If you have 13 minutes to waste you will find this video showing 50 weird but creative "motorcycles" fascinating.  https://www.youtube.com/watch?time_continue=47&v=E_yCy0vJQjg

         They left out one of the best: Wild Bill Gelbke's Road Dog.

          This is only one of many websites covering the Road Dog. With some searching you can find videos of it being ridden. It took balls to ride this thing. I believe Walneck still owns it or maybe it's in a museum by now. Bill is dead.

I have seen that thing before.  It is a bit over the top for sure.
