Re: modular bike design
well if its electric the motor mounts on the swing arm im working on a 2 speed transmission for it it defaults to the higher gear (( normal for running up to 60 mph) and has a manual lower gear , pulling the lever will disengage high and low takes over). for gas it has a tensioner , the movement at the pivot is so close to where there is a jack shaft that you could get away without a tensioner but better to have one then not. there is still quite a bit of work to be done on it before its even close to done. all the little details lol.
My bike is a Hybrid, It burns gas and rubber
