The assistance factor may vary in some models.

Maximum value

Switching the push assistance on/off

The push assistance aids you when pushing your eBike. The
speed in this function depends on the selected gear and can
reach a maximum of

km/h

. The lower the selected gear,

the lower the speed of the push assistance function (at full
power).

The push assistance function must only be used when
pushing the eBike.

There is a risk of injury if the wheels

of the eBike are not in contact with the ground while using
the push assistance.

activate

the push assistance, briefly press the

WALK

button on your on-board computer. After activation, press
the

button within 3 s and keep it pressed. The eBike drive

is switched on.

Note:

The push assistance cannot be activated at assistance

level

OFF

The push assistance is

switched off

as soon as one of the

following occurs:
– You release the

button;

– The wheels of the eBike are locked (e.g. by applying the

brakes or hitting an obstacle);

– The speed exceeds

km/h

The push assistance function is subject to local regulations;
the way it works may therefore differ from the description
above, or the function may even be deactivated completely.

Switching bicycle lights on/off

On the model where the bike lights are powered by the eBike
system, the front light and taillight can be switched on and
off at the same time via the on-board computer.
Check that your bike lights are working correctly before
every use.

Notes on cycling with the eBike
system

When does the eBike drive work?

The eBike drive assists your cycling only when you are ped-
alling. If you do not pedal, the assistance will not work. The
motor output always depends on the pedalling force you ap-
ply.

If you apply less force, you will receive less assistance than if
you apply a lot of force. This applies irrespective of the as-
sistance level.
The eBike drive automatically switches off at speeds over

25/45

km/h

. When the speed falls below

25/45

km/h

, the

drive automatically becomes available again.
An exception applies to the push assistance function, in
which the eBike can be pushed at low speed without ped-
alling. The pedals may rotate when the push assistance is in
use.
You can also use the eBike as a normal bicycle without as-
sistance at any time, either by switching off the eBike system
or by setting the assistance level to

OFF

. The same applies

when the battery is drained.

Interaction between the eBike system and gear-
shifting

The gear-shifting should be used with an eBike drive in the
same way as with a normal bicycle (observe the operating in-
structions of your eBike on this point).
Irrespective of the type of gear-shifting, it is advisable to
briefly stop pedalling when changing gear. This will facilitate
the gear change and reduce wear on the powertrain.
By selecting the correct gear, you can increase your speed
and range while applying the same amount of force.

Gaining initial experience

We recommend that you gain initial experience with the
eBike away from busy roads.
Test the various assistance levels, beginning with the lowest
level. As soon as you feel confident, you can ride your eBike
in traffic like any other bicycle.
Test the range of your eBike in different conditions before
planning longer and more demanding trips.

Influences on range

The range is affected by a number of factors, such as:
– Assistance level
– Speed
– Gear shifting behaviour
– Tyre type and tyre pressure
– Age and condition of the battery
– Route profile (gradients) and conditions (road surface)
– Headwind and ambient temperature
– Weight of eBike, rider and luggage
