Treadmill Review

Last Updated: June 9, 2023

The newest budget high-quality treadmill that you should be considering if you are looking for an affordable treadmill for walking and jogging is the NordicTrack T 6.5 Si. As NordicTrack phases out the C series, the T 6.5 Si is a replacement for the NordicTrack C700 with some impressive upgrades.

A key upgrade found in the T 6.5 Si is the 10” touchscreen display. This high-definition screen is a definite upgrade from the simple LED windows on the C700. The T 6.5 Si also has a commercial 2.6 CHP* motor, which is a great motor size for walking and light jogging.

Also, this treadmill comes with a free month of access to the iFit training program, allowing you to not only have access to world-class running instruction but also a wide variety of cross-training programs.

If you are looking for an affordable treadmill to do your walking and some light jogging, we recommend the NordicTrack T 6.5 Si.

Pricing For The T 6.5 Si Varies

MSRP for the T 605 Si is $1299. But we regularly see this treadmill on sale for $900. That’s why we have categorized it with treadmills between $700 and $1000.

The T 6.5 Si Is Built For Users who:

  • Want a high-tech and affordable treadmill - The old adage, “You get what you pay for,” is definitely true when it comes to workout equipment. With the T 6.5 Si, you pay an affordable price and can enjoy the tech features that NordicTrack packs into all their treadmills.
  • Enjoy fitness technology - Users who love the latest fitness technology will love the T 6.5 Si. It comes with a smart touchscreen that will respond quickly to your touch, and you can easily navigate through a variety of personal trainer-designed workout programs.
  • Need treadmill programs with high engagement - Not only can you enjoy quality workout programs but you can access thousands of iFit workouts and run in exotic locations around the world as well as engage in a huge variety of cross-training.

The T 6.5 Si Is A Top Pick For Walking Treadmills

We compare treadmills first in their pricing category and then against all treadmills, regardless of price. It’s rare to see such an inexpensive treadmill score so highly. But we really do feel that if you’re planning on mostly walking on your home treadmill, the T 6.5 Si is one of the best treadmills you can buy.

  • Features and price balance - When looking at the T 6.5 Si, you can see that there is a clear balance between the pricing and what features are available, from the commercial motor to the incline range. In fact, when compared to other treadmills in its price range, this treadmill offers quite a bit more.
  • Available tech extras - As the engaging fitness tech NordicTrack has been incorporating into their workout equipment has improved, even their budget machines like the T 6.5 Si benefit, which means users like you can enjoy things like quality touchscreens and a free month of iFit without the price tag of the more expensive NordicTrack treadmills.
  • Some features potentially restrict user base - The treadmill belt length of the T 6.5 Si is 55”, which may make some users feel crowded. Also, it has a top speed of 10 MPH and lacks a fan. Lacking these things and other small limitations keep us from being able to rank the T 6.5 Si any higher.

Motor Size - The motor in the T 6.5 Si is a little smaller than the C700, measuring 2.6 CHP. However, it is also a commercial DurX motor, which makes it a stronger motor than you can find in the C700. Also, with its small size, the T 6.5 Si runs quietly as you workout.

*Please note that the 2.6 CHP motor comes from power achieved in a testing facility. Because of the limitations in residential homes and apartments, you will not be able to achieve the same power output on this treadmill as noted. We are not expert electricians but we are expert fitness equipment reviewers. This treadmill gives off plenty of power for light jogging and walking on a daily basis.

Running Area - Along with having a commercial tread belt, the T 6.5 Si has a running area of 20” wide and 55” long. This length may be a little short for users who are over 6’2” or have a longer stride in general.

Weight Capacity - User weight capacity for the T 6.5 Si tops out at 300 lbs, which is good compared to other budget treadmills in this price range.

Folding - A hydraulic system is built into the T 6.5 Si, allowing you to easily fold up this treadmill. Once it is raised up high enough, the T 6.5 Si deck will lock in place until you depress the lever. As the deck descends, you can allow it to touch down hands-free, as the hydraulic system will create a featherlight descent.

Space / Footprint - A compact treadmill, the T 6.5 Si measures 36” wide, 67.5” long, and 73” tall.

Max Speed - The maximum speed on the T 6.5 Si is 10 MPH, though we don’t recommend you use the upper speeds of this treadmill often, as it is not really built for heavy-duty running.

Incline - There is a decent incline range on the T 6.5 Si, going from 0% to 10%. That way, you can increase your calorie burn even while walking or lightly jogging.

Users can adjust the cushioning of the T 6.5 Si to suit their preferences. All that needs to be done is to turn the orange shock absorbers located directly along the sides of the T 6.5 Si to your preferred cushioning level. So, whether you want the top cushioning or want more resistance while working out, the T 6.5 Si will protect your joints from impact while allowing you to set your ideal cushion level.

Another point in favor of the T 6.5 Si is the commercial tread belt. With a commercial-grade belt, the durability of the belt is far greater than your average belt, and all you’ll need to do is potentially lube it up once a year to keep it in good condition.

The frame of the T 6.5 Si is relatively light, making it easy to fold up, tilt, and roll away if you need a treadmill you can put away when not in use. And with the lifetime frame and motor coverage, you can feel confident using the T 6.5 Si as long as you respect the weight limit of 300 lbs.

As for the return policy on the T 6.5 Si, you will have 30 days to try the T 6.5 Si in your home. If you find during that time that the T 6.5 Si isn’t for you or is defective, you can contact customer support for either a refund or a replacement. There is a 10% stocking fee applied to any refund unless the machine is defective.

Run along with trainers on beaches in Thailand or go on a walking tour in downtown London. All this and more are available on the T 6.5 Si thanks to iFit.

Display - An impressive, 10” high-definition touchscreen is built into the T 6.5 Si.

Speakers - Decent speakers are built into the T 6.5 Si, so you can workout headphone-free. The sound quality breaks up a bit at the highest levels, but it is unlikely that you will need to turn up the volume that loud, as the T 6.5 Si can output quite a bit of sound.

Fans - There is no fan built into the T 6.5 Si, making it the only NordicTrack treadmill without at least one.

Heart Rate Monitoring - On the T 6.5 Si, there are dual EKG handlebar pulse grips, which you can use for heart rate training. However, like all treadmill handlebar monitors, these are not very accurate and should be used only for rough measurements.

Bottom Line Review Of The NordicTrack T 6.5 Si Treadmill

While the T 6.5 Si is a good treadmill, it is a little limited in what it can offer. The length of the belt means it may not comfortably fit users over 6’-6’2”, as people around this height may find their stride restricted. Also, while the motor is a commercial-grade display, a treadmill with a 2.6 CHP motor should be primarily used for walking and jogging. However, there are a number of positives which set this budget treadmill above others in its price range:

  • Free month of iFit Coach access
  • 0-10% incline range
  • 300 lbs weight capacity
  • 10” HD touchscreen
  • FlexSelect cushioning

If you are looking for an affordable treadmill with quality features for your walking and light jogging workouts, then we recommend you consider the T 6.5 Si as your next treadmill.

Best Place To Buy The NordicTrack T 6.5 Si Treadmill

As the T-series treadmills are new to NordicTrack’s treadmill lineup, currently the only place to find them is on NordicTrack’s website. However, even if you were able to find them through a third-party, we generally recommend you go through NordicTrack to buy their treadmills.

That way, you can enjoy greater quality assurance, warranty coverage, and an easy return or exchange if you need it. Also, from our understanding, the free access to iFit will only apply to machines purchased through NordicTrack. The savings that will offer as well as the premier training programming available through the free access makes it even more attractive to buy the T 6.5 Si through NordicTrack.

Additionally, the NordicTrack T 6.5 S, not the Si, is the exact same treadmill with a downgraded display screen. This model treadmill is only available on Amazon and can save you around $300 if you’re looking for a less expensive treadmill. The display is downgraded to an LCD screen but the treadmill can still Bluetooth to your mobile device to access and view the iFit library.
