I set up my Steamroller as a fixie, the simplicity appealed to me. It was fun to ride fixed, changing speed was done without conscious thought. That said, riding down big hills SUCKED (especially when my feet got bounced off of the pedals.... Bunny hopping big pavement heaves and potholes SUCKED.
Put on a coaster hub and loved it... a coaster brake stops much better than backpedaling.
