I own a woman's specific design bike made by Giant. The OCR1. It's about $1200. That was almost heart failure for my DH when I bought it, but I tried to console him that it wasn't the all carbon girl I really wanted for double the price. Despite her not being all carbon, that will be my upgrade one day, I am happy with my Giant. I looked at a Trek Pilot too, very similiar, but something about it just didn't feel as good as my Giant. So, what girls have said about trying different brands holds true. The other two brands you posted about I do not have experience with. Also as posted, I like the pics of the Orbea Diva (never seen in person). I think there needs to be a cycling Santa for big girls that just leaves bikes for free under the tree... sorta like for kids. Wouldn't that be grand? Good luck with your decision!
