III User Manual Pedelec with centre motor 19
• 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. 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 lly charged (18 Ah). You can expect to
cover a distance of roughly 85km using dierent modes of
operation.

5.3 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 power assist with an 18 Ah battery
are calculated as follows:
• A new battery costs roughly 599euros.
• You can cover 112 km on average with one battery
charge.
• You can charge the battery roughly 1,100 times.
• 1100 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 lly charge the bat-
tery. Assuming a unit price of
20euro cents / kWh,
it costs you 12.4euro cents to lly 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 dierent in locations where other
energy prices apply.
