Historically, women have had a tougher time fitting themselves for a quality bike. And shorter women often find it even more difficult. The main problem is that even though most women are smaller than men, they often have longer legs. Shorter women will find that a frame with an appropriate seat tube length will leave them unable to reach the handlebars. Many good manufacturers are making women's bikes to accommodate body differences. Just keep on testing bikes until you find the right fit. And don't only limit yourself to women's bikes either. Try everything. Being overstretched on a ride will cause stress to your arms, back and shoulders.
