3.3 Factors affecting the remaining range
The neodrives motor is designed to be highly efficient and achieves an efficiency level of approx.
82% in the speed range from 20 to 25 km/h. Since it is a direct rotor (no gear as for example with
mid-engines), only small losses occur. The range that can be achieved by the rider is subject to
many influencing factors.
These are the main ones:
•
Topography:
Travelling on hilly terrain visibly affects the battery more than travelling on flat
terrain.
•
Weather:
On cold days the battery range can be 30-40% lower than on warm days. Head wind
also has an influence on power consumption.
•
Frequent acceleration/travelling at low speeds:
Large amounts of power are needed to
accelerate. Comparable with the high instantaneous fuel consumption occurring on a car when
starting off
.
•
System weight:
This factor is often underestimated. The weight of the rider and their belongings
contribute considerably to the overall mass of the bike (this is different in the case of a car).
•
Rider's effort:
The more effort the rider puts in, the higher the achievable range. It often helps to
switch down 1-2 gears to increase the input force or the cadence.
•
Tyre pressure:
If the tyre pressure is too low, the friction between the tyre and the ground surface
is increased, which can lead to a loss of several percentage points.
