I'm building a quad recumbent. I'm a big guy so I need the four wheels. I want something I can have fun on.
I'm looking into differentials but haven't really seen any diagrams or good pictures. I see alot of trikes just drive
one side. If I can't get one that's within my budget then my idea is to attach a cassette to a jack shaft and put
sprokets on the ends then have chains go back to regular wheels in the back. I know this bike is going to be heavy
I'm not concerned right now with that. Any ideas about this would be appreciated.
