Thanks Max-a-Mill! The one time I tried a fixed gear bike, I almost killed myself. I had never ridden fixed before, didn't realize how difficult it would be to STOP if you'd never taken one for a spin.... it wasn't a good experience! So, at first, I will be riding the Redline as a single-speed. When I have some time on a weekend to experiment, I flip the wheel over and try riding fixed in a parking lot somewhere. Everybody raves about fixed, so I'm sure I could get into it if I practiced, and I'm grateful that this bike has that option. In time....all in good time.
