Just showing off a quick build of my 28″ Hyper Spinfit motorized bicycle. She goes about 30mph and gets 130mpg. Not bad for a 48cc motor.
Initially, my chain was rubbing against the chainstay. So to prevent that, I flipped my sprocket with the indents facing inwards not outwards. Now I have 1/8th of an inch clearance from the chainstay. Just a tip if you have chain rub.

  1. Very nice, could you do some more low end bikes that can be used for higher end things like this, videos? Ex. Walmart mnt. That is now a off road machine
