Setting the Assistance Level
On the on-board computer you can set how much the eBike
drive assists you while pedalling. The assistance level can be
changed at any time, even while cycling.
Note: For individual versions, it is possible that the assistance
level is pre-set and cannot be changed. It is also possible that
less assistance levels are available for selection than listed
here.
The following assistance levels (max.) are available:
– "OFF": The motor assistance is switched off, and the eBike
can be moved as a normal bicycle only by pedalling. The
push assistance cannot be activated in this assistance
level.
– "ECO": Effective assistance at maximum efficiency for
maximum cruising range
– "TOUR": Uniform assistance, for touring with long cruising
range
– "SPORT": Powerful assistance for sportive riding off road
as well as for urban traffic
– "TURBO": Maximum assistance, supporting highest
cadence for sportive riding
The motor output requested appears on the display of the on-
board computer (not on Purion). The maximum motor output
depends on the selected assistance level.

Switching the Push-assistance mode On/Off
The push-assistance feature makes it easier to push the
eBike. The speed in this function depends on the set gear and
cannot exceed 6 km/h (max.). The lower the set gear, the low-
er the speed in the push-assistance function (at full output).
 The push-assistance function may only be used when
pushing the eBike. Danger of injury when the wheels of
the eBike do not have ground contact while using the push-
assistance function.
To activate the push-assistance function, briefly press
button "WALK" on your on-board computer. After activation,
press button "+" within 3 s and keep it pressed. The eBike
drive is switched on.
Note: The push assistance cannot be activated in the "OFF"
assistance level.
The push assistance is switched off as soon as one of the
following occurs:
– You release the "+" button;
– The wheels of the eBike are prevented from turning (e.g.
by braking or being hit by your leg);
– The speed exceeds 6 km/h.

the push-assistance function may vary by region.
Switching bike lights on/off
In the version which has the bike lights powered by the eBike
system, the front and rear lights can be switched on and off at
the same time via the on-board computer.
Notes on Riding with the eBike System
When does the eBike Drive Unit Operate?
The eBike drive unit assists you when riding, as long as you
step into the pedals. Without pedaling, there is no assistance.
The motor output always depends on the amount of your
pedaling power.
When applying less pedaling power, the assistance or support
will be lower than when applying a lot of pedaling power. This
applies independent of the assistance Level.
The eBike drive automatically switches off at speeds in excess
of 25 km/h. When the speed falls below 25 km/h, the drive is
automatically available again.
An exception applies to the push-assistance function, in
which the eBike can be pushed at low speed without pedal-
ling. The pedals may also rotate when the push assistance is
used.
The eBike can also be ridden as a normal bicycle without
assistance at any time, by either switching off the eBike
system or setting the assistance level to "OFF". The same
applies when the battery pack is empty.
Interaction of the eBike System with the Bicycle Gears
The bicycle gears should be used as with a normal bicycle,
even with eBike motor assistance (please observe the operat-
ing instructions of your eBike).
Independent of the type of gearing, it is recommended to
briefly interrupt the pedaling while changing gears. This
makes changing gears easier and reduces the wear of the
drive train.
By selecting the right gear, you can increase the speed and
range with the same pedaling effort.
Gathering First Experience
It is recommended to gather first experience with the eBike
away from roads with heavy traffic.
Test the various assistance levels. Start with the lowest assis-
tance level. As soon as you feel confident, you can ride your
eBike in traffic like any other bike.
Test the operating range of your eBike under different condi-
tions before planning longer and more challenging rides.
