Switching the eBike on/off
To switch on the eBike, briefly press the on/off button (12). After the starting animation, the state of charge of the eBike battery is displayed in color with the battery charge indicator (13) and the set riding mode with the (10) display. The eBike is ready to ride. The display brightness is controlled by the ambient light sensor (11). Therefore, do not cover the ambient light sensor (11). The drive is activated as soon as you start pedaling (except in the OFF riding mode). The drive power varies depending on the riding mode set.

As soon as you stop pedaling when in normal operation, or as soon as you have reached a speed of 20/28 mph, the drive switches off the assistance. The drive is automatically re-activated as soon you start pedaling again and the speed is below 20/28 mph. To switch off the eBike, briefly press the on/off but-ton (12) (< 3 s). The battery charge indicator of the eBike battery (13) and the riding mode LED (10) go out. If no power is requested from the drive for approx. 10 minutes (e.g. due to the eBike being stationary) and no button is pressed, the eBike switches off auto-matically.

Battery charge indicator of the eBike battery
In the battery charge indicator of the eBike battery (13), each ice-blue bar represents 20 % capacity and each white bar represents 10 % capacity. The topmost bar shows the maximum capacity. Example: Four ice-blue bars and one white bar are displayed. The state of charge is between 81 % and 90 %.

If capacity is low, both of the lower displays change color:

If the eBike battery is being charged, the topmost bar on the battery charge indicator of the eBike battery (13) flashes.
Outside of the eBike, the eBike battery’s state of charge is indicated by the LEDs on the eBike battery.

The designations and configuration of the riding modes can be preconfigured by the manufacturer and selected by the bicycle retailer.

Note: The available riding modes depend on the respective drive unit.

Adjusting the Riding Mode
The riding modes 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 riding mode. You can only adjust the riding modes that have been enabled by the manufacturer or dealer on your system. This may be fewer than four riding modes. In addition, restrictions in your country may mean that it is not possible to adjust a particular riding mode.

The following parameters are available for making adjustments:

• Assistance in relation to the base value of the riding 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 riding mode retains the position, name and color on all on-board computers and controls.

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 (observe the operating instructions of your eBike with regard 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
reduce wear on the powertrain. By selecting the correct gear, you can increase your speed and range while applying the same amount of force.

Switching Bicycle Lights On and Off (Mini Remote/Mini Remote Dropbar only)
Before starting each journey, check that your bike lights are working correctly.
To switch on/off the bike lights, press and hold the bicycle lights (4) button for more than 1 s.

Switching the push assistance on/off
The push assistance aids you when pushing your eBike. The maximum speed of the push assistance is 2.5 mph. The manufacturer’s default setting can be lower and may need to 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 drive unit may not be able to move the eBike or activate the roll-away lock.

To start push assistance, press and hold the push assistance button (6) for more than 1 s. The battery charge indicator of the eBike battery (13) goes out and a white moving light in the direction of travel shows that it is ready.

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

• Push the eBike forward.
• Push the eBike backward.
• Perform a sideways tilting movement with the eBike.

After activation, the drive begins to push and the continuously filling white bars change color to ice-blue. If you release the walk assistance (6) button, walk as-sistance 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 assistance 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 pedaling,
• The increase assistance level +/bicycle lights (4) button or on/off button (12) 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 (4) button. The push assistance function is subject to local regulations; the way it works may therefore differ from the description above. It can also be deactivated.

ABS – Anti-lock braking system (optional)
If the eBike is equipped with a Bosch eBike ABS from the system generation the smart system, the ABS LED (11) lights up when the eBike system starts. After moving off, the ABS internally checks its functionality and the ABS LED (11) goes off. In the event of a fault, the ABS LED (11) lights up, together with the orange flashing riding mode LED (10). You can acknowledge the fault using the select button (5) on the Mini Remote/Mini Remote Dropbar (1) operating unit or with the mode button (14) on the System Controller (2) operating unit. The flashing riding mode LED (10) will go out. While the ABS LED (11) is lit up, the ABS is not in operation.
For details on the ABS and how it works, please refer to the ABS operating instructions.

Establishing a Smartphone Connection with the System Controller

In order to be able to use the following eBike functions, a smartphone with the eBike Flow app is required. Connection to the app occurs via a Bluetooth® connection.
Switch on the eBike and wait for the starting animation. Do not ride the eBike. Begin Bluetooth® pairing by pressing and holding (> 3 s) the on/off button (12). Release the on/off button (12) as soon as the topmost bar on the battery charge indicator of the eBike battery (13) indicates the pairing process by flashing blue. Confirm the connection request in the app.

Activity tracking
In order to record activities, it is necessary to register and log into the eBike Flow app. To record activities, you must consent to the storage of your location data in the app. Without this, your activities cannot be recorded in the app. For location data to be recorded, you must be logged in as the user.
