In 1946, the Cucciolo appeared: the small auxiliary motor for bicycles destined to become the most famous in the world. First sold in an assembly box to be attached to the bicycle, it soon acquired a frame of its own, which was constructed by Caproni in Trento (another famous brand in the aeronautical field) and based on a Capellino patent. In a short time, the Cucciolo became a real miniature motorcycle. Thank to the Cucciolo’s success, and that of its descendants, Ducati became an affirmed trademark in the mechanical sector.
