"The Ducati Cucciolo was a 4-stroke clip-on engine for motorized bicycles conceived during and shortly after World War II by a Turin lawyer, Aldo Farinelli, and developed with a self-taught engineer, Aldo Leoni.During the war, Aldo Farinelli began working with the small Turinese firm Siata (Societ\u00E0 Italiana per Applicazioni Tecniche Auto-Aviatorie) with the idea of developing a small engine that could be mounted on a bicycle."@en . . .
