I haven't seen this before! LOL
If there's a way to upload a video clip of this dude whipping around, please let me know!
Took zooming in to see the guy is sitting backwards on his handlebars...
Outside of a circus and maybe a kid at a skate park I've not seen this either.
The guy was FLYING on that thing! He started on the sidewalk, hopped a curb to get on the road, and then back on the sidewalk after crossing the intersection!
I don't know how someone acquires that kind of skill, but I was damn impressed!
