All about the range of electric bikes
Electric bikes are becoming an increasingly popular means of getting around. With your electric bike, you can travel up to 20 mph, with little effort. This means you can get to work avoiding traffic jams and without feeling tired. It's also a great way to go for a ride and, depending on the model, for much sportier outings, in the forest or even in the mountains, on sometimes very steep terrain.
But if you're going to race through town or the forest, your bike battery needs to have sufficient average autonomy. In this article, we explain everything you need to know about the operation and maintenance of an electric bike battery.
How Many Miles Can You Ride an Electric Bike?
There are multiple electric bike models, with theoretical ranges generally varying from 30 to 75 miles. For example, the Specialized electric bike offers an approximate range of 75 miles.
On average, city electric bikes allow you to travel about 40 miles before needing to be recharged. But, the distance you can cover on your electric bike depends on multiple factors.
What happens when your electric bike runs out of battery? Don't worry, you won't be left stranded! You'll still be able to pedal as you would on a conventional bike, though it will be more laborious due to the extra weight of the electric components. That's why it's important to choose your electric bike carefully and determine the range you'll need for daily use. Once you've reached your destination, all you have to do is plug the battery into an outlet.
For a full charge, this operation will take between 4 and 7 hours, depending on the model.
The Role of the Battery in Your Electric Bike's Range
Battery Capacity: What Are All These Figures?
The battery is, in a way, the tank of your electric bike. Its capacity will partly determine the distance you can cover. Battery capacity is expressed in Watt-hours (Wh). The higher this figure, the greater the energy carried by the battery, and the longer the range. Some manufacturers use Ampere-hours (Ah) and voltage to express capacity. Since voltage is almost always 36V, it's the amperage that you need to rely on. It varies between 5Ah and 18Ah.
To calculate the capacity of your electric bike battery in Wh, simply multiply the voltage in Volts (V) by the capacity in Ampere-hours (Ah). For example, a 36V, 14Ah battery will have a capacity of 36V x 14Ah = 504 Wh.
Translating Battery Capacity into Miles
Here are a few figures to give you an idea of the real range offered by an electric bike battery according to its capacity in Watts:
- 260 Wh = about 25 miles
- 375 Wh = about 40 miles
- 520 Wh = about 50 miles
Bear in mind, however, that the range suggested by manufacturers is for guidance only: it is calculated under favorable conditions and is a theoretical range.
