• 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
significantly increase the rolling resistance. The
distance you can travel also decreases if the brakes
are rubbing.
• Ascents
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 140 km
with the battery fully charged (18 Ah). You can expect to
cover a distance of roughly 85 km using different modes of
operation.

Riding your Pedelec efficiently

You can monitor and influence 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 of power assist with an 18 Ah battery
work out as follows:
• A new battery costs around 599 euro.
• You can cover 112 km on average with one battery
charge. You can charge the battery roughly 1,100
times.
• 1,100 charging cycles x 112 km = 123,200 km
• 599 euros: 123,200 km = 0.47 euro cents / km
• You use roughly 0.620 kWh to fully charge the bat-
tery. Assuming a unit price of 20 euro cents / kWh,
it costs you 12.4 euro cents to fully charge the bat-
tery and cover a journey length of 112 km.
• It costs you 0.20 euro cents / km to travel the mini-
mum distance of 60 km.
• It costs you 0.09 euro cents / km to travel the maxi-
mum distance of 140 km.
• This means the cost of consumption and the bat-
tery is a maximum of 0.67 euro cents / km.
As Derby Cycle is a German manufacturer, the sample cal-
culation is based on German energy prices. The operating
costs may therefore be different in locations where other
energy prices apply.
