Many time Trials bike world champion Toni Bou having some fun.

Always found trials more interesting than motocross.

I remember, as a kid, in Boy Scouts, we were hiking to the top of one of the one of the mountains in or near the Presidential range in NH...which one escapes me but it was a ball buster with lots of big rocks, roots and tight trails. When we finally got to the top were were exhausted and resting and all the sudden hear engine noises and two guys on tills bikes appeared, we were amazed by this as we had never seen this before and they put on a really good show for us.

I love trials bikes. Like a mountain bike with a motor.

Never understood why this isn't more popular in America. It is huge in Europe.

The skill, grace, and courage these guys have is insane. I get scared riding a bike down steps.
