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 bat-
tery 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 the eBike battery pack off by using its On/Off
button (see battery pack operating instructions.)
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.

Indications and Settings of the on-board
computer
Symbols and their meaning
Energy supply of the on-board computer
The on-board computer is supplied with voltage by two
CR2016 button cells.
Changing the Batteries
If the on-board computer shows “LOW BAT” on the display, remove the on-board computer from the handlebars
by unscrewing the fastening screw 3 of the on-board computer. Open the battery lid 10 using a suitable coin, remove
the used batteries and insert new CR 2016 batteries. You
can obtain the batteries recommended by Bosch from your
eBike dealer.
Pay attention to the correct polarity when inserting the batteries.
Close the battery compartment again and fasten the onboard computer to your eBike’s handlebars using the fastening screw 3.
Battery charge-control indicator
The battery charge-control indicator g displays the charge
level of the eBike battery pack. The charge level of the eBike
battery pack can also be checked on the LEDs of the battery
pack itself.
Switching the Walk Assistance On/Off
The walk assistance can make it easier for you to push the
eBike. The speed of this function depends on the selected
gear and can reach a maximum of 3.7 mph. The lower the
selected gear, the lower the speed of the walk assistance
function (at full capacity).
Using the walk assistance function is only recom-
mended when pushing the eBike. There is risk of injury
if the wheels of the eBike are not in contact with the
ground while using the walk assistance.
To activate the walk assistance function, short-press the
button “WALK” on your on-board computer. After activation, press button “+” within 3 s and keep it pressed. The
eBike drive is switched on.
Note: The walk assistance cannot be activated in the “OFF”
assistance level.
The walk assistance is switched off as soon as one of the
following occurs:
– you release the button “+” 6,
– the wheels of the eBike are stopped (e.g. by actuating
the brakes or impacting against an obstacle),
– the speed exceeds 3.7 mph.
Note: On some systems the walk assistance function can
be started directly by pressing the “WALK” button.

On indicator g, each bar of the battery pack symbol is
equivalent to a capacity of approx. 20 %:
The eBike battery is fully charged.
The eBike battery should be recharged.
The LEDs of the charge-control indicator on the
battery extinguish. The capacity for assisting the
drive has been used up, and assistance is gently
switched off. The remaining capacity is made available for the lighting. The indicator flashes.
The capacity of the eBike battery pack is enough for
about 2 hours of lighting.

Setting the Assistance Level
On the on-board computer you can set how much the eBike
drive assists you while pedaling. The assistance level can
be changed at any time, even while cycling.
Note: For individual versions, it is possible that the assistance level is preset and cannot be changed. It is also possible that fewer assistance levels are available for selection
than listed here.
Once it is switched on, the eBike system is in the “OFF”
mode.
The following assistance levels (max.) are available:
– “OFF”: The motor assistance is switched off, the eBike
can be operated as a normal bicycle through pedaling.
– “ECO”: Effective assistance at maximum efficiency for
maximum cruising range
– “TOUR”: Uniform assistance, for touring with long cruis-
ing range
– “SPORT”: Powerful assistance for sporty off-road rid-
ing, as well as for urban traffic
– “TURBO”: Maximum assistance, supporting the highest
speed for sporty riding
To increase the assistance level, short-press the button
“+” 6 on the on-board computer repeatedly until the re-
quired assistance level appears in indicator i. To decrease
the assistance level, short-press the button “–” 5.
Switching bike lights On/Off
In the version which has the bike lights powered by the
eBike system, medium-press the button “+” to switch
on the front and rear lights at the same time. To switch off
the bike lights, long-press the button “+”.
The lighting symbol h is displayed when the light is on.
Switching the driving light on and off has no effect on the
backlighting for the display. The backlighting for the display
is active as soon as the system or the display is switched on.
Speed and Distance Indicator
The speed indicator a always displays the current speed.
Indicator i always displays the last setting as standard. Re-
peatedly medium-press the button “–” to display the trip
distance “TRIP”, the total distance “TOTAL” and the range of
the battery pack “RANGE” one after the other. (Shortpressing the button “–” will decrease the assistance level!)
The trip distance “TRIP” is reset by simultaneously longpressing the buttons “+” and “–”. The display will initially show “RESET”. If you continue to press both buttons, the
trip distance “TRIP” will be set to “0”.
You can switch the displayed values from kilometers to
miles by holding down button “–” and briefly pressing
the On/Off button 1 .
The versions of the subsystems can be displayed for the
purposes of servicing. With the system switched off, simultaneously press buttons “–” and “+” and then press the
On/Off button 1 .
The USB socket is reserved for connecting diagnostic systems. The USB socket does not have any other function.
The USB connection must always be completely
sealed with the protective cap 8.
