I have had both of my knees replaced and have lost range of motion in my right knee. I found a wonderful bike called a Townie built by Electra Bikes. The bike is made with a slightly extended frame to allow for the loss of range. The bike extends the pedals a little bit forward. You also sit upright on the seat and when stopped you just put your feet down. I love my bike.
I bought it last May and in just the last few months I have logged over 300 miles on it. The bike has been one of the best things I have ever bought. I love it and can't wait for the weather to clear so I can ride me. I live in Ohio, so the weather is very iffy.View Thread
