1. SAFETY
In this manual you will nd the following
symbols that draw attention to hazards or
important information.
1.1 GE NER AL
Take care when children are
around, especially if they are able
to insert objects through apertures in
the motor housing. There is a risk of a
life-threatening electric shock.
If you think the bike is no longer safe to
use, you must take it out of use at once,
secure it against unintentional switching
on or use, as the case may be, and make it
available to the dealer for inspection.
It is no longer safe to use if current-car-
rying components or the battery show
visible signs of damage.
The push-assistance function may only be
used when pushing the eBike. Danger of
injury when the wheels of the eBike do not
have ground contact while using the pus-
hassistance function.
Do not make any modications to
your eBike system or t any other
products which would be suitable for
increasing the performance of your eBike
system. This normally reduces the lifetime
of the system and risks damage to the drive
unit and the bike. There is also a risk of
losing the guarantee and warranty claims
on the bike you have purchased. By hand-
ling the system improperly you are also
endangering your safety and that of other
road users, thus running the risk of high
personal liability costs and possibly even
criminal prosecution in the event of
accidents attributable to manipulation.
1.2 LEGAL REQUIREMENTS
Like all cycles, the bike must comply
with the requirements of the national
highway code. The legal requirements set
out below are applicable to the bike:
■The motor may only be used to assist
pedalling, i.e. it must only “help” when
the bike user applies eort to the pedals
him or herself.
■The average motor power rating must
not exceed 250 W. As speed increases
motor power must continue to drop
progressively.
WARNING
about potential injury,
increased fall or other
injury risk.
REFERENCE
to potential damage to
property or the environment.
IMPORTANT SUPPLEMEN-
TARY INFORMATION
or special information
about the use of the bike.

page 36.
1.2.1 Signicance for the user
There is no obligation to wear a hel-
met. However for your own safety we
advise you not to cycle without a helmet.
A separate driving licence is not required
for an electric bike. Insurance is not requi-
red for an electric bike.
There is no age restriction on using an
electric bike.
Cycling on cycle tracks is regulated in the
same way as for conventional bikes.
These regulations apply to your bike when
using it within the European Union. Other
provisions may apply in countries outside
the EU and in isolated cases in Europe as
well. Before using your bike abroad be sure
to make enquiries about which laws apply.
1.2.2 Safety and warranty

ger usable to an authorised bicycle dealer.
1.3 BATTERY
• Remove the battery pack from the
eBike before beginning work (e.g.
assembly, maintenance, work on the chain,
etc.) on the eBike, transporting it by car or
plane, or storing it. Unintentional activation
of the eBike system poses a risk of injury.
• Do not open the battery pack. Danger of
short-circuiting. Opening the battery pack
voids any and all warranty claims.
• Protect the battery pack against heat
(e.g., also against continuous intense
sunlight), re and immersing into water.
Danger of explosion.
• Keep the battery pack not being used
away from paper clips, coins, keys, nails,
screws or other small metal objects, that
can make a connection from one terminal
to another. Shorting the battery-pack
terminals together may cause burns or a

7
GAZELLE USER MANUAL BOSCH SYSTEEM
re. For short-circuiting damage caused in
this manner, any and all warranty claims
through Bosch shall be invalid.
• Under abusive conditions, liquid may
be ejected from the battery pack. Avoid
contact. If contact accidentally occurs,
ush with water. If liquid contacts eyes,
additionally seek medical help. Liquid
ejected from the battery pack may cause
skin irritations or burns.
• Battery packs must not be subjected to
mechanical impacts. There is a risk that the
battery pack will be damaged.
• Vapours can escape in case of damage
and improper use of the battery pack. Pro-
vide for fresh air and seek medical attention
in case of complaints. The vapours can
irritate the respiratory system.
• Charge the battery pack only with ori-
ginal Bosch battery chargers. When using
non-original Bosch chargers, the danger
of re cannot be excluded.
• Use the battery pack only together with
eBikes that have an original Bosch eBike
drive system. This is the only way to protect
the battery pack against dangerous
overload.
• Use only original Bosch battery packs
approved for your eBike by the manufactu-
rer. Using other battery packs can lead to
injuries and pose a re hazard. When using
other battery packs, Bosch shall not assume
any liability and warranty.
• Keep the battery pack out of reach of
children.
• Take care not to drop the battery
when removing it from the bike.
This can actually damage the battery
housing irreparably.
• Batteries must not be exposed to mechani-
cal impact. This risks damaging the battery.
• The bike operates at low voltage (36 V).
You must never attempt to use the bike
with a power source other than the original
battery that goes with it. You will nd des-
criptions of permissible batteries in chapter
11 - “Technical specications”.
1.4 CHARGER
• Keep the charger away from rain or
moisture. The penetration of water
into a battery charger increases the risk of
an electric shock.
• Only charge eBike-approved Bosch lithium-
ion battery packs. The battery-pack voltage
must match the battery-pack charging
voltage of the charger. Otherwise there is
danger of re and explosion.
• Keep the battery charger clean. Conta-
mination can lead to danger of an electric
shock.
• Before each use, check the battery char-
ger, cable and plug. If damage is detected,
do not use the battery charger. Never open
the battery charger yourself. Have repairs
performed only by a qualied technician
and only using original spare parts. Dama-
ged battery chargers, cables and plugs
increase the risk of an electric shock.
• Do not operate the battery charger on
easily inammable surfaces (e.g., paper,
textiles, etc.) or surroundings. The heating
of the battery charger during the charging
process can pose a re hazard.
• Vapours can escape in case of damage
and improper use of the battery pack. Pro-
vide for fresh air and seek medical attention
in case of complaints. The vapours can

8
GAZELLE USER MANUAL BOSCH SYSTEEM
irritate the respiratory system.
• Supervise children. This will ensure that
children do not play with the charger.
• Children or persons that owing to their
physical, sensory or mental limitations or
to their lack of experience or knowledge
are not capable of securely operating the
charger, may only use this charger under
supervision or after having been instructed
by a responsible person. Otherwise, there is
danger of operating errors and injuries.
• A short version of important safety warn-
ings in English, French and Spanish with
the following content can be found on the
bottom side of the charger:
■For safe operation see manual. Risk of
electric shock.
■Dry location use only.
■Charge only batteries of the Bosch eBike
Systems. Other batteries may burst
causing personal damage.
■Do not replace the plug assembly as risk
of re or electric shock may result.
1.5 DRIVE UNIT
• Do not open the drive unit yourself.
The drive unit is maintenance-free
and must be repaired only by qualied
experts and only with original spare parts.
This will ensure that the safety of the drive
unit is maintained. Unauthorized opening
of the drive unit will void warranty claims.
• All components mounted to the drive
unit and all other components of the eBike
drive (e.g., the chainwheel, chainwheel seat,
pedals) may be replaced only against
identical components or components
specically approved for your eBike by the
bicycle manufacturer. This protects the
drive unit against overload and damage.
• Remove the battery pack from the eBike
before beginning work (e.g. assembly,
maintenance, work on the chain, etc.) on
the eBike, transporting it by car or plane,
or storing it. Unintentional activation of
the eBike system poses a risk of injury.
• The push-assistance function may only
be used when pushing the eBike. Danger
of injury when the wheels of the eBike do
not have ground contact while using the
push-assistance function.
• Use only original Bosch battery packs
approved for your eBike by the manufactu-
rer. Using other battery packs can lead to
injuries and pose a re hazard. When using
other battery packs, Bosch shall not assume
any liability and warranty.
• Do not make any modications to your
eBike system or t any other products
which would be suitable for increasing the
performance of your eBike system. This
normally reduces the lifetime of the system
and risks damage to the drive unit and the
bike. There is also a risk of losing the gua-
rantee and warranty claims on the bike you
have purchased. By handling the system
improperly you are also endangering your
safety and that of other road users, thus
running the risk of high personal liability
costs and possibly even criminal prosecuti-
on in the event of accidents attributable to
manipulation.
The drive unit is intended exclusively
for your eBike and may not be used
for other purposes.

(especially the battery pack) can become
damaged through extreme temperatures.
1.7 TRANSPORTING THE BIKE
1.7.1 Transporting the bike by car
If you intend to transport your bike
using a cycle carrier, you will also
need to ensure that the carrier is suitable
for the added weight of the bike too. In
order to spare the carrier and protect
the battery against the elements, you are
better transporting the latter in the car.
1.7.2 Transporting the bike by train
You can take your bike in trains displaying a
bike sign. If you have any questions you can
contact the carrier.
1.7.3 Transporting the bike by air

3. Check if the battery pack is tightly
seated. Always lock the battery pack
with lock A6, as otherwise the lock can
open and the battery pack could fall
out of the holder.
4. After locking, always remove the key A5
from the lock A6. This prevents the key
from falling out and the battery pack
from being removed from unauthorized
persons when the eBike is parked.
4.3 CHARGING BATTERY
The battery pack is supplied partially
charged. To ensure full battery pack
capacity, completely charge the battery
pack in the charger before using for the rst
time.
The battery pack can be recharged at any
time on its own or on the bike without
shortening the lifespan. Interrupting the
charging process does not damage the
battery pack. The battery pack is equipped
with a temperature control indicator,
which enables charging only within a
temperature range between 0°C and 40°C.
When the battery pack is not within the
charging-temperature range, three LEDs
of the charge-control indicator A3 ash.
Disconnect the battery pack from the
charger until its temperature has adjusted.
Do not connect the battery pack to the
charger until it has reached the allowable
charging temperature.
At lower temperatures the charging
time becomes longer and battery
capacity is used less eciently thus redu-
cing the range of the battery. When char-
ging at low temperatures we advise you to
charge the battery separately in a warmer
room. Do this by removing the battery from
the carrier, see section 4.1 “Removing the
battery”.
Use only the charger provided with
your eBike or an identical original
Bosch charger. Only this charger is matched
to the lithium-ion battery pack used in your
eBike.

Remove the charger included with the bike
from its packaging and connect the mains
plug to a mains socket (230 to 240 V).
Connect the charger to the battery.
For safe charging the charger
must be placed on a suitable
surface; the substrate must be dry
and non-flammable.
When the battery pack is switched on, the
ve green LEDs of the charge-control indi-
cator A3 indicate the charge condition of
the battery pack. In this, each LED indicates
approx. 20% capacity. When the battery
pack is completely charged, all ve LEDs
light up.
Pull the charger plug out of the mains
socket after charging so as to save power.
You can recharge the battery after
every trip. This means you will always
be ready to use the electric system.
4.4 BATTERY INFORMATION SYSTEM
On the outside of the battery there is an
indicator panel with ve LEDs and an on/
o button. The LEDs will light up as soon as
you press the on/o button. The number of

4.5 BATTERY MANAGEMENT
The battery pack is protected against deep
discharging, overcharging, overheating and
short-circuiting through the “Electronic
Cell Protection (ECP)”. In case of hazardous
situations, a protective circuit automati-
cally switches o the battery pack. When a
defect of the battery pack is detected, two
LEDs of the charge-control indicator A3
ash. In this case, please refer to an
authorized bicycle dealer.
4.6 WARRANTY AND SERVICE LIFE
A two-year warranty applies to the battery.
Should a fault occur during this period, your
Gazelle specialist will replace the battery.
Normal aging as well as wear and tear of
the battery do not constitute a material
deciency.
Take care to ensure that the battery does
not get too hot. Battery aging increases
sharply with temperatures above 40 °C.
Being placed directly in the sun’s rays can
cause a battery to heat up considerably.
Take care to ensure you don’t leave the
battery in a hot car and park your bike in
the shade during bike rides. If you cannot
avoid the heat, make sure you don’t charge
the battery at the same time.
A fully charged battery ages at an even
higher rate at high temperatures than a
partially charged one.
If you ride constantly using maximum
