Electric bicycle, also known as e-bike or mountain bike is a bike, booster with built-in electric motor that can be used for propulsion. There is a great variety of different types of e-bikes are available worldwide, from e-bikes that have only a small motor to help power the rider pedals (i.e. pedelecs) for somewhat more powerful electric bicycles, which are closer to the moped-style: all functionality, however, retains the ability to be on the brakes rider and therefore not electric motorcycles. E-bicycles use rechargeable batteries and light varieties can travel up to 25 to 32 km/h (from 16 to 20 mph), depending on the laws of the country in which they are sold, While more powerful options can often more than 45 km/h (28 mph). In some markets, such as Germany, they are gaining in popularity and taking some market share from the traditional bicycle, while in other countries, such as China, they replace fossil fuel powered mopeds and small motorcycles.

Depending on local laws, many e-bikes (for example, pedelecs), have the legal status as bicycles, not motorcycles or mopeds, so they are not subject to the more stringent laws against their certification and operation, in contrast to the more powerful two-wheeled vehicles, which are often classified as electric motorcycle. E-bikes can be identified separately and treated as a specific type of vehicle in many areas of jurisdiction.

E-bike motor-powered bicycle, motorized versions that have been around since the late 19 century.
