What matters is the size of the frame, not the size of the wheels. You can ride a bike with 26 inch wheels. I did when I was under five feet tall, many years ago. Go to a local bike shop and tell them where and how you want to ride. They've got people who are qualified to help you pick the bike that's right for your needs. Don't feel overly obligated to buy a bike there. You'll be back to buy other stuff, like tires, tubes, and accessories once you get into riding. I hear they make more money on that stuff than they do on the bikes.
