Start-up
Requirements
The eBike system can only be activated when the fol-
lowing requirements are met:
– A sufficiently charged battery is inserted (see bat-
tery operating instructions).
– The speed sensor is connected properly (see drive
unit operating instructions).
Switching the eBike system on/off
The following options are available for switching on
the eBike system:
– Press the on/off button (1) of the on-board com-
puter with the eBike battery inserted.
– Press the on/off button of the eBike battery (see
battery operating instructions).
The drive is activated as soon as you start pedaling
(except for in the push assistance function or with the
assistance level OFF). The motor output depends on
which assistance level is set on the on-board com-
puter.
As soon as you stop pedaling when in normal opera-
tion, or as soon as you have reached a speed of
20/28 mph, the eBike drive unit switches off the as-
sistance. The drive is automatically re-activated as
soon you start pedaling again and the speed is below
20/28 mph.
The following options are available for switching off
the eBike system:
Bosch eBike Systems
Operation
– Press the on/off button (1) of the on-board com-
puter.
– Switch off the eBike battery using its on/off button
(some bicycle manufacturer-specific solutions pre-
vent access to the battery on/off button; see the bi-
cycle manufacturer operating instructions).
The system shuts down after being switched off. This
takes approximately three seconds. It cannot be
switched back on until shutdown has been com-
pleted.
If the eBike is not moved for approx. ten minutes and
no button is pressed on the on-board computer, the
eBike system switches off 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
drained, you can still switch on your eBike using the
bike's battery. It is, however, recommended that you
replace the internal batteries as soon as possible in
order to avoid damage.
Energy supply of the on-board computer
The on-board computer is supplied with voltage by
two CR2016 button cells.

Changing the batteries
(10)
If the on-board computer shows LOW BAT on the dis-
play, remove the on-board computer from the handle-
bars by unscrewing the fastening screw (3) of the on-
board computer. Open the battery compartment
cover (10) using a suitable coin, remove the used
batteries and insert new CR2016 batteries. You can
obtain batteries recommended by Bosch from your
bicycle dealer.
When inserting the batteries, ensure that the polarity
is correct.
Close the battery compartment again and fasten the
on-board computer to your eBike's handlebars using
the fastening screw (3).
Switching the push assistance on/off
The push assistance aids you when pushing your
eBike. The speed of this function depends on the se-
lected gear and can reach a maximum of 3.7 mph.
1 270 U20 XBP | (08.04.2020)
The lower the selected gear, the lower the speed of
the push assistance function (at full power).
The push assistance function must only be used
u
when pushing the eBike. There is a risk of injury if
the wheels of the eBike are not in contact with the
ground while using the push assistance.

the following occurs:
– You release the + button;
– the wheels of the eBike are locked (e.g. by applying
the brakes or hitting an obstacle);
– the speed exceeds 3.7 mph.
The push assistance function is subject to local regu-
lations; the way it works may therefore differ from the
description above. It can also be deactivated.
Setting the assistance level
You can set the level at which the eBike drive assists
you while pedaling on the on-board computer. The as-
sistance level can be changed at any time, even while
cycling.
Note: In some models, the assistance level may be
preset and cannot be changed. There may also be
fewer assistance levels available than stated here.
The following assistance levels are available as a max-
imum:
– OFF: Motor assistance is switched off. The eBike
can just be moved by pedaling, as with a normal bi-
cycle. The push assistance cannot be activated at
this assistance level.
– ECO: Effective assistance with maximum effi-
ciency, for maximum range
– TOUR: Steady assistance, long range for touring
