Treadmill Review

Updated: 8-20-2019

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.

Some of the key changes that the T 6.5 Si comes with that raises above your average budget treadmill are things like the 10” touchscreen which acts as a console. 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, giving it greater durability and power than can usually be found in a treadmill in this price range.

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

So, if you are looking for an affordable treadmill to do your walking and some light jogging, then you should consider the NordicTrack T 6.5 Si.


The pricing on the T 6.5 Si generally is between $799-$899, though it can go over this price. We recommend you wait to buy if it is priced above $899 until it is back in this range.

The T 6.5 Si Is Built For Users who:

  • Want a high-quality 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 high-quality 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 Coach workouts and run in exotic locations around the world as well as engage in a huge variety of cross training.

Why The T 6.5 Si earned 3.8 out of 5 stars

Before you think that’s a bad score, here at Treadmill Reviews, it is not often that a budget treadmill scores this high. Some of the key areas we focused on were:

  • 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 free iFit Coach 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.

Overall, the NordicTrack T 6.5 Si is a good treadmill and will be perfect for a household looking to walk or jog but not do any serious running.

Main Specs - 7/10

Specs “Quick Review”:
  • Motor Size: 2.6 CHP
  • Running Area: 20” W x 55” L
  • Weight Capacity: 300 lbs
  • Folding: Yes
  • Footprint In Use (W, L, H): 36” x 67.5” x 73”
  • Incline Range: 0% to 10%

  • Electrical Requirements: 120V

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.

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 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 max 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.

Features - 8/10

Features “Quick Review”
  • Display: 10” touchscreen
  • PreInstalled Workout Apps: 20
  • Speakers: Yes
  • Fans: No
  • Heart Rate Monitoring: EKG Grip Pulse
  • USB port: No
  • Audio Jack: Yes
  • Water bottle cubbies: Yes
  • Device holder: Yes

Workout Apps - There are 20 built-in workout programs on the T 6.5 Si, ranging from calorie burn to distance. Along with the programs which come with this treadmill, you also have access to iFit Coach.

If you haven’t heard of iFit Coach, it is a training program that gives you access to thousands of on-demand workout programs led by world-class personal trainers. 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 Coach.

Display - An impressive, 10” high-definition touchscreen is built into the T 6.5 Si. With the design of the console keeping it stable, the touchscreen can be your doorway into some of the best workouts when using iFit Coach, all in vibrant color and in-depth workout information available all at the touch of your finger.

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.

Other Tech Features
  • iFit Coach year membership
  • Shelf for devices to be placed
  • Emergency stop key

Build Quality - 8/10

T 6.5 Si Review: Build Quality
  • Warranties - Lifetime frame and motor, 1-year parts and labor
  • Belt - Commercial Tread Belt
  • Roller Size - 1.9” Non-Flex rollers
  • Cushioning - FlexSelect cushioning
  • Customer Support - Email, live chat, phone
  • Return Policy - 30-day trial

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 the 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.

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 work for those who are over 6’-6’2”, as people around this height may find their stride restricted. Also, while the motor is a commercial-grade one, a treadmill with a 2.6 CHP motor should be primarily used for walking and some jogging. However, there are a number of positives which set this budget treadmill above others in its price range:

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

So, if you are looking for an affordable treadmill with quality features for your walking and light jogging workouts, then we do recommend you consider the T 6.5 Si as your next treadmill. If you need a more powerful treadmill and a step up in features, we recommend you check out other NordicTrack treadmills, which have many of the engaging features of the T 6.5 Si with even better build qualities and other features.

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 Coach 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.
