Whenever I spend any time in a city I'm always checking out the fixies people are riding and I've always had a desire to build one up. BF did speed that process up and I finally got an old Puch converted, which I've been commuting on for about a month now. It was a pretty logical choice for me because my commute route is ironing board flat and on multi geared bikes I pretty much stayed in one gear the entire time anyway.
