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 op-erating 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 on-board 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 pedalling (except if you are using the push-assistance function or if the assist-ance level is set to OFF). The motor output depends on the settings of the assistance level on the on-board computer. As soon as you stop pedalling 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 automat-ically reactivated as soon you start pedalling 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 on-board computer.
• Switch off the eBike battery using its on/off button (bi-cycle manufacturer-specific solutions are possible when there is no access to the battery on/off button; see the bi-cycle manufacturer operating instructions).

The system shuts down after being switched off. This takes approximately 3 seconds. It cannot be switched back on un-til shutdown has been completed.n 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. If the batteries of the on-board computer are empty, you can still switch on your eBike using the bike’s battery. It is, however, recommended that you replace the internal bat-teries as soon as possible in order to avoid damage.

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

Changing the batteries (see figure A)
If the on-board computer shows LOW BAT on the display, remove the on-board computer from the handlebars by un-screwing the fastening screw (3) of the on-board computer. Open the battery compartment cover (10) using a suitable coin, remove the used batteries and insert new CR2016 bat-teries. You can obtain the batteries recommended by Bosch from your bicycle dealer. When inserting the batteries, ensure that the polarity is cor-rect. Close the battery compartment again and fasten the on-board computer to your eBike’s handlebars using the fasten-ing 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 on-board 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 pedalling on the on-board 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 pedalling, 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 dy-namics 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 pedalling speeds, for sport cycling

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 repres-ents 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 standard. Re-peated 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 but-tons + 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 kilometres to miles by holding down the button – and briefly pressing the on/off button (1). The versions of the subsystems and their model part num-bers can be displayed for the purposes of servicing, provided the subsystems divulge this information (depend-ent on the subsystem). With the system switched off, simul-taneously 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).

• The eBike system must be switched off.
• The information is shown as scrolling text.
• The display must be switched off.

Error code display

The eBike system’s components are continuously and auto-matically monitored. If an error is detected, the correspond-ing error code is displayed on the on-board computer. The drive may be automatically shut down, depending on the type of error. However, if you wish to continue cycling, you

Maintenance and servicing

Do not use any detergents. Have your eBike system checked by an expert at least once a year (including mechanical parts, up-to-dateness of system software). The bicycle manufacturer or dealer can also store a distance travelled for the service date in the system. In this case, the on-board computer will show you that the service date is due by displaying (f) . Please have your eBike serviced and repaired by an author-ised bicycle dealer.
