I am at work and without pics, but I have been commuting with a single speed for about a year. It started out as a winter project designed to not mess up my "good bike" in bad weather and relieve the boredom of New England winters. Now I like it so much it has become my primary commuting bicycle. I recently switched over to fixed gear. It is scaring the hell out of me sometimes, but it is a blast. The bike is a spirited teacher, and it points out your bad habits with the bicycling equivalent of hitting you with a ruler. I never realized I coast so much…
