Dr. Bonusgrind AKA John Mayo coming through with grind after grind of goodness that was filmed over the course of 2016 all along the east coast. All four pegs get beat to hell in this one and John is no stranger to sending X-Up grinds on everything from steep rails to big ledges. This is a really good watch from start to finish, so get on that play button and check this BMX video out already!
