1.)Go either garbage picking or garage shopping and retreive yourself up a 20 inch BMX bike.

2.)Strip the entire bike down so all that is left is: the frame, the fork, the headset, the stem, the handle bars, a seat post, seat post clamp, a seat, and grips and bar ends (if you like the luxury).

3.)Go raid your dad's work area and find about 5 or 6 of his greasiest shop towels and confiscate them. If he asks, you're just borrowing them.

4.)Fold the towels into like halves or quarters so there is a thick chunk of towel. Now fold it onto the rear drop out and front drop outs. Duct tape into place. Make sure the drop outs won't poke through the towels after a couple jumps. Make layers if you have to.

5.)Repeat step #4 for any other sharp edges on the bike. What I did was pad the sides of the bottom bracket shell because it hurts kicking the bare metal for tail-whips.

6.)Tighten down all your stem bolts and seat post/seat bolts because beleive me, it slips right away! I'm still thinking I should weld the handle bars on so they stop moving. Also put on some bar ends so the edges of the bars do not rip your tramp.

7.)After you're done, double check and make sure you don't have any sharp edges sticking out. It is very important you do this or you will be replacing your trampoline very soon, and you can't just buy the tarp seperate. You have to spend $200 on a whole new trampoline.

8.)Get your lazy ass on the trampoline and enjoy, but it will wear you out quickly.
