Operation

Symbols and their Meaning

Start-up

Prerequisites
The eBike system can only be activated when the following requirements are met:

• A sufficiently charged battery is inserted (see battery 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 onboard computer 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 if you are using the push-assistance function or if the assistance level is set to OFF). 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 25/45 km/h, the eBike drive switches off the assistance. The drive is automatically reactivated as soon you start pedaling again and the speed is below 25/45   km/h.

The following options are available for switching off the eBike system:

• Press the on/off button (1) of the onboard computer.
• Switch off the eBike battery using its on/off button (bicycle manufacturer-specific solutions are possible when there is no access to the battery on/off button; see the bicycle manufacturer operating instructions).

The system shuts down after being switched off. This takes approximately 3 seconds. It cannot be switched back on until the shutdown has been completed.

If the eBike is not moved for approx. 10 min 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 onboard computer are empty, 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.

The energy supply of the on-board computer
The onboard computer is supplied with voltage by two CR2016 button cells.

Changing the batteries (see figure A)
If the onboard computer shows LOW BAT on the display, remove the onboard computer from the handlebars by unscrewing the fastening screw (3) of the onboard computer. Open the battery compartment cover (10) using a suitable coin, remove the used batteries and insert new CR2016 batteries. You can obtain the 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 onboard 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 in this function depends on the selected gear and can reach a maximum of 6 km/h. 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 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 onboard computer. After activation, press the **+** button within 3 s and keep it pressed. The eBike drive
is switched on.

Note: The push assistance cannot be activated at assistance 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 6 km/h.

The push assistance function is subject to local regulations; the way it works may therefore differ from the description above, or the function may even be deactivated completely.

Setting the assistance level

You can set the level at which the eBike drive assists you while pedaling on the onboard computer. 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.

The following assistance levels are available as a maximum:

• OFF: Motor assistance is switched off. The eBike can just be moved by pedaling, as with a normal bicycle. The push assistance cannot be activated at this assistance level.

• ECO: Effective assistance with maximum efficiency, for maximum range

• TOUR: Steady assistance, long-range for touring

• SPORT/eMTB:
  SPORT: Powerful assistance, for mountain biking and cycling in urban traffic
  eMTB: Optimum assistance whatever the terrain, rapid acceleration when starting from a standstill, improved dynamics, and top performance (eMTB only available in combination with the drive units BDU250P CX, BDU365, BDU450 CX, and BDU480 CX. A software update may be required.)

• TURBO: Maximum assistance even at high pedaling speeds, for sports cycling

To increase the assistance level, briefly press the button + (6) on the onboard computer repeatedly until the required assistance level appears on the indicator (i). To
decrease the assistance level briefly press the button – (5).
If the display is set to TRIP, TOTAL, or RANGE, the selected assistance level will only be superimposed briefly (for approx. one second) on the display when switching over.

Switching bicycle lights on/off

For the model which has the bike lights powered by the eBike system, a medium- length press of the button **+** will switch on the front and rear lights simultaneously. To switch off the bike lights, press and hold the button **+**.
The lighting symbol (h ) is displayed when the light is on. Check that your bike lights are working correctly before every use.
The onboard computer saves the light status and activates this saved status accordingly after a restart.
Switching the bike lights on and off has no effect on the backlighting of the display.

Displays and configurations of the on-board computer

Battery charge indicator

The battery charge indicator (g) displays the eBike battery’s state of charge. The state of charge of the eBike battery can also be checked on the LEDs of the battery itself. In the indicator (g) , each bar in the battery symbol represents approximately 20 % capacity:

| The eBike battery is fully charged.
---|---
| The eBike battery should be recharged.
| The LEDs of the battery charge indicator on the 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. The indicator flashes.

The capacity of the eBike battery is enough for about two hours of lighting.

Speed and distance indicators

The speedometer (a) always displays the current speed.
Indicator (i) always displays the last setting as a standard. Repeated medium-length presses of the button – will display the trip distance TRIP, the total distance TOTAL, and the range of the battery RANGE one after the other. (Briefly pressing the button – will decrease the assistance level.)

To reset the trip distance TRIP, select the trip distance TRIP and simultaneously press and hold 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.

To reset the range of the battery RANGE, select the battery range RANGE and simultaneously press and hold 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 the button – and briefly pressing the on/off button (1).
The versions of the subsystems and their model part numbers can be displayed for the purposes of servicing, provided the subsystems divulge this information (dependent on the subsystem). With the system switched off, simultaneously press the buttons – and + and then press the on/ off button (1).
The USB port is reserved for connecting diagnostic systems. The USB port does not have any other function.
The USB connection must always be completely sealed with the protective cap (8).

Safety instructions

Read all the safety information and instructions. Failure to observe the safety information and follow instructions may result in electric shock, fire, and/or serious injury.

Save all safety warnings and instructions for future reference.

The term battery is used in these instructions to mean all original Bosch eBike rechargeable battery packs.
Do not attempt to change – and especially increase – the power of your drive or the maximum speed that it supports. Doing this may put yourself and others at risk, and you may also breach statutory regulations.
Do not make any modifications to your eBike system or fit any other products that might increase the performance of your eBike system. Doing so will generally reduce the service life of the system and risk damaging the drive unit and the bike. You also run the risk of losing the guarantee and warranty claims on the bicycle 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 that can be attributed to manipulation of the bicycle.
Do not open the drive unit yourself. The drive unit must only be repaired by qualified personnel using only original spare parts. This will ensure that the safety of the drive unit is maintained. Unauthorized opening of the drive unit will render warranty claims null and void.
All components fitted to the drive unit and all other components of the eBike drive (e.g. chainring, chainring receptacle, pedals) must only be replaced with identical components or components that have been specifically approved by the manufacturer for your eBike. This will protect the drive unit from overloading and becoming damaged.
Remove the battery from the eBike before beginning work (e.g. inspection, repair, assembly, maintenance, work on the chain, etc.) on the eBike, transporting it with a car or airplane, or storing it. Unintentional activation of the eBike system poses a risk of injury.
The eBike system can be activated by pushing the eBike backward or by turning the pedals backward.
The 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.
When the push assistance is activated, the pedals may turn at the same time. When the push assistance function is activated, make sure that there is enough space between your legs and the turning pedals to avoid the risk of injury.
On sections of the drive, temperatures >60 °C may occur in extreme conditions, e.g. when carrying consistently high loads at low speed when riding up hills or transporting loads.
  After a ride, do not allow your unprotected hands or legs to come into contact with the housing of the drive unit. Under extreme conditions, such as continuously high torques at low travel speeds, or when riding up hills or carrying loads, the housing may reach a very high temperature. The temperature that the drive unit housing may reach is influenced by the following factors:
– Ambient temperature
– Ride profile (route/gradient)
– Ride duration
– Assistance modes
– User behavior (personal effort)
– Total weight (rider, eBike, luggage)
– Motor cover on the drive unit
– Heat dissipation properties of the bicycle frame
– Type of drive unit and type of gear-shifting
Use only original Bosch batteries that the manufacturer has approved for your eBike. Using other batteries can lead to injuries and pose a fire hazard. Bosch accepts no liability or warranty claims if other batteries are used.
Observe all national regulations which set out the approved use of eBikes.
Read and observe the safety warnings and directions contained in all the eBike system operating instructions and in the operating instructions of your eBike.

Privacy notice

When you connect the eBike to the Bosch DiagnosticTool, data about the eBike drive unit (e.g. energy consumption, temperature, etc.) is transferred to Bosch eBike Systems (Robert Bosch GmbH) for the purpose of product improvement.

Assembly

Inserting and removing the battery

For inserting and removing the eBike battery in/from the eBike, please read and observe the battery operating instructions.

Checking the speed sensor (see figure A)

Speed sensor (standard)
The speed sensor (2) and its spoke magnet (3) must be fitted such that the spoke magnet moves past the speed sensor at a distance of at least 5 mm and at most 17 mm with each rotation of the wheel.
Note: If the distance between the speed sensor (2) and the spoke magnet (3) is too small or too large, or if the speed sensor (2) is not properly connected, the speedometer display will fail and the eBike drive unit will operate in emergency mode.

Should this occur, loosen the screw of the spoke magnet (3) and fasten the spoke magnet to the spoke such that it runs past the marking on the speed sensor at the correct clearance. If the speed is still not being indicated on the speedometer display after doing this, please contact an authorized bicycle dealer.

Speed sensor (slim)

The speed sensor (slim) (4) and its magnet (5) must be mounted in such a manner that the magnet, after a turn of the wheel, moves past the speed sensor with a clearance of at least 2 mm, yet no more than 8 mm.

If any structural changes are made, the correct distance between the magnet and the sensor must be complied with (see figure  A).
Note: Make sure you do not damage the sensor or the sensor holder when fitting or removing the rear wheel.
