An electric bicycle is a bicycle that is powered by an electric motor. Electric bikes are also known as motorized bikes. These are fitted with a motor for pedaling, so that the rider doesn’t have to pedal. Electric bicycles generally contain a small electric motor or an internal combustion engine. However, internal combustion engines are being replaced by electric motors with the onset of lightweight, high-battery-storage motors. Electric bikes are very popular in some countries like China, where bicycles are still a chief mode of transportation.
The earliest motorbikes can be traced to the late 19th century. Motorcycles evolved from this development, which tried to power a regular bicycle with motor power. In fact, the moped is a direct descendent of the motor bicycle, and most mopeds still have pedals attached to them. Some mopeds also use pedals as a starting aid and for propulsion. The different kinds of electric bikes are: direct-drive, geared, chain drive, hub motors and friction drive. Another classification is the power-on-demand (motor is activated by a handle-bar mounted throttle) and the pedelec (motor is regulated by pedaling).
