Guys,
I am a model engineering enthusiast, and getting now in love with motorised bikes ;-)
Next project will be to adapt one of my engines into a bicycle frame. It will be a 90cc 4 stroke engine.
Clear up to now is, that the "drive train" will be a belt to the rear wheel, with the beautiful big pullys on the rear wheel, like many vintage bikes have. What is missing at the moment is a good idea for the clutch. I don't want to use a centrifugal clutch, it has to operated by a lever or handle.
Does anbody of you vintage guys has a good idea for the clutch? Maybe some of you can provide photos? That would be great. I love the "open design", where you can see all the parts moving. I thank you very much for the support.
