The number of calories you burn on an electric bike depends on several factors, including your weight, the intensity of your ride, the terrain you're riding on, and how much assistance you're getting from the electric motor. In general, using an electric bike provides a lower level of physical exertion compared to riding a regular bike, as the motor provides assistance for pedaling.

Studies have shown that riding an electric bike can burn between 300 to 500 calories per hour, depending on the factors mentioned above. This is lower than the calorie burn for riding a traditional bike, which can range from 400 to 1000 calories per hour depending on the intensity of the ride.

However, it's important to remember that using an electric bike can still provide health benefits, especially if it encourages you to exercise more frequently or for longer periods than you would on a regular bike. Additionally, using an electric bike can make it easier to tackle challenging terrain, steep hills, or longer distances, which can further increase the number of calories burned.
