I'm not a big fan of watching trials but this video is pretty amazing, and the guy almost has a street like style for some stuff. Check out around 2:30 when he rides across the cable he can barely walk on.
The hop gap over the rail too its kind of strange, especially for the big bikes. Now I love all kinds of bikes but I've just never seen the fun in riding street on big wheels, I mean its nice to go fast and getting from point A to point B, but it just feels so goofy doing tricks because of the geometry and wheels(to me at least) obviously guys like this have no problem. I do feel like the bike control you learn on a BMX bike helps on the big bikes though. And either way both are fun as hell!
