I did this video with (banned user) Max Rainey for a BMX contest impersonating BMX rider Kevin Porter. The riding isn’t groundbreaking, but we went to some of the same spots from his videos and did similar/comparative/same lines unicycling instead of biking so it was more based off of that then hard riding.
All he has to do is stop that right arm from flailing about like a commonly used middle age hand weapon consisting of a spiked ball attached to a handle by a chain or cord.
