I am so happy I get to comment on this question! I was doing this very research for myself not too long ago. I was fortunate enough to have many bikes available to me at the store to test, at the time, and landed on the Electra Loft 7D !
I love my bike and have fit so many women for it as a result. It is so comfortable but not too slow by any means. I keep up with my friends and family all while not stressing out my body!
Hope this helps!
