The following assistance levels are available as a max-
imum:

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
– SPORT/eMTB:
SPORT: Powerful assistance, for mountain biking
and for cycling in urban traffic
eMTB: Optimum assistance whatever the terrain,
rapid acceleration when starting from a standstill,
improved dynamics, top performance (eMTB is
only available in combination with drive units
BDU250P CX, BDU365, BDU450 CX and
BDU480 CX. This also requires a software update.)
– TURBO: Maximum assistance even at high pedaling
speeds, for biking sports
To increase the assistance level, press the + but-
ton (15) on the operating unit repeatedly until the re-
quired assistance level appears on the indicator. To
decrease the assistance level, press the – but-
ton (12).
The requested motor output is shown on the display j.
The maximum motor output depends on the selected
assistance level.
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.
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.
To activate the push assistance, briefly press the
WALK button on your on-board computer. After acti-
Bosch eBike Systems
vation, press the + button within 3 s and keep it
pressed. The eBike drive is switched on.
Note: The push assistance cannot be activated at as-
sistance level OFF.
The push assistance is switched off as soon as one of
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.
Switching bicycle lights on/off
On the model in which the lighting is powered by the
eBike system, the front and rear lights can be
switched on and off at the same time via the on-board
computer using the bike light button (1).
Before starting each journey, check that your bike
lights are working correctly.
If the lighting is switched on, the bike light indicator f
lights up in the status bar of the display.
Switching the bike lights on and off has no effect on
the backlighting of the display.
Lock (premium function)
The lock function is available to purchase from
the <Shop> in the eBike Connect app. Once the lock
function is switched on, the assistance from the eBike
drive unit is deactivated by removing the on-board
computer. Activation is then only possible via the on-
board computer that is associated with the eBike.
More detailed instructions regarding this can be
found in the online operating instructions at
www.Bosch-eBike.com.
