Stamina 5325

If you can't afford to spend a lot on an upright exercise bike, the Stamina 5325 is worth a look. It can accommodate users up to 300 pounds and has eight resistance levels so you can vary your workout. A handgrip heart-rate monitor and six workout programs are also included. Users say the Stamina 5325 is solid and feels sturdy while pedaling. Owners report a good variation between the high and low resistance levels, and the adjustable seat accommodates both short and tall users. However, some say they wish the pedals came with straps for a more secure fit, and a few owners say there were components missing when the bike was delivered. If you can afford to spend more, the Schwinn Airdyne (*Est. $620) gets the best reviews among upright exercise bikes. The Airdyne uses an air-resistance system, and reviewers say it's durable. A lengthy warranty is another plus. The Stamina 5325, on the other hand, has a one-year frame warranty; parts are covered for only 90 days.
