A Brief History of the Marque
Established by the frères Picard.
1926 to 1956
Sully sur Loire.
Les Ateliers Helyett began producing bicycles in 1926 and entered the motorcycle trade in the 1930s, at which time they had around 50 workers. They built lightweight two-strokes, and touring machines powered by Chaise OHV singles along with 750cc & 998cc JAP twins.
There was also an interesting shaft-drive V-twin of similar configuration to the post-war Moto-Guzzi twins. The MH136 was powered by a transverse JAP sidevalve engine driving via cardan shaft to the rear wheel.
Subsequent to World War II Helyett built mopeds and lightweights up to 175cc.
The firm continued to build bicycles until 1962, their bikes being very successful in racing, winning Le Tour de France in 1957, 61 and 62.
Helyet was bought by Griffon in 1962.
