So you don't wear your sister's pants or a white belt, don't ever feel the need to do bar spins, and don't like to destroy those high end tyres by skidding them.
You might have fenders and racks on your bike because it rides in the rain and has to haul your crap all over the place and it might even have some bad ass lighting or studded tyres if you ride it in the winter.
Your bike probably runs brakes.
Some would say that a fixed gear is not a utilitarian machine due to it's lack of multiple gears but I disagree... this is my all weather commuter / tourer and what I will be riding after the apocalypse.
