I have ridden on one but did not like it at all. They scare me. A man who goes to my chruch was killed on one a few months ago. I did not know him but it was still so sad. There used to be a group of cyclists who did a charity ride each year and they would stop in the store on their way to start ride. Amazing sound to hear all those bikes at once. Even more amazing to see lawyers and other professional people looking like Hell's Angels!! I don't remember what charity they rode for but they raised a nice sum each year.
