Do you need to carry items and don't like backpacks?
If so a Pearson Touche or another practical fixie frame with rack brazeons is handy. Or you can convert a frame with long dropouts.
I think Genesis may do some practical single speeds too.
I run around in flat Belfast on 48/17 (hills can be tackled with that too if needed...though the cavehill is a bit of work on that...) and I have to say I enjoy cycling fixed over single speed as you can use the rear wheel as a flywheel and adjust your speed for traffic lights. Saves on brake blocks / rim wear too :P
Apparently not a thing but I'm sure I can feel a difference too, with fixed. You get it up to speed and there's that... inertia? I guess, where it seems happier staying at speed than a geared bike. Like you put effort in to get fast, but then less effort to stay fast.
Why do you think a fixed bucks you off if you don't relax your legs? The momentum stored in the rear wheel isn't let go by freewheeling so by timing it right you can re-use some of it :)
(no doubt tester can explain this in perfect terms)
