Bosch eBike ABS BAS3311 Notice D'utilisation D'origine page 11

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 turning and limits this by decreasing
the braking pressure and thereby stabilizing the
eBike.
Once the eBike has been stabilized, 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 re-
peated in order to keep the front wheel at the grip
limit at all times and therefore optimize exploitation
of the coefficient of friction between the tires and the
ground.
The anti-lock braking system is fully assembled by the
manufacturer and must not be modified.
Warning: If you would like to attach other acces-
sories to the handlebars, bear in mind that the han-
dlebars must be able to turn freely at least 60° to ei-
ther side from the center position. Steering limiters
may need to be fitted.

How it works
A certain degree of pulsing or vibrating in the brake
lever is considered normal and can be expected dur-
ing operation of the ABS system.
The ABS function is ended when one of the following
happens:
– The hydraulic accumulator in the ABS control unit is
full.
– The eBike comes to a stop.
– The rider releases the brake.
Due to the way the system operates, the ABS can only
step in from a minimum speed of 3 mph.
In addition to the ABS function, a system has been in-
tegrated 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 maneuvers.
