There are many other wonderful sites out there that I have learned a lot from and have a lot of respect for! I wanted to recognize and thank them here.
Bodybuilding.com has a truly outstanding informational database for all things exercise. They provide many great training videos and informational articles here. They are also an outstanding retailer of high quality fitness supplements and accessories. Bodybuilding has been my family’s preferred vendor for supplements for a number of years. Their customer service and shipping speed is superb, as we have experienced time and again. They haven’t paid us to say this, either! They are just really a great outfit.
Best Fitness Advisor provides great information on not only exercise bikes, but many other types of exercise equipment as well.
One can’t forget the ever-resourceful Wikipedia! They have a great write-up on recumbent bikes, which includes a mention on recumbent exercise bikes.
