The Motrice Pia was an early three-wheeled vehicle, introduced by Italian Enrico Bernardi, and sometimes credited as the first motorcycle. 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), the application of the engine to a child's tricycle in 1884, the application of this engine to a motorized tricycle (or low cart) in 1893, or the mounting of the motor behind a bicycle on a one-wheel trailer via chain drive creating a "motorcycle" in 1894.
Specifications in the box accompanying the article are from Museo Nicolis and refer to the 1884 tricycle.
