Shorter men (<10%ile) would not buy a women’s bike even if the actual geometry worked fine (usually better) and the saddle could be swapped out.
Club mate of mine from years back (who was 5’6″ according to him, more like 5’2″, and very slight with it, probably weighed under 50 kilos) absolutely point blank refused to get the ladies version of his bike. Even though every component selection and all the tweaks they’d done to shock and fork would have suited him down to the ground. There wasn’t even anything that identified it as a womans bike that couldn’t be swapped in 10 minutes (grips, saddle).
Except, only the womens version of the bike came in that particular shade of paint, so people would know, apparently.
So, he bought the mans version of the bike. And spent a couple of years hating it and hundreds of pounds trying to get it to work for him. Cranks, forks, shock, bars and so on. He even jumped on the bar bandwagon and bought some 800mm bars “to transform the handling”. They got used for about two weeks then sold on at a massive loss.
Last i saw he’s got into road cycling, and is now riding a larger frame size than i do (I’m some 6-8″ taller than him).
He’s also now working for a quite successful bike shop. Has been for 7 or 8 years.
They have their own in-house fitting studio.
