Get dumped, ten you can have as many bikes as you like. I'm at 3 right now and am eyeing up a potential new road bike, and a single speed. of course I don't know how I'm going to pay for them yet though but that's not important.
You can then also flirt with the new girls that you've just met now that you're single. make sure they live far away like, let's say Dallas, Phoenix, and Boston, so that you don't get tied down to much, and new riding destinations appear.
Come on, everyone's doing it! Well I am!
