Operation

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). Control unit power supply
If a sufficiently charged eBike battery is inserted into the bike and the eBike system is switched on, then the control unit battery is powered and charged by the eBike battery.
If the internal battery is ever totally discharged, you can charge the internal battery via the diagnostics connection (7) with a USB Type C® cable using a power bank or another suitable power source (charging voltage 5 V; charging current max. 600 mA). Always close the flap of the diagnostic connection (7) so that no dust or moisture can enter.
Switching the eBike system on/off
To switch on the eBike system, briefly press the on/ off button (1). After all, LEDs briefly light up, the state of charge of the battery is displayed in color with the
battery charge indicator (3) and the set assistance level with the (5) display. The eBike is ready to ride. The display brightness is controlled by the ambient light sensor (12). Therefore, do not cover the ambient light sensor (12). The drive is activated as soon as you start pedaling (except at assistance level OFF ). The motor output depends on the settings of the assistance level. As soon as you stop pedaling when in normal operation, or as soon as you have reached a speed of 20 mph, the eBike drive unit switches off the assistance. The drive is automatically re-activated as soon you start pedaling again and the speed is below 20 mph. To switch off the eBike system, press the on/off button (1)  briefly (< 3 s). The battery charge indicator (3) and the assistance level LED (5) go out. If no power is drawn from the eBike drive for about 5 minutes (e.g. because the eBike is not moving) and no button is pressed on the on-board computer or the control unit of the eBike, the eBike system will switch off automatically.

Battery charge indicator
The battery charge indicator (3) 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 (3) display, 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 (3) flashes.
Setting the assistance level
On the control unit using the (8) and(9) buttons, you can set how much the eBike drive assists you while pedaling. The assistance level can be changed at any time, even while cycling, and is displayed in color.

pedaling, as with a normal bicycle.
ECO| Green| Effective support with maximum efficiency, for maximum range
TOUR| Blue| Steady support, long-range for touring
eMTB/ SPORT| Purple| Optimal support whatever the terrain, rapid acceleration when
starting from a standstill, improved dynamics and top performance
TURBO| Red| Maximum support even at a high cadence, for sport cycling

The designations and configuration of the assistance levels can be preconfigured by the manufacturer and selected by the bicycle retailer.
Interaction between the eBike system and gear-shifting
The gear shifting should be used with an eBike drive 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.

Switching bike lights on/off
Before starting each journey, check that your bike lights are working correctly.
To switch on the bike lights, press the (9) button for more than 1 s.
You can use the (11) and (10) buttons to control the brightness of the LEDs on the control unit.
Switching the push assistance on/off
The push assistance aids you when pushing your
eBike. The speed of this function depends on the selected gear and can reach a maximum of 3.7 mph.
The lower the selected gear, the lower the speed of the push assistance function (at full power).
u The push assistance function must only be used when pushing the bike. 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 start walk assistance, press the (8) button for more than 1 s and keep it pressed. The battery charge indicator (3) 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 forwards.
– Push the eBike backward.
– Perform a sideways tilting movement with the eBike.
After activation, the motor begins to push and the continuously filling white bars change color to ice-blue.
If you release the (8) button, walk assistance is paused. You can reactivate walk assistance within 10 s by pressing the (8) 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 (9) button or on/off button (1) is pressed.
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 bicycle is equipped with a Bosch eBike ABS, the ABS LED (4) lights up when the eBike system starts. If the bike reaches a speed of 3.7 mph, the ABS LED (4) goes out.
In the event of a fault, the ABS LED (4) lights up together with the orange flashing assistance level
LED (5). You can acknowledge the error with the select button (2); the flashing assistance level LED (5) goes out. The ABS LED (4) continues to light up to show that the ABS system is not in operation. For details on the ABS and how it works, please refer to the ABS operating instructions.
Establishing a smartphone connection
In order to be able to use the following eBike functions, a smartphone with the eBike Flow application is required. Connection to the app occurs via a Bluetooth® connection.
Switch on the eBike system and do not start riding the bike. Begin Bluetooth® pairing by long pressing (> 3 s) the on/off button (1). Release the on/off button (1) as soon as the topmost bar on the battery charge indicator shows 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.

Lock function
The lock function can be set up and configured via the eBike Flow app. This stores a digital key on the smartphone, which is required to start the eBike system. Once the lock function is switched on, the eBike can only be put into operation if:
– the configured smartphone is switched on;
– the smartphone has sufficient battery charge;
– and the smartphone is in the immediate vicinity of the control unit.
Otherwise, motor support remains switched off.
If the key is not verified immediately, the search for the key is shown by the battery charge indicator (3) and the assistance level LED (5) flashing white. If the key is found, after flashing white the state of charge of the battery and the last set assistance level is displayed.If the key cannot be found on the smartphone, the eBike system automatically switches off. The displays on the control unit go out. Since the smartphone functions only as a contactless key when switching on, the eBike battery and onboard computer can still be used on a different, unlocked eBike.

Software updates
Software updates are transferred from the app to the control unit in the background as soon as it is connected to the app. During the update process, a green flashing on the battery charge indicator (3)  shows the progress. The system is then restarted. You can control the software updates via the eBike Flow app.
