1 Safety
The User Manual contains the following symbols that
denote dangers or important information. Read all the
safety information. Failure to observe the instructions can
cause electric shock, re and/or serious injury.
WARNING
regarding possible physical injury, increased
risk of falls or other injuries.
IMPORTANT ADDITIONAL INFORMATION
or special information on using the Pedelec.
NOTE
regarding possible damage to property or the
environment.
1.1 General
If risk-ee operation of your Pedelec cannot be
assumed, take it out of operation and make sure
it cannot be used until you have it checked by a
specialist cycle shop. Risk-ee use is no longer
possible if live parts or the battery shows signs of
damage.
Never ride with no hands! This poses an acute risk
of falling.
Take the battery out of the Pedelec before begin-
ning work on the Pedelec.
Observe the maximum permitted gross weight
of your Pedelec, as this could otherwise lead to
breakage or failure of safety-relevant components

Chapter 11 “Technical data”.
If you wish to make any adjustments to the ride
characteristics of your Pedelec, please consult
your specialist cycle shop.
1.2 Statutory requirements
The Pedelec, like all other bikes, must comply with
the national regulations for road safety. Please
observe the relevant explanations and general
information provided in the “Original User Manual
| General” (CD).
These statutory requirements apply for a Pedelec:
•The motor is designed only to provide pedal-
ling assistance, i.e. it can only “assist” the rider
when he/she turns the pedals.
•The average motor output must not exceed
250W.
•As the speed increases, the rate at which the
motor output reduces must also increase more
intensely.
•The motor must switch o once the bike reaches
a speed of 25 km/h.
1.2.1 Meaning for the rider
•You do not legally have to wear a helmet. Howev-
er, in the interest of your own safety, you should
never ride without a helmet.
•You do not legally have to have a driving licence.
•You do not legally have to have insurance.
•No age restriction applies for a Pedelec.

Original User Manual | Pedelec Impulse 2.0 5
•The regulations governing the use of cycle paths
are the same as for normal bikes.
These regulations apply to you wherever you are
in the European Union. It is possible that dierent
regulations exist in other countries, also inside
the EU in individual cases. Before using your Pe-
delec abroad, nd out about the applicable legis-
lation in the relevant country.
It is generally permitted for children to be carried
in bike trailers on Pedelecs. Observe the maximum
permitted gross weight of the bike

Chapter 30
“Technical data” of the “Original User Manual |
General” (CD). The Impulse 2.0 mountain bike is
an exception. Bike trailers may not be used on this
bike.
1.3 Battery
The battery contains chemical substances, which
could cause dangerous reactions if the safety
information given here is not adhered to.
Avoid contact with liquid leaking om a damaged
battery. In case of contact, rinse o the liquid with
water. In case of eye contact, consult a doctor
aer rinsing.
Never attempt to repair your battery. Batteries
must not be dismantled, opened or crushed. The
improper opening or destruction of the battery
poses the risk of serious injury. Opening the bat-
tery voids the warranty claim. If your battery is
damaged, contact your specialist cycle shop. The
specialists here will discuss the next steps with
you.
A battery must not be exposed to heat (e.g. heat-
er) or re. External heat can cause the battery to
explode. In addition, high temperatures shorten
battery service life. When charging, always ensure
there is adequate ventilation.
A battery must not be short-circuited. Batteries
must not be stored unsafely in a box or compart-
ment where they can short-circuit one another
or can be short-circuited by other conductive
materials (paper clips, coins, keys, nails, screws).
A short circuit between the battery contacts can
cause burns or re. Short-circuit damage which
emerges in this context voids all guarantee claims.
Batteries must not be exposed to mechanical
shocks. Even if a battery shows no visible signs
of damage aer falling or being knocked, it may
be damaged. For this reason, even batteries that
seem ne must be taken to a specialist dealer for
inspection. Damaged batteries must neither be
charged nor used for another application.
Keep the battery away om children.
Use the battery solely for your Pedelec.
Ideally, take the battery out of your Pedelec when
not in use.
Batteries not designed for use in the Pedelec must
not be used.
Never transport damaged batteries. The safety of
damaged batteries cannot be guaranteed.
Lithium reacts very strongly upon direct contact
with water. Never put the battery into water. Cau-
tion is therefore also required in the case of dam-
aged batteries which have become wet: They may
catch re.
In case of re, water should be used to extinguish
any ames in the immediate vicinity, but not the
battery itself. Fire extinguishers with metal re
powder (Class D) are better suited to this task. If
the battery can be safely moved outdoors, the re
can also be suocated using sand.

6 Original User Manual | Pedelec Impulse 2.0
The Pedelec operates using extra-low voltage
(36volts). Never attempt to operate the Pedelec
using power om a source other than a suitable
genuine battery. The designations of approved
batteries are listed in

Chapter 11 “Technical
data”.
1.4 Charger
The charger may only be used to charge the bat-
tery supplied. Use of the charger for other pur-
poses is not permitted. Any kind of manipulation
of the charger or battery housing is forbidden!
The mains voltage must correspond to the voltage
given on the type plate of the charger. The supply
voltage of the charger is given on the type plate on
the back of the device.
The charger is only intended for use indoors. The
battery may only be charged in a dry, non-amma-
ble environment. During the charging process, the
battery and charger must be placed on an even,
non-ammable surface. Battery and charger must
not be covered. There must be no highly combus-
tible materials in the immediate vicinity. This also
applies when charging the battery on the Pedelec.
In this case, you must place the Pedelec so as to
prevent any re om spreading quickly (exercise
caution with carpeted oors!).
Ingress of water and damp in the charger must
be avoided at all costs. In case of ingress of wa-
ter, immediately disconnect the charger om the
mains and have it checked by a specialist.
The battery may heat up during charging. A maxi-
mum temperature of 45°C may be reached. If the
battery becomes any warmer than this, suspend
the charging process immediately. Such a battery
may no longer be used, and you must have it in-
spected by the dealer.
A battery that displays a fault may not be charged
anymore.
The battery should not be le unattended while
charging. Alternatively, charge the battery in a
metal box.
Damaged batteries must not be charged (risk of
explosion!).
Do not attempt to modi or take apart the charger.
Have repairs carried out only by specialists.
A charger with a damaged mains plug or mains
cable may not be connected to the mains and must
be replaced by a specialist. The same applies for
extension cables that are not in perfect technical
condition.
Do not charge batteries for an extended period if
they will not be used.
If you detect smoke or an unusual smell, immedi-
ately unplug the plug of the charger om the sock-
et and disconnect the battery om the charger.
No chargers other than those specically intended
for use with the battery may be used. The use of a
dierent charger may cause malnctions, short-
ened service life, re or explosion.
Do not continue to use damaged batteries and
chargers (plug, housing, cable).
Do not replace the mains cable. This poses the risk
of re and explosion.
Condensation may form on the charger if the
temperature changes suddenly om cold to hot.
In case of condensation, wait approximately one
hour before connecting the charger to the mains,
until it has warmed up to the temperature of the
room. Ideally, avoid such situations by storing the
charger in the place where it is operated.
Only charge the battery at ambient temperatures
of between 0°C and 45°C. However, you can max-
imise a battery's service life by charging it at an
ambient temperature of between 10°C and 30°C.

Original User Manual | Pedelec Impulse 2.0 7
1.7 Transportation of the Pedelec
For the transportation of your Pedelec, we recom-
mend removing the battery om the Pedelec and
packaging it separately. A suitable transport con-
tainer can be obtained om your specialist cycle
shop.
1.7.1 The Pedelec and your car
If you transport your Pedelec on a bike rack, ensure that it
is designed for the higher weight of a Pedelec. In order to
relieve the load on the rack and protect the battery om
climatic conditions, it must be transported inside the car.
1.7.2 The Pedelec on trains
In Germany, you can take your Pedelec with you on trains
which are marked with the bike symbol. To do so on
German Intercity (IC) and EuroCity (EC) trains, you must
book a place for your bike in advance. As a rule, you may
not take bikes with you on German Intercity Express (ICE)
trains.
1.7.3 The Pedelec on aeroplanes
Your Pedelec is generally subject to the policies of the
respective airline concerning bikes. Batteries are subject
to dangerous goods legislation. Therefore, they must not
be carried on passenger planes – neither in the cargo
hold, nor the cabin. Please contact the relevant airline for
detailed information.
1.5 Motor
If children are present, keep a close eye on them,
especially if there is a possibility they could insert
objects into the motor through apertures in the
housing. This poses the danger of fatal electric
shock.
Bear in mind that the motor can heat up on long
ascents. Be carel not to touch it with your hands,
feet or legs. You could burn yourself.
Live parts may be exposed when you open covers
or remove parts. Connection points may also be
live. Maintenance or repairs on the motor when it
is open must only be carried out by a professional
bike workshop.
1.6 Adjustments/maintenance/repair
When carrying out adjustments and maintenance
or when cleaning, avoid crushing cables or damag-
ing them with sharp edges.
Please have all installation and adjustment work
carried out by your specialist cycle shop. In case
you have to fasten something in place or change
something yourself, you will nd an exhaustive list
at the end of the “Original User Manual | General”
(CD) detailing the tightening torques which must
always be adhered to.

Original User Manual | Pedelec Impulse 2.0 9
3 First steps
3.1 Checking the tightening torques
Check that all screws and important components are fas-
tened securely and correctly. You will nd a table with im-
portant screw connections and the prescribed tightening
torques in

Chapter 30 “Technical data” of the “Original
User Manual | General” (CD).
3.2 Fitting the pedals
It may be that the pedals for your Pedelec have yet to be
tted on delivery:
The right pedal (marked with an “R”) is screwed clockwise
into the right crank arm. The le pedal (marked with an
“L”) is screwed anticlockwise into the le crank arm. Both
pedals are screwed in tightly in the direction of the ont
wheel using a size15 open-ended spanner or a suitable
Allen key. The tightening torque is 40Nm.
If the pedals are not screwed in straight, the
thread in the crank arm may be severely damaged.
This could lead to serious accidents and injuries.
3.3 Adjusting the saddle height
3.3.1 Clamping screw
If a torque is specied (in Nm) on the seatpost clamp,
tighten the clamping screw according to this value. If no
tightening torque is specied, tighten an M6 screw (dia.
6mm) and an M5 screw (dia. 5mm) to 5.5Nm.
3.3.2 Quick-release device
For opening, the quick-release lever must be folded back
through 180° – you will see the lettering “OPEN”. For clos-
ing, fold the quick-release lever back in through 180° –
you will see the lettering “CLOSE”.
Opening the quick-release lever
OPEN
Closing the quick-release lever
CLOSE
As a rule of thumb, you can be condent that the
quick-release device clamp is suciently secure
if the quick-release lever can only be closed us-
ing the heel of the hand and a certain level of
force. During the closing process, you will feel
an increasing level of counterpressure om the
lever, beginning when the lever is at approx. 90°.
If the seatpost is not clamped rmly or securely
enough, tighten the clamping nut or turn the screw
clockwise by another half a turn respectively while
the quick-release lever is open. Close the quick-
release lever and check that the saddle is securely
fastened once more.
Check that all quick-release levers are fastened
correctly and securely before every journey and
every time you return to your bike having le it
unattended for a short time.
With regard to the saddle height, there is a sim-
ple test procedure: Whilst sitting on the saddle,
the heel of your lly-stretched leg should reach
the lowest pedal position. By contrast, the balls
of your feet should reach the centre of the pedal
in the lowest pedal position with your leg bent
slightly.

assistance.
5 Battery
Your battery is a lithium-ion battery, the ideal type of bat-
tery for this application. One of the main benets of this
battery is its low weight combined with a high capacity.
5.1 Charging the battery
You can charge the battery whilst it is on the Pedelec

Chapter 4 “Quick start”.
Alternatively, you can take the battery out of its holder
and charge it in a separate location. This is recommended
if it is cold outside, in order to charge the battery in a
warmer room.
Condensation may form on the charger if the
temperature changes suddenly om cold to hot.
In case of condensation, wait approximately one
hour before connecting the charger to the mains,
until it has warmed up to the temperature of the
room. Ideally, avoid such situations by storing the
charger in the place where it is operated.
The battery can be charged at temperatures between 0°C
and 45°C. However, you can maximise a battery's service
life by charging it at an ambient temperature of between
10°C and 30°C.

your charger has an LED, this lights up red. The bat-
tery is charged in ve stages. When charging of one

Original User Manual | Pedelec Impulse 2.0 13
stage is in progress, the corresponding LED ashes.
If this stage has been lly charged, the LED will light
up permanently. Now the next LED will begin to ash.
Aer all ve LEDs have gone out, the battery is lly
charged.
b) Seat tube battery: The charging process begins.
The LED of the charger lights up in green. The battery
LEDs light up one by one to indicate the progress of
the charging operation. The battery is charged in ve
stages. When charging of one stage is in progress, the
corresponding LED ashes. If this stage has been lly
charged, the LED will light up permanently. Now the
next LED will begin to ash. Aer all ve LEDs have
gone out, the battery is lly charged.
If your charger has an LED, it may be that this
ashes red permanently. If this is the case, a
charging fault has occurred. Have the charger and
battery checked by your specialist cycle shop.
4. Pull the charger plug out of the socket once the charg-
ing operation is complete.
Damaged batteries may not be charged, and r-
ther use is not permitted.
The battery may heat up during charging. A maxi-
mum temperature of 45°C may be reached. If the
battery becomes any warmer than this, suspend
the charging process immediately.
There is no memory eect. You can therefore lly
recharge your battery aer every trip so you are
always ready for the o.
Ideally you should charge the battery at a temper-
ature of between +10°C and +30°C. It takes longer
to charge the battery at low temperatures, while
the battery will not charge up at temperatures
higher than +45°C. Ideally, you should charge and
store the battery inside your house or in a warm
garage when the outside temperature is low. In
this case, you should only t the battery onto your
bike just before using it.
5.1.3 Installing the battery
1. a) Down tube battery: Insert the battery into the bat-
tery holder of the Pedelec om the ont/above. At the

The range of the battery is less in winter due to
the lower temperatures. Only move the battery
om the warm room where you store it and t it
on your Pedelec just before you set o. This will
help to prevent the eect of the low temperature
on the range of the battery.

Chapter 5.4 “War-
ranty and service life”.
5.3 Battery management
The battery management monitors the temperature of
your battery and warns you of incorrect use.
If an external short-circuit has been caused at the
contacts or the charging socket, please consult
your specialist cycle shop.
Please always supervise the battery charging pro-
cess and disconnect the charger aerwards.
5.3.1 Sleep mode
The battery management switches the battery to sleep
mode to prevent a so-called total discharge. At the latest,
the battery management activates the sleep mode aer
ten days without use. The system exits sleep mode when
you connect the battery to the charger or press the battery
key or push button on the battery. This “wakes up” the
battery.
Down tube battery: If the battery does not wake
up, the cell voltage may be too low. In this case,
connect up the charger and press the battery key.
The battery is charged for one minute.
Seat tube battery: The battery can also be put into
sleep mode manually. To do so, press the push
button for eight seconds. Release the push button
as soon as the second LED lights up.
5.4 Warranty and service life
Batteries are wear parts. Wear parts come with a two-year
warranty.
If a fault occurs during this period, your specialist cycle
shop will replace the battery. Normal ageing and battery
wear do not constitute a fault.
The service life of the battery depends on dierent factors.
The most important wear-relevant factors are:
•The number of charging processes
Aer 1,100 charging cycles, your battery will still
have 60% of its initial capacity, providing it has
been well looked aer. This means 6.6 Ah in an 11
Ah battery and 7.2 Ah in a 15.5 Ah battery. A charg-
ing cycle is dened as the sum of the individual
charges until the charges reach the overall capacity
of the battery.
For example: You charge the battery with 5 Ah on
the rst day, 2 Ah on the second day and 4 Ah on
the third day; the sum is 11 Ah. The battery has
thereby completed one charge cycle.
According to the technical denition, the battery
is exhausted when less than 60% of the initial
capacity is available. Providing you can still cover
the journey distances with the remaining battery
capacity, you can of course continue using it. If the
capacity is no longer sucient, you can take your
battery to a specialist cycle shop who will dispose
of your battery and sell you a new one.
•The age of the battery
A battery also ages during storage.
This means: Even if you do not use your battery, its
capacity reduces. You can expect the battery to age
by approximately 3 to 5%.
Ensure that the battery does not become too
hot. The rate at which the battery ages increases
signicantly at temperatures above 40°C. Direct
sunlight can heat the battery considerably. Be sure
not to leave the battery in a hot car and always
stand your Pedelec in the shade during breaks in
cycle trips. If you cannot prevent exposure to heat,
please ensure that the battery is not charged dur-
ing this period.

16 Original User Manual | Pedelec Impulse 2.0
A lly charged battery ages at an even greater rate
than a partially charged one at high temperatures.
•If you always ride with maximum motor output,
your motor will always require a stronger cur-
rent. Stronger currents cause the battery to age
more quickly.
•You can also extend the service life of the bat-
tery by using the assistance selectively. Use a
low assist level when riding. With lower dis-
charge currents, you conserve your battery.
Make sure that the battery is lly charged before
you ride your bike for the rst time or if you have
not used it for a while.
5.5 Storage
If you do not need your battery for a while, store it at a
temperature of 18–23°C at 50–70% of its ll charge
capacity. If you do not use the battery for six months, you
must recharge it.
5.6 Shipping
Do not ship batteries! A battery is a hazardous
article which can overheat and catch re in certain
conditions.
The preparation and shipping of a battery may only be
carried out by trained personnel.
If you would like to return your battery for replacement,
please always arrange this via your specialist cycle shop.
Specialist cycle shops can have the battery picked up
ee of charge and in compliance with dangerous goods
legislation.
5.7 Disposal
Batteries are not to be disposed of with domestic waste.
Consumers are legally bound to dispose of used or dam-
aged batteries at the locations designated for the purpose
(battery collection point or specialist cycle shop). The
disposal of batteries is clearly regulated in each country's
laws.
6 Charger
If used incorrectly, the device may be damaged or
inict injuries.
•Only use the charger in dry rooms.
•Only place the charger in a secure stable position
on a suitable surface.
•Do not cover the charger or place any objects on
it as otherwise it could overheat and catch re.
Do not use other chargers. Only charge the battery
using the charger provided, or a charger approved
by us for the purpose.
Read the type plates on the charger before using it
for the rst time.
You can charge your Pedelec Impulse 2.0 directly via a
charging socket in the battery. The battery can remain on
the Pedelec whilst the charging operation is in progress.

SEAT TUBE BATTERY
Alternatively, you can take the battery out of its holder
and charge it elsewhere. This is recommended if it is cold
outside, in order to charge the battery in a warmer room.
