This only works for men. I shave my legs because I'd look gross in pantyhose otherwise, and obviously I can't grow a beard.
And why no category for hub gear bikes? Do they get lumped in with hybrids or with fixies? I call my Metropolis my "stealth" bike. While cruising down 10th ave. on the way to work one morning, I could hear a derailleur gear shifting behind me. So I shifted up. One block later, I could hear it again. Shifted up again. This went on until I got to a street where I needed to turn right, then I looked back and saw a bewildered young woman staring at me from the saddle of a touring/cross type bike about 30 feet back. Without the visual cues of a derailleur or the sound of a shift to go by, she had no idea I was also shifting up.
