The Motrice Pia was an early three-wheeled vehicle, introduced by Italian Enrico Bernardi, and sometimes credited as the first motorcycle.[1] The exact year of introduction depends on which one of the following milestones one considers: the demonstration of a gasoline engine in 1882–1884 (first used to power a sewing machine),[2][3] the application of the engine to a child's tricycle in 1884,[4] the application of this engine to a motorized tricycle (or low cart) in 1893,[2][5] or the mounting of the motor behind a bicycle on a one-wheel trailer via chain drive creating a "motorcycle" in 1894.[2]
