Two years ago i bought a "stupid" expensive bike. I questioned my decision but once I started putting miles on it I realized that I made the right decision. The most expensive bike is the one you don't ride. Since upgrading, my annual mileage has doubled and my cost, at this time, is about $1 per mile. At this rate, i'll be at 50¢ per mile in 2 years.
Last year I stopped at a deli and asked the couple, eating outside, to watch the bike while I went inside. When I came out the guy said "that bike looks expensive, how much does it cost?" I told him it was a bit over $2000. He said that's more than he expected.
