When I was little, I had a Mean Green Machine. I am pretty sure whoever invented it was out to maim kids all across the country. That big wheel/death machine hybrid would do spinouts at will. The downside was that it would also throw you off in about a second. It's a good thing that kids are not fragile. If you had one of these toys back in the day, a new adult version with a big engine from a Harley Davidson motorcycle can be yours.
