Technical Data
Operation
Requirements
The eBike system can only be activated when the following
requirements are met:
– A sufficiently charged battery pack is inserted (see
battery pack operating instructions).
– The speed sensor is connected properly (see drive unit
operating instructions).
Initial Operation
Switching the eBike System On/Off
Options for
switching on
the eBike system:
– Press the On/Off button
1
of the on-board computer
with the eBike battery pack inserted.
– Press the On/Off button of the eBike battery pack (see
battery pack operating instructions).
Once it is switched on, the eBike system is in the
“OFF”
mode. Select the desired assistance level and take off.
The drive is activated as soon as you put pressure on the
pedals. The assistance level depends upon the on-board
computer settings.
As soon as you stop pedaling when in normal operation, or
as soon as you have reached a speed of 20/28 mph, the
assistance from the eBike drive unit is switched off. The
motor assistance is automatically re-activated as soon you
start pedaling again and the speed is below 20/28 mph.
Options for
switching off
the eBike system:
– Press the On/Off button
1
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).
The system shuts down after being switched off; this takes
approximately 3 seconds. It cannot be switched back on
immediately until shutdown has been completed.
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.
Note:
Always switch off the eBike system when you park
the eBike.
Note:
If the batteries of the on-board computer are empty,
you can still switch on your eBike using the bike’s battery
pack. It is, however, recommended that you replace the
internal batteries as soon as possible in order to avoid
damage.
