UPDATE: The Mobia is no longer on the market. It has been replaced with the Bowflex TreadClimber line. After reviewing them all, we recommend the TC10.

The Nautilus Mobia is classified as a “TreadClimber”, or one of the most recent innovations in the fitness market.

TreadClimbers are designed to offer three body changing workouts with one easy motion. The result is a simplified exercise that delivers optimal results.

The Nautilus Mobia burns calories up to twice as fast as a treadmill (according to Nautilus) and is surprisingly affordable compared to standard treadmills.

“3 Body-Changing Workouts, 1 Easy Motion.”

The slogan reads for the Nautilus Mobia and frankly it’s best way to explain the technology of the TreadClimber.

The Nautilus Mobia features a similar walking motion to the treadmill. However, since the trainer works independently you also step up like a stair climber. When you combine these two actions you get a more intense workout with the smooth, low impact motion of an elliptical.

Thus, you could say the TreadClimber is the offspring of what a treadmill and elliptical would produce.

Workout Programs

The Nautilus Mobia offers five individual workout programs or functions:  Speed, Distance, Time, Total Calories, Heart Rate.

While the workout variety may not quite compare to what you can find on a stereotypical treadmill the workout functions are more than enough to deliver quality results.

Everything is tracked really nicely on the LED display with five separate readouts.

TreadClimber Features

The Nautilus Mobia features a maximum speed of 4mph with the aforementioned 3-in-1 motion that produces amazing results at a walker’s pace. Consequently, the ability to walk with high-end results reduces impact on the joints and muscles.

In a study conducted at New York’s Adelphi University, Mobia modality burned up to 2x more calories in 30 minutes than a treadmill at the same speed.

Along with the exceptional performance, the Nautilus Mobia features 12 levels of resistance, Chest Strap Heart Rate monitor, accessory tray and Quick Controls. The TreadClimber is also very portable at 200 lbs. and equipped with transport wheels.

Warranty & Guarantee

– Motor: 2 Years
– Parts: 2 Years

– Labor: 2 Years

The TreadClimber makes a lot of sense. Why not get similar, even better results, when compared to a treadmill with less impact on the joints and muscles?

If you agree than the next step is to compare the best TreadClimbers on the market and the Nautilus Mobia is one of the best. The TreadClimber is not only one of the most affordable on the market, but highly effective and developed by one of the leaders in the fitness world.

UPDATE: The Nautilus Mobia has been discontinued in favor of the more popular and updated TreadClimbers.

We have reviewed all the TreadClimbers, and our staff pick is the Bowflex TC10.
