Here's the deal...
gravity-bike.jpg

Build one of these http://www.instructables.com/id/Gravity-Bike/ using an existing bike or from scratch. 20" wheels only.

Make it ratty and stylish as you can BUT you must post a video or photo proving you rode it using gravity only at a speed of over 35 MPH before September 12 (my birthday.

If there is any interest, I will post up my before photo here and follow with a build. If not, I'll start a regular build thread.

Come on and join me. I double dog dare you!

20 and under is fine. Don't know much about drift bikes, but if it is under 20 inches and gravity powered, then it should be fine.

35 seems like a fair speed to me, but if you don't have the hills for it, 30 is fine. Lets get as many people as possible in on this.

Who is in?

since school is out, i started a mockup. the black will be wood panels, one in the front, and two in the back. possibly a short cafe racer style fender, and really short triple trees. some stuff will be cut off tommorow. :roll: tires and rims are waiting

the knobby tires on the front are goig to go on, and possibly front rims on both sides and just brakes in the back. would have to go over bars at this level. bare metal is looking pretty good from here
