Note: For a description of the brakes and how they function,
please refer to the instructions provided by the brake manu-
facturer.
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.
0 275 008 BAS | (19.12.2018)
– 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
are working correctly before setting off.
Check to ensure that the thickness of the brake pads and the
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.

The anti-lock braking system indicator lamp
The anti-lock braking system indicator lamp must come on
after starting the system and must go out again once you
start riding at a speed of approximately 5 km/h. If the ABS
indicator lamp does not come on after starting your eBike
system, this means that the ABS is defective. A fault code to
this effect will also be shown on the display to notify the
rider.
Please make sure you have all repairs carried out by a
u
professional.
If the indicator lamp 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. 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.
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 anti-lock braking system indicator lamp may come
on in extreme riding situations where the front wheel and the
rear wheel are turning 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 (assembly stands). This will switch the anti-lock
braking system off. To re-enable the anti-lock braking sys-
tem, you will need to 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 lamp is present
and lit; otherwise the indicator lamp is defective.
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, light and ABS) will nevertheless
remain enabled until the battery's reserve has been used up
too. The eBike system – and therefore the ABS – will not
switch off until the battery is almost completely drained.
The indicator lamp will come on again for approximately five
seconds before the system switches off completely.
From this point onwards, the ABS indicator lamp will remain
off despite ABS control being unavailable. If the eBike is not
fitted with a battery or its battery is drained, ABS is disabled.
The brake system will continue working, simply without the
control provided by the anti-lock braking system.
You will need to charge the battery before you can re-enable
your eBike system and the ABS function.
WARNING – ABS will be disabled without a power sup-
u
ply!
If the power fails, the battery is drained or the battery is
not fitted, the ABS will be disabled and the ABS indicator
lamp will not come on.

Maintenance and servicing
Maintenance and cleaning
Servicing and repairs must only be carried out by pro-
u
fessionals. Defective parts must always be replaced
with original parts.
Have your eBike system checked by an expert at least once a
year (including mechanical parts, up-to-dateness of system
software).
Please have your eBike serviced and repaired by an author-
ised bicycle dealer.
After-sales service and advice on using products
If you have any questions about the eBike system and its
components, contact an authorised bicycle dealer.

hold waste.
In accordance with Directive 2012/19/EU
and Directive 2006/66/EC respectively, elec-
tronic devices that are no longer usable and de-
