Surely that is an incredibly rare ability. Who is he?
The front flip from a pallet stack that precedes it is remarkable in its own right. How he can stop instantly with that much energy behind him is amazing.
It was watching videos of extreme unicycling when I was struggling to learn that made me consider an ordinary person like me should be able to ride along flat ground if stuff like that was possible for the exceptional among us.
Since then I have surprised myself many times, mostly when riding big wheels up steep slopes.
