As soon as you stop pedaling when in normal operation, or as
soon as you have reached a speed of 25 km/h, the assistance
from the eBike drive is switched off. The drive is automatically
re-activated as soon you start pedaling again and the speed is
below 25 km/h.
Options for switching off the eBike system:
– Press the On/Off button of the on-board computer.
– Switch off the eBike battery using its On/Off button
(bicycle manufacturer-specific solutions are possible
whereby there is no access to the battery On/Off button;
see the bicycle manufacturer operating instructions).
– Remove the on-board computer out of its holder.
If the eBike is not moved and no button is pressed on the on-
board computer for 10 minutes, the eBike system will shut
down automatically in order to save energy.
eShift (optional)
eShift is the integration of electronic gear shifting systems
into the eBike system. The eShift components are electrically
connected to the drive unit by the manufacturer. The separate
operating instructions describe how to operate the electronic
gear-shifting systems.
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.
When the eBike is configured in "eMTB Mode" by the manu-
facturer, the assistance factor and torque are dynamically
adjusted as a function of the force you exert on the pedals.
"eMTB Mode" is only available for Performance Line CX
drives.
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/start 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"/"eMTB"
"SPORT": Powerful assistance for sportive riding off road
as well as for urban traffic
"eMTB": Optimal assistance whatever the terrain, rapid
acceleration when starting from a standstill, improved
dynamics and top performance.
– "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.
Note: On some systems the push-assistance function can be
started directly by pressing the "WALK" button.
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.
