I'm glad someone revived this thread. I am an old lady with bad knees. Regular bikes hurt my back so I tried a recumbent bike and it was a big improvement. Someone said it helped with knees. I had an old used one that the digital readout didn't work.

I saw an ad for the Teeters Freestep and wanted that because it included arm movements but the price was a little high for me. Instead I got a Sunny Health and Fitness Crossover Recumbent Bike. I love it. It is gentle on the knees. Very smooth movement and comfortable. Another good thing for an old lady, you don't have to step over a center bar to get on and off. It's completely open to the floor. I use it daily and highly recommend it.
