If you're constantly on the move, different motel every night, then this is for you.
Built in France by Victor-Albert Bouffort in 1952, the Valmobile was initially marketed with sporty 125cc Briban Sabb engine, and said to have seated two comfortably. It included a trailer hitch. It is likely that a prototype was built with a 60cc Alter engine, and this was replaced with a Villiers 98cc unit.
Production versions were built by Martin Moulet and had a 50cc Martinet engine and weighed 75lbs. It was even available with a sidecar!
The tiny machine was marketed in Japan, America and Europe, In Japan, it was built under licence by Hirano. It was advertised in America as an accessory for motorhomes.
Bouffort was quite the inventor, and produced a rather beautiful three-wheeler in limited quantities. Production dates are unclear, but there are mentions of it as early as 1945 and as late as 1960.
