How it works

When the brakes are operated, the ABS function identifies
critical slippage using the wheel speed sensors on the front
and rear wheels and limits slippage on the front wheel by re-
ducing 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 locks
again, the pressure is reduced as before. This process is re-
peated in order to keep the wheel at the grip limit at all times
and therefore optimise exploitation of the coefficient of fric-
tion 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. 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 system on. You can find
more information about this in the section entitled (see "The
anti-lock braking system indicator lamp",
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
BAS100
are working correctly before setting off.
°C −5 ... +40
Check to ensure that the thickness of the brake pads and the
°C +10 ... +40
brake discs meet the manufacturer's specifications before
setting off.

Before the first journey
Familiarise yourself with how the brakes 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
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 anti-lock braking system may in-
crease your braking distance.
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.
