It used to be "orange bike," "green bike" and "the fixie," but I just took most of the components off of green bike (an old EF Schwinn) and put them on a black frame (old 4130 Schwinn). Now my commuter has a black frame, wheels, hubs, bar tape, saddle, fenders, chainring, etc. "Darth Vader's bike" keeps coming to mind. I guess I need a black cape and when I pass people, instead of saying "on your left" I'll say "I have you now."
