Hi
I am a 5' 10" with a 30" inseam guy who would rather ride a woman's bike.
I got used to them in Amsterdam. I have back issues which makes an 'upright' ride important, and I really like suspension. This is primarily for street use, but the roads here are poor. I once had a Jamis that was stolen, it was little small but a step in the right direction.

Can anyone recommend a bike (and a size, I am thinking at least 19") for me?

I need to buy used and my price range is $200 max.

Thank you very much.
