The exact range of an E-bike depends on many factors. Think of air resistance, rolling resistance, the extent to which you ride along, your own weight and the mode you use while cycling.
Experience shows that the range of a Santos PX with a 500Wh battery is between 25 and 100km.
Tip: Would you like to extend your range? You can easily carry an extra battery in the Hold-it-All or in a pannier.
The capacity of a battery cell is practically the same for every E-bike. How much range you get from a certain amount of battery cells depends on:
1. How many 'cells' your battery us made of (more cells, more capacity).
2. The circumstances in which you ride your bike.
3. Support mode (and the firmware that goes with it)
4. Efficiency of the system.
