Default Re: what did you do to your motorized bicycle today?

Dangit, now your gonna beat me to it, eh? lol

Would be wide but perfect for our thing.

Why couldn't you rig up a CVT 'transmission' from an old MTD riding mower? It's just three pulleys with the center pulley having a sliding cone to vary the front to back gearing ratio........ > <> <

Instead of having a chain final drive, it would be a belt. something like the old Snapper riders or old Jacobsen push mowers used. A rubber wheel that moved in or out on a pulley to vary the speed?

You're never lost until you run outa gas.
