In 1910 Alcyon buys the factory from Thomann. They kept the brand and the dealers but started to build the same motorcycles as Alcyon.

In 1934, a new model, the Légère, came on the market. This is a 175cc 2 stroke with a Zurcher engine with 2 gears. These engines were built at Alcyon, Armor, Labor, La francaise, Lapize, Olympique and Thomann.

This is an unfinished restoration, engine is rebuilt, frame with fork and fenders are already painted. Wheels and tank still need to be done.
