Hi catherine, I bought a used beach cruiser at our Salvation Army for $70.00. I absolutely love it. It's got a foot brake, and with the way it's designed, you can sit up straight. I take mine on the bus, too. It's a little bit heavy to lift on to the bike rack, but doable. I also had a mountain bike that I bought at Walmart. It was inexpensive, and a great little bike. It was nice and light. The hand brakes are easy to use. Unfortunately, mine got stolen at the train station. Have fun on you bicycle, whatever you get.
