I don't follow the bail out gear on the flip side of the hub.
In my theory if you only have the one cog that is what you are going to ride. Uphill, downhill on the flats , in the wind. It doesn't matter. If you have a gear to switch.....well that is going to mess with your mind. You are always going to be thinking ( tis too tough better use the bail out).

Well thats just how I feel.
