RR -The peddler/cyclers I've seen are all under $50, but none of these have an adjustable resistance. (I wonder if anyone makes one with that feature?) I've heard that it's more like being in a recumbent position and they do have a tendency to slip away. Either placing it against something stationary or a mat with some gripping properties seems to be recommended. I was thinking about getting one so I could get some exercise in while watching TV/folding laundry. I spend a lot of time doing my least favorite chore so I might as well feel like I'm doing something productive.
