Bottom line

The Bowflex TreadClimber TC20 combines the benefits of a treadmill, an elliptical and a stair stepper. Many users agree that it provides a very challenging workout and is effective at burning calories. It is, however, one of the most expensive stair steppers on the market (*Est. $3,300).


One of the most expensive, with a workout to match: It is nearly unanimous that this product is overpriced. One review on states, "… you have to be completely sure this machine is what you want, otherwise what's the point in wasting perfectly good $3300?" It should be noted that it is also the general consensus that this machine will give you an above average workout. One owner on said, "… I've never had [a] workout this good!"

The TC20 combines the motion of a treadmill, an elliptical and a stair stepper through a pair of mini treadmills -- one for each foot -- pivoting on a hinge in the back. As the user walks on the "treadle," it moves vertically, creating a sort of climbing/stepping motion.

Some users say that the machine can be a bit noisy. So if you're operating it around others, it may be a nuisance. Its 42-inch foot treadles should be more than large enough to fit most people. The Bowflex TC20 comes with three preset workout programs, a backlit LCD display, heart-rate monitors on the hand grips and a speed range of 0.5 to 4.5 mph. While the TC20 has more features than some lower-end trims, the TC5 and TC10, users say they would expect more for the price. Also others complain that the maximum speed is not satisfying.

Ease of use

Surprisingly simple for state of the art: The Bowflex TC20's lack of features makes it well suited for those wishing to focus more on the workout than on the LCD monitor or other luxuries. Reviewers claim the benefits from the machine are about equal to those of running. Thanks to its elliptical motion, it is also much easier on your joints than a treadmill. If you have joint pain, then this might be taken into consideration. The machine is big and bulky, weighing 215 pounds and measuring 51 inches long by 30.5 inches wide.

The TC20 utilizes a unique interactive program called G.O. Coach. This program allows you to track your progress, set personal fitness goals and compare results with previous workouts. One review on said that this feature is not worth the machine's hefty price tag. Overall this machine is not a substantial upgrade from its predecessor, the Bowflex TreadClimber TC10.


Seems well built, just a few bad eggs: Of the small handful of negative reviews on the Bowflex TC20, the issues mentioned seem to be factory defects or improper assembly. In one instance, a reviewer on said it was "tough for the technician [theirs] to put together without the owners manual." However, negative reviews on this machine are scarce, and a majority of users say that the TC20 seems solid and stable.

Customer service

Excellent warranty, questionable service: The Bowflex TreadClimber TC20 comes with a three-year total coverage warranty. This means that if anything should happen to the frame, components or mechanical parts within three years of purchase, the manufacturer will fix it. Instances of this being needed appear to be rare, but in the few cases that something has gone wrong, the company seemed to be less than responsive. In one customer's case, the trainer arrived unusable (even after spending $249 to have it assembled, according to the customer's review). After being passed around on the phone by the company to no avail, the customer wrote on, "I don't think I will buy anything from Nautilus again. I feel I should have my assembly cost refunded so someone will not allow this to happen again."
