My commuter among NJ/NYC subway trains for the last 2 years:
Riding among bumper-to-bumper traffic, I keep the bike size small to make myself a smaller target.
Super narrow handlebars to travel between car mirrors.
No locks, because I don't really leave it out of sight for extended amount of time, with the bright color frame, mismatch grips, amount of dirt & grime on it; the thieves don't really care for it.
Rubber bands and toe straps that serve as parking brakes; that have deterred theft a few times.
For $125, this bike has been a good value commuter.
