I would like to get get her a small unisex bike but she likes the compact geometry of the women specific bike.
Seriously, what does that even mean? Small frame and shorter bars perhaps? Less reach than is now the norm?
Personally think men’s vs women’s razors is the same analogy. Ie. Pay more for a women’s razor…. because it is a women’s razor and possibly pink.
All that said, buying a bike based on your own wants, logical or not, for someone else can always be a minefield.
Id get her what she likes and finds comfortable.
Will she mind if the hubs are a lower spec or such? That’s a genuine question and not based on sexual stereotypes. Ie. For me it’s all about the frame and current standards, the rest just gets changed as it wears out anyway.
