women and children don't use 650c rims on regular sized road bikes because regular sized road bikes don't typically run 650c rims. you see them on smaller sized bikes equipped for everyone, including men, around 5 feet tall or less.
you'll also see a lot of triathlete run smaller wheels to get lower when doing TTs
