A Brief History of the Marque
A bicycle manufacturer since 1905, Giuseppe Gaia began building motorcycles in 1922. The first model was equipped with the German Alba (1) engine, an inclined single cylinder side-valve 192cc with magneto ignition. It has girder forks, a separate two-speed gearbox, primary and secondary transmission by chain, and on the right there is the chain for the pedals.
The firm also used two-stroke and four-stroke engines from DKW, Casoli, Rubinelli, Train, Paque, GD, MM, and Siat. After 1927, Ladetto & Blatto supplied most of their engines, and Gaia in turn supplied them with numerous different frames.
The company closed in 1932.
1. Tragatsch says the first machines had Rubinelli bicycle engines, and that the next two were motorcycles fitted with Alba engines of 123 and 173cc.
