I know that Cleveland, my original hometown in Ohio, is pretty much flat. I therefore, consider it as a really great city for a single speed bicycle, since hills are rarely encountered. I also consider NYC, Chicago, and just about the entire state of Florida, as basically flat, and subsequently, primary terrain for single speed bicycles. These regions, I personally consider as the best for single speedsters, due to the absence of a bunch of hills.
What about your city?....Is it flat and easily traveled on a single speed?...Do you have a bunch of hills, but still enjoy taking the hills on your single speed?
In your opinion, what are the best single speed cities from either your personal experience, or from what you've heard?
