I have one of those! I sometimes use it on my bed to pedal my arms out of boredom, even if I've already done my cardio. It's something. I let my son, who is too short for the recumbant bike, even if he IS pretty giant as far as most 6 year olds go(4'3.5" and 75lbs). It's good for when it is too cold or wet for him to go outside.
