Bosch eBike ABS BAS3311 Notice D'utilisation D'origine page 9

the front and rear wheels and limits slippage by reducing the
braking pressure and thereby stabilising the wheel.
Once the wheel has been stabilised, precise increases in
pressure bring the 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 wheel is tend-
ing to lock again, the pressure is reduced as before. This pro-
cess is repeated in order to keep the wheel at the grip limit at
all times and therefore optimise exploitation of the coeffi-
cient of friction between the tyres and the ground.
The ABS function is ended when one of the following hap-
pens:
– The memory of 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. Steering limiters may need to be fitted.
Operation
It is not permitted to attach additional holders to the
u
fork, e.g. for panniers, in conjunction with an ABS.
Before every journey
Check to ensure that the ABS indicator light is working cor-
rectly on the display and/or operating unit whenever you
switch the eBike system on. You can find more information
about this in the section entitled (see "ABS indicator light",
page English – 3).
Please check the condition and roadworthiness of the eBike
before every journey. The eBike must be in perfect working
order during use.
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.
Before the first journey
Familiarise yourself with how the brakes and ABS work and
how they respond when you actuate them, for example by
practising your braking technique away from busy roads.
Disc brakes need a while to take effect and their braking
power increases over time. You should therefore bear in
mind that the braking force may increase while braking. This
also happens after replacing the brake pads or the disc. For
Bosch eBike Systems
information on changing the brake discs and brake pads, as
well as what to do when applying the brakes, please refer to
the instructions provided by the brake manufacturer.
During the journey
Adapt your riding style to the present riding situation, the
road conditions and your cycling abilities.
Please be aware that the ABS may increase your braking dis-
tance.
On slippery surfaces, the tyres skid more easily and there is
a greater risk of falling over. You should therefore reduce
your speed, applying the brakes in good time using a steady
pressure.
ABS indicator light
The ABS indicator light must come on after starting the sys-
tem and must go out again once you start riding at a speed of
approximately 5 km/h.
If the indicator light does not go out once you have started
riding or comes on while riding, this means that there is a
fault with the anti-lock braking system or there is a shutdown
of the ABS functionality indicated by the user. If a display is
connected, you will also be shown an error code on the dis-
play. You can also view a saved error code on the eBike
Flow app. This means the anti-lock braking system is no
longer active. The brake system will continue working,
simply without the control provided by the anti-lock braking
system.
Please make sure you have all repairs carried out by a
u
professional.
The functionality of the rear-wheel brake is not affected by
whether or not the anti-lock braking system is working.
WARNING – ABS indicator lamp lit.
u
If the ABS indicator lamp is lit, this means that the ABS
function is disabled.
Note: The ABS indicator light may come on in extreme riding
situations where the front wheel and the rear wheel are turn-
ing at very different speeds, for example when riding solely
on the rear wheel or if the wheel is turning for an unusually
long period without making contact with the ground (as-
sembly stands). This will switch the anti-lock braking system
off. To re-enable the anti-lock braking system, stop the eBike
and restart it (switch it off and on again).
CAUTION – Faults with the ABS cannot be signalled if
u
the ABS indicator lamp is defective.
When starting the eBike system, the rider must therefore
check to ensure that the ABS indicator light is lit; other-
wise the eBike system will indicate a critical error by
flashing red on the operating unit. Contact a dealer if this
happens.
Riding with the eBike battery drained
If the battery's state of charge falls below a defined
threshold, the system will disable motor assistance first. The
system (including display and/or operating unit, light and
ABS) will nevertheless remain enabled until the battery's re-
serve has been used up too. The eBike system – and there-
