So: A neighbor showed up at my door and gave me a bike. It's the famous original wal-mart fixie, with red and yellow rims. It needs a little work--the headset is loose--but looks to be in decent condition. It also has a single speed freewheel. I already have a nicer fixie, a long-tail cargo bicycle (Yuba Mundo), a touringish bicycle with racks, and a multi-speed road bike, and am wondering what good use I can put this bike to. Any ideas?
