Operation
Initial Operation
Requirements
The eBike system can only be activated when the following re-
quirements are met:
– A sufficiently charged eBike battery pack is inserted (see
operating instructions of the battery pack).
– The on-board computer is properly inserted in the holder
(see “Inserting and removing the on-board computer”,
page English–2).
Switching the eBike System On/Off
Options for switching on the eBike system:
– Place the on-board computer into the holder 4.
– When the on-board computer and the eBike battery pack
are inserted, briefly press the On/Off button 5 of the on-
board computer.
– With the on-board computer inserted, push the On/Off
button on the eBike battery (bicycle manufacturer solu-
tions are possible whereby there is no access to the bat-
tery On/Off button; see the battery operating instruc-
tions).
The drive is activated as soon as you step on the pedals (ex-
cept for in the push assistance function or in assistance level
“OFF”). The motor output depends on the settings of the as-
sistance level on the on-board computer.
As soon as you stop pedaling when in normal operation, or as
soon as you have reached a speed of 25/45 km/h, the assis-
tance from the eBike drive is switched off. The drive is auto-
matically re-activated as soon you start pedaling again and the
speed is below 25/45 km/h.
