Safety instructions

Read all the safety information and in-
structions. Failure to observe the safety in-
formation and follow instructions may result
in electric shock, fire and/or serious injury.
Save all safety warnings and instructions for future ref-
erence.
The term battery is used in these instructions to mean all
original Bosch eBike rechargeable battery packs.
Do not open the drive unit yourself. The drive unit
u
must only be repaired by qualified personnel using
only original spare parts. This will ensure that the safety
of the drive unit is maintained. Unauthorised opening of
the drive unit will render warranty claims null and void.
All components fitted to the drive unit and all other
u
components of the eBike drive (e.g. chainring, chain-
ring receptacle, pedals) must only be replaced with
identical components or components that have been
specifically approved by the manufacturer for your
eBike. This will protect the drive unit from overloading
and becoming damaged.
Remove the battery from the eBike before beginning
u
work (e.g. inspection, repair, assembly, maintenance,
work on the chain, etc.) on the eBike, transporting it
with a car or aeroplane, or storing it. Unintentional ac-
tivation of the eBike system poses a risk of injury.
The eBike system can be activated by pushing the
u
eBike backwards or by turning the pedals backwards.
The push assistance function must only be used when
u
pushing the eBike. There is a risk of injury if the wheels
of the eBike are not in contact with the ground while using
the push assistance.
When the push assistance is activated, the pedals may
u
turn at the same time. When the push assistance func-
tion is activated, make sure that there is enough space
between your legs and the turning pedals to avoid the risk
of injury.
After a ride, do not allow your unprotected hands or
u
legs to come into contact with the aluminium housing
of the drive unit. Under extreme conditions, such as con-
tinuously high torques at low travel speeds, or when rid-
ing up hills or carrying loads, very high temperatures may
be reached on the aluminium housing.
The temperatures that may be reached at the drive unit
housing are influenced by the following factors:
– Ambient temperature
– Ride profile (route/gradient)
– Ride duration
– Assistance modes
– User behaviour (personal effort)
– Total weight (rider, eBike, luggage)
– Motor cover on the drive unit
– Heat dissipation properties of the bicycle frame
– Type of drive unit and type of gear-shifting
Bosch eBike Systems
Use only original Bosch batteries that the manufac-
u
turer has approved for your eBike. Using other batter-
ies can lead to injuries and pose a fire hazard. Bosch ac-
cepts no liability or warranty claims if other batteries are
used.
Do not make any modifications to your eBike system
u
or fit any other products that might increase the per-
formance of your eBike system. Doing so will generally
reduce the service life of the system and risks damaging
the drive unit and the bike. You also run the risk of losing
the guarantee and warranty claims on the bicycle 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 prosecution in the event of ac-
cidents that can be attributed to manipulation of the bi-
cycle.
Observe all national regulations which set out the ap-
u
proved use of eBikes.
Read and observe the safety warnings and directions
u
contained in all the eBike system operating instruc-
tions and in the operating instructions of your eBike.
Privacy notice
When you connect the eBike to the Bosch diagnostic tool,
data about the eBike drive unit (e.g. energy consumption,
temperature, etc.) is transferred to Bosch eBike Systems
(Robert Bosch GmbH) for the purposes of product improve-
ment. You can find more information about this on the Bosch
eBike website at www.bosch-ebike.com
