V.II E-mountain bike
This bike is not designed and equipped for use on public roads. Before it
canbeusedonpublicroadsitmustbettedwiththelegallyprescribed
equipment.Itisdesignedtobeusedo-road,butnotforcompetitions.
The manufacturer and dealer accept no liability for damage resulting from
anyusebeyondthisdenitionand/orfailuretocomplywiththesafety
information and instructions in the user guide. This applies particularly
to the use of this bike in competitions, overloading and the failure to
properly rectify faults. Intended use also includes conformance with
thespeciedoperating,serviceandrepairconditionsintheuserguides
and service book 13. Service intervals, Page US-99. Fluctuations in the
consumption and power of the battery and a reduction of capacity with
increasing age 7.3.1.2 Capacity, Page US-73 are common and technically
unavoidable, and as such, do not constitute material defects.
V.III Pedelec weight
Forsafetyreasonswerecommendyouweighyourpedelec
because the weight can vary due to various equipment
characteristics, accessories and frame heights, otherwise
you risk fracturing the frame. This can lead to severe falls
that could result in death or serious injury.
V.IV The maximum permissible total weight
WARNING
Do not exceed the the maximum permissible total weight of the
pedelec, because it can lead to the fracture or failure of safety-
relevant parts (such as the brakes). If this happens while you are
riding the bike, it can lead to severe falls – with fatal consequences.
Total weight = Weight of the bike + weight of the rider + weight of the
trailer bike or trailer + weight of luggage and/or child.
Example calculation:
259 lbs total weight = 61 lbs weight of the bike + 165 lbs weight of
the rider + 22 lbs weight of the trailer + 11 lbs weight of the luggage.
259 lbs is below the allowed total weight of 287 lbs and is therefore
permissible.
Bike type Maximum permissible total weight Weight of rider**
Impulse Evo pedelec 287 lbs 225 lbs
** with a 61 lbs pedelec.

maintenance of your bike reduces risk of injury.
We discourage allowing children under the age of 16 years to ride
pedelecs. They may not be able to cope with the speed. It can result in
serious accidents and falls.
Wear a bike helmet. You should always wear a suitable bike helmet for
your own safety. A bike helmet can protect you from severe injuries.
Make sure the helmet is correctly positioned.
Do not ride in unfavorable lighting conditions (fog, rain, dusk, dark-
ness) without adequate lighting IV.II Lighting, Page US-8; it can
lead to accidents and serious injuries 1.1.2 Wet weather, Page
US-17. Avoid wet weather riding where possible.
Keep your hands and other body parts and clothing away from moving
parts. They may get caught or entangled and lead to a fall and/or
other serious injuries.

Inspect your pedelec before every trip, and after each time it has been
transported anywhere or has been left unattended 4. Before every
trip, Page US-40. If wear and damage are not detected in good time,
components may fail. If this happens while you are riding the bike
you could be severely injured or killed. Due to the additional power,
wearing parts on a pedelec are subject to more stress than a normal
bike. If you observe worn, damaged or bent components do not use
the bike again until the components are repaired or replaced.
Contact your bike dealer when it is necessary to replace wearing parts
and other 13. Service intervals, Page US-99 components. We recom-
mend that all assembly and adjustment work is carried out by your
dealer. Only use original replacement parts. Replacement parts from
other manufacturers can impair the function of your pedelec. It can
result in failures that can lead to serious accidents, injury or death.
WARNING
Do not exceed the the maximum permissible total weight of the
pedelec, because it can to the fracture or failure of safety-relevant
parts V.IV The maximum permissible total weight, Page US-10. If this
happens while you are riding the bike, it can lead to severe falls –
with fatal consequences.
Ask your dealer to show you the operation and features of the
components. Please also read the component guides. We recommend
that all assembly and adjustment work be carried out by an approved
dealer, as incorrect assembly could cause components to become
loose. If this happens while you are riding the bike you could be
severely injured or killed. If you do have to tighten something, you

Always remove the battery before starting to do adjustments,
assembly, service or maintenance on the pedelec. The pedelec could
switch on unexpectedly and you could be seriously injured.
You should have your bike and its components checked periodically by
your dealer for indicators of stress and/or potential failure, including
cracks, deformation, corrosion, paint peeling, dents, and any other
indicators of potential problems, inappropriate use or abuse. These
are important safety checks and very important to help prevent
accidents, bodily injury to the rider and shortened product life.

1.1 Tips
1.1.1 Children
WARNING
Make sure that your child always wears an approved bike helmet when
riding; but also make sure that your child understands that a bike
helmet is for bicycling only, and must be removed when not riding. A
helmet must not be worn while playing, in play areas, on playground
equipment, while climbing trees, or at any time while not riding a
bike. Failure to follow this warning could result in serious injury or
death.
As a parent or guardian, you are responsible for the activities and safety of
your minor child, and that includes making sure that the bike is properly
ttedtothechild;thatitisingoodrepairandsafeoperatingcondition;
that you and your child have learned and understand the safe operation of
the bike; and that you and your child have learned, understand and obey
notonlytheapplicablelocalmotorvehicle,bikeandtraclaws,butalso
the common sense rules of safe and responsible bicycling. As a parent,
you should read this manual, as well as review its warnings and the bike’s
functions and operating procedures with your child, before letting your
child ride the bike.
CAUTION
Do not attempt to open the motor, display, battery or charger;
you could injure yourself. Furthermore, parts may be destroyed,
invalidating the warranty. If problems arise please contact your
dealer.
NOTICE
Always park your pedelec so that it cannot tip over. If the bike tips
over components can be damaged. If your bike is not equipped with a
kickstand,onecanberetrotted.Pleaseaskyourdealer.
Do not clean the pedelec with a water hose or high pressure washer.
You could damage the bike. Clean the pedelec with a soft damp cloth.

1.1.2 Wet weather
WARNING
Avoid wet weather riding where possible. Wet weather impairs
traction, braking and visibility, both for the bicyclist and for other
vehicles sharing the road. The risk of an accident is increased in
wet conditions. Under wet conditions, the stopping power of your
brakes (as well as the brakes of other vehicles sharing the road) is
dramatically reduced and your tires don’t grip nearly as well. This
makes it harder to control speed and easier to lose control. To make
sure that you can slow down and stop safely in wet conditions, ride
more slowly and apply your brakes earlier and more gradually than
you would under normal, dry conditions.
1.1.3 Night rides
Riding a bike at night is much more dangerous than riding during the day.
Abikerisverydicultformotoristsandpedestrianstosee.
WARNING
Therefore, children should never ride at dawn, at dusk or at night.
Adults who chose to accept the greatly increased risk of riding at
dawn, at dusk or at night need to take extra care both riding and
choosing specialized equipment which helps reduce that risk. Consult
your dealer about night riding safety equipment.

2. Protection from theft, manipulation and loss
WARNING
Protectyourpedelecfromunauthorizedaccess.If third parties alter
components (e.g. the brakes) without your knowledge, you could
be seriously injured. Inspect your pedelec before every trip, and
after each time it has been transported anywhere or has been left
unattended 4. Before every trip, Page US-40.If your bike is damaged,
donotrideitagainbeforethedamagehasbeenrectied.Ifyourbike
is lost or stolen it will not be replaced under the warranty.
The following measures can help you to protect your pedelec from theft
and manipulation and to recover it if it has been stolen:
Always lock the bike and battery even if you are only leaving
it for a short while. Ideally, the lock(s) should block the
wheel powered by the motor. Do not leave the key in. To
be on the safe side, you can also remove the battery. The
pedelec must also be secured with a lock when it is parked
outside the home (e.g. sheds, basement).
Do not park your pedelec in deserted locations – especially
for long periods. If possible, park your pedelec in manned
private or communal garages or individual bike lockers.

Always wear appropriate shoes that will stay on your feet
and grip the pedals. Make sure that shoe laces do not
get entangled or caught in moving parts, and never ride
barefoot or in sandals.
Always wear protective eyewear, to protect against airborne
dirt, dust and bugs — tinted when the sun is bright, clear
when it’s not.

Quick-releasewheelsshouldbeattachedtoaxedobject
together with the frame. That way the bike cannot be stolen.
Alternatively, the quick-release levers can be replaced by
an anti-theft device. For questions about this please contact
your dealer.
Use a high quality bike lock: you should invest approximately
10% of the purchase price of the bike in locks. Your dealer
willbeabletotasuitableframelockifyourbikedoesnot
already have one. Alternatively, you can also use other types
of bike locks. Ask your dealer for advice.
Make a note of the important details of your pedelec
and get it registered with the police. This makes it easier to
identify if it is stolen.
Bike theft is often covered by household contents insurance.
Check the terms of your insurance policy as soon as
possible.
3. Beforeyourrstride
Make sure that your pedelec is adjusted to suit your height and is ready to
use. Familiarize yourself with the basic functions of your pedelec. If your
newbikedoesn’tt,askyourdealertoexchangeitbeforeyourideit.
WARNING
Your dealer will explain to you the operation and specificities of your
pedelec and its components. Please also read the component guides.
We recommend that all assembly and adjustment work is carried out
by a dealer, as incorrect assembly could cause components to become
loose. If that happens while you are riding the bike you could be
severely injured or killed. If you do have to tighten something, you
will find a complete list of the required torque settings in Section
12. Torque settings, Page US-97, which must be strictly followed.

3.1 Attaching the pedals
1. Screw the right hand pedal (marked 'R') into the right hand pedal
crank in a clockwise direction.
2. Screw the left hand pedal (marked 'L') into the right hand pedal crank
in a anticlockwise direction.
WARNING
Make sure you screw the pedals in straight otherwise you could
damage the thread on the pedal crank – if that happens while you are
ridingthebikeyoucouldfallo.
3. Tighten both pedals towards the front wheel with a torque setting of
40 Nm [29.5 ft·lb].
3.2 Adjusting the saddle
Correct saddle adjustment is an important factor in getting the most
performance and comfort from your bike. If the saddle position is not
comfortable for you, see your dealer. Your dealer can adjust saddle angle
or teach you how to do it.
CAUTION
Some people have claimed that extended riding with a saddle which
is incorrectly adjusted or which does not support your pelvic area
correctly can cause short-term or long-term injury to nerves and blood
vessels, or even impotence. If your saddle causes you pain, numbness
or other discomfort, listen to your body and stop riding until you see
yourdealeraboutsaddleadjustmentoradierentsaddle.Ifyouhave
questions, please consult with a urologist or men’s health expert.
3.1.1 Toe overlap
WARNING
Avoid toe overlap (picture a). Otherwise, your foot can get caught in
the spokes, you can fall very hard and get serious injuries. Your toe or
toeclip may be able to contact the front wheel when a pedal is all the
way forward and the wheel is turned. Changing tire size or pedal crank
