i dislike fixie riders that ride without brakes but dont know how to stop without them. ive seen groups of hipsters riding up to busy intersections and grabbing onto stop signs to stop. if you're going to ride fixed, have at least a front brake until you get used to stopping with the pedals.
i also think no brake fixie riders with flat pedals are retarded. get clipless or toe clips if you need to use the pedals to stop.
personally i wouldnt like to ride fixed as a commute, because ive already been hit by cars three times commuting with brakes. without 'em its just one more thing you've got to think about and hope your reflexes will remember to stop with your pedals. also your tendancy to skid is much higher, and therefore worse for emergency braking.
lastly dont like the idea of pedals hitting the ground when you take tight corners (especially at speed).
all this aside, my next bike will be a (very bling)fixie- more as a sometimes bike (or pub bike i believe theyre referred to as), because i would like to develop the extra bike skills, and because a nice fixie is a very beautiful thing. I like to customise my bikes, but i do it because i enjoy it and i like beautiful bikes, not as a "travelling billboard for my ego"
as much as i dislike people just jumping onto trends because they're trendy, i think cycling is great and people doing it (whether riding fixed gear or not) should be encouraged rather than yelled at or mocked.
i do dislike however elitism in fixed gear riders. as far as i am concerned all cyclists are created equal, whether riding a super bling fixie, full carbon road bike, stp or garage sale raleigh number.
i do however have a certain soft spot for cute girls on hot bikes.
