I have . I actually gave my motorized bike to someone who desperately needed transportation to work and back every day. I demonstrated how it works, then he got on it and fell over sideways. I asked Do you know how to ride either a bicycle or a motorcycle. Yes he said. It went down hill from there on. After about 4 hours of him riding off and then walking the bike back. Couldnt start it . Couldnt steer it. and on and on. He gave it back. I got on it and drove it around trouble free for about two days now. LOL. I think he wanted me to give him a car . No good deed goes unpunished.
