The bike man is the guy in your hood who drives around in an 80's full size pick-up truck or rapist pannel van and picks up abandoned and broke bikes from the garbage, he then fixes them and sells them. Dispite being the "bike man" he(or she, although rarely she) is often too portly/out of shape to ride and dosen't come of as a cyclist. Great source for vintage road bike frames to convert to a "fixie".
Q: Hey John, where did you get that sweet Peugeot fixie?
A: I bought the frame off Dave the bikeman, and built the rest myself.
