I built the homemade Noped in the 1960's. It was made from a bicycle, a 1 HP 4 cycle Briggs and Stratton lawnmower engine. It had a speedometer, lights and a drum brake. It did 30 mph with a centrifugal clutch. Back in the day, there was no self-service gas stations. I would "piss off" the attendants when I would fill up the one pint tank for less than a dime and often for only a nickel. The bike was stolen on 1968.
