That’s a street skateboard. And that’s Swiss skater Simon Stricker ripping down Bernina Pass on his back two wheels. Stricker covered 2.1 kilometers while averaging nearly 20 mph (his high speed was 27), all while holding a manual. Dude has some serious balance. “As far as I know, this should be a world record,” he said. Hard to come up with many people who’ve attempted the mark.
