Operating your Bosch drive unit
Safety instructions
Read and understand all safety warn-
ings and instructions. Failure to follow
the below warnings could result in death
or serious injury.
Save all safety warnings and instructions for fu-
ture reference.
The term battery pack used in these operating in-
structions refers to all original Bosch eBike battery
packs.
Do not attempt to change – in particular, to in-
u
crease – the power of your drive or the maxi-
mum speed that it supports. Doing this may put
yourself and others at risk, and you could also
breach statutory regulations.
Do not open the drive unit yourself. The drive
u
unit must only be repaired by qualified person-
nel using only original spare parts. This will en-
sure that the safety of the drive unit is maintained.
Unauthorized opening of the drive unit will render
warranty claims null and void.
All components fitted to the drive unit and all
u
other components of the eBike drive (e.g. chain-
ring, chainring receptacle, pedals) must only be
replaced with identical components or compo-
nents that have been specifically approved by
the manufacturer for your eBike. This will protect
the drive unit from overloading and becoming dam-
aged.
Remove the battery from the eBike before be-
u
ginning work (e.g. inspection, repair, assembly,
maintenance, work on the chain, etc.) on the
eBike, transporting it with a car or airplane, or
storing it. Unintentional activation of the eBike sys-
tem poses a risk of injury.
Bosch eBike Systems
The eBike system can be activated by pushing
u
the eBike backwards or by turning the pedals
backwards.
The push assistance function must only be used
u
when 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 ped-
u
als may turn at the same time. When the push as-
sistance function 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
u
hands or legs to come into contact with the hous-
ing of the drive unit. Under extreme conditions,
such as continuously high torques at low travel
speeds, or when riding up hills or carrying loads,
very high temperatures may be reached on the
housing.
The temperatures that may be reached on the drive
unit housing are influenced by the following factors:
– Ambient temperature
– Ride profile (route/gradient)
– Ride duration
– Assistance modes
– User behavior (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
Use only original Bosch batteries that the manu-
u
facturer has approved for your eBike. Using
other batteries can lead to injuries and pose a fire
hazard. Bosch accepts no liability or warranty
claims if other batteries are used.
Do not make any modifications to your eBike
u
system or fit any other products that might in-
crease the performance of your eBike system.
