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. 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 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.

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

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.

Rough translation:

Thirteen Tours de France to his credit, eighteen Paris-Roubaix, a staggering and unprecedented series of victories in the cycling world and motocyliste, whose first title of world champion bike ... This is the track record of Alcyon!
Created in 1903 by Edmond Gentil, Alcyon was a mark of cycles and world-renowned motorcycle, always at the forefront of innovation, communication and especially the competition of the highest level.
For its part, Z.L. (now Zedel), Swiss motor manufacturer founded by Ernest Zürcher became inescapable in Europe equipping all major emerging from the era of motorcycle Minerva, Peugeot, Terrot, NSU, Alcyon etc.
These two giants tied their fates in 1907. This exceptional book tells that story and that of the stiff competition between Alcyon and his Peugeot rival. The two competing brands have established the most prestigious palmares of cycling history. But ultimately, Alcyon clearly beats Peugeot!

A SAGA industrial uncommon to discover in a beautiful book Enclosed richly illustrated documents NéDiTS.

Didier Mahistre, great collector of ancient literature, wrote many articles on the bike. The holdings
Exceptional he gathered from decades of the history of French motorcycle including Alcyon was decisive
in the reconstruction of this saga. Didier Mahistre is co-author of VAP 1944-1967, the surest way on two wheels appeared Editions
Cyrille de Ridder is the grand-son of Edmond Gentil and the great-son of Ernest Zürcher. In this book, he is the narrator. History buff
and fine mechanics, he could of course remain insensitive to the exceptional destiny of his forefathers.

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
