Alcyon 250 cc (1926). 

The Alcyon was a French bicycle, automobile and motorcycle manufacturer between 1903 and 1954.

Alcyon originated from about 1890 when Edmond Gentil started the manufacture of bicycles in Neuilly, Seine. In 1902, this was complemented by motorcycle production and in 1906, the first cars were shown at the fair “Mondial de l’Automobile” in Paris, France. Also in 1906 it founded the professional Alcyon cycling team which was active until 1955, including winning the Tour de France 6 times.

In 1912 Alcyon competed at the Isle of Man TT races with a 348cc single-cylinder engine featuring two inlet valves and two exhaust valves. Both bikes failed to finish the Junior TT race.

Alcyon had local success in France during the 1920s, with riders such as Marc Jolly, Marcel Mourrier, Jean Durand and Lucien Lemasson winning races. During this time too, this bicycle brand got its nickname “l’intrépide Alcyon”.
