Thanks all for the comments. I am going to check it out farther and see what actual size I need. The one given to me is a 26" tire size and it is a walmart type bike. I think I will enjoy riding more with one than with a high framed one. Looks like I need to visit my LBS and check what he has to offer and try one on for size also.
For me, riding a bike is a lot easier than walking since I don't have the weight on the leg. I don't normally stand while riding. Just sit and pedal.
I am 5'9" and 155 lbs.
Are we having fun yet? I sure am.
