Safety instructions
Read all the safety information and
instructions. Failure to observe the
safety information and follow instruc-
tions may result in electric shock, fire
and/or serious injury.
Save all safety warnings and instructions for fu-
ture reference.
The term eBike battery used in these operating in-
structions refers to all original Bosch eBike batteries.
uRead and observe the safety warnings and in-
structions in all operating instructions of the
eBike system and your eBike.
uOnly charge the on-board computer with USB
power source (5V, 500mA max) and USB cable
rated at least 500mA. Using USB power source or
USB cable not appropriately rated for the applica-
tion may result in fire, explosion or personal injury.
uCharge the on-board computer in temperatures
above +32degreesF (0degreesC) and below
+104degreesF (40degreesC). Store on-board
computer in locations where temperatures will
not exceed 104degreesF (40degreesC). This is
important to prevent serious damage to the battery
in the on-board computer.
uDo not expose on-board computer to fire or ex-
cessive temperature. Exposure to fire or tempera-
ture above 212 °F (100 °C) may cause explosion.
uDo not recharge the on-board computer (via
USB port) in damp or wet environment. Water
entering on-board computer may result in electric
shock or fire.
uNever submerge on-board computer in fluid of
any kind or allow fluid to enter them. Corrosive
or conductive fluid (such as seawater or industrial
chemical or bleach containing products, etc.) can
cause short circuit which may result in fire, per-
sonal injury and property damage.
uBattery leakage may occur under extreme usage
or temperature conditions. Avoid contact with
skin and eyes. The battery liquid is caustic and
could cause chemical burns to tissues. If liquid
comes in contact with skin, wash quickly with soap

ternal USB power source. Carpeting and other
heat insulating surfaces block proper air circulation
which may cause overheating of the on-board com-
puter. If smoke or melting of the on-board com-
puter is observed, unplug the external USB power
source immediately and do not use the on-board
computer. Contact customer service immediately.
uBefore each use, check the on-board computer,
cable and plug. If damage is detected, do not use
the on-board computer. Damaged on-board com-
puter, charging cables and plugs increase the risk
of a fire, explosion and personal injury.
uDo not use the on-board computer as a handle.
Lifting the eBike up by the on-board computer can
cause irreparable damage to the on-board com-
puter.
uDo not disassemble on-board computer. No user
serviceable part inside. Incorrect reassembly or
damage may result in fire or explosion.
uDo not allow yourself to be distracted by the dis-
play of the on-board computer. If you do not con-
centrate exclusively on the traffic around you, you
risk being involved in an accident. If you want to
change any settings on the on-board computer
other than the assistance level, always stop before
entering the relevant data.

you can always control the eBike and hold it se-
curely. The push assistance can be suspended un-
der certain conditions (e.g. obstacle on the pedal
or accidentally slipping off the button of the operat-
ing unit). The eBike can suddenly move backwards
towards you or start to tip. This poses a particular
risk for the user if there is an additional load. When
using the push assistance on the eBike, do not
place the eBike in situations in which you cannot
hold the eBike by yourself.

facturer. The separate operating instructions de-
scribe how to operate the electronic gear-shifting sys-
tems.
Energy supply of the on-board computer
If the on-board computer is in the holder(4), a suffi-
ciently charged eBike battery is inserted into the
eBike and the eBike system is switched on, then the
on-board computer battery is powered by the eBike
battery.
If the on-board computer is removed from the
holder(4), the energy is supplied via an internal bat-
tery of the on-board computer. If the internal battery
of the on-board computer is weak when the on-board
computer is switched on, <Attach to bike> will ap-
pear on the text indicator(d) for 3seconds. The on-
board computer will then turn off again.
To charge the internal battery of the on-board com-
puter, put the on-board computer back in the
holder(4) (when an eBike battery is inserted in the
eBike). Switch the eBike battery on by its on/off but-
ton (see operating instructions for the eBike battery).

Powering external devices from the USB
port
The USB port can be used to operate or charge most
devices that can be powered via USB (e.g. various
mobile phones).
Charging requires the on-board computer to be
mounted and a sufficiently charged eBike battery to
be inserted in the eBike.
Open the protective cap(8) for the USB port on the
on-board computer. Use the Micro A–Micro B USB
charging cable (available from your Bosch eBike
dealer) to connect the USB port of the external device
to the USB port(7) of the on-board computer.
Bosch eBike Systems 1 270 U20 XBI | (14.03.2023)

English – 10
Once the electrical load has been disconnected, the
USB port must be carefully resealed with the protec-
tive cap(8).
uA USB connection is not a watertight plug con-
nection. When cycling in wet conditions, ensure
no external devices are connected and that the
USB port is fully covered by the protective
cap(8).
Attention: Any electrical devices connected can re-
duce the range of the eBike.
Switching on/shutting down the on-board
computer
To switch on the on-board computer, briefly press
the on/off button(5). The on-board computer can
also be switched on when it is not inserted in the
holder (if the internal battery of the on-board com-
puter is sufficiently charged).
To switch off the on-board computer, press the on/
off button (5).
If the on-board computer is not inserted in the holder,
it automatically switches off after 1minute to save en-
ergy if no button is pressed.
uIf you are not going to be using your eBike for
several weeks, remove the on-board computer
from its holder. Store the on-board computer in a
dry environment at room temperature. Regularly
recharge the on-board computer's internal battery
(at least every three months).
Battery charge indicator of the eBike
battery
The battery charge indicator of the eBike battery(i)
displays the state of charge of the eBike battery, not
that of the on-board computer's internal battery. The
eBike rechargeable battery's state of charge is also in-
dicated by the LEDs on the eBike rechargeable bat-
tery itself.
Each bar of the battery symbol on the indicator (i)
represents approximately20% of the capacity:
The eBike battery is fully charged.
The eBike battery should be recharged.
The LEDs of the battery charge indicator
on the eBike battery go out. 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 is enough for about 2 hours
of lighting. This does not account for other
consumers (e.g. automatic gearbox,
charging external devices from the USB
port).
If the on-board computer is removed from the
holder(4), the state of charge that was last displayed
for the eBike battery is saved. If an eBike is powered
by two eBike batteries, the battery charge indicator
for the eBike battery(i) will display the state of
charge of both eBike batteries.

MPH
KM/H
If an eBike has two eBike batteries
inserted into it and both eBike bat-
teries are charged on the bike, the
charging progress of both eBike bat-
teries will be indicated on the display
(the left-hand eBike battery pack is
being charged in the illustration).
You can also tell by the flashing indi-
cator on the eBike battery which of
the two eBike batteries is being
charged.
Setting the assistance level
On the control unit(9), you can set how much the
drive assists you while pedaling. The assistance 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.
1 270 U20 XBI | (14.03.2023) Bosch eBike Systems

English – 11
The following assistance levels are available as a max-
imum:
–OFF: Drive assistance is switched off. The eBike
can only 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/TOUR+:
TOUR: Steady support, for long-range touring
TOUR+: Dynamic support for natural and sporty
driving (only in conjunction with eMTB)
–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

To increase the assistance level, press the +but-
ton(12) on the operating unit repeatedly until the re-
quired assistance level appears on the indicator(b).
To decrease the assistance level, press the –but-
ton(11).
The requested drive power appears on the dis-
play(a). The maximum drive power depends on the
selected assistance level.
When the on-board computer is removed from the
holder(4), the assistance level that was last dis-
played is saved; the drive power indicator(a) re-
mains empty.
Interaction of the drive unit with the gear-
shifting
You should shift through gears on an eBike in the
same manner as when using a normal bicycle (ob-
serve the operating instructions of your eBike with re-
gard to this point).
Irrespective of the type of gear shifting, it is advisable
that you briefly reduce the pressure on the pedals
when changing gear. This will aid gear shifting and re-
duce wear on the powertrain.
By selecting the correct gear, you can increase your
speed and range while applying the same amount of
force.
For this reason, follow the gear change recommenda-
tions provided by the indicators (g) and (h) on your
display. If indicator (g) is displayed, you should
change to a higher gear with lower cadence. If indica-
tor (h) is displayed, you should select a lower gear
with higher cadence.
Switching bike 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 lights button(2).
Before starting each journey, check that your bike
lights are working correctly.
When the lighting is switched on, <Lights on> ap-
pears and when the lighting is switched off, <Lights
off> appears for approx. 1s on the text indicator (d).
The lighting symbol (c) is displayed when the light is
on.
The on-board computer saves the light status and ac-
tivates this saved status accordingly after a restart.
Bosch eBike Systems 1 270 U20 XBI | (14.03.2023)

English – 12
Switching the bike lights on and off has no effect on
the backlighting of the display.
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.
uThe push assistance function must only be used
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-
vation, press the + button within 10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(12);
– 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.
Displays and settings of the on-board computer
Speed and distance indicators
The speedometer(f) always displays the current
speed.
You can choose from the following functions in the
function display (combination of text indicator(d)
and value indicator(e)):
–<Clock>: Current time
–<Max. speed>: Maximum speed achieved since
the last reset
–<Avg. speed>: Average speed achieved since the
last reset
–<Trip time>: Journey time since the last reset
–<Range>: Estimated range of the available battery
charge (at constant conditions such as assistance

–<Odometer>: Total distance traveled with the
eBike (cannot be reset)
–<Trip distance>: Distance traveled since the last
reset
To switch between display functions, press
theibutton (1) on the on-board computer or
theibutton(10) on the operating unit repeatedly un-
til the required function is displayed.
To reset the <Trip distance>, <Trip time> and
<Avg. speed>, switch to one of these three functions
and then press and hold the RESET button (6) until
the indicator is set to zero. This will also reset the val-
ues of the other two functions.
To reset the <Max. speed>, switch to this function
and then press and hold the RESET button (6) until

Transport
uIf you transport your eBike attached to the out-
side of your car, e.g. on a bike rack, remove the
on-board computer and the eBike battery to
avoid damaging them.
WARNING
uAlways remove the battery pack from the bicy-
cle before transporting the bicycle on a vehicle
bike rack. Failure to remove the battery pack when
using a vehicle bike rack can lead to death or seri-
ous injury. The battery may detach during transport
and cause an accident to following vehicles.
uAlways use an approved and compatible bicycle
rack when transporting your eBike. The Bosch
drive system adds weight to the bicycle. Refer to
your bicycle rack manual to be sure your eBike is
compatible. Overloading a bike rack can result in
death or serious injury.
uUse proper lifting techniques as electric bikes
are generally heavier than bicycles.
Ship batteries only when the housing is undamaged.
Tape or mask off open contacts and pack up the bat-
tery in such a manner that it cannot move around in
the packaging. Inform your parcel service that the
package contains dangerous goods. Please also ob-
serve possibly more detailed national regulations. Al-
ways check state and federal regulations before at-
tempting to ship your battery.
If you have any questions about transporting the
eBike batteries, contact an authorized bicycle dealer.
You can also order suitable transport packaging from
the dealer.

Maintenance/cleaning
WARNING
uDo not open any of the components. Service
should only be carried out at an authorized
Bosch eBike dealer. Failure to follow above warn-
ing can cause death or serious injury. Refer to your
bicycle manual or component manual for all non-
Bosch drive system components.
uAlways remove the battery pack before per-
forming any bicycle inspection, maintenance or
repair. Failure to remove the battery pack before
performing bicycle inspection, maintenance or re-
pair can lead to serious injury.
uIf you suspect that something is loose, do not
ride your bike. See your Bosch eBike dealer, only a
qualified service provider should perform work on
your Bosch Drive System. All nuts, bolts, screws re-
quire the correct tightening force. Too little force
and the fastener may not hold securely. Too much
force and the fastener can strip threads, stretch,
deform or break. Either way, incorrect tightening
force can result in component failure, which can
cause you to lose control and fall.
uDo not paint any components of the Bosch drive
system as they may cause premature failure of
the component.
Taking care of your eBike
Please observe the operating and storage tempera-
tures of the eBike components. Protect the drive unit,
on-board computer and eBike battery against ex-
treme temperatures (e.g. from intense sunlight with-
out adequate ventilation). Extreme temperatures can
cause the components (especially the eBike battery)
to become damaged.
Have your eBike checked by an expert at least once a
year (including mechanical parts, up-to-dateness of
system software).
Please have your eBike serviced and repaired by an
authorized bicycle dealer.
The bike retailer can also schedule the service based
on a mileage and/or a time period. In this case, the
on-board computer displays a message telling you
when the service date is due each time it is switched
on.
Cleaning
uDo not submerge your eBike components in wa-
ter, or wash with pressurized hose. Your Bosch
drive unit is designed to be water tight to rain water
or non-pressure hose washing.
Keep all components of your eBike clean, especially
the battery pack contacts and corresponding holder
contacts. All components including the drive unit may
not be immersed in water or cleaned with a high-pres-
sure cleaner. Clean them carefully with a soft, damp
cloth (using only mild soap and water).
After-sales service and advice on using
products
If you have any questions about the eBike and its
components, contact an authorized bicycle retailer.
For contact details of authorized bike dealerships,
please visit www.bosch-ebike.com.
Please contact an authorized bicycle dealer if the
eBike battery is no longer working.
