III User Manual Pedelec with centre motor 17
• 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
signicantly 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 140km
with the battery lly charged (18 Ah). You can expect to
cover a distance of roughly 85km using dierent modes of
operation.

5.3 Riding your Pedelec eciently
You can monitor and inuence 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 599euros.
• You can cover 112 km on average with one battery
charge.
• You can charge the battery roughly 1,100 times.
• 1100 charging cycles x 112km = 123,200km
• 599euros: 123,200km = 0.47euro cents / km
• You use roughly 0.620kWh to lly charge the bat-
tery. Assuming a unit price of
20euro cents / kWh,
it costs you 12.4euro cents to lly charge the bat-
tery and cover a journey length of 112 km.
• It costs you 0.20euro cents / km to travel the mini-
mum distance of 60 km.
• It costs you 0.09euro cents / km to travel the maxi-
mum distance of 140km.
• This means the cost of consumption and the bat-
tery is a maximum of
0.67euro 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 dierent in locations where other
energy prices apply.
