I'll start us off with my Grant's department store bike. It was found in a scrap pile by a friend and I've revived it with a nexus 3 and parts from six or seven different bikes. I have had it for almost three years and am coming up on 1200 miles on this. It's ugly enough that a cheap lock works fine. The idea is whenever something breaks I'll replace it with something better, and eventually I'll have the best bike.
