6.2 Distance
The distance you can travel using the power assist with
the battery lly charged depends on several factors:
• Ambient temperature
If it is colder, you will travel a shorter distance
with the same battery charge.
To maximise the distance you can travel, keep the
battery in a heated room so that it is at room tem-
perature when you t it on your Pedelec.
As the battery discharges when the motor is in use,
it generates enough heat to not lose too much of its
power at low ambient temperatures.
• Selected assist level
If you want to cover a large distance with power
assist, select the smaller gears, i.e. the ones that
are easier to pedal. Also select a low assist level
(ECO).
• Handling
If you are riding in gears that are harder to pedal
and select a high assist level, the motor will pro-
duce plenty of power to help you along. However,
just as with driving a car at high speed, this leads
to higher consumption. You will therefore have
to recharge the battery sooner. You can conserve
energy by keeping the load on the pedals even
throughout the entire crank revolution.
• Technical condition of your Pedelec
Make sure the tyre pressure is correct. If you ride
your bike with too little air in the tyres, this can
signicantly increase the rolling resistance. This
applies to smooth surfaces in particular, e. g. tar-
mac. If the ground is uneven, as on a country path
or gravel track, rather low tyre pressure can lead to
less rolling resistance. This also increases the risk
of a puncture. Please consult your specialist cycle
shop about this.
The distance you can travel also decreases if the
brakes are rubbing.
• Battery capacity
The current battery capacity
➠ Chapter 7.4.2 "Checking the battery capacity"
• Topography
You pedal harder when riding uphill. This is de-
tected by the power sensor which then allows the
motor to work harder.
Under ideal conditions, you can cover roughly 100km
with the battery lly charged.

6.3 Riding your Pedelec eciently
You can monitor and inuence the cost of your journeys
with the Pedelec yourself. You can reduce your consump-
tion and therefore costs by following the tips for increas-
ing the travel distance.
The operating costs for battery-operated power assist are
calculated as follows:
• A new battery costs roughly 599euros.
• You can cover 80km on average with one battery
charge.
• You can charge the battery roughly 1,100 times.
• 1,100 charging cycles x 80km = 88,000km
• 599euros: 88,000km = 0.68euro cents / km
• You use roughly 0.565kWh to lly charge the bat-
tery. Assuming a unit price of 20euro cents / kWh,
it costs you 11.3euro cents to lly charge the bat-
tery.
• It costs you 0.14 euro cents / km to cover the aver-
age range of 80km.
• This means that the maximum cost of consumption
and the battery is 0.82euro cents / km.
The sample calculation has been carried out based on Ger-
man energy prices. The operating costs may therefore be
dierent in locations where other energy prices apply.
