CAUTION – damage to components or risk of crushing
u
Take care not to trap components such as brake lines,
cable harnesses or parts of the body between the ABS
control unit and the frame. This will help prevent damage
to components and bodily injury, even in the event of the
handlebars fully locking.
Privacy notice
When you connect the eBike to the Bosch DiagnosticTool,
data is transferred to Bosch eBike Systems (Robert Bosch
GmbH) for the purposes of product improvement regarding
the ABS (e.g. braking force delay, etc.) You can find more in-
formation about this on the Bosch eBike website at

How it works
When the front-wheel brake is operated, the ABS function
uses the wheel speed sensors on the front and rear wheels
to identify the tendency of the wheel to block and stop turn-
ing and limits this by decreasing the braking pressure and
thereby stabilising the eBike.
Once the eBike has been stabilised, precise increases in
braking pressure bring the front wheel back up to the locking
limit. This causes the lever to move a small distance towards
the handlebars with every braking impulse. If the front wheel
is tending to lock again, the pressure is reduced as before.
This process is repeated in order to keep the front wheel at
the grip limit at all times and therefore optimise exploitation
of the coefficient of friction between the tyres and the
ground.
A certain degree of pulsing or vibrating in the brake lever is
considered normal and can be expected during operation of
the ABS system.
The ABS function is ended when one of the following hap-
pens:
– The hydraulic accumulator in the ABS control unit is full.
– The eBike comes to a stop.
– The rider releases the brake.
In addition to the ABS function, a system has been integ-
rated that detects when the rear wheel lifts off the ground
during heavy braking. This means that, within certain limits,
forward pitchover can be counteracted during very hard
braking manoeuvres.
Fitting
The anti-lock braking system is fully assembled by the manu-
facturer and must not be modified.
Warning! If you would like to attach other accessories to the
handlebars, bear in mind that the handlebars must be able
to turn freely at least 60° to either side from the centre posi-
tion. Crushing of fingers can be prevented by leaving a clear-
ance of 25 mm. Steering limiters may need to be fitted.
Operation
Before every journey
Check to ensure that the ABS indicator lamp is working cor-
rectly whenever you switch the eBike on. You can find more
information about this in the section entitled (see "ABS in-
dicator light", page English – 3).
Please check the condition and roadworthiness of the eBike
before every journey. It is the eBike rider's responsibility to
check the eBike is in perfect working order and fully road-
worthy before every journey. Using the eBike with known
faults increases the risk of injury to the rider.
Always check to ensure that the front- and rear-wheel brakes
are working correctly before setting off.
Check to ensure that the thickness of the brake pads and the
brake discs meets the manufacturer's specifications before
setting off.
