yeah that stuff is pretty crazy! Ryan Leech (my bf's idol) is crazy awesome with trials. He can ride chain links and bunny hop of 2 inch rails many feet above ground and all that insane stuff.
My BF used to do trials but his knees started to swell and he would be in a good deal of pain. So he took a break but I think he's gonna get back into it. I'm so envious b/c I can't endo, bunnyhop, and all that other stuff like he can.But I do have more speed than he does
