Adding Pedals Onto a 50cc Scooter?
Just came up with a pretty funny idea. I'm not sure if this has been brought up before, but according to the laws you could throw pedals on a little scooter and it would be called a motorized bicycle by law if you could move the scooter with pedals. You would never need registration, licence, or anything! (Depending on your state). Just a funny thought.
