I dislike the labelling of bikes to a specific gender.
My road bike & tourer are diamond frames, neither are 'women's frames' and as an average height of 5'7" and shrinking as I get older, I've never found a *need* for a 'women's frame' The only thing I've changed on the bikes is the saddle - as they are very much a personal thing anyhow.
My recumbent is well - a recumbent, so gender neutral design anyhow.
My hybrid is a step-through frame - bought as at the time, it was having a child seat on the rear rack, so at the time, a step-through was more practical than a diamond frame.
There's all sorts of reasons why a step-through frame really, really, really shouldn't be limited to use by gender. Example - a bloke may well have limited leg mobility and prefer a step-through frame. When cycling over in 'forn parts, on the European mainland, in both France & Germany I saw all ages, all genders riding all sorts of cycles. It was a joy to see.
