Safety Notes
Read all safety warnings and all instructions. Failure to follow the warnings and in-
structions may result in electric shock, fire
and/or serious injury.
Save all safety warnings and instructions for future reference.
The term “battery pack” used in these operating instructions, irrespective of model, refers both to standard battery packs (battery packs with holder on the bike frame) and to rack-type battery packs (battery packs with holder in the rear rack/carrier).
f Do not open the drive unit yourself. The drive unit must
be repaired only by qualified experts and only with
original spare parts. This will ensure that the safety of the
drive unit is maintained. Unauthorised opening of the drive
unit will void warranty claims.
f All components mounted to the drive unit and all other
components of the eBike drive (e. g., the chainwheel,
chainwheel seat, pedals) may be replaced only with
identical components or components specifically approved for your eBike by the bicycle manufacturer. This
protects the drive unit against overload and damage.
f Remove the battery pack from the eBike before begin-
ning work (e.g. inspection, repair, assembly, maintenance, work on the chain, etc.) on the eBike, transporting it by car or plane, or storing it. Unintentional
activation of the eBike system poses a risk of injury.
f The eBike system can switch itself on when the eBike is
pushed backwards.
f The push-assistance function may only be used when
pushing the eBike. Danger of injury when the wheels of
the eBike do not have ground contact while using the pushassistance function.
f If the push assistance is switched on, the pedals will
also rotate on bikes with back-pedalling function. When
the push assistance is activated, make sure that your legs
are a sufficient distance away from the rotating pedals.
There is a risk of injury.
f Use only original Bosch battery packs approved for your
eBike by the manufacturer. Using other battery packs can
lead to injuries and pose a fire hazard. When using other battery packs, Bosch shall not assume any liability and warranty.
f Do not make any modifications to your eBike system or
fit any other products which would be suitable for increasing the performance of your eBike system. This
normally reduces the lifetime of the system and risks damage to the drive unit and the bike. There is also a risk of losing the guarantee and warranty claims on the bike you have
purchased. By handling the system improperly you are also endangering your safety and that of other road users,
thus running the risk of high personal liability costs and
possibly even criminal prosecution in the event of accidents attributable to manipulation.
f Please observe all national regulations on registering
and using eBikes.
f Read and observe the safety warnings and instructions
in all operating instructions of the eBike system and in
the operating instructions of your eBike.

Assembly
Inserting and removing the battery pack
For inserting and removing the eBike battery pack in/from the
eBike, please read and observe the battery pack operating instructions.
Checking the Speed Sensor (see figure A)
The speed sensor 2 and its spoke magnet 3 must be mounted
in such a manner that the spoke magnet, after a turn of the
wheel, moves past the speed sensor with a clearance of at
least 5 mm, yet no more than 17 mm.
Note: If the distance between speed sensor 2 and spoke mag-
net 3 is too small or too large, or if the speed sensor 2 is not
properly connected, the speed indication will fail, and the
eBike drive unit will operate in emergency mode.
In this case, loosen the screw of the spoke magnet 3 and fasten the spoke magnet to the spoke in such a manner that it
runs past the mark of the speed sensor at the correct clearance. If the speed is still not being indicated in the speed indication after this, please contact an authorised bicycle dealer.
Operation
Initial 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 on-board computer is properly inserted in the holder
(see on-board computer operating instructions).
– The speed sensor is connected properly (see “Checking
the Speed Sensor”, page English –2).
Switching the eBike System On/Off
Options for switching on the eBike system:
– If the on-board computer is already switched on when you
insert it into the holder, then the eBike system will be
switched on automatically.
– With the on-board computer and the eBike battery pack in-
serted, briefly press the On/Off button of the on-board computer (see on-board computer operating instructions).
– When the on-board computer is inserted, press the On/Off
button of the eBike battery pack (see battery pack operating instructions).
The drive is activated as soon as you step on the pedals (except when in the push aid feature, see “Switching the Pushassistance mode On/Off”, page English –3). The motor output depends on the settings of the assistance level on the onboard computer.
As soon as you stop pedaling when in normal operation, or as
soon as you have reached a speed of 25 km/h, the assistance
from the eBike drive is switched off. The drive is automatically
re-activated as soon you start pedaling again and the speed is
below 25 km/h.
Options for switching off the eBike system:
– Press the On/Off button of the on-board computer.
– Switch the eBike battery pack off by its On/Off button (see
battery pack operating instructions).
– Remove the on-board computer out of its holder.
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.
eShift (optional)
eShift is the integration of automatic gear shifting systems into the eBike system. The eShift components are electrically
connected to the drive unit by the manufacturer. The operation of automatic gear shifting systems is described in the operating instructions of the on-board computer.
Setting the Assistance Level
On the on-board computer you can set how much the eBike
drive assists you while pedalling. The assistance level can be
changed at any time, even while cycling.
Note: For individual versions, it is possible that the assistance
level is pre-set and cannot be changed. It is also possible that
less assistance levels are available for selection than listed
here.
The following assistance levels (max.) are available:
– “OFF”: The motor assistance is switched off, and the eBike
can be moved as a normal bicycle only by pedalling. The
push assistance cannot be activated in this assistance level.
– “ECO”: Effective assistance at maximum efficiency for
maximum cruising range
– “TOUR”: Uniform assistance, for touring with long cruising
range
– “SPORT”: Powerful assistance for sportive riding off road
as well as for urban traffic
– “TURBO”: Maximum assistance, supporting highest ca-
dence for sportive riding
The requested motor output appears on the display of the onboard computer. The maximum motor output depends on the
selected assistance level.
Assistance Level Assistance Factor *

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 lower the speed in the push-assistance function (at full output).
f The push-assistance function may only be used when
pushing the eBike. Danger of injury when the wheels of
the eBike do not have ground contact while using the pushassistance function.
To activate the push-assistance function, briefly press 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 push assistance cannot be activated in the “OFF”
assistance level.
The push assistance is switched off as soon as one of the following occurs:
– you release button “+”,
– the wheels of the eBike are blocked (e.g. by actuating the
brakes or impacting against an obstacle),
– the speed exceeds 6 km/h.
Note: On some systems the push-assistance function can be
started directly by pressing the “WALK” button.
Back-pedalling function (optional)
For bikes with back-pedalling function, the pedals rotate
when the push aid is switched on. If the rotating pedals are
blocked, the push aid switches off.
Switching bike lights on/off
In the version which has the bike lights 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.
Notes on Riding with the eBike System
When does the eBike Drive Unit Operate?
The eBike drive unit assists you when riding, as long as you
step into the pedals. Without pedaling, there is no assistance.
The motor output always depends on the amount of your pedaling power.
When applying less pedaling power, the assistance or support
will be lower than when applying a lot of pedaling power. This
applies independent of the assistance Level.
The eBike drive automatically switches off at speeds in excess
of 25 km/h. When the speed falls below 25 km/h, the drive is
automatically available again.
An exception applies to the push-assistance function, in which
the eBike can be pushed at low speed without pedalling. The
pedals may also rotate when the push assistance is used.
The eBike can also be ridden as a normal bicycle without assistance at any time, by either switching off the eBike system
or setting the assistance level to “OFF”. The same applies
when the battery pack is empty.
Interaction of the eBike System with the Bicycle Gears
The bicycle gears should be used as with a normal bicycle,
even with eBike motor assistance (please observe the operating instructions of your eBike).
Independent of the type of gearing, it is recommended to
briefly interrupt the pedaling while changing gears. This
makes changing gears easier and reduces the wear of the
drive train.
By selecting the right gear, you can increase the speed and
range with the same pedaling effort.
Gathering First Experience
It is recommended to gather first experience with the eBike
away from roads with heavy traffic.
Test the various assistance levels. Start with the lowest assistance level. As soon as you feel confident, you can ride your
eBike in traffic like any other bike.
Test the operating range of your eBike under different conditions before planning longer and more challenging rides.
Influences on the Operating Range
The range is affected by a number of factors, such as:
– Assistance level
– Speed
– Gear changing behaviour
– Tyre type and tyre pressure
– Age and condition of the battery
– Route profile (gradients) and conditions (road surface)
– Headwind and ambient temperature
– Weight of eBike, driver and luggage.
For this reason, it is not possible to precisely predict the
range before and during a trip. General rules:
– With the same assistance level on the eBike drive: The less
energy you need to exert in order to reach a certain speed
(e.g. by changing gears optimally), the less energy the
eBike drive will consume and the higher the range per battery charge will be.
– The higher the assistance level under otherwise same con-
ditions, the lower the range.
Careful Handling of the eBike
Please observe the operating and storage temperatures of the
eBike components. Protect the drive unit, on-board computer
and battery against extreme temperatures (e.g. from intense
sunlight without adequate ventilation). The components (especially the battery pack) can become damaged through extreme temperatures.

temperature. Regularly recharge the on-board computer's
battery (at least every 3 months).
Battery Charge-control Indicator
The battery charge-control indicator i displays the charge level of the eBike battery pack, not that of the on-board computer’s internal battery pack. The charge level of the eBike battery pack can also be checked on the LEDs of the battery pack
itself.
If the on-board computer is removed from the holder 4, the
last displayed battery charge level is saved.
If an eBike is operated with two battery packs, the battery
charge-control indicator i displays the level of both battery
packs.
If an eBike has two battery packs inserted into it and both battery packs are
charged on the bike, the charging progress of both battery packs will be indicated on the display (the left-hand battery pack is being charged in the
illustration). You can tell by the flashing
indicator on the battery pack which of
the two battery packs is being charged.
Setting the Assistance Level
On the operating unit 9 you can set how much the eBike drive
assists you while pedalling. The assistance level can be
changed at any time, even while cycling.
Note: For individual versions, it is possible that the assistance
level is pre-set and cannot be changed. It is also possible that
less assistance levels are available for selection than listed
here.
If the manufacturer has configured the eBike with “eMTB
Mode” and an Intuvia on-board computer is being used on the
bicycle, “eMTB Mode” will appear briefly on the display when
the “SPORT” assistance level is selected. In “eMTB Mode”,
the assistance factor and torque are dynamically adjusted as
a function of the force you exert on the pedals. “eMTB Mode”
is only available for Performance Line CX drives.
The following assistance levels (max.) are available:
– “OFF”: The motor assistance is switched off, and the eBike
can be moved as a normal bicycle only by pedalling. The
push assistance cannot be activated in this assistance
level.
– “ECO”: Effective assistance at maximum efficiency for
maximum cruising range
– “TOUR”: Uniform assistance, for touring with long cruising
range
– “SPORT”/“eMTB”:
“SPORT”: Powerful assistance for sportive riding off road
as well as for urban traffic
“eMTB”: Optimal assistance whatever the terrain, rapid
acceleration when starting from a standstill, improved dynamics and top performance.
– “TURBO”: Maximum assistance, supporting highest ca-
dence for sportive riding
To increase the assistance level, press the “+” 12 button on
the operating unit until the desired assistance level appears in
the display b. To decrease the assistance level, press the button “–” 11.
The requested motor output is displayed in indicator a. The
maximum motor output depends on the selected assistance
level.
When the on-board computer is removed from the holder 4,
the last indicated assistance level is stored; the motor-output
indicator a remains empty.
Interaction of the eBike System with the Bicycle Gears
The bicycle gears should be used as with a normal bicycle,
even with eBike motor assistance (please observe the operating instructions of your eBike).
Independent of the type of gearing, it is recommended to
briefly interrupt the pedaling while changing gears. This
makes changing gears easier and reduces the wear of the
drive train.
By selecting the right gear, you can increase the speed and
range with the same pedaling effort.
On indicator i, each bar of the battery pack symbol is equivalent to a capacity of approx. 20 %:
The eBike battery pack is fully charged.
The eBike battery pack should be recharged.
The LEDs of the charge-control indicator on the
battery pack 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 and the on-board computer. The indicator flashes.
The capacity of the eBike battery pack is enough
for about 2 hours of lighting. This does not account
for other consumers (e.g. automatic gearbox,
charging external devices at the USB port).

Bosch eBike Systems 1 270 020 XBI | (19.4.17)
For this reason, follow the shift recommendations provided
by indications g and h on your display. If indication g is displayed, you should shift to a higher gear with lower cadence.
If indication h is displayed, you should select a lower gear with
higher cadence.
Switching bike lights on/off
In 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 with button 2.
When the lighting is switched on “Lights on” appears and
when the lighting is switched off “Lights off” appears for
approx. 1 s in text indication d. The lighting symbol c is displayed when the light is on.
Switching the bike light on and off has no effect on the back
lighting of the display.
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 lower the speed in the push-assistance function (at full output).
f The push-assistance function may only be used when
pushing the eBike. Danger of injury when the wheels of
the eBike do not have ground contact while using the pushassistance function.
To activate the push-assistance function, briefly press 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 push assistance cannot be activated in the “OFF”
assistance level.
The push assistance is switched off as soon as one of the
following occurs:
– You release the “+” 12 button;
– The wheels of the eBike are prevented from turning (e.g.
by braking or being hit by your leg);
– The speed exceeds 6 km/h.
Note: On some systems the push-assistance function can be
started directly by pressing the “WALK” button.
The push-assistance function is subject to local regulations;
the way it works may therefore differ from the description
above.
