Setting the Assistance Level
The level of assistance of the eBike drive unit when pedal-
ing can be adjusted via the operating unit 10. The assis-
tance level can be changed anytime, even during riding.
Note: For individual versions, it is possible that the assis-
tance level is preset and cannot be changed. It is also pos-
sible that fewer assistance levels are available for selection
than listed here.
The following assistance levels (max.) are available:
– "OFF": The motor assistance is switched off, the eBike
can be operated as a normal bicycle through pedaling.
– "ECO": Effective assistance at maximum efficiency for
maximum cruising range
– "TOUR": Uniform assistance, for touring with long cruis-
ing range
– "SPORT": Powerful assistance for sporty off-road rid-
ing, as well as for urban traffic
– "TURBO": Maximum assistance, supporting the highest
speed for sporty riding
To increase the assistance level, press the "+" button 13
on the operating unit until the desired assistance level is
displayed in indicator b; to decrease the assistance level,
press the "–" button 12.

The requested motor output is displayed in indicator a. The
maximum motor output depends on the selected assis-
tance level.
When the on-board computer is removed from the holder
4, then the last indicated level is not stored and the on-
board computer is reset to the "OFF" mode.
Once it is switched on, the eBike system is in the "OFF"
mode.

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 follow the operat-
ing instructions for 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 on the
drive train.
By selecting the right gear, you can increase the speed and
range with the same pedaling effort.
For this reason, follow the shift recommendations provided
by indications g and h on your display. If indication g is dis-
played, you should shift to a higher gear with lower ca-
dence. If indication h is displayed, you should select a lower
gear with higher cadence.
Switching bike lights On/Off
If your lights are set up to be powered by the eBike system,
then you can use the 2 button on the on-board computer to
simultaneously switch both the front light and the rear light
on and off.
When the lighting is switched on, "Lights on" appears, and
when the lighting is switched off, "Lights off" appears for
approx. 1 s in the text indicator d. The light symbol c is dis-
played when the light is on.
Switching the driving light on and off has no effect on the
backlighting for the display. The backlighting for the display
is active as soon as the system or the display is switched on.
