This is a video of well-balanced (like a healthy breakfast) BMX rider Mike “Hucker” Clark (great nickname, mine’s Puker) riding around a skate park while standing balanced on his bike’s handlebars. That looks intense. For reference, if I’d tried this I would have had a lot less teeth (and blood and unbroken bones) after about a half second. How he didn’t fall into one of the pools and pull a Humpty Dumpty is beyond me, but I suspect it involved really trying hard and believing in himself, something I know a lot about, but have never practiced.
