What is an e-bike/electric bike? | IMREN Sports
An electric bicycle (e-bike, eBike, etc.) is a bicycle with an integrated electric engine used to assist propulsion. Many kinds of e-bikes are available worldwide, but they 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.
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). In some markets, such as Germany as of 2013, they are gaining in popularity and taking some market share away from conventional bicycles, while in others, such as China as of 2010, they are replacing fossil fuel-powered mopeds and small cycles.
Depending on local laws, many e-bikes (e.g., pedelecs) are legally classified as bicycles rather than mopeds or cycles. This exempts them from the more stringent laws regarding the certification and operation of more powerful two-wheelers which are often classed as electric cycles. E-bikes can also be defined separately and treated under distinct electric bicycle laws.
In UK legislation the vehicles are called EAPC or Electrically Assisted Pedal Cycle, in EU legislation EPAC or Electrically Power Assisted Cycle.
E-bikes are the electric engine-powered versions of engined bicycles, which have been in use since the late 19th century. Some bicycle-sharing systems use them.
