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 ref-erence.
The term battery is used in these instructions to mean all original Bosch eBike rechargeable battery packs.

• Read and observe the safety warnings and directions contained in all the eBike system operating instruc-tions and in the operating instructions of your eBike.
• Do not attempt to secure the display or operating unit while riding.
• 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 func-tion 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 as-sistance 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.
• Do not stand your bicycle upside down on its handle-bars and saddle if the operating unit or its holder pro-trude from the handlebars. This may irreparably dam-age the operating unit or the holder.
• Do not connect a charger to the eBike system if the eBike system displays a critical error. This may result in damage to your battery. The battery may catch fire, thereby resulting in serious burns and other injuries.
• The operating unit features a wireless interface. Local operating restrictions, e.g. in aeroplanes or hospitals, must be observed.
• Caution! When using the operating unit with Bluetooth®, this may cause interference that affects other devices and systems, aeroplanes and medical devices (e.g. pace-makers, hearing aids). Likewise, injury to people and an-imals in the immediate vicinity cannot be excluded en-tirely. Do not use the operating unit with Bluetooth® in the vicinity of medical devices, petrol stations, chemical plants, areas with a potentially explosive atmosphere or on blast sites. Do not use the operating unit with Bluetooth® in aeroplanes. Avoid operation near your body for extended periods.
• The Bluetooth® word mark and logos are registered trade-marks owned by Bluetooth SIG, Inc. and any use of such marks by Bosch eBike Systems is under licence.
• Observe all national regulations which set out the ap-proved use of eBikes.

Operation

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).

Operating unit power supply
If a sufficiently charged eBike battery is inserted into the eBike and the eBike system is switched on, then the operat-ing unit battery is powered and charged by the eBike bat-tery. If the state of charge of the internal battery is very low, you can charge the internal battery via the diagnostics connec- tion (7) 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 (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 but-ton (1). After the starting animation, the state of charge of the battery is displayed in colour with the battery charge in-dicator (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 pedalling (except at assistance level OFF). The motor output depends on the settings of the assistance level. 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. To switch off the eBike system, press the on/off button (1) briefly (< 3 s). The battery charge indicator (3) and the as-sistance level LED (5) go out. If no power is drawn from the eBike drive for about 10 minutes (e.g. because the eBike is not moving) and no button is pressed on the on-board computer or the con-trol unit of the eBike, the eBike system will switch off auto-matically.

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 % capa-city and each white bar represents 10 % capacity. The top-most bar shows the maximum capacity.

Example : Four ice-blue bars and one white bar are dis-played. The state of charge is between 81 % and 90 %. If capacity is low, both of the lower displays change colour:

Bar Capacity

If the eBike battery is being charged, the topmost bar on the battery charge indicator (3) flashes.

Setting the assistance level
You can set how much the eBike drive assists you while ped-alling on the operating unit using the (8) and (9) buttons. The assistance level can be changed at any time, even while cycling, and is displayed in colour.

OFF| Motor support is switched off. The eBike can just be moved by pedalling, as with a normal bi-

cycle.

---|---
ECO| Effective support with maximum efficiency, for

maximum range

TOUR| Steady support, long range for touring
TOUR+| Dynamic assistance for natural, sporty cycling
eMTB / SPORT| Optimal support whatever the terrain, rapid ac- celeration when starting from a standstill, im-

proved dynamics and top performance

TURBO| Maximum support even at a high cadence, for

sport cycling

AUTO| The support is dynamically adapted to the rid-

ing situation.

RACE| Maximum support on the eMTB racetrack; very direct response and maximum “Extended Boost” for the best possible performance in

competitive situations

CARGO A)| Steady, powerful support, so as to be able to

safely transport heavy weights

The CARGO assistance level can have an additional description. 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 us-ing the eBike Flow app. This gives you the option of adjust-ing 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 manu-facturer or dealer on your system. This may be fewer than 4 modes. Due to technical limitations, you cannot adjust the eMTB and TOUR+ 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 adjust-ments:

• 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)

The parameters are dependent on each other and influence each other. For example, it is not fundamentally possible to simultaneously set a low torque value and high assistance.

Note : Please ensure that your modified mode retains the po-sition, name and colour on all on-board computers and con-trols.

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 in-structions 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
Check that your bike lights are working correctly before every use. 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 bright-ness of the LEDs on the operating unit.

Switching the push assistance on/off
The walk assistance makes it easier to push your eBike. The speed in this function depends on the selected gear and can reach a maximum of 4 km/h. 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 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 backwards.
• Perform a sideways tilting movement with the eBike.

After activation, the motor begins to push and the continu-ously filling white bars change colour to ice-blue. If you release the (8) button, walk assistance is stopped. You can reactivate walk assistance within 10 s by pressing the (8) 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 (9) button or on/off button (1) is pressed.

Walk assistance has a roll-away lock, i.e. even after walk as-sistance has been used, rolling backwards is actively curbed by the drive system for a few seconds, and you cannot push the eBike backwards or can only do so with difficulty. 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 bicycle is equipped with a Bosch eBike ABS, the ABS LED (4) lights up when the eBike system starts. After moving off, the ABS internally checks its functionality and the ABS LED goes off. 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 flash-ing assistance level LED (5) goes out. While the ABS LED (4) 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
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 system and do not start riding the eBike. Begin Bluetooth® pairing by pressing and holding (> 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.
