E-Bike 101: Estimating Your E-Bike's Battery Range in Kilometers

2 Minute Read
TL;DR: Range (km) = Ah x Volts / 12.43 (Wh/km)

When it comes to e-bikes, one of the most important factors to consider is the battery range. Knowing how far your e-bike can go on a single charge can help you plan your rides and ensure that you don't get stranded without power. In this article, we will explain how to calculate e-bike battery range in kilometers, given the volts and amp hours of your battery.

First, it's important to understand the difference between volts and amp hours. Volts (V) measure the electrical potential of the battery, while amp hours (Ah) measure the amount of energy stored in the battery. To calculate the range of your e-bike battery, you will need to know both the volts and amp hours of your battery.

Once you have this information, you can use the following formula to calculate your e-bike battery range:

Range (km) = Ah x Volts / 12.43 (Wh/km)*

Ex:
48V 20Ah Battery
Range (km) = 20Ah x 48V / 12.43 Wh/km
Range (km) = 77 km


*12.43 is Wh/km is an estimation only taken from our daily rides in Quezon City,PH majority are on flat roads. (65kg average weight)

It's important to note that this calculation is an approximation and that the actual range of your e-bike battery will depend on a number of factors, such as the weight of the rider, the terrain, and the weather conditions. This formula is also based on the assumption that the bike is used under ideal condition and the efficiency of the motor, controller and other components.
