Tweetlike an old school mini bike? lawnmower engine, go-kart tires and all?...pull start?
I've seen these kids, mid-teens, riding a pocket bike around the neighborhood for months. A couple of months ago my wife comes in the room and tells me a guy crashed taking a turn right in front of the house. We're...were, on a corner lot. So I go out there, and he's brushing himself off, checking his wounds. He had a few strawberries, and tore the skin off his palm pretty bad. After I made sure he was okay, I checked the bike out, and that little thing had a tranny and all. It was a little 3 speed.
So, pretty cool little pocket bike.<---point,lol...I told him to wear a helmet, helped him push-start it, and that was that.
He almost got into a fire-hidrant. That woulda been some brain-damage.
