riding conditions. The on-board computer should
only be used in a stationary and safe start-up posi-
tion. Utilize the operating unit to change motor as-
sistance levels while riding.
Check your bicycle manual for maximum riding
u
weight of your bicycle. Overloading your bicycle
can result in component failure which can result in
death or serious injury. Typically maximum riding
weight is defined by the sum of the rider's weight
plus the weight of any luggage.

Notes on cycling with the eBike system
When does the eBike drive work?
The eBike drive assists your cycling only when you are
pedaling. If you do not pedal, the assistance will not
work. The motor output always depends on the pedal-
ing force you apply.
If you apply less force, you will receive less assistance
than if you apply a lot of force. This applies irrespec-
tive of the assistance level.
The eBike drive automatically switches off at speeds
over 28 mph. When the speed falls below 28 mph,
the drive automatically becomes available again.
An exception applies to the push assistance function,
in which the eBike can be pushed at low speed with-
out pedaling. The pedals may rotate when the push
assistance is in use.
You can also use the eBike as a normal bicycle with-
out assistance 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 instructions of your eBike on this point).
Irrespective of the type of gear-shifting, it is advisable
to briefly stop pedaling 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.
Test the range of your eBike in different conditions
before planning longer and more demanding trips.
Read and understand the influences on the oper-
u
ating range when planning your ride (see "Influ-
ences on range", page English – 10).

Influences on range
The range is affected by a number of factors, such as:
– Assistance level
– Speed
– Gear shifting behavior
– Tire type and tire pressure
– Age and condition of the battery
– Route profile (gradients) and conditions (road sur-
face)
– Headwind and ambient temperature
– Weight of eBike, rider and luggage
For this reason, it is not possible to predict the range
accurately 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 oth-
erwise constant conditions, the smaller the range
will be.
Note: Plan your routes so that you can always reach
your destination without motor assistance.
