The Economics of Bike Commuting [MicroBusiness]

A few years ago, some of my colleagues started commuting to work on their bicycles. Eventually, I realized that some of them were riding longer distances than my commute would be, and I decided to give it a try. The first ride was difficult and took quite a bit of time. But I kept at it and came to enjoy it. I´ve been commuting by bike two or three days a week for the past four years. These long rides give me plenty of time to ponder things, and one of the things I´ve pondered is if it makes economic sense to commute by bicycle. On the surface, it seems like a straightforward question. But the more you think about it, the more complicated it becomes.
