Safety instructions
Read all the safety information and in-structions. Failure to observe the safety in-formation 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 change – and especially increase –the power of your drive or the maximum speed that it supports. Doing this may put yourself and others at risk, and you may also breach statutory regulations.
-
Do not make any modifications to your eBike system or fit any other products that might increase the per-formance of your eBike system. Doing so will generally reduce the service life of the system and risks damaging the drive unit and the bike. You also run the risk of losing the guarantee and warranty claims on the bicycle you have purchased. By handling the system improperly you are also endangering your safety and that of other road users, thus running the risk of high personal liability costs and possibly even criminal prosecution in the event of ac-cidents that can be attributed to manipulation of the bi-cycle.
-
Do not open the drive unit yourself. The drive unit must only be repaired by qualified personnel using only original spare parts. This will ensure that the safety of the drive unit is maintained. Unauthorised opening of the drive unit will render warranty claims null and void.
-
All components fitted to the drive unit and all other components of the eBike drive (e.g. chainring, chain-ring receptacle, pedals) must only be replaced with identical components or components that have been specifically approved by the manufacturer for your eBike. This will protect the drive unit from overloading and becoming damaged.
-
Remove the battery from the eBike before beginning work (e.g. inspection, repair, assembly, maintenance, work on the chain, etc.) on the eBike, transporting it with a car or aeroplane, or storing it. Unintentional ac-tivation of the eBike system poses a risk of injury.
On sections of the drive, temperatures 60 °C may occur in extreme conditions,e.g. when carrying consistently high loads at low speed when riding up hills or transport-ing loads. -
After a ride, do not allow your unprotected hands or legs to come into contact with the housing of the drive unit. Under extreme conditions, such as continuously high torques at low travel speeds, or when riding up hills or carrying loads, the housing may reach a very high temperature.
The temperature that the drive unit housing may reach is influenced by the following factors:- Ambient temperature
- Ride profile (route/gradient)
- Ride duration
- Assistance modes
- User behaviour (personal effort)
- Total weight (rider, eBike, luggage)
- Motor cover on the drive unit
- Heat dissipation properties of the bicycle frame
- Type of drive unit and type of gear-shifting
-
Use only original Bosch batteries that the manufac-turer has approved for your eBike. Using other batter-ies can lead to injuries and pose a fire hazard. Bosch ac-cepts no liability or warranty claims if other batteries are used.
Keep the magnet away from implants and other medical devices, e.g. pacemakers or insulin pumps. The magnet generates a field that can impair the function of implants and medical devices. -
Keep the magnet away from magnetic data carriers and magnetically sensitive devices. The effect of the magnets may lead to irreversible data losses.
-
Observe all national regulations which set out the ap-proved use of eBikes.

Information on the noise emissions of the drive unit
Typically, the A-weighted noise emission level of the eBike system is < 70
dB(A). A key feature of the
Assembly
Checking the speed sensor (see figure A)
Speedsensor (slim)
The speed sensor (2) and its CenterLock magnet (4) or spoke magnet (3) are
mounted ex works in such a manner that the magnet, after a turn of the wheel,
moves past the speed sensor with a clearance of at least 2 mm, yet no more
than 15 mm.
If any structural changes are made, the correct distance between the magnet
and the sensor must be complied with (see figure A).
Note: Make sure you do not damage the sensor or the sensor holder when
fitting or removing the rear wheel.
When changing a wheel, make sure that the sensor cable is routed so that it is
not under tension and has no kinks.
The CenterLock magnet (4) can only be removed and rein-serted up to five
times.
Rim magnet
When installing a rim magnet, no sensor is required to detect a wheel turn.
The drive unit itself detects when the magnet is close to it and calculates
the speed and any other data re-quired from the frequency of the emergence of
the magnet field.
Since the drive unit is sensitive to magnetic fields, avoid other magnetic
fields in the vicinity of the drive unit (e.g. magnetic clipless pedals,
magnetic cadence sensors, etc.) in order to prevent disruption to the drive
unit.
Operation
A control unit is required for the starting operation of the eBike system.
Observe the starting operation for the eBike system and drive unit control in
the control unit operating in-structions.
Notes on cycling with the eBike system
When does the eBike drive work?
The eBike drive assists your cycling only when you are ped-alling. If you do
not pedal, the assistance will not work. The motor output always depends on
the pedalling force you ap-ply.
If you apply less force, you will receive less assistance than if you apply a
lot of force. This applies irrespective of the as-sistance level.
The eBike drive automatically switches off at speeds over 25 km/h. When the
speed falls below 25 km/h, the drive automatically becomes available again.
An exception applies to the push assistance function, in which the eBike can
be pushed at low speed without ped-alling. The pedals may rotate when the push
assistance is in use.
You can also use the eBike as a normal bicycle without as-sistance at any
time, either by switching off the eBike system or by setting the assistance
level to OFF. The same applies when the battery is drained.
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 to briefly stop
pedalling when changing gear. This will facilitate the gear change 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.
Gaining initial experience
We recommend that you gain initial experience with the eBike away from busy
roads.
Test the various assistance levels, beginning with the lowest level. As soon
as you feel confident, you can ride your eBike in traffic like any other
bicycle.
Test the range of your eBike in different conditions before planning longer
and more demanding trips.
Influences on range
The range is affected by a number of factors, such as:
- Assistance level
- Speed
- Gear shifting behaviour
- Tyre type and tyre pressure
- Age and condition of the battery
- Route profile (gradients) and conditions (road surface)
- Headwind and ambient temperature
- Weight of eBike, rider and luggage
For this reason, it is not possible to predict the range accur-ately before and during a trip. However, as a general rule:
- With the same assistance level on the eBike drive: The less energy you need to exert in order to reach a certain speed (e.g. by changing gears optimally), the less energy the eBike drive will consume and the higher the range per battery charge will be.
- The higher the selected assistance level under otherwise constant conditions, the smaller the range will be.
Taking care of your eBike
Please observe the operating and storage temperatures of the eBike components.
Protect the drive unit, on-board com-puter and battery against extreme
temperatures (e.g. from intense sunlight without adequate ventilation).
Extreme temperatures can cause the components (especially the battery) to
become damaged.
Have your eBike system checked by an expert at least once a year (including
mechanical parts, up-to-dateness of system software).
Maintenance and servicing
Maintenance and cleaning
When changing the bulbs, ensure that they are compatible with the Bosch eBike
system (ask your bicycle dealer) and are suitable for the specified voltage.
Bulbs must only be re-placed with bulbs of the same voltage.
Do not immerse any components, including the drive unit, in water or clean
them with pressurised water.
Have your eBike system checked by an expert at least once a year (including
mechanical parts, up-to-dateness of system software).
Please have your eBike serviced and repaired by an author-ised bicycle dealer.
