Safety instructions

Read all the safety and general instructions. Failure to observe the safety and general instructions may result in electric shock, fire and/or serious injury. Save all safety warnings and instructions for future reference. The term eBike battery is used in these instructions to mean all original Bosch eBike rechargeable battery packs from the system generation the smart system. The terms drive and drive unit used in these operating instructions refer to the original Bosch drive units from the system generation the smart system.

Read and observe the safety warnings and directions contained in all the eBike system operating instructions and in the operating instructions of your eBike.
Do not attempt to secure the display or operating unit while riding.
Do not allow yourself to be distracted by the operating unit’s display. If you do not focus exclusively on the traffic, you risk being involved in an accident. If you want to change settings on your operating unit, beyond just changing the assistance level, stop cycling to do so.
Set the display brightness so that you can adequately see important information such as speed and warning symbols. Incorrectly set display brightness may lead to dangerous situations.
Do not use the operating unit as a handle. If you lift up the eBike by the operating unit, you may cause irreparable damage to the operating unit.
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.
When using the walk assistance, make sure that you can control the eBike and that you can hold it securely at all times. Under certain circumstances, the walk assistance may stop (e.g. if the pedals hit an obstacle or if you accidentally let go of the button on the operating unit). The eBike may suddenly move backwards onto you or tip up. This presents a risk for the user particularly if there is additional load on the eBike. When using the walk assistance, do not bring the eBike into situations in which you cannot hold the eBike using your own strength.

Operation

Requirements
The eBike can then only be switched on when the following requirements are met:

A sufficiently charged eBike battery is inserted (see operating instructions for the eBike battery from the system generation the smart system).
The speed sensor is connected properly (see operating instructions for the drive unit from the system generation the smart system).

Before riding off, ensure that the buttons on the operating unit are within easy reach. We recommend that you align the unit so that the plus/minus button level is perpendicular to the floor.

Operating unit power supply
If a sufficiently charged eBike battery is inserted into the eBike and the eBike is switched on, then the internal operating unit battery is powered and charged. If the state of charge of the internal operating unit battery is very low, you can charge it via the diagnostics connection (8) with a USB Type-C® cable using a power bank or an-other suitable power source (charging voltage 5 V; charging current max. 600 mA). Always close the flap of the diagnostics connection (8) so that no dust or moisture can enter.

Switching the eBike On and Off
To switch on the eBike, briefly press the on/off button (1). The eBike is ready to ride once the start-up animation is complete. The display brightness is controlled by the ambient light sensor (3). Therefore, do not cover the ambient light sensor (3). The drive is activated as soon as you start pedalling (except at assistance level OFF). The drive power varies depending on the assistance level set. 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 drive switches off the assistance. The drive is automatically reactivated as soon you start pedalling again and the speed is below 25/45 km/h. To switch off the eBike, briefly press the on/off button (1)(< 3 s). If no power is drawn from the drive for about 10 minutes (e.g. because the eBike is not moving) and no button is pressed, the eBike will switch off automatically.

Quick Menu
Selected settings are displayed on the quick menu. These settings can also be changed while riding. You can access the quick menu by pressing and holding (> 1 s) the select button . It cannot be accessed from the status screen.
The following settings can be changed via the quick menu:

Selecting the Assistance Level
You can set how much the eBike drive assists you while pedalling by pressing the increase assistance level + (5) and reduce assistance level – (6) buttons on the operating unit. The assistance level can be changed at any time, even while cycling, and is displayed in colour.

Note: The available modes depend on the respective drive unit.
The designations and configuration of the assistance levels can be preconfigured by the manufacturer and selected by the bicycle re-tailer.

Adapting the Assistance Level
The assistance level can be adapted within certain limits using the eBike Flow app. This gives you the option of adjusting your eBike to your personal requirements. It is not possible to create a completely new mode. You can only adjust the modes that have been enabled by the manufacturer or dealer on your system. This may be fewer than four modes. In addition, restrictions in your country may mean that it is not possible to adjust a particular mode.

The following parameters are available for making adjustments:

Assistance in relation to the base value of the mode (within the legal requirements)
Drive response
Top limit speed (within the legal requirements)
Maximum torque (within the limits of the drive)

Note: Please ensure that your modified mode retains the position, name and colour on all on-board computers and controls.

Interaction between the drive unit and gear- shifting
The gear shifting should be used with an eBike in the same way as with a normal bicycle (observe the operating instructions of your eBike on 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 reduce 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 recommendations displayed on your on-board computer.

Switching bike lights on/off
Check that your bike lights are working correctly before every use. To switch on the bike lights, press and hold the bicycle lights (5) button for more than 1 s.

Switching the Walk Assistance On and Off
The walk assistance makes it easier to push your eBike. The maximum speed of the walk assistance is 4 km/h. The manufacturer can adjust the default so that it is lower and, if necessary, it can also be adjusted by the bicycle retailer.
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. If the selected gear is too high, the eBike’s drive unit cannot move and the roll-away lock cannot engage. To start walk assistance, press the walk assistance (6) button for more than 1 s, keep it pressed and follow the instructions on the display.

To activate walk assistance, one of the following actions must occur within the next 10 s:

Push the eBike forwards.
Push the eBike backwards.
Perform a sideways tilting movement with the eBike. After activation, the drive begins to push and the indicator on the display changes.

If you release the walk assistance (6) button, walk assistance is stopped. You can reactivate walk assistance within 10 s by pressing the walk assistance (6) button. If you do not reactivate walk assistance within 10 s, walk as-sistance automatically switches off.

Walk assistance is always ended if:

The rear wheel jams,
The bicycle cannot move over ridges,
A body part is blocking the bike crank,
An obstacle continues to turn the crank,
You start pedalling,
The increase assistance level +/bicycle lights (5) button or on/off button (1) is pressed.

Walk assistance has a roll-away lock, i.e. even after walk assistance has been used, rolling backwards is actively curbed by the drive for a few seconds, and you cannot push the eBike backwards or can only do so with difficulty.
The roll-away lock is immediately deactivated by pressing the increase assistance level +/bicycle lights (5) button. 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.

ABS – anti-lock braking system (optional)
If the eBike is fitted with a Bosch eBike ABS from the system generation the smart system, the ABS symbol lights up when the eBike system starts. After moving off, the ABS internally checks its functionality and the ABS symbol goes off. In the event of an error, the ABS symbol lights up and a message appears on the display. This means that the ABS is in-active. You can press the select button (4) to acknowledge the error and the ABS error message disappears. The ABS symbol appears in the status bar to notify you that the ABS is still switched off. For details on the ABS and how it works, please refer to the ABS operating instructions.
