Alcyon Motorcycles

A Brief History of the Marque

40 - 52 rue de la Garenne

Originally a bicycle manufacturer, the firm was founded by Edmond Gentil at Neuilly sur Seine in 1902. The following year he created the Deauville brand, the address given at on advertising of 1906 being 37-39 Rue Garnier, Neuilly-sur-Seine.

Alcyon produced a considerable variety of models from 98cc two-strokes to large capacity vertical and V twins, and produced a shaft-drive version during the 1930's.

The Swiss firm Zedel had opened a factory in France, and when the parent company folded the French concern was absorbed by Alcyon with the result that most Alcyon motorcycles were built with Zedel (aka ZL or Zurcher) engines.

The firm absorbed several other French manufacturers including Armor, Labor, Thomann and Olympique. Postwar they produced smaller capacity two and four stroke machines using engines from AMC, VAP and Zürcher. Alcyon was absorbed by Peugeot in 1954. Some sources indicate the marque disappeared 1957, others as late as 1968. Another French marque, Austral, is related.

Alcyon machines were built under licence in Italy from 1926 to 1928, producing motorcycles of 98cc and 175cc. See Alcyon Italy

The machine appears very similar to a 1917 model in the gallery restored by the Bretti Brothers of Turin. We have no data on Alcyon serial numbers at present. Should you find a source please share so that it may be added here: Serial Numbers

For your info: Alcyon also made mopeds (50cc) - see picture (i'm not sure if the saddle is original)
Bram Desmet

    It is very similar to a 1936 velomoteur pictured in the Alcyon 1930s gallery, but the forks differ so it is possibly a slightly earlier model.

Alcyon poss 1920s

I know of a Alcyon that is fitted with what appears to be a JAP engine embossed 'made in France'. Were any JAP engines manufactured under licence in France or is it more likely to have been manufactured in England but embossed in this way to be fitted to an Alcyon machine? I have been unable to find any evidence that Alcyon ever fitted a JAP. I'd be grateful for any guidance you can give. Many thanks.

    Can find no direct evidence that JAP engines were built in France, but there are references to them being assembled there so possibly castings were made. Alcyon used JAP engines in 1925, apparently, but only for that year. Can you supply images?

Dating certificate-letter
I'm considering purchasing the motorcycle, but to register it in the UK with the DVLA I will need a dating letter. When I have the full details, can you provide the letter and what is the cost.
If yes, what info would you require.
If no, where can I obtain the certificate/letter.
Thank You

Dec 5th 2015 Cycles Motocyclettes Automobiles Alcyon : Championne de France du Tour

Treize Tours de France à son actif, dix-huit Paris-Roubaix, une série stupéfiante et inégalée de victoires dans le monde cycliste et motocyliste, dont le premier titre de champion du monde de moto… Tel est le palmarès d’Alcyon !
Créée en 1903 par Edmond Gentil, Alcyon était une marque de cycles et de motos de renommée mondiale, toujours à la pointe de l’innovation, de la communication et surtout de la compétition de très haut niveau.
De son côté, Z.L. (devenu Zedel), fabricant de moteurs suisse fondé par Ernest Zürcher, devint incontournable en Europe en équipant
tous les grands naissants de la motocyclette de l’époque : Minerva, Peugeot, Terrot, N.S.U., Alcyon etc.
Ces deux géants lièrent leurs destins en 1907. Cet ouvrage exceptionnel raconte cette histoire et celle de la rude compétition entre
Alcyon et sa rivale Peugeot. Les deux marques concurrentes ont établi le palmarès le plus prestigieux de l’histoire du cyclisme.
Mais au final, Alcyon bat très nettement Peugeot !
Une saga industrielle hors du commun à découvrir dans un beau livre sous coffret richement illustré de documents nédits.


Didier Mahistre, grand collectionneur de documentation ancienne, rédige de nombreux articles sur la moto. Le fonds documentaire
exceptionnel qu’il a rassemblé depuis des dizaines d’années sur l’histoire de la moto française et notamment Alcyon a été déterminant
dans la reconstitution de cette saga. Didier Mahistre est coauteur de VAP 1944-1967, le plus sûr chemin sur deux roues paru aux éditions E-T-A-i. Cyrille de Ridder est le petit-fils d’Edmond Gentil et l’arrière petit-fils d’Ernest Zürcher. Dans ce livre, il est le narrateur. Passionné d’histoire
et de belle mécanique, il ne pouvait bien entendu rester insensible au destin exceptionnel de ses aïeux.

Thirteen Tours of France to his credit, eighteen Paris-Roubaix, a stunning series of victories in the world of cycling and motorcycling, including the motorcycle world championship ... such is the record of Alcyon!

Created in 1903 by Edmond Gentil, Alcyon cycles and motorcycles were world renowned...

Alycon 18TER

I recently purchased an Alycon 18TER. Just a fluke as I was looking for a D1 Bantam but saw this and thought it was pretty!

If you google Alycon 18TER in images the first image that comes up is my bike. There are two other examples of the same bike and other pictures are unrelated so I figure its fairly rare.

According to what I can find it was made in 1948, it was a prototype only made in that year, its 125cc. The twin port head is also interesting!

I also noticed you dont have one in your gallery so feel free to add it if you wish!

Anyway any help is much apprechiated!

Alcyon motorcycles
I have found an old Alcyon, belt drive, two speed, 200cc four stroke side valve motorcycle. It has footboards as well as pedals to start the engine. I believe it to be between 1918 and 1924. I do not have a photo as yet. Could you give me an idea of what the model may be of its value. It looks in need of total restoration, but the engine turns over and it seems to be all there. Your help would be much appreciated. Regards, david
