Query: Great economical pedal exerciser

This is a decent piece of equipment, especially for the money. Although you do need to sit up higher than you normally would at a desk or chair, it's a nice way to keep moving and burn a few calories while you watch tv or surf the Internet, or as a way to keep active at work. I purchased a second one as a gift for my elderly mom, who needs a simple way to exercise at home. Well worth the price!
