Treadmill on a UTV
After betting Travis Pastrana that he could run a mile in under four minutes, Jim York and his pals from Channel 199 came up with a cheat code. They welded a treadmill to the roof of a UTV, powered it with a generator, and then took it for a spin. It looks fairly tame on the pavement, but hanging on while doing an off-road jump looks a bit more sketchy.
