The first machines were fitted with 78cc Le Poulain engines, and from 1930 they built motorcycles and triporteurs powered mostly by Villiers, with some of the pre-war models sporting JLO two-strokes.
After the war the factory, which had been bombed, swung into production quite quickly due in part to the stash of engines hidden from the ravages of fascism. Beginning once more with clip-on engines, the range soon encompassed Villiers models from 98c to 200cc, and in the early 1950s Gasquy 50cc engines (Le Poulain built in Belgium under licence) along with JLO and Sachs-powered mopeds. They also built a model using the excellent if short-lived JLO 250cc twin.
During this time they continued with a range of triporteurs using mostly Villiers singles. One source says that they imported the Oscar scooter from Britain in 1953, but as only two prototypes were built this does not seem likely.
