Exercise bikes are the old standbys of the home fitness world; they've been around longer than treadmills, elliptical trainers, rowing machines and skiers. Experts say exercise bikes are safe, effective, and as easy to use by seniors and pregnant women as by the most avid fitness enthusiasts. The stress on knees and joints is less on a bike

There are recent concerns about Americans getting enough exercise.  Did you know that an exercise bike is a low impact exercise with great cardio-vascular benefits?  Watch TV, read, or play games while getting much needed cardio exercise.  Our bicycle seats help relieve pain and numbness allowing you to get more exercise, more comfortably.  Please see the growing list of information concerning these issues for men and women.
