General safety instructions
Read all the safety and general instructions.
Failure to observe the safety and general in-
structions may result in electric shock, fire
and/or serious injury.
Save all safety warnings and instructions for future ref-
erence.
The term eBike battery is used in these instructions to
mean all original Bosch eBike rechargeable battery packs.
The term ABS is used in these instructions to mean all ori-
ginal Bosch eBike anti-lock braking systems.
The ABS function/usefulness will be significantly im-
u
paired if the ABS setting on the eBike is changed from
the setting it was delivered with. Impaired perform-
ance will significantly increase the risk of injury to the
rider and/or damage to the eBike.
Read and observe all the safety warnings and direc-
u
tions contained in these operating instructions and in
the operating instructions of your eBike and the brake
manufacturer.
The safety information in these operating instructions is di-
vided into the following categories:
– WARNING – Danger with a moderate degree of risk.
Failure to observe this instruction may result in death or
serious injury.
– CAUTION – Danger with a low degree of risk.
Failure to observe this instruction may result in minor to
moderate injury.
– NOTE – Specific information to improve handling.
This is used in reference to operating instructions,
checks, adjustments and maintenance work.
Safety Instructions for the ABS
Tampering with the system components is not permit-
u
ted under any circumstances. The rider must adapt
their riding style to the environmental conditions (e.g.
available coefficient of friction between the tyres and
the ground, steep inclines, weather, additional loads,
etc.). Carrying an additional load that changes the
vehicle's centre of gravity in any way (e.g. a basket or
a child seat on the handlebars), which could increase
the tendency to tip over, is not recommended.
WARNING – tampering with components of the ABS
u
will prevent it from working correctly.
If any components of the braking system or the ABS are
tampered with, modified, or replaced with unauthorised
components, this may prevent the ABS from working as it
should. Correct operation cannot be guaranteed and
there is a greater risk of falling. Servicing and repairs
must always be carried out by authorised specialists. De-
fective parts must always be replaced with original parts.
WARNING – only use the brake fluid specified by the
u
relevant brake manufacturer
Only the brake fluid intended for the respective founda-
Bosch eBike Systems
tion brake and specified by the relevant brake manufac-
turer may ever be used as brake fluid. If another brake
fluid is used, correct operation cannot be guaranteed and
there is a greater risk of falling. Servicing and repairs
must always be carried out by authorised specialists.
WARNING – ABS increases braking distance.
u
The ABS prevents the front wheel from locking. This signi-
ficantly improves rider safety by reducing the risk of skid-
ding on low-friction surfaces and pitching over on high-
friction surfaces. In some situations, however, system in-
tervention may increase your braking distance. Always
adapt your riding style to the present environmental con-
ditions and your personal cycling abilities.
WARNING – reckless riding
u
The presence of the ABS does not absolve the rider of the
need to exercise due caution. The system is primarily de-
signed to provide an additional safeguard in emergency
situations. The rider is always responsible for adapting
their riding style to the situation on the road.
WARNING – braking around corners
u
The ABS is a safety system that reduces the risk of the
wheels locking. There is an inherently greater risk of fall-
ing when braking around corners. The rider is always re-
sponsible for adapting their riding style to the situation on
the road.
WARNING – ABS intervention is limited.
u
In extreme riding situations, the ABS may not be able to
control the eBike all the way through to a complete stop.
The ABS function can be re-enabled for braking by briefly
releasing the front-wheel brake. Always adapt your riding
style to the present environmental conditions and your
personal cycling abilities.
WARNING – eBike pitchover
u
The ABS is not always able to prevent the eBike pitching
over in extreme riding situations (e.g. when carrying a
heavy bag with a high centre of gravity or the eBike having
a high centre of gravity, e.g. due to the saddle being set
high as a result of a small frame, or variations in the road
surface or steep descents). Always adapt your riding style
to the present environmental conditions and your per-
sonal cycling abilities.
WARNING – air in the hydraulic system
u
If air gets into the brake system, the function and use-
fulness of the ABS is significantly impaired. The air in
the system means that less braking force can be built
up, especially following intervention by the ABS, in
which the brake lever also moves a little closer to the
handlebars. There is an additional risk of crushing to
fingers that are not wrapped around the brake lever
and remain on the handle while braking. Before every
journey, you should therefore apply the brake to check
whether there is a clearly noticeable pressure point and
whether there is sufficient clearance between the brake
lever and the handlebar grip. The pressure point should
be at approximately 1/3 of the brake lever travel. In case
of doubt, set the brake lever to the maximum possible
length of travel. If air finds its way into the brake system,
please have it bled by a professional. Always adapt your
