don't jump right into it with a trial bike, get a bmx bike or use your mountain bike and just work on doing stuff like that, i've been doing that a little with my xc bike, just hopping up sets of stairs and riding some urban and once you get good at that then look into getting a trial bike but i wouldn't rush into it. trials is one of the hardest forms of riding
just make sure you have a nimble bike with REALLY good brakes

"People always ask me, 'is it worth it, getting hurt that much?' and the answer is yes, I would do it all over again, have six more season ending injuries in the next 10 years to keep doing what we get to do, there's nothing better than sliding down snow and flying through the air"
