As the ‘longer legs, shorter torso’ theory has been de-bunked, and women’s proportional variations are shown to be very similar to men’s, but a bit shorter with more weight ‘up top’, I’m not sure that women need different bikes? OK, you might want a bit more compression damping on the fork, and bit less on the shock, but that is pretty easily sorted on bikes with reasonable forks and shocks. Most people who’ve ridden a bit have their choice of saddle/grips, etc. If you buy a complete new bike you make your mind up if you’re going to change out the stock bits or not. It’s one of the nice things about bikes, if you buy a complete one, it’s really easy to unscrew some bits you don’t like, and change them out for bits you do, or have someone do it for you, which any decent shop will, whether you’re male or female.
