How many watts does an electric bike use?

How many watts does an electric bike use? How many watts an electric bike uses depends on how hard you ride, but generally, you consume between 10 to 20 watt-hours per mile. This means if you have a standard 500-watt-hour battery, you can expect to ride for roughly 25 to 50 miles depending on if you are using “Eco” mode or “Turbo” mode.
