NordicTrack T 6.5 Si Review 2021

          Our Rating: 4.5/5


The cheapest of NordicTrack’s treadmill lineup, the T 6.5 Si is a technological wonder in the world of treadmills. Providing features owners of other brands of treadmills can only dream of, this model is still relatively expensive in comparison to the economical choices of other brands.

That being said, innovation isn’t cheap; if the cutting-edge of tech is what you’re looking for, look no further. A great option for walkers or light joggers, you’ll discover all there is to know about the T 6.5 Si in the below review.


Build Quality

If you’re interested in breaking into the world of technologically advanced treadmills, NordicTrack is a long-standing and popular brand that should be strongly considered.

The brand’s forward thinking conception of how exercise should look and feel is made whole in the way they thoughtfully craft their products to provide guidance to ensure you are making the most of your exercise journey. While this guidance is mainly offered through their iFit program that comes as an additional subscription model, the build of their high-quality treadmills is reflected in the high end parts they use.

The NordicTrack T 6.5 Si Treadmill is the cheapest NordicTrack option that will seamlessly grant you access into their diverse world of high-tech possibilities without the hefty price tag that comes with their higher end models, making it the most feasible option should you feel a bit intimidated when comparing NordicTrack to traditional treadmills.

Protecting the body you desire to strengthen is key when selecting a treadmill and the T 6.5 Si meets the challenge with its FlexSelect Cushioning design. Kicking off the technologically advanced leg up NordicTrack has on its competition is cushioning which can be altered to your preference, whether you prefer it on, off, or even if you are being mindful of an injury for a period of time. The FlexSelect Cushioning dampers far outweigh the standard cushioned deck many traditional treadmills provide as they can be altered, which helps to emulate outdoor workouts, making your target muscle groups more prominent.

Furthering its mindful build is the SMART-Response Drive System which ensures your treadmill experience has as little vibration as possible for smooth performance. Enjoy worry free exercise as this system self-regulates by automatically cooling should the motor get heated from your hard work.

The 20” x 55” walking belt is commercial grade and has been coated with high performance lubricant to promote lasting function. The DurX Commercial Plus motor is specifically unique to NordicTrack treadmills.

The T 6.5 Si offers an average 2.6 CHP in motor strength, making it ideal for those interested in walking, speed walking or light jogging. Should you hope to pursue running yet would like to stay within the NordicTrack family, we’d recommend the T 8.5 Si (3.5 CHP) or T 9.5 S (3.6 CHP) models, both of which come with more power and higher speed capability, features which unfortunately cost hundreds more.

Despite lower horsepower, the T 6.5 Si still offers a range of 0-10 MPH as well as a 10% incline so you can still feel the burn. Many squander the idea of having a treadmill in their space due to the eye sore it can create, however, the T 6.5 Si is thoughtfully created to fit your home, rather than make your home fit it, as has been created with the NordicTrack SpaceSaver Design with EasyLift Assist. This simple folding mechanism was made to allow the deck to fold up completely.

Should you need to move it, the T 6.5 Si makes it effortless with the two wheels placed towards the front of the treadmill so anyone of any strength is capable of moving it. If you are looking to enter into the world of fitness, the NordicTrack T 6.5 Si is the T Series model that will be a wonderful fit to partner alongside you!



Technology is where NordicTrack outshines the competition each and every time, as they’re known for their innovative build process of futuristic features. A beauty to behold, the Smart HD Touchscreen on the T 6.5 treadmill is 10”. While the T 6.5 is the first of the T Series, it still outweighs competitors such as Sole and Horizon as none of their screens offer touch technology.

To put into perspective, even the highest end models such as the Sole TT8 or the Horizon 7.8 AT only offer TFT screens and will cost you significantly more. These competitors also rely on you having a personal tablet to place on the treadmill should you hope to stream workouts, making even the budget-friendly NordicTrack T 6.5 Si a cake walk when compared to other technological offerings.

The Smart HD 10” screen comes preloaded with 20 readily accessible work-out programs. These standard offerings also put the Sole and Horizon brands to shame as they offer a meager range of which; Sole’s top unit offers 9 programs while Horizon’s offers 11.

If that’s not enough, you’ll also receive 1-year of free access to NordicTrack’s insanely well-designed iFit program with purchase, which gains you access to Live Streaming workouts with elite Trainers. These trainers provide incredible motivation, detailed guidance and, the coolest part: They control your speed and incline automatically so you’re not left trying to keep up. All you have to do is show up in the comfort of your own home to have a personalized, in-class experience.

The T 6.5 Si iFit program recommends new classes to you daily, busting fitness boredom like it’s nothing. Each iFit membership, of which the T 6.5 Si comes with free for a year, allows you to have 4 profiles so multiple family members can reap the benefits of live classes and track their workout progress via their profile throughout their health journey.

Making wellness even more well-rounded is the option to also get nutrition, activity and sleep coaching to ensure you are well on your way to your best self. The dual 2” digitally amplified speakers will help you keep up your energy while the auxiliary music port allows you to pump your own tunes.

When it comes to tech advancements, you can rest easy knowing the NordicTrack T 6.5 Si has you covered with it’s impressive and advanced characteristics that even the tech-buff in your family can enjoy without critique.


Price Point

Ladies and gents, we offer up the first caveat when considering NordicTrack: price. The NordicTrack T 6.5 Si offers a 2.6 continuous horsepower motor, which could be better when considering the price point is over $1,000.

For comparison, the Sole F63 Treadmill will save you a couple hundred dollars while offering a 3.0 HP motor with a range of up to 12 mph versus the NordicTrack T 6.5 Si range up to 10 mph. However, it’s easy to see why those couple hundred dollars matter when it comes to technology as Sole treadmills are incredibly outdated. They perform well and are built tough as is the case with the NordicTrack T6.5 Si, but they lack the number workout programs, live classes altogether, touchscreen ability and more intricate speaker quality.

With the trusted and well-loved NordicTrack brand, you are paying for quality build and advanced technology. Contrasting the T 6.5 Si to other treadmills in the same NordicTrack T Series is a piece of pie when it comes to pricing as the T 6.5 Si is the most economically friendly option NordicTrack provides.

Should you want to upgrade to bluetooth audio capabilities, a 3.5 CHP DurX Commercial Plus Motor, speed range up to 12 mph and 12% incline, all of which which we recommend for joggers or runners, the T 8.5 S is the next up to bat. The T 8.5 S will of course set you back more money, however, we recommend it for workout buffs.

When considering the technological bells and whistles that come with the NordicTrack brand, price is certainly justified as it pertains to the T 6.5 Si treadmill.


Pros and Cons

As noted in the price point section above, the easiest con to see regarding the T 6.5 Si is the lower motor power of 2.6 CHP. If you are an avid runner but still on a budget, we recommend upgrading to the NordicTrack T 8.5 to get a more powerful 3.5 CHP motor, a larger speed range up to 12 mph and an increased 12% incline.

If you prefer to not pay for advanced technology but want to opt for power, we advise you look into Sole or Horizon Fitness brands. An area of improvement when considering competing Sole and Horizon Fitness is the warranty coverage they each offer, as NordicTrack provides less across the board, which is detailed in the warranty section below.

Another ding to note on the T 6.5 Si is its lack of bluetooth capability. However, the auxiliary music port can be used to hook up your device of preference so you can still utilize the crisp 2” speakers.

While the touchscreen streams outrageously incredible live fitness classes with the iFit membership, this subscription-based service is a pricey fee once the complimentary 1-year trial is up.

Now that we’ve got the grit out, let’s focus on the bread and butter. The NordicTrack T 6.5 Si is equipped with 1.9” Precision and Balanced Non-Flex Rollers and a SMART-Response Drive System, which make for a dependably smooth and quiet ride. Its specialized deck folding capability and wheels make the T 6.5 Si easier to move about the cabin than when in flight on an airplane.

An admirable feature we love that promotes personalization is the FlexSelect Cushioning, which you can turn on or off, making an indoor workout feel like the great outdoors. Furthermore, the beautiful 10” Smart HD touchscreen allows you to feel as if you are working out in the space you are viewing by way of the vast library of 20 pre-loaded workout programs.

The EKG Grip Pulse will give you a detailed read of your body’s activity while the iFit program allows you to track and store progress achieved through the years. The NordicTrack T 6.5 Si certainly has more pros than cons when it comes to users who want to walk or run at speeds up to 10 mph with a 10% incline.

Warranty and Guarantee

The NordicTrack brand is known for creating quality treadmills you can trust, which is why they are one of the most popular brands in the fitness game. They change and advance their treadmills as new technology unfolds, unlike Sole and Horizon Fitness.

Unfortunately, where NordicTrack has space to grow is their warranty coverage. With the T 6.5 Si, you get a 10-year frame warranty, 2-year parts warranty and 1-year labor warranty with purchase. In comparison, the Horizon and Sole offer lifetime warranties on their frames and motors.

Should you want to invest in an extended service plan, NordicTrack offers this option for the T 6.5 Si, providing deeper peace of mind through a lifetime of ongoing use. While it’s great that NordicTrack offers warranty coverage, it certainly could be better without having to pay an additional cost.


Summing Up This Review
