I'm sure we're on the same page, Mike. I know that S-A made fixed 3-speed and a fixed 2-speed hubs. I don't know if they were used widely or if they were successful or mechanically reliable. The freewheeling S-A bicycle hubs were wildly successful and popular. I do know that the backlash exhibited by multi-speed, fixed-gear epicyclic hubs is unacceptable for use on a unicycle whereas it would not even be an inconvenience on a bicycle. I will concede that reduced gear epicyclic hubs for unicycles are theoretically possible but I also know what the engineering gymnastics are that are required to realize it.
