Do not make any kind of modifications to the
u
drive. Do not use any products to increase the
performance of the drive. This will result in you
using an illegal mode of transport in public areas.
Moreover, in doing so, you may endanger yourself
and others; accidents that can be attributed to ma-
nipulation run the risk of high personal liability
costs and possibly even criminal prosecution. In ad-
dition, doing so will generally reduce the service life
of the eBike components. The drive unit and eBike
may be damaged and guarantee and warranty
claims on the eBike you have purchased may con-
sequently be voided.
Do not open the drive unit. The drive unit must
u
be repaired using only original spare parts and
only by an authorized bicycle retailer. This will
ensure that the eBike remains safe to use. Unautho-
rized opening of the drive unit will render warranty
claims null and void.

the eBike. When working on permanently in-
stalled eBike batteries, take particular care to
ensure that the eBike cannot be switched on.
Unintentional activation of the eBike poses a risk of
injury.
Do not remove permanently installed eBike bat-
u
teries yourself. Permanently installed eBike bat-
teries must only be installed and removed by au-
thorized bicycle retailers.
After a ride, do not allow your unprotected
u
hands or legs to come into contact with the
housing of the drive unit. Under extreme condi-
tions, 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 eBike batteries from the
u
system generation the smart system that the
manufacturer has approved for your eBike. Us-
ing other eBike batteries can lead to injuries and
pose a fire hazard. Bosch accepts no liability or
warranty claims if other eBike batteries are used.
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.
