But selecting the right bike frame starts with the assumption that you can stand over your top tube with clearance to "straddle start" with or without the lower bar like a women's bike. More clearance for mountain bikes due to the uneven starting surfaces, and less for road bikes where you have a flat pavement as your support.
The ultra lower bars on a women's bike tends to be more of a benefit if a women is riding with a skirt or dress on. The wife likes that just for that specific reason as she can wear any clothing she wants without worrying about it when we go biking.
