if you smile, brush your teeth, don't stink too much, walk with a bounce to your step you won't look like a bum, just a weathered bicycle rider. If you've never worn a beard you might be surprised to find that when you're in a bad mood or tired you will get more wary looks than you did before when clean shaven, especially from children. I had a beard for the last three years and noticed that happened more often. I used an electric razor until I was 25 but didn't have much of a beard. When the screen on the electric razor broke I switched to a disposable razor while looking for an electric and discovered pretty quickly that shaving in the shower was less bother than buzzing in front of a mirror. I tried an electric razor after a few years and found it more irritating than the razor. If you want to shave on a tour it's not difficult and the three bladed disposables with the soap strip don't weigh much.
