I believe that Bendix was the company that made the hub gear that you could shift with a small backpedal. I don't know how it worked or if it worked but I do know that in the 60's this system was heavily advertised in the pages of Archie comic books. Archie and Veronica said they loved the system. It was in its way the first infomercial I had ever seen. I would switch over to that system even now if I could get a date with Betty or Veronica.
