The Trials riders never cease to amaze me, in these videos. I also watch a few Hill Climb videos. I can't help but believe that a good Trials rider could kind of ease up some of the hills that can't be climbed by riders with nitro burning bikes, with heavily studded tires, and 5 foot long rear swing arms. I would like to see that. I also wonder if the fellow riders, which are helping riders with spotting, and rescuing them and their bikes from mishaps, aren't at higher risk for injury, than the ones doing the riding, at the time.
