Electric motorcycles and scooters
Electric motorcycles and scooters are plug-in electric vehicles with two or three wheels. Power is supplied by a rechargeable battery that drives one or more electric motors. Electric scooters are distinguished from motorcycles by having a step-through frame, instead of being straddled. Electric bicycles are similar vehicles, distinguished by retaining the ability to be propelled by the rider pedaling in addition to battery propulsion.
Electric scooters with the rider standing are known as escooters.
History
1895 to 1950
The early history of electric motorcycles is somewhat unclear. On 19 September 1895, a patent application for an "electrical bicycle" was filed by Ogden Bolton Jr. of Canton Ohio. On 8 November of the same year, another patent application for an "electric bicycle" was filed by Hosea W. Libbey of Boston.At the Stanley Cycle Show in 1896 in London, England, bicycle manufacturer Humber exhibited an electric tandem bicycle. Powered by a bank of storage batteries, the motor was placed in front of the rear wheel. Speed control was by a resistance placed across the handlebars. This electric bicycle was mainly intended for racetrack use.
The October 1911 issue of Popular Mechanics mentioned the introduction of an electric motorcycle. It claimed to have a range of to per charge. The motorcycle had a three-speed controller, with speeds of.
In 1919, Ransomes, Sims & Jefferies made a prototype electric motorcycle in which the batteries were fitted under the seat of the sidecar. Even though the vehicle was registered for road use, it never went past the trial stage.
In 1936, the Limelette brothers founded an electric motorcycle company called Socovel in Brussels. They continued production during the German occupation with their permission. Due to fuel rationing, they found some degree of success. But after the war, they switched to conventional models. The electric models remained available until 1948.
During the World War II, compelled by fuel rationing in the United States, Merle Williams of Long Beach, California, invented a two-wheeled electric motorcycle that towed a single-wheeled trailer. Due to the popularity of the vehicle, Williams started making more such vehicles in his garage. In 1946, it led to the formation of the Marketeer Company.
1950 to 1980
In 1967, Karl Kordesch, working for Union Carbide, made a fuel cell/Nickel–cadmium battery hybrid electric motorcycle. It was later replaced with a hydrazine fuel cell, giving it a range of and a top speed of.In the same year, a prototype electric motorcycle called the Papoose, was built by the Indian Motorcycle Company under the direction of Floyd Clymer.
In 1974, Auranthic Corp., a small manufacturer in California, produced a small motorcycle called the Charger. It had a top speed and an range on a full charge.
In the early 1970s, Mike Corbin built a street-legal commuter electric motorcycle called the Corbin Electric. Later in 1974, Corbin, riding a motorcycle called the Quick Silver, set the electric motorcycle speed world record at. The motorcycle used a 24 volt electric starter motor from a Douglas A-4B fighter plane. In 1975, Corbin built a battery-powered prototype street motorcycle called the City Bike. This motorcycle used a battery manufactured by Yardney Electric.
In June 1975, the first Annual Alternative Vehicle Regatta was held at Mt. Washington, New Hampshire. The event was created and promoted by Charles McArthur, an environmentalist. On June 17, Corbin's motorcycle completed the uphill course in 26 minutes.

Types
A two- wheeled powered vehicle if ridden with rider astride is termed a motorcycle; if it has a step-through frame with rider seated with feet on a floor panel it is a motor scooter. A smaller vehicle, typically just a deck to stand on with two wheels and a handlebar on a vertical stem is also termed a scooter; such scooters if unpowered are termed kick scooters, and e-scooters if battery powered. E-scooters are made available for hire by several companies in a scooter-sharing system.Power source
Since electric motorcycles and scooters have relatively small frames, they typically have short ranges, restricted by the volume available for energy storage.Most electric motorcycles and scooters are powered by rechargeable lithium ion batteries, though some early models used nickel–metal hydride batteries.
Alternative types of batteries are available. Z Electric Vehicle pioneered use of a battery with lead electrodes and an electrolyte of a liquid low sodium silicate compound, a variation on the classic lead–acid battery invented in 1859 and still used for electrical power in internal-combustion-engine automobiles, that compares favorably with lithium batteries in size, weight, and energy capacity, at considerably less cost.
EGen says its lithium-iron phosphate batteries are up to two-thirds lighter than lead-acid batteries and offer the best battery performance for electric vehicles.
In 2017, the first vehicle in the US to use the new Lithium Titanium Oxide battery non-flammable battery technology was a scooter called The Expresso. This technology allows a battery to charge in less than 10 minutes, and is capable of 25,000 charges, the equivalent of 70 years of daily charges. The technology, created by Altairnano, is used in China, where over 10,000 urban buses run on these batteries.
