WHAT IS AN E-BIKE ?
An e-bike is a bicycle with an electric propulsion unit which provides assistance when cycling. The
motor is activated by pedalling, which is registered using a special sensor located in the bottom bracket.
This means that you must continue pedalling the e-bike, the motor will only provide you with assistance.
You can also propel the bike using the control button or accelerator, but only up to the maximum
permitted speed, i.e., 6 km/h (i.e., for assistance when pushing the bike).
The maximum speed of the e-bike with assistance from the motor is 25 km/h, within a tolerance of
10% (when this speed is achieved the motor is switched off and you continue pedalling as you would on
a normal bike). When the battery is discharged or if the motor is switched off, you can ride the e-bike like
you would a normal bicycle, without any resistance.
From the aspect of the Road Traffic Act, an e-bike is considered a standard bicycle, which mean that
you can ride it on public roads and cycle paths and do not require a driver’s licence. You are only
required to wear a helmet if you are under 18 years of age.

to adhere to these warnings may result in injury to you or another person, possibly to damage to your
property or the property of others.
• Always follow the instructions for use in order to avoid the risk of fire, injury by electric current or
general injury.
• Before riding the bicycle, make sure that there are no loose or damaged joints. Check the brakes
function and the tyre pressure.
• In the event that any part of the e-bike is damaged, take it to a professional servicing facility for repair.
• Neither the manufacturer nor the seller is liable for accidental or subsequent damage or for damage
arising directly or indirectly as a result of incorrect use of this product.
Comment:
Comment: The weighted acoustic pressure (A) level on the ears of the cyclist is less than 70 dB (A).
E-BIKE SYSTEM
The e-bike is equipped with a control unit with LCD panel which controls the electric propulsion unit.
You can choose from several levels of performance (assistance) intensity. Motor assistance is reduced
as speed increases and is disconnected when a speed of 25 km/h is reached. This corresponds to the
requirements of the relevant European standard so this product is still considered a bicycle and not an
electric scooter.
The e-bike motor will come on after the pedals are turned by approx. ¼ of a rotation. Models equipped
with a BOSCH motor will start providing assistance when the pedals are turned by approx. 1/8 of a
rotation. The motor will disconnect 1-2 s after pedalling ceases.
The e-bike also includes a “walking assistance” function. In this mode the bike travels at a speed of 6
km/h without the need to pedal, which makes it easier to push the bike. This function is not intended for
extended cycling.
NOTE::
NOTE
A detailed description of the controls for the control unit is given in separate instructions for use,
which are included in the e-bike packaging.
INFORMATION ABOUT THE BATTERY
The Li-ion battery has a very low self-discharge rate. From the first charge cycle the battery must be
maintained constantly in its work cycle (discharge/charge) so that even if the e-bike is not being used, in
the winter for instance, the battery must still be charged at least once every 4 weeks.
We recommend that you perform one full charge cycle (discharge/charge) before you begin to use the
bike. The battery can subsequently be charged at any time. Maximum battery capacity is achieved after
approx. 5-10 charge cycles.
Keep the battery charged and always recharge it after you ride the e-bike, not before riding it.
Only use the charger supplied with the e-bike to charge the battery.

FACTORS AFFECTING THE RANGE OF THE E-BIKE
The e-bike’s range cannot be accurately determined as it is affected by many factors. The range
displayed on the display can change every time the battery is charged because the system adapts to the
amount of stress placed on the e-bike after it was ridden last.

IMPORTANT INFORMATION – BEFORE YOU SET OFF
SAFE CYCLING RULES
All cyclists must adhere to the basic rules for cycling safely on roads as stipulated by generally binding
legal regulations. There are also specific rules for cycling in offroad.
Always wear a cycle helmet!
Apparel: correct cycling apparel can improve your experience of riding your bicycle. Special functional
cycling apparel can also increase your safety – bold colours and reflective materials improve your
visibility. Cycling gloves are also very practical. Be careful wearing loose clothing, particularly
trousers, which can easily get caught in the chain.
Rules for cycling on public roads: The basic rule is to behave the same as you would when driving
a car. Cyclists are fully-fledged road traffic participants.
Cycling at night: If you cycle at night you must equip your bicycle with lights, if it does not already
have them. Apparel made from reflexive fabrics is an important supplement to cycling at night.
Cycling in poor weather: For cycling under poor visibility conditions bicycles can be
additionally equipped with devices for light signalisation and lights according to the valid bylaw.
Fluids: You should never forget a cycle bottle (bidon) with fluids (can be easily drunk from
when cycling, unlike bottles with a screw cap) when going on a cycle trip or longer journey, because your
body must receive the fluids it needs while it is performing.
WARNING: When using the e-bike on public roads abide by the locally valid road traffic laws.
These laws may require that the bicycle and rider carry specific equipment, or regulate how you
ride your bicycle or transport cargo or other persons.
MECHANICAL ADJUSTMENT OF THE E-BIKE
WARNING:
WARNING:
Always remove the battery before carrying out any work on the e-bike.
bike.
Frame:
Frame: You have probably already chosen the correct size of frame with the help of your retailer.
Saddle and seat post:
post: The saddle can be adjusted in three directions – up/down, forwards/backwards,
at an angle.
Saddle height:
height: Sit on the bike and rest your feet on the pedals with one pedal in the position lowest to
the ground. If the saddle is at the correct height the leg with the foot on this pedal should be slightly bent
at the knee. Saddles that are too high cause excessive strain on the back and stretch the legs and hips
too much. A saddle that is too low strains the knees and thigh muscles. The rule is that if you have both
feet on the pedals, while the leg being measured is in front, there should be a vertical line passing
through the knee and the centre of the pedal.
Handlebars and stem:
stem: The maximum permissible extension height is marked on the stem. Never
extend the stem above this mark! This will prevent damage to the stem and the risk of it potentially
fracturing and resulting injury!
Luggage carriers:
carriers: The bicycle is suitable for installing a carrier or child seat. If you equip your bicycle
with a carrier, be aware that the frame is constructed to carry a total weight of 120 kg, i.e., the cyclist and
luggage. Carrying excessive weight may cause damage.
EN - 7
PRE--RIDE INSPECTION
PRE
The service life of the frame or components is influenced by the design and the used material, as well
as maintenance and the intensity of use. Regular inspections by a qualified professional should become
a matter of course and will prevent many technical issues the consequences of which could be
catastrophic. You are responsible for inspecting your e-bike before every ride.
Before you set of
off: Test the bicycle by lifting it approximately 10 cm above the ground and letting it go.
This will establish that nothing is loose. Then perform the following quick inspection:
1. Wheels and tyres:
tyres: Check that the wheels are centred and that no spokes are loose or missing. Check
the quick-release screws in the wheel hubs, the tyre pressure and wear. The maximum tyre pressure
is specified on the rim or tyre.
2. Brakes
Brakes:: Press both brake levers and push the bike forward. The brake shoes should press against
the rims (discs), but the brake levers should not touch the handlebars. Make sure that the cables are
not frayed or excessively twisted. The cables stretch and the brake shoes (pads) become worn over
time, which is why the brakes should be regularly adjusted and the worn parts replaced when
appropriate.
chain:: Clean the chain regularly and lubricate it using the appropriate product. The
3. Gear system and chain
chain naturally stretches over time and must be regularly replaced. Stretched or damaged chains can
seriously damage the chainset or sprocket wheels.
4. Frame
Frame:: A bent or cracked frame should be replaced immediately. Never try to straighten or fix the
frame yourself.
5. Joints
Joints:: Check that the quick-release mechanisms and screws are not loose.
Battery:: Check the charge in the battery.
6. Battery
CYCLING TECHNIQUE AND ADJUSTMENT OF THE E-BIKE
After you ride the bicycle for the first time we recommend you check both the brakes, and the front
and rear derailleur, as they may need additional adjustment.
Gear system:
ystem: You have a gear changer on the handlebars, which is used to control the rear derailleur.
Do not try to change gears when you are not pedalling forwards. It is very important to release the
pressure on the pedals when changing gears, this allows the chain to change smoothly between the
individual gears and reduces the risk of bending the chain or damaging the chainset or sprocket wheels.
When cycling up or down an incline, change into the appropriate gear in time. Changing gear when
cycling up-hill, when the chain is under strain, causes excessive stress on the entire gear shift system.
Feet:
Feet: Your instep should be on the axis of the pedal. Special cycling shoes make pedalling easier and
more effective.
Torso:
Torso: Keep your torso relaxed and in a natural position. Leaning forwards at an angle of
approximately 45 degrees is especially effective as it allows the strong buttock muscles to work better.
Position in the saddle:
saddle: Do not remain in the same position. Move back on the saddle to increase
power and keep the rear wheel on the ground when cycling down steep inclines. Lean against the
handlebars and sit on the tip of the saddle when cycling up steep inclines to keep the front wheel in
contact with the ground.
Braking:: When braking while moving straight forward use both brakes, with more pressure on the front
Braking
brake lever. However, because there is a higher risk of falling over the handlebars when braking with the
front brake, you must learn to gradually apply pressure to both brakes with more pressure on the front
brake lever to avoid the risk of falling over the handlebars. Never use the front brake alone to avoid the
risk of falling over the handlebars.
You should apply pressure to the brake levers in such a manner that the wheels do not lock up. As soon
as a wheel locks the tyre loses adhesion with the road surface and this reduces the effect of the brakes.
Before you cycle on the road, try braking in an area with low traffic.
When braking in a bend, never use the front brake, or only very moderately! Apply pressure to the front
brake lever before the bend (possibly also to the rear brake lever if necessary), do not brake while
travelling around the bend if possible or only use the rear brake. Using the front brake in a bend or on an
unpaved surface reduces control over the direction of the bike and increases the risk of the front wheel
slipping and the cyclist falling.
EN - 8
Remember that the braking distance and the time needed to stop increases substantially in poor
conditions (rain, sub-zero temperatures).
Always be prepared to brake if you are cycling down a steep incline and in areas with limited visibility.
Be careful of any bumps with sharp edges, ducts or drainage channels (risk of tyre defects or falling).
OTHER RECOMMENDATIONS
Using a trailer behind the bike:
bike: A trailer is intended for transporting children along pavements, not very
busy roads and trails with a level surface during the day. Use it in compliance with the specified limits.
You can also transport cargo in the storage areas intended for this purpose if this does not endanger the
children in any way. If you want to use the child trailer when visibility is poor, for instance at dusk or when
it is dark, we definitely recommend that you use a set of lights complying with safety standards.
NonNon-recommended use
use:
se: We do not recommend using the trailer in any other way than in the way
specified above. It is not intended for transporting animals together with people, when cycling along
uneven terrain off paths, using it for commercial purposes or overloading the trailer, riding too fast or
amateur performance of repairs or modifications. The weight of the cyclist plus trailer must not exceed
120 kg. The manufacturer is not liable for any damage incurred as a result of use of the trailer in a
manner not recommended by the manufacturer. Such use is always at the user’s own risk.
Use of child seat
• After installing the child seat, always check that all the parts have been installed according to the
instructions and that all the connections have been tightened properly. Always use an approved child
seat.
• The handling of the e-bike changes when transporting a child. Make a trial run with the child to try out
how the bike now behaves.
• With regard to the fact that the possibility of the child releasing itself from the protective system cannot
be avoided, the spokes and chain of the e-bike should be covered if possible in the area where the
child seat is installed.
• The parts of the suspension seat post should also be covered so the child cannot catch its fingers in
the moving seat post mechanism.
• Never transport a child without a seatbelt and without attached foot rests.
• With regard to the fact that there is an increased risk of injury to the child in the case of an accident
(fall), you should never transport children in the child seat without a cycle helmet.
• Never leave the child alone in the child seat when you park the e-bike.

CHARGING THE BATTERY
CHARGING THE BATTERY of a BOSCH propulsion system – see Original instructions.
The li-ion battery has a very low self-discharge rate. The battery must be maintained in a working
cycle (charge/discharge) from the first time it is charged, so that even if the e-bike is not being used, in
winter for example, the battery must be charged at least once every 4 weeks.
We recommend that you perform one full charging cycle (discharge/charge) when you begin to use
the bike. You can then charge the battery at any time.
The battery is fully charged if all the pilot lights on the scale showing the battery charge level are lit.
The scale on the handlebars controls only shows the approximate battery charge level. The indicator on
the battery shows a more accurate charge level. If only one pilot light is on/flashing, the battery requires
recharging.
If the battery charge is low, the motor stops running smoothly and may run with interruptions (in fits).
In this case you must switch the electric propulsion system off. Continue cycling without motor assistance
and ensure that the battery is recharged. You can continue using the electric propulsion system as soon
as you recharge the battery.

bike. Do not try to carry out any
repairs or adjustments which you are unable to perform perfectly. Incorrectly performed repairs or
adjustments may lead to accidents or to loss of your warranty.
BRAKES
The right brake lever controls the rear brake and the left brake level controls the front brake.
The brake lever should always be attached firmly to the handlebars. It should not touch the
handlebars when pressed. If this occurs, the brake cable must be tightened.
The brake consists of two arms. Regularly check that the brake is correctly centred. If not, let a
professional carry out the adjustment. Every cyclist should be capable of a least basically adjusting the
brakes. Major repairs, such as tightening or replacing the cables, or replacing the brake pads, should be
entrusted to a servicing facility.
Correct brake functioning also depends on the condition of the wheels themselves. If there is play in
the wheels or if they are buckled and wobble to the sides or up and down when turned, they need to be
adjusted or trued. Truing the wheels is not easy – contact a professional. If the brake discs are buckled or
otherwise damaged, they must be replaced. The brake shoes (pads) will wear over time and must be
replaced. Excessive braking noise may be caused by inappropriate adjustment.
Cables and Bowdens should be checked regularly. Check to make sure that the cables are not frayed
and the Bowdens are not bent or cracked.
Pay attention to the following points:
• Always test the brakes before going for a ride to make sure they are fully functional.
• Press the brake levers while you are standing still, using more force than usual to exclude any
potential damage to the connecting elements or cables.
• In the case of rim brakes, check that the brake shoes and rims are clean and are not contaminated
with lubricant (oil) residues or other greasy products. Check that the entire surface of the brake shoes
fits tightly to and encloses the rims and that it does not touch the sides of the tyres.
• Check the brake shoes regularly, they should not be excessively or irregularly worn.
EN - 12
• New brake pads in disc brakes will only achieve optimum performance after a specific minimum period
of use, brake carefully when they are new and be aware that the braking performance of new pads will
increase.
• Always keep the surface of brake discs clean and degreased.
WARNING::
WARNING
Always check the Bowden cables to make sure they are not damaged.
In your own interest, it is better to entrust servicing work on the brakes (apart from normal
maintenance) to a specialised seller!
Adjustment of the height of the handlebars may affect adjustment of the brakes!
"V" type brakes
Brake adjustment
1. Press the brake shoe against the rim and tighten the retaining screw
(socket screw).
2. After releasing the brake shoe, the B and C distance between the
brake shoe and the rim should be approximately 1 – 2 mm.
3. Use the regulating screws to adjust the distance between the shoes
and the side of the rim to 1 mm (evenly on both sides).
Comment:
Comment: In some types of brake there is a pretension regulating
screw on only one brake arm.
4. Press the brake lever several times all the way to the handlebars to
verify the brake action and then check brake adjustment once more.
Adjustment of the brake shoe
The brake shoe should be aligned according to the attached image.
arrow = direction of wheel rotation
Disc brakes
Disc brakes are distinguished by their excellent braking performance and good resistance to poor
weather. They react much more powerfully than rim brakes when it is wet. They also do not require a lot
of maintenance and do not wear the rims like rim brakes. However, disc brakes have a tendency to be
noisy if they are wet or dirty.
The brake levers can be adjusted to the size of your hands, which leads to more effective control. In
most cases they are adjusted using a small socket screw in the lever.
In mechanical disc brakes, the range of movement of the brake lever increases as the brake pads
wear, which requires regular adjustment of the brakes. To adjust the range of movement of the lever use
a small screwdriver to turn the adjusting screw located in the lever adjustment case. Worn brake pads

can be compensated for on the brake lever to some degree. Loosen the connecting nut on the screw
through which the cable passes into the lever and then loosen the screw until the lever has the required
range. Then tighten the securing nut again.
Hydraulic disc brakes are equipped with a mechanism that automatically compensates for wear. To
adjust the range of movement of the lever use a small screwdriver to turn the adjustment screw located
in the case. Gas pockets can occur when braking continuously for extended periods. Release the brake
lever intermittently to avoid this. A gas pocket is a phenomenon that occurs when the fluid is heated,
when water or air bubbles in the brake system start to expand. This may cause the brake lever
resistance to fall suddenly.
Comment:
Comment: After disassembly of the wheel, we recommend you insert a
suitable spacing insert between the brake pads (C). If a wheel is not
fitted in the fork, do not press the brake lever. If the brake lever is
pressed without a spacing insert in place, the pistons extend more than
usual. If this occurs the brake disc (A) cannot be inserted back into the
calliper (B). Contact your seller to resolve this issue.
Check the wear of the brake pads (C) regularly. If the brakes produce
noise when braking, the brake pads may be worn to the usable limit.
Wait until the brakes are cool enough and then check the thickness of
all the brake pads. If it is less than 0.5 mm do not use the bike and
contact your seller.
If the brake disc is deformed or cracked, do not use the bike and contact
your seller.

GEARS
The gear system consists of derailleurs and gear levers, or a grip shift, cable lines and a chain. The
derailleurs include springs. Only change gear when the pedals are moving forwards. Never try to change
gear when not pedalling or when pedalling backwards. Never use force to try to change gear. Never lay
the bike down on its right side, this could damage the derailleurs.
If changing gear is difficult, slow or noisy, or if the chain falls off or rubs on various parts of the bike,
adjustment is necessary.
Easy and comfortable cycling
You will enjoy cycling and your performance when you learn to cycle so that the pedalling frequency
ranges between 70 / 90 rotations/min, which is the best performance/energy output rate. To ensure
optimum pedalling frequency you have various gear modes available, which will help you find the best
rhythm under various cycling conditions.
EN - 14
Please pay attention to the following points:
points:
• Do not stop pedalling when changing gear, but reduce the power used to pedal while you change
gear.
• After cycling in the rain, mud, etc., you should clean the moving parts of the gear system and lubricate
them.
• Do not change gear across the entire chainset or sprocket at once.
• Never change gear when pedalling backwards (reverse). This could cause the chain and derailleur to
lock.
Gear selection
selection::
• The right gear lever (or grip shift) changes the gears on the rear sprocket.
• The left gear lever (or grip shift) changes the gears on the chainset (if the bike has them).
• Various combinations of sprocket and chainset determine the choice of gear. As soon as you gain
more experience changing gear, you will recognise the gear most suitable for specific cycling
conditions.
Recommendations
If the bike is equipped with
with a front derailleur,
derailleur, the following gear
combinations should be used according to the picture to the left, in
ord
order to avoid increased wear
wear or even damage to the chain, sprockets
or chainset:
o
Large chainset (front) – small sprocket (rear)
o
Small chainset – large sprocket
o
Medium chainset – medium sprocket
Adjustment of the front derailleur – limit positions
The derailleur is equipped with limit screws which limit the range of movement of the derailleur and
prevent the chain from falling off the smallest or largest chainset.
Adjusting the lower limit
1. Change gear so that the chain rests on the smallest chainset and the
biggest sprocket. The gear change cable should not be pretensioned.
2. Turn the regulating screw in direction A or B so that the distance
between the internal chain guide and the chain is 0.1 to 0.5 mm.
Adjusting the upper limit
1. Change gear so that the chain rests on the largest chainset and the
smallest sprocket. The gear change cable should not be pretensioned.
2. Turn the regulating screw in direction A or B so that the distance
between the internal chain guide and the chain is between 0.1 and
0.5 mm.
EN - 15
The limit adjustment screws are usually identified as “H” (high) for “fast” gears and “L” (low) for “slow”
gears. “Fast” gears are gears when the chain rests on a large chainset and a small sprocket. If the
screws are not identified, their function must be verified by testing.
The aforementioned limits were adjusted before the bike was sold and should not change position
spontaneously during normal use.
Adjustment of gears
Gears are adjusted by pre-tensioning the cable in the lowest position of the derailleur. The derailleur
cable is prone to stretching, which reduces accuracy during gear changes. If necessary, the cable can be
tensioned or loosened by turning the adjustment screw through which the cable passes into the gear shift
lever (or grip shift).
Adjusting the rear derailleur–
derailleur– limit values
The derailleur is equipped with adjustment screws (again marked “H” and “L”), which limit the range of
movement and prevent the derailleur and chain from colliding with the wheel spokes or the chain from
falling off the smallest sprocket.
Order:
1.
Adjustment of the upper limit
1. Change gear so that the chain rests on the smallest chainset
and the biggest sprocket.
2. Turn the regulating screw so that the guide pulley is located
directly under the biggest sprocket and cannot move any
further in the direction of the wheel spokes. Adjust the gear
cable to its pre-tensioned position using the regulating or
locking screw.
2.
Adjustment of the lower limit
1. Change gear so that the chain rests on the biggest chainset
and the smallest sprocket.
2. Turn the regulating screw so that the guide pulley is directly
under the smallest chainset and cannot move any further in an
outwards direction towards the rear frame tubes.
The aforementioned limits were adjusted before the bike was sold and should not change position
spontaneously during normal use.
Adjustment of gears
Gears are adjusted by pre-tensioning the cable with the derailleur positioned so that the chain rests on
the smallest sprocket. The cable is prone to stretching as in the front derailleur. If necessary, the cable
can be tensioned or loosened by turning the adjustment screw by the derailleur or by turning the
adjustment screw through which the cable passes into the gear shift lever (or grip shift). After the cable
has been tensioned correctly, check to make sure that the chain jumps easily to the next sprocket. You
need to turn the crank arms for this or check that the system is functioning correctly while cycling.

WHEELS, TYRES AND VALVES
The wheels are subject to significant stress, which is caused by the weight of the cyclist and any other
items you may be carrying, and the unevenness of the terrain over which the bike moves. This is why we
recommend that you inspect the wheels regularly, particularly to make sure that their crucial components
are not excessively worn and that the wheels turn smoothly. If you have any concerns you should contact
a specialised seller (servicing facility). After each accident check the wheel spokes to make sure that
there is no damage.
Hub with quickquick-release mechanism
The front and rear wheels of most MTF bicycle models are equipped with easy-to-use quick-release
mechanisms, which simplify mounting and removal of the wheels.
Mounting the wheel
1.
Release the lever of the quick-release mechanism, loosen it by
several turns and then insert the wheel into the fork.
2.
Tighten the regulating nut until you feel slight resistance.
3.
Close the lever of the quick-release mechanism so that the side
bearing the word CLOSE faces outwards and so that the lever is
parallel to the fork. You must use a certain amount of force to close
the quick-release mechanism. When closing the mechanism you
will feel more resistance as the lever is pushed closed the last third
of the way, not before.
4.
Check that the wheel is correctly fitted in the fork and centred (that
the rims and tyres of the wheel do not graze the brake shoes /
pads, or possibly the rear fork structure).

Removing the wheel
Front wheel:
1. Disconnect the brake cable if this is necessary for removing the wheel from in between the
brake shoes.
2. Release the quick-release mechanism, loosen the regulating nut by several rotations and
remove the wheel from the fork.
Rear wheel:
1. Disconnect the brake cable if this is necessary for removing the wheel from in between the
brake shoes.
2. Change gear so that the chain rests on the smallest sprocket.
3. Release the quick-release mechanism and loosen the regulating nut by several rotations.
4. Push the derailleur backward, which will release the chain from the sprocket, and remove the
wheel from the fork.
Comment:
Comment: In the case of brake discs, we recommend you insert a suitable spacing insert between the
brake pads after you remove the wheel. If there is no wheel in the fork, do not press the brake lever. If
the brake lever is pressed without a spacing insert being inserted, the pistons will extend more than
usual. If this occurs the wheel cannot be re-assembled. See section BRAKES, page 12.

brakes do not graze the rim or the discs graze the brake shoes or pads. If necessary adjust
them slightly using the regulating screws.
Defects
In case of any defects, proceed in the following recommended manner:
1. Before you start removing the wheel, first of all check that the valve is not leaking. In order to
perform this inspection, pump the tyre up and apply saliva to the valve outlet. If bubbles appear
around the valve, this indicates that air is leaking from the valve, which means that the valve is
damaged or loose.
2. Remove the wheel, unscrew the protective cap, or the securing nut on the valve.
3. Press the tyre against the valve into the rim bed, then lift the tyre near the valve over the edge of
the rim and lift it along the entire circumference of the rim. If necessary, use tyre levers, never
use any tools with sharp edges to remove the tyre.
4. Remove the inner tube, pump it up, find out which part is damaged and repair it using an inner
tube repair kit (see instructions for use of the inner-tube repair kit).
5. Before inserting the inner tube back into place, check the condition of the tyre and the rim bed
and try to find the defective area and remove any foreign bodies from it (stones, glass shards,
nails, etc.). Also straighten the rim band.
6. Insert the inner tube back into the rim and inflate it a little, otherwise there is a risk that it will be
pinched between the rim and the tyre and puncture. Carefully pull the valve through the
appropriate hole in the rim.
7. Place the tyre back into the rim bed along its entire perimeter. Start next to the valve and use
tyre levers if necessary (most tyres can be reinserted by hand). The valve must be
perpendicular to the rim, not diagonal.
8 Use your fingers to move the tyre from side to side, left to right, along the entire circumference
so that it perfectly fits and to minimise the risk of the inner tube being pinched between the tyre
and the rim.
9. Inflate the inner tube and check that the fitted tyre is centred.
10. Mount the wheel into the fork.

Tyre pressure
Tyre pressure is a very important parameter which allows the tyre to roll smoothly and ensures a long
service life. We recommend that you check the tyre pressure with a manometer when inflating the tyres.
Also pay attention to various types of valve (see the “Valve” paragraph).
The size of the tyre and the tyre pressure range are given on the side of the tyre. The maximum
permissible tyre pressure is usually specified in bar, kilopascal (kPa) or PSI. The optimum range or
minimum tyre pressure is sometimes prescribed on the tyre. See below for the conversion rate between
the different pressure units:
1 bar = 1 atmosphere = 100 kPa = 14.50377 PSI
1 PSI = 0.06894757 bar = 6.894757 kPa
1 kPa = 0.01 bar = 0.1450377 PSI
WARNING::
WARNING
Never inflate the tyres to a pressure exceeding the maximum permissible pressure value. If the tyre is
overover-inflated it may selfself-destruct suddenly when you are cycling. When you use a device for
supp
supplying compressed air (e.g.,
(e.g., compressors at fuel stations),
stations), you will inflate the tyre to the required
pressure very quickly. This is why you should proceed very carefully when inflating the tyre and check
the tyre pressure using a manometer after inflation if possible.

Valves
Schrader valves are the same type of valve used on car tyres. In order to
inflate the tyre, you have to remove the valve cap and push the pump onto
the end of the valve. If you need to release air, press the middle of the
valve with your finger or an item with a sharp point.
Presta valves
valves, compared to Schrader valves these valves are smaller, are
more resistant to higher inflation pressure and have a more aesthetic
appearance. In order to inflate a tyre with this valve you need to remove
the valve cap and loosen the locking screw. Before inflation, press the end
of the valve briefly, which will release some air and empty the valve. Then
push the pump onto the end of the valve and inflate the inner tube. Don’t
forget to tighten the valve locking screw back in place.

Rims
Always keep the surface of the rims clean and free of grease. Greasy rims substantially reduce the
effect of the brakes.
The wheel rim is mechanically most highly stressed when cycling over uneven ground and when
braking. Friction as a result of braking causes wear of the rims. As soon as the wear on the rim reaches
certain limit values, the rim may start to deform under the pressure of the tyre. If in doubt contact your
retailer and ask them to check the thickness of the rim. Some modern rims are fitted with so-called wear
indicators by means of which critical wear of the rim is visible.

CHAIN
The chain transfers power from the pedals to the rear wheel and is one of the most highly stressed
components on the bicycle. This is why care of the chain deserves special attention!
attention! It is very important
to keep the chain clean and lubricated. Before lubricating the chain you must clean it thoroughly. Any
sand or small particles that adhere to the chain as you ride the bike rapidly reduce its service life. Correct
and regular maintenance substantially extends the service life of the sprockets, chainset, and front and
rear derailleurs. Under stress the chain stretches over time and needs to be replaced. If you do not
replace the chain in time, the chainset and cogwheels may be damaged. This is why you have to have
the chain measured regularly by your mechanic!
Adjustment and installation/removal
installation/removal
The chain is kept correctly tensioned by the derailleur.
The chain has special connecting pins which should only be disconnected and connected by a
specialised worker using a special tool. However, if you use a high-quality chain tool you can also
replace the chain yourself.
It is true that even the highest-quality chains always have a limited
service life and usability. The chain should be replaced when it can be
lifted more than 5 mm above the chainset (see pic.). The best way to
establish the wear on the chain is to use a workshop gauge, which can
be purchased from specialised shops, to check the chain spacing.
Chain wear can be monitored regularly using this gauge and the chain can be replaced at the right
time, i.e., not prematurely or too late. If the chain spacing exceeds the maximum permitted limit, the
other parts of the gear system, i.e., particularly the sprockets and chainset, can suffer excess wear.
This is why the chain should be inspected regularly and immediately replaced if necessary
necessary.
Chain care
The chain should be lubricated approximately once a month under normal cycling conditions. If the
bike is used more often, it should then be lubricated approximately every 200 km. When cycling under
difficult conditions (rain, dust, mud) the chain should undergo maintenance much more often, possibly
every time the bicycle is used!
There are a number of lubrication products intended for application to bicycle chains available on the
market. Proceed as follows when lubricating the chain:
1. Wipe off all excess lubricant residue from the surface of the chain with a dry cloth. Dirt will adhere
to this residue with negative impact on the service life of the chain, and of course there is the risk
of getting your clothes and also the bike itself dirty.
2. Apply the lubricant in small doses, but evenly over the entire chain, to the inner surface of the
chain pins. The sides of the chain should remain dry and clean.
3. After applying the lubricant remove any excess that adheres to the surface of the chain using a
dry cloth while turning the pedals counter-clockwise. Only lubricant that remains inside the
elements and not on their surface benefits the chain.
Special chain cleaning devices can be purchased from specialised shops (so-called chain washers),
which are capable of removing the dirt from even very dirty chains, and restoring them to their original
condition, thereby extending their service life. Investing in such a device is certainly worth it for people
who cycle often in difficult conditions.
During normal use, not under extreme conditions (rain, dust, mud), the average service life of the
chain is approximately 1,000 to 2,000 kilometres, but this varies in individual cases.

SUSPENSION FORK
The key prerequisite for proper functioning of the suspension fork is its cleanliness. Keep the sliding
surfaces on the suspension fork clean so that no dirt penetrates the seal. Wipe the fork down with a soft
damp cloth every time you ride the bike and spray a thin layer of silicone oil onto the sliding surfaces of
the fork or lightly wipe them with hydraulic oil.
If the fork is adjustable – damping, firmness and travel, you will be informed of this by the technician
when you purchase the bicycle and the procedure for use will be explained to you. Some fork models
have optional adjustment of firmness, which requires replacement of some parts of the fork. Always
leave this activity to an authorised servicing facility.
In air suspension forks follow the guidelines for pressure depending on the cyclist’s weight, specified
directly on the fork.
Correct functioning of the fork is only possible after it has been adjusted with regard to the cyclist’s
weight and cycling style. It generally applies that the fork should travel by about 10 to 25% of the
specified total travel distance when the bike is bearing the cyclist’s weight. Otherwise, the initial
configuration of the suspension needs to be adjusted.
In order to avoid reducing the service life of the suspension fork, you should pay attention to the
following before you ride the bike:
• Regularly check the fork to make sure there is no visible damage.
• The position of the brake shoe (pad) against the rim (disc) (optimally 1-2 mm), the play in the brake
lever (contact between the brake shoe (pad) and the rim (disc) should occur when the brake lever is
pulled in one-third of its range of movement).
• The firmness of the brake mechanism – press the brake lever and push the bike forward and back to
make sure no connections are loose.

Check that the chainset has all the required screws and that these are tightened properly, particularly
the bolt that attaches the crank arm to the axis. If the crank arm comes loose from the axle, you must
IMMEDIATELY stop and repair the defect, otherwise, even a short ride with a “loose” crank arm may
cause irreversible damage to the crank arms. The tightness of attachment of the pedals to the crank arm
must be checked in the same manner.

bicycle. Water can penetrate into the
bearings and the high pressure is capable of stripping away the lubricating oils and grease. It is always
best to clean your bike by hand. Never wipe your bike down without wetting it with water first, otherwise,
you will scrape the paint and the surfaces of components.
Lubrication:

bicycles.
• Do not apply excessive lubricant to the derailleurs. An excessive amount of lubricant causes dirt and
dust to adhere.
• Avoid applying lubricant to the rims, brake shoes and brake discs.
• It is a good idea to occasionally lubricate the rotating pins on the brake levers and arms.
• It is best to leave lubrication of the traction elements (cables and Bowdens), the hubs, headset, bottom
bracket and pedals to an experienced mechanic. These components must be completely
disassembled, cleaned, lubricated, reassembled and adjusted.

TRANSPORT, STORAGE AND DISPOSAL
TRANSPORT OF THE E-BIKE
If you transport the bicycle by passenger car, only use approved carriers, use of which is approved for
the specific vehicle.
If the bicycle is transported on a passenger car in the rain or similar poor weather conditions, it will be
exposed to a great amount of water, regardless of the speed of travel and intensity of the rain. Protect
electric parts and moving parts (cables, gearshift levers, chain) in particular using some sort of rain-proof
cover. It is also a very good idea to protect the saddle in such cases by wrapping it in plastic.
The bicycle should not be stood “upside down” during transport, i.e., attached to the roof of the vehicle
by its handlebars, because the handlebars could be subject to high dynamic force, which could lead to
material fatigue in specific cases and subsequently to destruction of this material. It is not permitted to
transport e-bikes on the roof of a car due to their increased weight (motor, battery). Recommended
methods of transport are on an e-bike carrier which is attached at the rear of the vehicle to the tow-bar.
Remove all parts that can be easily lost or removed, or stolen (i.e., pumps, bottles, bags, lights, etc.).
Adapt the speed of the vehicle to the relevant conditions (great sensitivity to side wind) and pay attention
to passing under lowered profiles, such as tunnels, underpasses and garages.

STORAGE OF THE E-BIKE
If you will be storing the e-bike for an extended period (e.g., over winter), follow the instructions below:
1. Before storage, clean the e-bike properly and lubricate the appropriate parts (particularly the
chain, chainset, derailleurs and rims).
2. Treat chrome parts and parts with a glossy surface with a product protecting against corrosion.
3. Check the tyre pressure, adjust it to the prescribed pressure.
4. Charge the battery. Don’t leave the charger connected to the mains or to the battery when
charging is complete. If stored for an extended period the battery should be regularly charged
every two months.
5. The battery and the charger should be stored in a dry and well-ventilated area at an ambient
temperature of 0 – 35°C and a relative humidity of up to 65%. Avoid leaving these devices near
corrosive substances and make sure that they are at a safe distance from excessive heat and
open fire.
6. Protect the e-bike against the weather, particularly the sun, rain and snow.
7. Store the e-bike in a dry and dark room and protect it against dust.
DISPOSAL OF THE EE-BIKE AT THE END OF ITS SERVICE LIFE
Protect the environment! Electrical devices and batteries must not be disposed of in communal
waste. This product and its batteries contains electric/electronic components. According to
European Guideline No. 2012/19/EU, electric and electronic devices and batteries must not be
disposed of in communal waste when they reach the end of their service life, but must be taken
to specified collection sites for ecological disposal. You can obtain information about these sites
from the municipal authority.

E-BIKE WARRANTY
Warranty conditions
The MTF retailer will repair all defects caused by defective material, execution, design or assembly
which occur during the warranty period at its own expense. The warranty does not apply to damage
caused by accidents, overloading the frame or wheels, incorrect use, operation or maintenance, incorrect
storage or unprofessional repairs.
Claims procedure
Always apply a claim against the e-bike or battery through your retailer.
During application of the claim, submit the purchase document, or the warranty certificate with the
serial number of the frame or battery filled in, and give the reason for the claim and a precise description
of the defect.
Warranty period
defects and material defects,
defects, apart
24 months for e-bike components. This applies to manufacturing defect
from normal wear and use.
use
6 months for the battery service life. The nominal capacity of the battery will not fall below 70% of total
capacity over a period of 6 months from sale of the e-bike.
bike.
General terms of use
Every user of the bicycle is liable for any damage or harm caused by incorrect use of the bicycle and
its components. Before riding the bicycle always carefully check the frame and all its components.
Warranty terms
This product must be used exclusively for the purpose for which it was manufactured and for which it
is intended. When applying the warranty, the customer will present the complete, clean bike, the
confirmed original of the warranty certificate and the sales document (receipt).
Claims are always of the nature of a removable defect, which is dealt with by replacement of the
component, repairs or professional adjustment. Repairs ensure that the customer may continue using the
product duly and without restriction.
The right to apply the warranty expires if:
•
•
•
•
•
It was found that the damage to the product was not caused by the manufacturer, but the user
(inappropriate repairs, extreme load, incorrect storage, etc.).
Failure to apply a warranty claim during the warranty period.
If the product was not duly used and maintained in compliance with the instructions for use.
If a duly completed warranty certificate and original purchase document (receipt) was not
submitted during application of the claim.
Defects originating as a result of normal wear (e.g., of the chain or rims) or excessive wear
caused by neglecting inspections and maintenance cannot be the subject of a claim.
Warranty terms for individual parts of the e-bike
The warranty for components does not apply to defects caused by the user, failure to follow the
instructions for use, normal wear, use for purposes for which neither the frame nor the components are
intended (professional racing, extreme jumping and other non-standard use). Neither the manufacturer
nor the retailer are liable for any injury caused during use of e-bikes and their components.
Frame and fork
The warranty applies to material, joints and rusting. The warranty cannot be applied for damage
caused by accidents or unprofessional repairs. The original paint on the specific component must be
retained in order to assess the cause of damage.
Suspension fork and rear suspension unit
A key criterion for accepting claims regarding a cracked suspension fork is that the geometry of the
internal and external pistons of the fork is intact. Defects of the nature of origin of play cannot be claimed
if there is dirt or water in the fork, which causes damage, and also bent fork pistons or damaged heads
as a result of accidents or overloading.
EN - 34
Defects during which the geometry of the unit is damaged (accident or overloading or inappropriate
adjustment), or if there is evident leakage of air or oil caused by penetration of dirt and water under the
seal, there are clear grooves or traces of corrosion on the sliding parts, cannot be acknowledged in
relation to the rear suspension.
Steering
The warranty applies to material defects, deformation of the fork arms is not recognised if the stem is
tightened excessively or the stem is deformed after being extended above the mark for maximum
permissible extension. Operation of the bicycle requires control and adjustment of play in the headset,
which is why knocked out, corroded or dirty bearing tracks cannot be acknowledged as a justified claim.
Bottom bracket
Defects of the material and its thermal processing are included in the warranty. Normal adjustment of
play is not covered by warranty. It is also not possible to recognise deformed or stripped threads of
components and damaged crank arm torx sockets. Stripped bearing races and corroded parts are not
covered by warranty. Please regularly check the condition of the bottom bracket and react appropriately
to any potential origin of noticeable play immediately.
Pedals
The warranty applies to provable material defects. Wear as a result of use, loosening or cracking of
frame joints or bending of pins caused by impact are not a reason to recognise a claim. Generation of
sound and adjustment of play are not covered by warranty, but post-warranty servicing. Be careful of the
moving parts of pedals becoming loose, check that these are correctly tightened. The warranty does not
apply to loss of loose parts.
Wheels
The warranty covers material defects (cracked rim, hub, sprocket, axle) including defects of surface
treatment. A key criterion for accepting a warranty claim on the basis of operating play and noise
generated by the running of the sprocket is functionality. Stripped bearing races, penetration of dirt into
the freewheel element and hub bearings and corroded parts are not covered by warranty.
Brakes, gear shift mechanism, front and rear derailleurs
The warranty covers material defects. The warranty does not apply to adjustment. Adjustment may
change as a result of storage, manipulation and cycling and repeated adjustment is part of normal
bicycle maintenance. Shifting gears, particularly using the front derailleur levers, requires some
sensitivity. The warranty cannot be applied to potential stripping of the mechanism as a result of use of
inappropriate force.
Saddle, seat post
The warranty covers material defects and the defect is assessed from the aspect of impact on
function. A claim cannot be applied on the basis of grooves caused by moving the seat post in the saddle
tube. Claims on the basis of the seat post are not recognised if it was extended past the mark of
maximum permissible extension. Claims also cannot be applied against bent seat posts as a result of
accident or overloading when jumping, bending of the saddle rails, damage to the cable guide of
telescopic seat posts in the saddle tube, torn saddle covers, etc.
Chain
The warranty covers material defects (e.g., broken links). The warranty does not apply to wear as a
result of normal use. The warranty does not apply to broken chains as a result of insensitive gear shifting
(disconnection at the pin), deformation as a result of operation (overturning), operating wear (chain
stretch, so-called maximum permissible spacing between the links) and if maintenance is neglected
(corrosion, jamming due to dirt, etc.).
Reflectors, chainset cover, spoke cover
The warranty applies to material defects. Fractured or broken parts are not covered by warranty.
Disc and hydraulic brakes
The warranty applies to manufacturing and material defects. The warranty cannot be applied to
damage caused by accidents, neglected maintenance or unprofessional repairs. In the case of hydraulic
brakes, always use hydraulic brake fluid recommended by the manufacturer. The properties of brake
fluid differ so much that use of incorrect fluid can cause serious damage to the entire brake system.
