An electric bicycle also known as an e-bike or ebike is a bicycle with an integrated electric motor which can be used to assist propulsion. Many kinds of e-bikes are available worldwide, but generally fall into two broad categories. Bikes that assist the rider’s pedal-power (i.e. pedelecs) and bikes that add a throttle, integrating moped-style functionality. Both retain the ability to be pedaled by the rider and are therefore not electric motorcycles.

E-bikes use rechargeable batteries and typically travel up to 25 to 32 km/h (16 to 20 mph). High-powered varieties can often travel more than 45 km/h (28 mph).

E-bikes function like hybrid electric vehicles since the electric motor combines battery propulsion with another source of electricity but this time by pedal power instead of internal combustion engine power so in some cases the terms used would be hybrid electric bicycle or hybrid pedal-electric bicycle.
