I do see more men than women on my daily commute. When I'm doing after-work riding do I see a lot more women. I'll add that I probably fall in the "girly" range; I like make up and LOVE riding in my skirts (but I wear spandex & tank tops for my commuting). It's possible to commute and still look good; where there's a will there's a way.

I agree with the body issue thing too. One of my close friends likes to exercise and does what she can to get fit - but her body type doesn't make it easy. The reason she told me she didn't want to bike was that she was "too huge" for it, and didn't want to look like a joke. I did my best to convince her she was worried over nothing, and that all sorts of people bike. Oh the other hand, we do all know people judge us. I've seen some comments on other bike forms....

I have no comment about juggling kids, not too many people I know have them and there is no kids/cyclist overlap in my friend circle at all.
