Operating your Bosch Drive Unit

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.
Read and observe the safety warnings and in-
u
structions in all operating instructions of the
eBike system and your eBike.
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 make any modifications to your eBike
u
system or fit any other products that might in-
crease the performance 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 pur-
chased. 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 accidents that can be attributed to manip-
ulation of the bicycle.
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-

Safety instructions

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
system poses a risk of injury.
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.
When using the push assistance, ensure that
u
you can always control the eBike and hold it se-
curely. The push assistance can be suspended un-
der certain conditions (e.g. obstacle on the pedal
or accidentally slipping off the button of the operat-
ing unit). The eBike can suddenly move backwards
towards you or start to tip. This poses a particular
risk for the user if there is an additional load. When
using the push assistance on the eBike, do not
place the eBike in situations in which you cannot
hold the eBike by yourself.
Under extreme conditions, such as con-
tinuously high loads at low speed when
riding up hills or carrying loads, parts of
the drive unit can reach temperatures
in excess of 140 °F.
