The Griffon brand was the result of cousin Eugène Peugeot trying to get out from under an agreement with cousin Armand Peugeot to not produce motor vehicles after they split up the Peugeot business into a bike manufacturer (Eugène) and motor vehicles (Armand).

Griffon is mainly known as a motorcycle manufacturer, but apparently the brand was used for bicycles as well.

It all originates in Zürcher & Lüthi looking for a manufacturer of sturdy bike frames for their clip-on engine. Z.L. made a deal with Eugène, and were renamed 'Zedel' as that sounded more French.
