The ("J. Moyne or G. Moynes") was a French freewheel manufacturer based in Saint-Étienne.

Active mainly between the 1930s and 1950s, it produced 3- to 5-speed models with French threading (34.7 x 1 mm).

Its freewheels were fitted to many French racing and touring bicycles after the war.

Some models were robust and well designed, while others were more fragile, depending on the series.

Production ceased with the decline of the Saint-Étienne bicycle industry in the 1960s and 1970s.
