A minibike is a two wheeled, off-highway recreational vehicle popularized in the 1960s and 1970s, but available continuously from a wide variety of manufacturers since 1959. Traditionally, minibikes have a four-stroke, horizontal crankshaft engine, single- or two-speed centrifugal clutch transmissions with chain final-drive, 4" or 6" wheels and a low frame/seat height with elevated handlebars. Commercially available minibikes are usually equipped with engines commonly found elsewhere on utilitarian equipment.
