For those unaware of it, The Raleigh Chopper was an iconic 1970's gear-jamming death trap that was inexplicably popular at the time despite its many numerous design flaws. The most dangerous of these flaws was the center-mounted gear-shift and its tendency to jam at the most important moments. Having survived the entire decade riding one of these death-traps, I recently decided to get one to tinker with and see if I could improve it with the inclusion of more modern components, but I have been unable to find a complete one, only a few assorted parts. Has anyone seen one of these much-loved dinosaurs for sale online or offline ?
