Suzy,

I ride a Terry bicycle. Terry is a company that makes bicycles for women that are petite. I am only 5 feet tall, I have the Terry Classic, and I LOVE it!!!

Here is their website. Click on "dealers" to find your local bike shop.

www.terrybicycles.com

They also have a place on their website for people to sell their used bikes.
Just click on the "Trade" button on their site.

Hope this helps. If you have any other questions, just PM me.

Lynette
