What determines the range of an e-bike?

The most basic calculation for range involves the battery's capacity. For example, a 36 V 10.4 Ah battery holds 374.4 Wh. If the bike uses 5 Wh per kilometer at a steady 25 km/h, the expected range would be around 75 km. Yet, ideal scenarios are rare. Factors such as steep hills, frequent stops, and headwinds can significantly drain the battery. Imagine riding on a perfectly flat road; in this situation, you might reach the predicted range. However, climbing a steep incline reduces it, while descending may extend it.

The level of pedal assistance you choose also impacts range. JOBOBIKE e-bikes feature settings ranging from low to high. Maximum assistance uses more power and shortens battery life. If you ride on mid or low settings, especially on flat terrain, you can stretch the range. An e-bike operates like a hybrid between motor power and your pedaling effort. The less you pedal, the more the motor compensates, increasing energy use. Consistent pedaling helps extend the battery life, while reliance on the motor, especially on high settings, will shorten it.

Weight is another significant factor. It’s not just the bike’s weight but also the rider and any load being carried. Range estimates usually consider a bike weight of 20 kg and a rider weight of 70-80 kg. Heavier riders or those carrying extra items will find that the battery depletes faster. Urban commuters should also be mindful of frequent stops at traffic lights, as starting from a standstill consumes more energy than maintaining speed. An uninterrupted path allows you to get closer to the bike’s maximum potential range.

Adjusting expectations based on real-life scenarios

It’s important to set realistic expectations for your e-bike’s range. For example, we once had a customer who was not reaching the advertised distance per charge, even after replacing the battery. After investigating, we discovered the rider was 1.95 meters tall, weighed 122 kg, and always used the highest level of pedal assistance. This meant the battery couldn’t achieve the expected 70-80 km range. The case highlights how weight and riding style can affect distance. By understanding these factors, you can better plan your rides and make the most of your e-bike.

At JOBOBIKE, we provide guidelines that consider typical routes, terrain, and riding habits to help set clear and realistic range expectations. We encourage our riders to think about their usual habits and needs when selecting a model and battery. Finding the right balance between pedal effort and motor assistance can make all the difference.
