"Electric bike" redirects here. For electrically powered motorcycles, see Electric motorcycles and scooters.
Electric bicycles are very common in China, with an estimated fleet of 120 million e-bikes by early 2010.
An electric bicycle, also known as an e-bike, is a bicycle with an electric motor used to power the vehicle. Electric bicycles use rechargeable batteries and can travel up to 15 to 20 mph (24 to 32 km/h), depending on the laws of the country in which they are sold. In some markets they are rapidly replacing traditional bikes and motorcycles.
In many parts of the world, electric bicycles are classified as bicycles rather than motor vehicles, so they are not subject to the more stringent laws regarding certification and operation of motor vehicles. Electric bicycles are one type of motorized bicycle. However, electric bicycles are defined separately and treated as a specific vehicle type in many areas of legal jurisdiction.
