What size did you get? It looks like the women's sizes are offered in xs (26 inch wheel), petite, small and tall and the bike not marketed as a women's bike is offered in xs (again, a 26 inch wheel), small, medium, large, extra large and jumbo. The smalls seem to be the same geometry, just looking at the geometry chart.

The colors for the women's is different. It looks like the saddles are different. Otherwise, unless I am missing something they look the same.
