Last weekend I saw this neat bike at the beach. The frame doesn’t look like anything special, but the wheels, tires, brakes and other components have clearly been upgraded. Attached to the lower end of the frame is what appears to be a chainsaw motor, which drives a heavy duty chain set on a gear on the left side of the rear wheel. It seems that the traditional features of the bike are all intact. The gas tank probably holds enough gas to ride for several hours. Though the exhaust is directed down and away from the rider, it’s probably a loud ride.
I shot several pictures, but have no info on the build.
