I wanted to bike-commute to work for a long time, and it didn't take long to get the motivation. BF was a huge help, and it was quickly apparent from a maintenance and fun perspective that going fixed was the way to do it. So I decided I'd go fixed and bike-commute to work. Bought a Schwinn Le Tour on ebay and converted it. It only took a few months of riding fixed to be completely sold on the experience, so I jumped in completely and built up the Paddy Wagon. I love having it in my stable, and actively include it in the rotation, including commuting, bar hopping, short errands, recovery rides with the girlfriend, "training," whatever. Heck, spent half an hour on the rollers on it yesterday (all the time I had+weather).
while I don't bike-commute as often as I could or should, it's 98% always on the fixie. I just feels propah.
