Operation

Initial Operation

Requirements
The drive of your eBike can only be activated
when the following requirements are met:
– A sufficiently charged battery is inserted (see
operating instructions of the battery).
– The drive HMI is properly inserted in the
holder (see "Inserting and Removing the
Drive HMI", page 26).
– The drive HMI is properly connected (see
"Checking the Speed Sensor", page 26).
Switching the Drive On/Off
Insert the battery into the holder and switch it
on via the On/Off button (see operating instruc-
tions of the battery).
Note: When switching on the battery, the pedals
of the eBike may not be subject to load, as oth-
erwise the output capacity of the drive will be
limited.
If the battery was inadvertently switched on
with load applied to the pedals, then switch it
off and then on again without load.
Switching on the battery also switches on the
display of the drive HMI. The drive HMI indicates
the charge condition of the battery as well as
the settings of the drive unit.
The drive is activated as soon as you step into
the pedals. The assistance level depends on the
settings of the drive HMI.
As soon as you stop pedaling, or as soon as you
have reached a speed of 25 km/h, the assist-
ance 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.
To switch off the drive, switch the battery off via
the On/Off button (see operating instructions of
the battery).
When no power output of the drive is requested
for approx. 10 minutes, (e.g., because the eBike
is parked), the battery automatically switches
off to save energy.

Indications and Settings of the
Drive HMI
Note: Indications and settings on the drive HMI
are only possible when the eBike battery is
switched on. The drive HMI does not have an
own power supply.

Charge Condition of the Battery

Besides on the charge-control indicator on the
battery itself, the charge condition can also be
read from indicator f of the drive HMI.
On indicator f, each bar of the battery symbol is
equivalent to a capacity of approx. 20 %:
100 % to 80 % capacity
20 % to 5 % capacity; the battery
should be recharged.
Less than 5 % capacity; drive assist-
ance is no longer possible. The LEDs
of the charge-control indicator on the battery
go out.
When the eBike lighting is powered via the bat-
tery (country-specific), the capacity upon first
indication of the empty battery symbol will be
sufficient for approx. 2 hours of lighting. When
the symbol begins to flash, the lighting will con-
tinue to operate only for a short period.
Adjusting the Assistance Mode
The level of assistance of the eBike drive when
pedaling can be adjusted via the drive HMI.
Note: For individual versions, it is possible that
the the assistance mode is pre-set and cannot
be changed. It is also possible that less modes
are available for selection than listed here.
A maximum of four assistance modes are avail-
able:
"ECO": Effective assistance at max-
imum efficiency for maximum cruis-
ing range
"TOUR": Uniform assistance, for
touring with long cruising range
