Libbey, human and motor inputs are mechanically coupled either in the bottom bracket, the rear wheel, or the front wheel, whereas in a (mechanical) series hybrid cycle, the human and motor inputs are coupled through differential gearing. In a parallel hybrid motorized bicycle, such as the aforementioned 1897 invention by Hosea W. The terms 'electric motorbike' or 'e-motorbike' refer to more powerful models that attain up to 80 km/h (50 mph). Performance varies however, in general there is an increase in range and speed with the latter battery types.īy 2001 the terms e-bike, power bike, ' pedelec', pedal-assisted, and power-assisted bicycle were commonly used to refer to e-bikes. Some of the less expensive e-bikes used bulky lead acid batteries, whereas newer models generally used NiMH, NiCd, and/or Li-ion batteries, which offered lighter, denser capacity batteries. By contrast, according to Gartner, in 1995 regular bicycle production decreased from its peak 107 million units.Īmerican car icon, Lee Iacocca founded EV Global motors in 1997, a company that produced an electric bicycle model named E-bike SX and it was one of the early efforts to popularize e-bikes in the United States. Production grew from 1993 to 2004 by an estimated 35%. Yamaha, a Japanese automotive giant built one of the early prototypes of e-bike back in 1989 and invented the pedal assist system in 1993. Despite the Zike, in 1992 hardly any commercial e-bikes were available. The bicycle included NiCd batteries that were built into a frame member and included an 850 g permanent-magnet motor. In 1992 Vector Services Limited offered and sold an e-bike dubbed Zike. For example, Takada Yutky of Japan filed a patent in 1997 for such a device. Torque sensors and power controls were developed in the late 1990s. Wood's device used 4 fractional horsepower motors connected through a series of gears. Schnepf's invention was later re-examined and expanded in 1969 by G.A. Patent 627,066 by John Schnepf depicted a rear-wheel friction 'roller-wheel' style drive electric bicycle. This model was later re-invented and imitated in the late 1990s by Giant Lafree e-bikes.īy 1898 a rear-wheel drive electric bicycle, which used a driving belt along the outside edge of the wheel, was patented by Mathew J. The motor was designed within the hub of the crankset axle. Patent 596,272) that was propelled by a 'double electric motor'. Libbey of Boston invented an electric bicycle ( U.S. There were no gears and the motor could draw up to 100 amperes (A) from a 10-volt battery. Patent 552,271 for a battery-powered bicycle with '6-pole brush-and-commutator direct current (DC) hub motor mounted in the rear wheel'. For example, on 31 December 1895, Ogden Bolton Jr. In the 1890s, electric bicycles were documented within various U.S.

In UK legislation the vehicles are called EAPC or Electrically Assisted Pedal Cycle, in EU legislation EPAC or Electrically Power Assisted Cycle. E-bikes can also be defined separately and treated under distinct electric bicycle laws.

This exempts them from the more stringent laws regarding the certification and operation of more powerful two-wheelers which are often classed as electric motorcycles. ĭepending on local laws, many e-bikes (e.g., pedelecs) are legally classified as bicycles rather than mopeds or motorcycles.

High-powered varieties can often travel more than 45 km/h (28 mph).Į-bike use is growing in some markets, as they are seen as an eco-friendly and healthy alternative to cars, fossil fuel-powered mopeds and small motorcycles, and a less intense physically intense alternative to conventional bicycles. E-bikes use rechargeable batteries and typically are motor-powered up to 25 to 32 km/h (16 to 20 mph). Both retain the ability to be pedaled by the rider and are therefore not electric motorcycles. pedelecs) and bikes that add a throttle, integrating moped-style functionality. 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. An electric bicycle ( e-bike, eBike, etc.) is a motorized bicycle with an integrated electric motor used to assist propulsion.
