Specs Comparison

We know that pricing must be the top-concerned problem when it comes to purchasing (literally). In this battle, the T 6.5Si takes the lead since it is twice cheaper than the T 8.5s. To be specific, the T 8.5s costs more than $1,300, while the T 6.5Si’s price is between the $500 – $999 range.

That being said, let’s see how much weight these trainers can handle. Just like other Nordictrack trainers, they can carry a maximum of 300 pounds. There is no difference in user capacity between the cheap and the expensive one, unfortunately.

What about the number of built-in workout programs in each trainer? Well, there is a big gap between them. While T 8.5s has 50 programs, the T 6.5Si only offers 20 exercises for its users.

In terms of power, the T 8.5s is equipped with a powerful 3.5 CHP motor. Meanwhile, the T 6.5Si’ s engine only runs at 2.6 CHP, much weaker than the 8.5s.

Let’s discuss the treadmill’s incline range. In most of Nordictrack’s products, the incline and decline gap is always impressively wide. It’s the same case for these two. The T 6.5 Si’s incline range is about 0% to 10%. The figure for T 8.5s is a bit wider: 0-12%.

What about the product’s maximum speed? Well, the T 6.5Si allows users to reach 10 MPH, while the T 8.5s’ capacity is slightly higher: 12 MPH.

When the treadmills reach their highest speed, there may be so much heat released. The AutoBreeze system will cool down the T 8.5s’ engine. Meanwhile, there is no cooling fan capable of the T 6.5Si.

The heart monitoring feature is similar on both machines. Users just need to wear an EKG Grip Pulse, and the trainer will calculate the heart rate for you.

Sizing is another essential element to consider before purchasing. The T 6.5Si takes up space up to 36″ wide x 67.5″ long x 73″ high. On the contrary, the T 8.5s is less bulkier with 35.5″ wide x 78.9″ long x 59.4″ high. Additionally, they are foldable to reduce the space used.

You may wonder whether there are rollers to move the trainers? Well, they both have rollers. Based on the manual, the wheels are about 1.9″ Non-Flex, front and back.

What about the trainer’s belt size? Well, the NordicTrack T Series – 8.5s still overshadows its competitor with the 20″ X 60″ running surface. Meanwhile, the T 6.5Si only has the 20″ X 55″ belt. Therefore, the T 8.5s seems to be more suitable for taller people.

To activate, adjust the speed and incline range, just click the “Speed” and “Incline” buttons on the console for further change.

Features Comparison

As mentioned above, the console allows you to change the speed, the incline, and the decline angle for more comfortable training. According to the manual, they both contain a 10″ touchscreen. However, only the T 8.5s has a color display, while the T 6.5Si can only provide black-and-white images.

What about their speaker system? Well, just like other Nordictrack trainers, the T 6.5Si and T 8.5s are both equipped with dual 2″ digitally amplified speakers.

When there is a need to connect with other devices, you can use the built-in Bluetooth connecting gate in each trainer. However, there is no USB port or Internet connectivity in these two.

If you are wondering if it is possible to adjust the trainer’s construction or tilt up and back, then our answer is: Yes, you can. However, there is a big “Not available” for cooling fans for those who use T 6.5Si.

If you seek an application capable of these treadmills to keep track of your training, then the only choice for you is iFit. Once you buy these trainers, a premium iFit account will be assigned to you.

Additionally, the T 8.5s vs. T 6.5 Si are capable with Android and iOS devices. No need to worry about using different operating systems anymore, right?

Regarding the water bottle cubbies, both treadmills have a small built-in corner to place the drink. However, if you want a device holder, only the NordicTrack T Series – 6.5 SI has.
