This bike was made from two identical BMX bikes from the trash. I used the fork from one by cutting off one leg and welding it to the seat tube for the rear pivot point. I used the top tubes and head tubes from both bikes and fastened them together by flipping one upside down and welding them together. The rest was pretty simple. This bike is sooo fun to ride. You can do so many fun things with it and it only takes a couple of minutes to get used to it. In a half a hour you can do tricks like a pro!
