Range
All electric bikes indicate a maximum mileage range that they can cover on a single battery charge. This is the furthest range in ideal conditions; however, this range can be impacted by a number of factors:
The combined weight of the rider and any luggage.
The assistance mode selected.
The cycling route (e.g. type of terrain and inclines).
Temperature and climate (e.g. cold weather will decrease the performance of the battery).
Tyre pressure.
Wind speed and direction.
