Bosch KALKHOFF PERFORMANCE, Original User Manual

Page: 58 / 103

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.
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 (bi-
cycle manufacturer-specific solutions are possible where-
by 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 inter-
nal batteries as soon as possible in order to avoid damage.

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).

within 3 s and keep it pressed. The eBike
drive is switched on.
