may not be installed or operated.
Please ensure that nothing can get caught in the
spokes and turning wheels.
Rack
Only retrofit luggage racks to S-pedelecs
that have been approved by Stromer for this purpose. Use only the intended fixing devices.
Ask your Stromer dealer whether and how luggage may be transported when using add-on parts
made of carbon. Don’t fix racks to the seat post! It
14 15
If you are riding with luggage, ensure that
you do not exceed the maximum permissible
weight of the S-pedelec. Information on the
weight capacity of the rack is also stated here.
Additional information regarding this issue is provided at www.stromerbike.com/support
LEGAL REQUIREMENTS
The regulations and requirements for e-bikes
are continuously being revised and may change
at any time. Obtain information regarding the
valid legal requirements so that you are always up
to date.
For S-pedelecs, special provisions apply for their
limit of use. This means that e-bikes are sometimes
operated like a bicycle and at other times not.
Before riding on public roads with your Stromer,
inform yourself about the current legal requirements enforced in your country.
This information can be found at your Stromer
dealer, the respective national bike or e-bike associations and online.
There you can obtain information on how your
Stromer must be equipped in order to drive in
traffic on public roads. These sources describe,
for example, which lighting systems have to be
installed and which brakes the S-pedelec must
have.
The currently valid, national regulations also deal
with age restrictions and specify from which age
people are allowed to drive on which part of the
road and whether certain driving permits are required. The regulations for children riding on public roads are also found here. It will be made clear
if a helmet is required to be worn by law.
Check whether your private third-party-liability insurance covers possible damage caused
by using a Stromer S-pedelec.
APPROPRIATE USE
The total weight of the Stromer S-Pedelec is
140 kg. Permitted total weight: Weight of driver +
weight of S-pedelec, including weight of battery +
weight of luggage + weight of trailer (if trailer is
permitted).
Use as intended also includes adherence to the
operating, servicing and maintenance conditions
that are described in this manual.
Stromer S-pedelecs may be used on public roads
and fortified paths when they are equipped as prescribed by national law.
Manufacturers and dealers are not liable for damages resulting from use outside of intended use.
This applies particularly to damages resulting
from non-adherence to the safety instructions,
e.g., in terms of:
• Use on terrain
• Overloading, or
• The incorrect remedying of defects
Stromer S-pedelecs have not been designed for
extreme loads, e.g. driving over stairs, rider tricks
or jumps.
REPLACING PARTS ON YOUR
SPEED PEDELEC
Specific components are defined in the approvals
process which are allowed to be used on this vehicle. In other words, the S-pedelec is only permitted if your vehicle uses these parts or replacement

ENGLISH
S-pedelecs are means of transport designed
to be ridden by one person. It is not permitted to
transport children in trailers of S-pedelecs within
the scope of validity of EU law!
Transporting an additional person by using an
S-pedelec, e.g. in a child trailer, can only be permitted within the framework of the respective,
national law. We urgently advise against transporting additional persons, even in specific cases
where this might be permitted.
If you would like to transport luggage, this requires that your S-pedelec is fitted with suitable
equipment. Children may not be transported by
S-pedelecs within the scope of EU law and they
may only be transported in trailers dedicated for
this purpose in Switzerland. We recommend not
taking any chances when it comes to quality in
this area! Please take note of the permitted total
weight and the stipulated maximum speed for the
trailer.
Use original parts or replacement parts for which
an expert opinion regarding the approval for your
S-pedelec exists, or obtain an individual permit

OPERATING ELEMENT
Important functions of the Stromer can be controlled while riding and without taking your hands
off the handlebar, by using the operating element
on the handlebar.
Switching on
Lighting system
A daytime running light is integrated into your
Stromer to increase safety in daily traffic.
Light button
Press the power button to switch on.
Plus button
When your Stromer has been locked with a
PIN, you must unlock your Stromer after switching it on before you can use it. (See “Theft protection” chapter)
Minus button
Switching off
Support levels
1. Press the Power button to get to the shortcut
display.
2. Select OFF.
The + and – buttons of the operating element
on the handlebar make it possible to change between the following support modes:
Bicycle mode: The motor is switched off.
Support mode 1: Low motor support, optimized
for large driving range.
Support mode 2: Medium motor support – this
support mode can be fine-tuned by using the
Stromer app.
Support mode 3: High motor support for maximum speed.
Sleep mode
When the Stromer is not switched off, it will
switch to sleep mode after approx. 5 minutes of
inactivity. The sensor system remains active during sleep mode. The system wakes up by itself as
soon as you move the Stromer.
Alternatively, you can also wake up your Stromer
by using the power button.
Always switch off your Stromer by using the
touch screen when you want to prevent it from
switching itself on.
16 17
The motor support depends on the force that acts
on the pedals. The more firmly you step onto the
pedals, the stronger the support from the motor.
The motor support stops when you stop pushing
the pedals during the ride. Motor support is only
reactivated when you start working the pedals.
Press the light button on the operating element
on the handlebar to switch the headlight on or off.
In some countries, the daytime running light can
not be turned off.
When you are traveling and your battery is
drained, the motor of the Stromer assumes the
function of a dynamo. This ensures that enough
electricity is produced to power the lighting. Thus
you can always ride safely with your Stromer.
Braking mode / Recuperation
Stromer S-pedelecs can also generate energy with
their motor and thus charge the battery, for example, when driving downhill. In this case the
motor acts like a dynamo, i.e. it performs a braking function and thus generates the power that
charges the battery. This may significantly extend
the driving range for a tour. Recuperation can further be used as a convenient “engine brake” on
steep or long declines.
As soon as you brake, the motor switches to recuperation/brake mode and supports your braking effort.
Boost mode / Driving speed
switch
sure on the touch screen is sufficient to navigate
through various menus or change to the riding
display.
Riding display
The touchscreen changes to the driving display as
soon as you start riding your Stromer.
As soon as you release the plus-key, the boost
mode will be deactivated.
ENGLISH
The braking energy is stored in your battery and
therefore increases the driving range of your
Stromer.
The Stromer offers a braking aid for prolonged
downhill drives. To use this, keep the minusbutton pressed for 2 seconds. The braking force of
your Stromer can now be adjusted by again pressing the plus or minus button.
To terminate recuperation, again keep the + or –
button pressed for another 2 seconds.
A weak recuperation level brakes less and is
therefore suitable for flat declines, while strong
recuperation levels brake significantly more. The
range is therefore easily and conveniently optimized.
The recuperation is automatically terminated
when the speed falls below a certain minimum
and you step onto the pedals. This speed varies
according to the version of the firmware loaded. It
is usually below 10 km/h.
The boost mode only switches on when you
exceed a minimum speed. As soon as you release
the plus button or activate the brake, the boost
mode is switched off.
TOUCHSCREEN / DISPLAY
Touchscreen
The display of the Stromer is equipped with a resistive touch screen.
The riding display shows your speed and information regarding the ride. You can change between
riding displays by pressing the touch screen until
the desired information is being displayed.
The Stromer provides you with full support at the
press of a button. The boost mode accelerates you
up to 20 km/h or 12 km/h even without pedaling.
Activate boost mode by keeping the plus button
on the handlebar pressed. The boost mode is activated after 2 seconds. The touch screen shows
BOOST.
That means that the touch screen does not respond to touch, like capacitive touch screens, but
responds to gentle finger pressure and can therefore easily be operated with gloves. Gentle pres-
Theft protection
Activate lock
The Stromer offers optimal theft protection. You
can lock the Stromer with a PIN when you switch
it off. The Stromer can then only be switched on
by re-entering your PIN.
1. Press the Power button to get to the shortcut
display.
2. Select LOCK.
The theft mode is activated when the locked
Stromer is moved.
The Stromer can in this case only be returned from
theft mode by using the Stromer OMNI App. This
makes the Stromer very unattractive for thieves.
Your Stromer automatically switches off when it
has not been switched off or locked, but has not
been used for a prolonged period. However, the
lock is not activated in this case.
Is the battery of your smartphone empty? – No
problem. The Stromer has been equipped with a
USB charging socket. Connect your smartphone to
recharge the battery.
The charging socket is located in front on the daytime running light and is sealed by a rubber lip.
Deactivating the lock
Proceed as follows to deactivate the lock:
1. Press the Power button.
2. Enter your PIN using the touch screen.
Stromer OMNI App
Get the maximum out of your Stromer. Install the
Stromer app on your smartphone and discover the
world of Stromer.
The Stromer app is the easiest way to configure
your Stromer for your needs. Fine-tune the support mode to your personal needs.
The app also shows you the position and the battery charging state – even when you are not near
the Stromer.
USB CHANGING SOCKET
Only the ST2 and ST2s models have this feature.
18 19
Only connect your smartphone when the
pedelec is standing. Do not change your smartphone while riding.
Range
The achievable range per charge is dependent on
various factors:
• Support level: The higher the support level
used, the lower the range.
• Riding style: You can save energy with the optimal use of the gear shift. In lower gears you
need to use less power, the support will be less
and your Pedelec’s drive consumes less energy.
• Ambient temperature: A battery discharges
faster in cold weather.
• Weather and vehicle weight: In addition to
the ambient temperature, wind conditions also
have influence on the range. More force has to
be applied while riding through strong headwinds. The weight increases with luggage etc.
and more power is also then needed.
• Technical condition of your Pedelec: Too low
air pressure in the tires increases the rolling
resistance. Dragging brakes also affect range.
• Battery capacity: The battery capacity indicates the capacity of a fully charged battery,
to store a certain amount of electricity. As the
capacity decreases with the increasing age of a
battery, the amount of storable energy in a full
charge also decreases.
• Road quality and the route profile: Rough pavement or gravel reduce the range. You can ride
much further on flat surroundings than when
riding on slopes.

HANDLING THE BATTERY
Safety notes concerning the
battery
• Only charge the battery with the charger it belongs to. The use of other chargers poses the
risk of fire.
• Do not drop or throw the battery and avoid
strong impacts. The battery might otherwise
leak fluid, start a fire or explode.
• Do not apply force to the battery. The integrated
protection mechanism may be damaged when
the battery is deformed. This may result in fire
and explosion.
• Do not use the battery when it is damaged. The
liquid contained may leak and contact with the
eyes may result in blindness! Avoid contact,
otherwise rinse off the liquid with lots of water
and immediately consult a doctor.
• Obtain information regarding the currently valid regulations when you want to transport the
S-pedelec, e.g. by car.
The battery is considered a hazardous good!
Remove the battery when you want to perform
any kind of work on the S-pedelec, e.g. mainte20 21
nance or assembly. Unintentionally activating the
On/Off switch might lead to injury or an electric
shock.
• Don’t ever open up the battery; This can cause
the battery to short circuit. All warranty and
guarantee claims expire when the battery was
opened.
• Do not store the battery with metal objects
that may cause shorts, e.g. office clips, nails,
screws, keys, coins. A short circuit may cause
burns or fires.
• Keep the battery away from heat, e.g. strong
sunlight and fire. There is a risk of explosion.
• Protect the battery from coming into contact
with water and other fluids. Contact may damage the protective circuit and the protective
mechanism of the battery. This may cause fire
and explosions.
• Do not clean the battery with a pressure washer. Use a damp rag when cleaning the battery.
Never use corrosive cleaning solutions.
• In the event that fumes escape after inappropriate use or damage, ensure exposure to
fresh air and consult a doctor if you experience
any medical problems. Before starting a ride,
the battery must be fully locked in place in its
holder and the battery box must be closed. You
may otherwise lose the battery while riding.
• Prevent deep discharging of the battery. It may
cause irreversible damage to the cells.
• The battery is exclusively intended for use with
Stromer electrical bicycle drives. Inappropriate
use or wrong handling may cause injury or a
fire. Stromer is not liable for damage caused by
inappropriate use.
• Never send a battery in the mail! Batteries are
hazardous goods. Only send batteries for your
S-pedelec through your Stromer dealer. The
battery may overheat and catch fire under certain circumstances.
• The battery may not be disposed of with domestic waste. The sales outlet will take it back and
will ensure appropriate disposal.
• Never store several batteries on top or next to
each other. This may lead to overheating and
fire.
Storing the battery
Store the battery in a dry and well-ventilated
place. A room temperature of approx. 20 °C is
optimal to prevent loss of capacity. Only use the
battery for rinding the Stromer in cold conditions.
Store it in a warm environment, which increases
the range. Ensure that the Stromer is switched off
when you want to store your battery in your bike.
Check its charging level approx. every 4– 8 weeks
and recharge it as required.
Store the battery with a battery charging state of
at least 40% when you do not intend to use it for a
prolonged period, e.g. during a winter break.
This is the most effective way of preventing deep
discharging. Ensure that the battery is never
stored in a fully discharged state, as this may lead
to deep discharging and irreversible cell damage.
Possible guarantee or warranty claims may then
become void.
The battery must be recharged within 2-3 days after it has been fully discharged in order to prevent
deep discharging.
ENGLISH
Storage at a battery charging level of 40-60%
is best suited to preserving your battery. Please
consider that this shortens the period after which
deep discharging is possible when compared to a
fully charged battery! The capacity of a battery decreases with age, even when it is well-maintained.
You should change a battery that has not been
used or recharged for a prolonged period before
you install it in your S-pedelec.
Pull out the battery.
Permissible storage temperature range:
-20 – 60 °C
Permissible discharging temperature range:
-20 - 60 °C
Permissible charging temperature range: 0 – 50 °C
Close the battery box. Press with your flat hand
onto the flap until it latches with a soft click and
then pull the key out of the lock.
Removing the battery
Open the battery box with the appropriate key.

2.
The battery is very heavy, so take care not to drop
it. You could get injured and/or the battery might
get damaged.
Inserting the battery
Place the battery into the battery box. Take care
that the connector points downwards and that the
lettering THIS SIDE UP is visible on top. Push the
battery downwards until it latches.
Push the key into the lock applying gentle pressure and turn it in a clockwise direction until the
battery box opens.
Never leave the key in the lock. You might get
injured by the protruding key or clothes might get
caught on it, which might lead to a fall.
Always pull the key out of the lock and keep it
at a safe place to ensure that it does not break
or get lost.
Safety information regarding
the charger
Read the operating instructions for the charger before beginning to charge the battery.
You can change the battery of your Stromer while
it is installed in your S-pedelec. However, you
can also remove the battery from the S-pedelec
and charge it in another place. It is particularly
advantageous to charge it in a warmer environment (room temperature) when it is cold outside,
in order to shorten the charging period. Avoid
charging processes below 0 °C or above 40 °C and
in tightly sealed spaces. The charging process is
automatically stopped at temperatures below 0 °C
or above 40 °C.
Please note that a sudden change of temperature from cold to warm can cause condensation
to build up in the charger. Avoid this by storing
the battery in the same place where it is charged.
Only use the charger supplied or a charger released by Stromer to avoid the risk of fire.
22 23
Use the charger in a dry room and don’t cover it up
while it is in use. It could otherwise short circuit
or cause a fire.
Check the mains voltage before connecting the
charger! The voltage of the power source must
correspond to the information on the type plate
of the charger.
• Always pull the plug out of the socket before
cleaning the charger.
• The charger should be disconnected from the
mains once the charging process has been
completed.
Charging the battery externally, outside
the S-pedelec
First connect the charger to the mains pug (LEDs
light up red and green) and then to the battery.
Hold the charging cable loosely in your hands and
bring it gradually closer to the socket of the battery.
For safety reasons, always place the charger
on a dry, non-flammable surface.
A defective battery should neither be
charged nor used any further. A battery can become warm while charging. It must not get hot.
When the battery heats up strongly, immediately
terminate the charging process.
Never ride when the battery is not inserted.
The battery compartment can in this case not be
locked. This poses an additional risk of falls and
injuries.
Charging the battery
Always read the charger information first.
The magnets will help you to position the plug
correctly.
The LEDs in the charger light up in orange and
green during the charging process.
The LEDs in the charger light up in green when
the battery has been fully charged. Separate the
battery/Stromer from the Stromer charger and
then the charger from the mains connector.
Charging the battery internally in the
S-pedelec
The connection for the charging cable is located
on the left side of the down tube, slightly below
the connection to the head tube.
Open the cover of the charging socket.
1. Connect the charger to the power mains. The
integrated LEDs light up in red and green.
2. Hold the charging cable loosely in your hands
and slowly move it near the socket of your
and a percent value. The Stromer automatically
switches off the motor and changes to bicycle
mode (no support) when the battery is empty.
The bar above the battery charge status indicates
the current energy flow. The display helps to ride in
an energy-saving way with a large driving range.
The longer the bar, the higher the energy flow.
The bar points from right to left as soon as the motor provides support.
SERVICE / MAINTENANCE
Regularly have your S-pedelec inspected by
a Stromer dealer. These experts can identify damaged and worn parts and are able to advise you in
selecting replacements. They will also check the
current software status and ensure that important
updates that improve safety and riding comfort
have been installed.
Refrain from repairing key parts yourself (frame,
forks, handlebars, stem, headset, brakes, lights).
The battery is charged during brake mode, so the
dark bar points from left to right.
Your S-pedelec can only function safely and
effectively if you replace parts with suitable, authorized replacements. Please consult your manufacturer, importer or Stromer dealer for advice on
suitable replacement parts.
A small part of the battery energy is saved in order
to sustain the basic functions of your Stromer and
Only replace broken or worn parts with original replacement parts from the manufacturer or
parts approved by your manufacturer. This is prescribed for some components and an appropriate
list is provided in the “Exchange of components of
the fast pedelec” section.
In this case, using non-original or non-approved
parts also invalidates the registration of the
S-pedelec. The use of other non-approved parts
generally invalidates the warranty and guarantees with the manufacturer for other parts.
Charging duration
The charging time may vary according to the version and the model of the battery and the charger.
Accurate charging times are provided in the information at www.stromerbike.com/support.
Charging status indicator
The driving display provides the option of tracking the battery charge status of your Stromer. The
battery charge status is shown in the form of a bar
keep you safe. The lighting and display still work
for approximately another hour when the battery
is empty and the motor support has stopped.
ENGLISH
Stromer. The magnets will help you to position the plug correctly.
3. Connect the Stromer charger with the Stromer.
The LEDs light up in orange and green.
If you install non-original or the incorrect
replacement parts, this can lead to a severe loss of
function! Tires with bad grip or tires that were not
designed for use in S-pedelecs, brake pads with
inappropriate friction coefficient and wrongly
used or badly designed light-weight components
can cause accidents with the most severe of consequences. The same applies for improper assembly!
Screws and torque spanners
When working on the S-pedelec, please ensure that all screws are tightened to the correct
torque. The required torque is printed on many
parts with a screwed connection. This amount is
stated in Newton meters (Nm) and this work
should be carried out using a torque wrench. Best
suited are torque wrenches that slip and provide
an acoustic signal when the predefined fastening
torque is reached. Otherwise, screws may snap or
break. If you don’t own a torque wrench then you
should always leave this work to a Stromer dealer!
A table with the most important fastening torques
for screw connections is provided in the “Screw
connections” section.

• Open live parts should only be maintained and
cleaned at a Stromer dealer!
• Remove the battery before cleaning your
S-pedelec. Ensure that the battery box is again
completely closed.
• Ensure that you do not touch and thus possibly
connect contacts when cleaning the battery.
You risk being hurt and the battery may suffer
damage if the contacts are live.
• Cleaning with a high-pressure cleaner may
damage the electrical system. The high pressure might also push cleaning liquid into
sealed parts and thus damage them.
• Avoid damage to cables and electrical components. When this has happened, the S-pedelec
must be deactivated until it has been inspected
by a Stromer dealer!
Switch off the electrical system, remove the
battery and close the battery box before performing any kind of work on your S-pedelec.
Chain / Drive
The drive chain must be regularly cleaned and
lubricated to ensure appropriate functioning (see
the “Deadlines and inspection work” section). Dirt
can be removed with the normal pedelec wash.
Otherwise you can clean the chain by rubbing
it with an oily cloth. When the chain is clean, it
should be greased at the joints with suitable lubricant. After being left to soak, the excess lubricant
should then be removed.
Chain tension
To ensure that the chain and gears can work safely, the chain must have a certain level of tension.
Otherwise it can come off and lead to a fall. Chain
gear systems tense the chain automatically.
Dirt and permanent strain wear the chain.
The chain should be replaced as soon as it can be
significantly lifted (approx. 5 mm) from the front
chain ring with your fingers.
Replacement of the chain is to be expected after
approx. 1500 km, depending on the load.
Chain OK
Chain worn
Many modern chains for derailleur gear systems
no longer have chain connectors. Special tools
are required to open/exchange/close them. They
should be exchanged by a Stromer dealer.
Other chains are supplied/mounted with chain
joints. In some cases, these can be opened without the need for tools. These chain connectors can
also be used to repair a damaged chain on a ride,
if they have the correct width for the drive train.
Rims are subject to a great deal of strain
and are vital to your safety on the bike. They wear
during riding. Do not ride with a rim once you can
see damage. Have them checked by a Stromer
dealer and replaced, as required. Wear can weaken rims and lead to falls and serious accidents.
You should also regularly check your pedelec’s tires. The minimum and maximum permitted
tire pressure is printed on the side of the tires.
Please adhere to these levels, otherwise the tires
could slip off the rims or explode!
Tires are wear parts. You should therefore
regularly check the pressure, tread and condition
of your tires. Not every tire is designed for every
type of use.
The tires of an S-pedelec may only be exchanged
for authorized products that were approved by the
manufacturer. Please take note of the correct size
and the ECE quality test marker. It is essential to get
advice from a Stromer dealer when selecting tires.
All tires used with a Stromer must have an Epermit for fast e-bikes according to ECE R75. For
example: E4 75R 0007911
The following tire dimensions are permitted for
the Stromer:
Customs designation ETRTO size
26x1.75 47-559
26x2.00 50-559
26x2.10 53-559
26x2.10 54-559
26x2.15 55-559
Dealing with punctures
You need the following equipment to repair a tire
puncture:
• Plastic tire lever
• Allen key for quick-release axles
• Air pump
• Spare tube
The quick-release axle must first be removed with
an Allen key before the wheel can be removed.
Please obtain information from the operating
instructions of the component manufacturers,
which are available online.
dealer when you are not sure how to change a tire.
Please remove the battery from the battery box
before performing any maintenance work. Never

You can avoid this problem by applying the
brake lever before transport and then fixing it in
this position using a strap. This prevents any air
from entering the hydraulic system.
When you come to clean the braking system,
please first read the instructions provided by the
component manufacturer.
Safety instructions for hydraulic disk
brakes
Avoid permanently braking for longer periods, as can be the case during long, steep descents. Otherwise this can allow vapor bubbles to
form and cause a complete failure in the braking
system. This could result in serious falls and injury.
The brake lever must not be applied if the
S-pedelec is on its side or upside down. Otherwise
air bubbles can enter the hydraulic system which
could cause the brakes to fail. After transporting the bicycle, check if the pressure point of the
brakes seems softer than it was before. Slowly apply the brakes several times. This allows the braking system to discharge any bubbles.
If the pressure point remains soft, please refrain
from riding. The Stromer dealer must bleed the
brake.
You can get more information about your
S-pedelec’s brakes as well as cleaning and maintenance in the operating manual provided by your
manufacturer or on the manufacturer’s website:
www.stromerbike.com/support
Gears
Gears are vital to your safety on the bike!
Please read the operating instructions supplied to
you by your manufacturer and familiarize yourself
with how to operate the S-pedelec and switch
gears before your first ride. Allow your Stromer
dealer to undertake any work on your bicycle’s
gears! Work that is improperly carried out endangers your safety on the S-pedelec!
Information regarding the gears of your
S-pedelec can be found in the manufacturer’s instructions at www.stromerbike.com/support and
on their websites on the Internet
Modern S-pedelec technology provides high
performance, but must be regularly maintained
by qualified persons. This requires specialist
knowledge and specialist tools. Leave the work on
your S-pedelec to your Stromer dealer!
Work that you can safely perform yourself is
highlighted in bold. To ensure that your bicycle
remains in a safe condition and fulfills the conditions of the warranty, the following terms apply:
• Clean your S-pedelec after every ride and check
it for possible damage.
• Have inspections carried out by the Stromer
dealer.
• Check your S-pedelec every 300 – 500 km or
every three to six months.
• Check that all screws, nuts and quick release
axles are secure.
• Use a torque wrench to tighten screw joints!
• Clean and grease moving parts (excluding
brake surfaces) according to the manufacturer’s
instructions.
• Have paintwork touched up.
• Ask a specialist retailer to replace any broken
and worn parts.

ENGLISH
Working on the S-pedelec requires special knowledge, experience and special tools! Only allow Stromer dealers to work or check key parts of the bicycle!
Screw connections
It is vital that all bolted connections on the
S-pedelec have the correct torque in order to ensure that they are secure. Too much torque can
damage the screw, nut or component. Always use
a torque spanner to tighten screw joints. You are
not able to correctly tighten these bolted connections without this specialist tool!
If a component specifies a torque for its bolted connections, then this should be strictly adhered to. Please read the instructions provided by
the manufacturer, which often list the correct
mounting torques.

WARRANTY, DEFECTS, WEAR
TECHNICAL DATA
You were given the warranty and limitation of liability separately at the time of purchase of your
S-pedelec. You can also consult them anytime at
www.stromerbike.com/support.
Permitted total weight of Stromer S-Pedelec: 140 kg
Vehicle including battery + driver + luggage + trailer
Wear
MOTOR
Take note that the components of the S-pedelec
are subject to higher wear than the components
of a bicycle without an additional drive. This is
due to the greater weight of the vehicle and the
higher average speed that is achieved through the
propulsion.
This higher wear is not a defect and is not subject
to warranty.
Typical components affected are:
• Tires
• Drive components
• Spokes
• Brake pads
The battery is subject to aging and therefore a
wearing part. Please take note that age and duration of use affect the battery, e.g. result in a clearly reduced driving range. This must be considered
when planning trips. Exchange our battery in due
time for a new one. Replacement batteries are
available from your Stromer dealer.
