physics of a bicycle.

so...this week's photo's are a bit more of a personal nature. my fiancee recently bought both of us bikes for our third anniversary, as kind of a present for us both to enjoy since we decided to quit smoking on our anniversary date and start working out to get in shape for our wedding next year. i've developed an obsession for riding all over again, and i've decided to convert an old ten speed of mine into a fixed gear so i can have a bike to do tricks and build my endurance on. these are a few photos of my Schwinn Sportabout.
