Matt Beringer's New Backyard BMX Setup How to Ride BMX. Matt Beringer is a BMX legend known for his backyard BMX paradise. He is the only person in the world to ever have a Water Slide in his backyard that goes into a set of dirt jumps. In the event of moving, Matt had to tear down his famous back yard. Don't worry though, because he brought the waterslide with him and built a new paradise. I got the chance to visit Matt Beringer's New Backyard BMX setup and film for How To Ride BMX while I was there.
