True 550 ZTX OP Treadmill Review

True 550 ZTX OP Treadmill

True 550 ZTX OP Treadmill

The True 550 ZTX OP treadmill is the ortho belt version of the True 550 ZTX P.

And unlike ortho belt treadmills from other brands, True’s version doesn’t cause wear and tear that is harmful to your machine.

Is This Your Best Buy Treadmill?

If you really need a huge treadmill with excellent cushioning, then this model is worth checking out. It comes with the biggest running surface currently being offered by True. However, with a price tag above $4,500, I don’t think most people can afford this unit. So if this machine is beyond your budget, I suggest you look for comparable treadmills using our best buy treadmills page.

What You’ll Get

This model boasts a 3.0HP continuous duty motor that serves up speeds of up to 12mph (this max speed is higher than what models from other True home series is offering) and inclines that reaches 15%. So it doesn’t matter whether you’re a beginner or advance runner, this machine can provide you the intensity you need.

The True 550 ZTX OP treadmill has a 22” x 60” running surface. This is the currently the biggest tread belt for home being offered by True. Plus, with its ortho belt feature, this unit could very well provide you the best treadmill experience you’ll ever have.

This machine also features 4 pre-programmed workouts (Weight Loss, Speed Interval, C/V Workout, Hill Interval) with 9 intensity levels each and 3 customizable programs to give you more variety and flexibility in your exercises.

The 10 x 28 LED tri-color dot matrix display is bigger than your average True console(7 x 20). It shows you your speed, distance, grade, time, pace, calories and Mets so you’ll always know whether or not you are progressing.

The manual S.O.F.T. select is still available in this model. With it, you can customize the softness of your treadmill to fit you more through 12 manually adjustable settings.

And finally, this unit comes with excellent warranty. Its drive motor and all of its parts are covered for 10 years… making this one of the best warranties in its price range. Other warranties include a lifetime for frames and 1 year for labor.


Just like its non ortho belt counterpart, this one is also overpriced. It provides little value for its very expensive price tag.


I don’t recommend the True 550 ZTX OP treadmill. There are other treadmills out there that would give you way better value for your money. Check out brands like Landice or Woodway. Also, visit our best buy treadmills section. You’ll find lots of comparable treadmills on that page.
