Electric trike
An electric trike is a three-wheeled vehicle powered by an electric motor. It may have a feet forward configuration.
Overview
While the normal legal definition of motorcycle is a two-wheeled vehicle, in the USA a motorcycle may also be three wheeled. This classification does not depend on whether the operator is fully enclosed by a "cage" or exposed to the elements. Several automotive startup companies made their initial designs three wheeled vehicles, because the motorcycle classification does not require the same costly battery of crash safety testing as a four wheeled vehicle. They may find a sales advantage because insurance and licensing requirements are simplified or non-existent if the local laws classify these types of vehicles as a bicycles.
For design purposes, three wheeled vehicles are divided into 2 categories:
Some three wheeled motorcycles enclose the rider in a "cabin" or cockpit. These include the Twike, Myers Motors NmG, , ...
Some three wheeled motorcycles have independent suspension allowing the vehicle to tilt or lean, such as the Carver one.
