The NordicTrack T 6.5 S is a folding home treadmill for walking, jogging and running up to 10 MPH, with a 0–10% incline range and optional iFIT workouts. Its 55 x 20 inch deck and assisted folding frame are useful home features, but the machine still needs a substantial footprint and weighs 203 lb.
This NordicTrack treadmill T6.5S makes the most sense if you want incline workouts and plan to use either the LCD stats or a connected phone or tablet. If you mainly want a simple walking machine, compare its size and features with the alternatives before committing to a spot.
What does the NordicTrack T 6.5 S offer?
The T 6.5 S pairs 10 MPH speed, 10% incline and a 5-inch LCD in a foldable frame. That combination covers steady walking through faster home runs, while iFIT adds guided workouts for users who want them.

NordicTrack says the deck uses KeyFlex cushioning to reduce joint impact. That is the brand's description of the feature, not a guarantee that it will feel right for every runner.
Who should consider this NordicTrack T6 5S treadmill?
Consider it if you want a home treadmill with adjustable incline, a 55-inch deck and the option to follow trainer workouts from your own device. The frame folds and has assisted lowering, which can make storing it more manageable after a session.
Think carefully if you need to move the treadmill often. At 203 lb, it is a heavy machine, and its folded length is still 78.5 inches.
What are the T 6.5 S dimensions and key specs?
The T 6.5 S needs room for a 73.5 x 36 inch footprint while open, plus safe clearance around it. Measure the use area and the route into your home before delivery.

A folding deck helps reduce the upright storage height, but folding does not make the treadmill small. Check the folded length against your wall, closet or storage area.
The box should fit through the delivery route before the treadmill reaches its final spot. Measure doorways and turns, and plan where the machine can remain during setup.
Is the T 6.5 S a good fit for running?
The 10 MPH maximum speed and 55 x 20 inch deck give the T 6.5 S a stated range for walking, jogging and running. People with a longer stride should pay particular attention to the deck length and test a similar size when possible.
A 20-inch width offers room for normal foot placement, but your running form and pace matter. If you prefer wide lateral movement or train at high speeds, compare deck measurements across models rather than relying on broad labels like “home treadmill.”
KeyFlex cushioning is intended to soften impact, according to NordicTrack. Cushion feel is personal, so it’s useful to try the treadmill in person if joint comfort is a major factor in your choice.

What does iFIT add, and is the membership necessary?
The T 6.5 S can show live workout stats on its LCD without iFIT, while guided training and automatic adjustments require an iFIT Train membership. You can use your own phone or tablet to follow trainers and connect to the workout experience.
NordicTrack lists access to more than 10,000 workouts with membership, along with SmartAdjust and app syncing. ActivePulse also requires a compatible Bluetooth heart-rate monitor, sold separately, and a membership.
If you prefer a screen built into the treadmill, compare models in our guide to the best NordicTrack treadmill with screen. For a broader look at connected options, see our guide to best iFIT treadmills for home.
How does the T 6.5 S compare with the NordicTrack T 5 S?
The T 6.5 S is the better match if you specifically want its 10% incline, 10 MPH speed and 55 x 20 inch deck. Compare the detailed specs for each exact model and check which features matter for your workouts.
Our NordicTrack T 5 S review looks at another option in the same family. If you're still deciding between brands, our NordicTrack vs ProForm treadmill comparison can help narrow the choice by workout style and features.
What are the main trade-offs?
The T 6.5 S's main strengths are its incline range, foldable frame and optional connected workouts. Its trade-offs are the large open footprint, heavy frame and membership requirement for iFIT training features.
The 0–10% incline can add uphill effort to walking or running sessions. If you want a steeper maximum incline, compare an alternative such as the Sunny Health & Fitness Fully Assembled Auto, which lists up to 15% auto incline and 24 preset workout programs.
The Sunny model is listed as fully assembled and offers a 20 x 53 inch running surface. Its SunnyFit app includes trainer-led videos and virtual tours, so it suits a buyer who prefers that app ecosystem.
A home treadmill also needs routine care. Keep the surrounding area clear, follow the owner's manual for cleaning and lubrication, and stop using the machine if a belt or electrical issue appears.
Can you replace the T 6.5 S walking belt?
A compatible replacement belt is available for T 6.5 S model numbers 250160 and 263241. Confirm the exact number on your treadmill before ordering because compatibility can depend on the specific model.
SHEJIO describes the belt as PVC with anti-static conductive wires and says it is pre-lubricated. Its care guidance recommends lubricating at least once a year, but follow the treadmill manual and belt instructions for the correct product and amount.
Too much lubricant can cause belt slip, according to the belt's instructions. If you're unsure about installation or fit, contact the belt seller or a qualified service provider before removing parts.
Is the NordicTrack T 6.5 S worth choosing?
The NordicTrack T 6.5 S is worth considering if you want a folding treadmill with 10 MPH speed, a 10% incline and optional iFIT training. Check the dimensions, weight and membership needs against how and where you plan to use it.
Choose it for guided workouts and incline variety in a home setup with enough space. Pick a different model if you need a steeper incline, a lighter machine or a different connected fitness system.
