Switching the push assistance on/off
The walk assistance makes it easier to push your eBike. The
speed in this function depends on the selected gear and can
reach a maximum of 6 km/h.
The push assistance function must only be used when
u
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.
To activate the walk assistance, briefly press the WALK but-
ton on your on-board computer. Once it is activated, press
the + button within 10 s and keep it held down. The eBike
drive is now switched on.
Note: The push assistance cannot be activated at assistance
level OFF.
The walk assistance is switched off as soon as one of the fol-
lowing occurs:
– You release the + button (15),
– the wheels of the eBike are locked (e.g. by applying the
brakes or hitting an obstacle),
– the speed exceeds 6 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, 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 Your eBike
When does the drive work?
The drive assists your cycling only when you are pedalling. If
you do not pedal, the assistance will not work. The drive
power always depends on the pedalling force you apply.
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 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 walk assistance function, in
which the eBike can be pushed at low speed without ped-

alling. The pedals may rotate when the walk 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 or by
setting the assistance level to OFF. The same applies when
the eBike battery is drained.
Interaction between the Drive Unit and Gear-shifting
The gear shifting should be used with an eBike in the same
way as with a normal bicycle (observe the operating instruc-
tions of your eBike on this point).
Irrespective of the type of gear shifting, it is advisable that
you briefly reduce the pressure on the pedals when changing
gear. This will aid gear shifting 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 eBike battery
– Route profile (gradients) and conditions (road surface)
– Headwind and ambient temperature
– Weight of eBike, rider and luggage
For this reason, it is not possible to predict the range accur-
ately before and during a trip. However, as a general rule:
– With the same assistance level on the drive: The less en-
ergy you need to exert in order to reach a certain speed
(e.g. by changing gears optimally), the less energy the
drive will consume and the higher the range per battery
charge will be.
– The higher the selected assistance level under otherwise
constant conditions, the smaller the range will be.
