Swinger bike in progress

I had two child bikes laying around, so i decided to make a swingbike out of them. The main fun, as you can see, that the frame "swings" on a fork bearing in front of the seat. I tried it, it is actually pretty easy to use, and can do some crazy tight turns, and surprising angles. (If you are crafty, look it up on YouTube, the head angle, and the "swing" angle is important to get right!) I recommend it to every thrill seeking bicyclists, it is great fun!
