This 3Rensho Cyclone is one of the rarest and most valuable bikes I have ever restored over the past sixteen years of collecting vintage bicycles. The story began for me on the docks of Red Hook, Brooklyn, but the story of this bicycle goes back much further in time. After extensive research, I’ve confirmed it was made by Mr. Koichi Yamaguchi in 1978 for the NYC Bike Show. This article relates the story of how it came into my hands, the restoration process, and some 3Rensho history. All images in the article are hi-resolution – click them to view the large version.
