I got the video "Judgement Day" for christmas. It's got todd colbert and a whole bunch of other guys doing crazy tricks on bikes. i know i would probably kill myself trying to do some of those insane stunts but there was one stunt i really want to try. I wanted to do that burnout/donut i've seen some guys do. They stand up over the bike (or sit on the handlebars) and smoke the tire while going in a circle. I imagine it's pretty hard but it looks really cool. i don't want to try yet because i want to know how to approach it right. I don't want to smash up my bike either. do i dog paddle it around in a circle first or can i just go right into it? anybody know how to do these?
