A Brief History of the Marque
Established in 1939 by Giovanni Olmo, the company built mopeds in Celle Ligure, Italy, using 48 and 49cc two-stroke single-cylinder engines of modern design. They also used Mosquito 38cc engines.
The firm is probably best known for bicycles, but they also produced goods for several other industries.
