Re: Its Electric Start
I think that the engine is used for slowing down. Since it is belt drive, with a manual clutch (not centrifigal) just like a lawn tractor, as you lower the throttle, the tractor slows down instantaniously, (but in this case the bike, or whatever it is considered to be slows down). Once the rider gets down to a crawling speed, they can disengage the clutch so the motor will keep running and by that time, they can put their feet on the ground at stop signs, traffic lights, whatever. Very creative build however you look at it.
