An electric, three-wheeled motor scooter is described which can derive its motive energy either from a solar-electric array on the vehicle or an independent source of electric power. The vehicle has a unique suspension which permits limited lateral rotation of the forward portion of the vehicle relative to the rear portion, and thereby, facilitates handling and ease of use. Speed and acceleration are controlled through a modulated pulse width controller which supplies pulses of electrical energy to the DC motor in response to throttle commands.

[ What is claimed is:] [1.] An electrically powered, three wheeled vehicle comprising:a single, steerable front wheel mounted on a front axle;an elongated steering column having a lower end which engages with said front axle to enable turning thereof; and,an elongated chassis, having a fore and aft longitudinal axis, said chassis extending between said front and rear axle and comprising a forward section which pivotally engages with said steering column, a middle section to accommodate one or more persons, and a rear section joined to a bracket which engages transversely with said rear axle, said bracket having mounted thereon an electric motor to rotatably drive at least one of said rear wheels, said bracket further including two spaced lateral members which transversely engage pivotally with said rear section of said chassis to permit limited lateral rotational movement of said bracket relative to said longitudinal axis of said chassis, a rotational force from said motor to said driven rear wheel, a source of stored electrical energy to power said motor, and a controller disposed between said source and said motor to control delivery of said power to said motor.
