Established in the 1930s [1] in Mandeure (Doubs), FMC was a subsidiary of the Cycles Peugeot group.
The company marketed machines built by Griffon, Christophe, Aiglon, Meteore and others, often rebadged as their own and with "France Motor Cycles" on the ID plate. The idea was to identify the machines as distinctly French to facilitate sales in English-speaking countries, where frequently anything French was considered favourably.
Trophée de France was another marque in the stable.
Griffon model designations were changed from first numeral 1 to 5, ie Griffon Type 176 = FMC Type 576
Meteore types were changed from 1 to 6, so Meteore type 176 becomes FMC type 676.
FMC Models
Tyre sizes on most models were 25x2.75F and 25x3R.
FMC engines were used by Aiglon, Trophee de France, Meteore and Griffon. It is possible that these engines were built by another company and rebranded by FMC.

Notes. 1. The firm may have been established in the 1920s, as one source says that FMC took over Aiglon in 1922.
