08 Drive Unit
8.3 Operation
Operation
A control unit from the smart system generation is required for the
starting operation of the eBike. Please observe the operating instructions
of the control unit and, if necessary, additional components from the
smart system generation.
Notes on Cycling with Your eBike
When does the drive work? The drive assists your cycling only when you
are pedalling. If you do not pedal, the assistance will not work. The drive
power always depends on the pedalling force and cadence you apply.
With low force or cadence, the support will be less than with high force
or cadence. This applies irrespective of the assistance level.
The drive automatically switches off at speeds over 25 km/h. When the
speed falls below 25 km/h (15.5mph), the drive automatically becomes
available again. An exception applies to the walk assistance function,
in which the eBike can be pushed at low speed without pedalling. The
pedals may rotate when the walk assistance is in use.
You can also use the eBike as a normal bicycle without assistance at any
time, either by switching off the eBike or by setting the assistance level
to OFF. The same applies when the eBike battery is drained.
Interaction Between the Drive Unit and Gear-shifting
The gear shifting should be used with an eBike 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 briey
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.
Inuences 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 eBike battery
– Route prole (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 accurately before
and during a trip. However, as a general rule:
– With the same assistance level on the 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 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 computer and eBike battery against extreme temperatures (e.g.
from intense sunlight without adequate ventilation). The components
(especially the eBike battery) can become damaged through extreme
temperatures. All components tted to the drive unit and all other
components of the drive (e.g. chainring, chainring receptacle, pedals,
cranks) must only be replaced with identical components or components
that have been specically approved by the manufacturer for your eBike.
This will protect the drive unit from overloading and becoming damaged.
When replacing the crank, make sure to use exactly the same crank as
a spare part, so that damage to the drive unit is ruled out. If you have
any questions and for further information, contact an authorised bike
retailer. Do not immerse any components, including the drive unit, in water
or clean them with pressurised water. Have your eBike checked by an
expert at least once a year (including mechanical parts, up to date system
software). Please have your eBike serviced and repaired
by an authorised bicycle retailer.
INFO: The A-weighted emission sound pressure level at the
driver ears is less than 70 dB(A).
