Electric motorcycles

Electric motorcycles and scooters are plug-in electric vehicles with two or three wheels powered by electricity. The electricity is stored on board in a rechargeable battery, which drives one or more electric motors. Electric scooters (as distinct from motorcycles) have a step-through frame.

Electric motorcycles: manufacturers include Brammo, Zero Motorcycles, Lightning Motorcycle, Energica Motor Company, Quantya, Electric Motorsport, Hollywood Electrics, Yo and Lito. Yamaha plans to enter the market shortly with at least two models. Spanish company Bultaco intends to enter the electric motorcycle market in 2015. Heavyweight Harley Davidson introduced a new prototype electric motorcycle in June 2014.

Electric scooters: the primary commercial production supplier for worldwide markets, is Z Electric Vehicle. The BMW C Evolution electric scooter was released in Germany in May 2014. Honda participated in European lease demonstration and driving tests for its electric scooter in 2012 but has not yet announced its availability for sale. Terra Motors, a Japanese electric vehicle maker, will begin selling electric scooters in India by 2015. Gogoro announced a swappable battery electric scooter at CES 2015.

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 be have a range of 75 miles (121 km) to 100 miles (160 km) per charge. The motorcycle had a three-speed controller, with speeds of 4 miles (6.4 km), 15 miles (24 km) and 35 miles (56 km) per hour.

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 the an electric motorcycle company called Socovel (Société pour l’étude et la Construction de Vehicules Electriques or Company for research and manufacture of electric vehicles) 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 (current-day ParCar Corp.).
