As a NASM-Certified Personal Trainer, I get asked about the NordicTrack T6.5 S more than almost any other budget treadmill — it’s one of Amazon’s best-sellers, and it’s a regular fixture on “best treadmill under $800” lists. But the five-star reviews rarely mention the one thing that comes up in longer-term owner feedback: it gets loud at higher speeds.
For this review, I went through the spec sheet, NordicTrack’s own claims, and the recurring themes in owner discussions across retailer and forum reviews to answer the question my clients actually ask: not “is it good,” but “is it good for me?” Where I reference specific owner experiences below, they’re patterns pulled from Amazon customer reviews and treadmill owner forums — not a formal survey, but consistent enough across sources to be worth noting.

NordicTrack T 6.5 S Treadmill Review: Quick Verdict
Buy the NordicTrack T6.5 S if:
- You’re walking, doing light cardio, or jogging a few times a week
- You want smart-training features available even if you don’t use them right away
- You can live with some motor noise at higher speeds
Skip it if:
- You need a quiet treadmill (thin walls, sleeping baby, apartment living)
- You’re training seriously for speed and distance running

Who the T 6.5 S Is Actually Built For
This isn’t a treadmill built for marathon training, and NordicTrack doesn’t market it that way. It’s designed for walking, light cardio, and jogging — the kind of consistent, moderate-intensity movement that actually drives most people’s fitness and weight-loss results.
It uses NordicTrack’s FlexSelect cushioning, engineered to reduce joint impact and smooth out each stride over time. From a trainer’s perspective, this matters more than people expect: joint-friendly cushioning is often the difference between someone sticking with a walking or jogging habit for years, versus quitting after a few sore weeks. One long-term owner reported walking 6–9 miles a day on this machine for years without issues — a strong track record for a treadmill in this price bracket.
Smart Features: What iFIT Actually Gives You
The T6.5 S leans heavily into NordicTrack’s iFIT ecosystem. With an active membership, you get:
- 10,000+ guided workouts led by real trainers
- ActivePulse — reads your heart rate via a Bluetooth monitor and automatically adjusts speed/incline to keep you in your target zone
- SmartAdjust — scales workouts based on your training history over time
- App syncing with Strava, Garmin, and Apple Health
- AI Coach — text-based coaching for workout plans
That’s a genuinely strong feature set for this price point — but only if you’re using the subscription.
The Catch: You’ll Need an iFIT Membership
Here’s the part that trips a lot of buyers up: almost everything listed above requires a separate, ongoing iFIT Train membership. Some owners have pointed out that the treadmill feels built around the subscription rather than optimized to work great without it.
The good news: you can use the T6.5 S manually, at zero subscription cost. You’ll lose ActivePulse, SmartAdjust, the AI coach, and the guided workout library — but you’ll still have a fully functional treadmill with a solid motor and real cushioning underneath.
My honest take as a trainer: if you’re self-motivated and know how to structure your own walk/jog intervals, skip the subscription and save the money. If you do better with guided structure and accountability, factor the iFIT cost into your total cost of ownership before you buy — it changes the math.
The Noise Issue (Read This Before You Buy)
This is the one thing almost no five-star review leads with: multiple long-term owners consistently flag this treadmill as noticeably loud at higher speeds, with some reports of frame bounce during use.
If you live in an apartment, have thin walls, or have someone sleeping nearby during your workout window, this is worth knowing before you buy — not after it’s sitting in your living room.

NordicTrack T6.5 S vs. the Competition
If you’re weighing this against other options in the same price range, here’s how it stacks up:
| NordicTrack T6.5 S Check Price → | Sole F63 Check Price → | Horizon 7.0 AT Check Price → | |
|---|---|---|---|
| Best For | Walking, light jogging | Regular running | Regular running, app flexibility |
| Motor | 2.6 CHP | 3.0 CHP | 3.0 CHP |
| Deck Size | 20″ x 55″ | 20″ x 60″ | 20″ x 60″ |
| Shock Absorption | Good (FlexSelect) | Better, built for running impact | Good |
| Warranty | 10-yr frame / 2-yr parts / 1-yr labor | Lifetime frame & motor | Lifetime frame & motor, 3-yr parts |
| Programming | iFIT (own device) | Sole+ app (own device) | Bluetooth to Zwift, Peloton, Nike Run Club |
| Subscription Required for Full Features | Yes (iFIT) | No | No |
A quick note on that deck-size gap: the shorter 55″ deck isn’t NordicTrack cutting corners relative to what $799 typically buys — trimming the deck a few inches is one of the standard ways budget treadmills hit a lower price point in this category. The Horizon 7.0 AT shows you can get a 60″ deck for $200 more, and the Sole F63’s 60″ deck comes at $200-300 more.
Bottom line: if your budget is tighter and you’re mainly walking or doing light jogging, the T6.5 S is the better value. If joint impact from actual running is your main concern, the Horizon 7.0 AT gets you a longer deck and stronger warranty for about $200 more ($999 vs. $799). The Sole F63 costs $300 more ($1,099 vs. $799) and is built for serious running — worth it if that’s your goal, overkill if it isn’t.
Ordering and Setup: What to Expect
A few practical things worth knowing before it shows up at your door:
- Assembly time: Budget at least two hours, and it’s easier with a second pair of hands — reviewers consistently note this isn’t a solo 20-minute job. A professional assembly add-on (roughly $100 on Amazon) is available if you’d rather skip it.
- iFIT account setup: Out of the box, the console prompts you to create an iFIT account — including entering payment info — before the treadmill will run, even though the first 30 days are free. Some owner forum threads mention ways to skip past this prompt into manual mode, but the specifics vary by post, and I haven’t tested any of them myself, so I won’t print steps I can’t stand behind. If skipping the subscription flow matters to you, it’s worth a quick search of current owner forums before you unbox it, since methods can also change with firmware updates.
- Returns: Standard Amazon return policy applies (typically 30 days for unused, unopened items) — check the listing at the time of purchase, since return windows can vary by seller.
Pros and Cons: NordicTrack T 6.5 S Treadmill
Frequently Asked Questions
Is the NordicTrack T 6.5 S good for running?
It’s best suited for walking and jogging rather than sustained or serious running. If running is your primary goal, a machine with a stronger motor and running-specific shock absorption, like the Sole F63, is a better fit.
Do you need an iFIT membership for the NordicTrack T 6.5 S?
No — you can use it manually with no subscription. However, you’ll lose access to ActivePulse, SmartAdjust, the AI coach, and the guided workout library, which are the treadmill’s main smart features.
Is the NordicTrack T6.5 S loud?
Yes, multiple long-term owners report it gets noticeably loud at higher speeds, with some frame bounce. Worth considering if you live in an apartment or exercise near sleeping family members.
What’s the NordicTrack T 6.5 S weight capacity?
It’s rated for users up to 300 lbs.
Is the NordicTrack T 6.5 S worth it in 2026?
For its core use case — walking, light cardio, and jogging — yes. It remains one of the best value options in its price bracket, provided you go in aware of the noise level and the subscription-dependent feature set.
Final Verdict: One of the Strongest Picks in This Price Range
| Category | Score | Why |
|---|---|---|
| Build Quality / Durability | 4/5 | Solid frame for the price; some owner reports of frame bounce at higher speeds |
| Speed & Incline Range | 3.5/5 | Meets the standard “above-average” bar (10 mph, 10% incline) but doesn’t exceed it, unlike pricier competitors at 12–15% incline |
| Programming & Tech (iFIT) | 4.5/5 | ActivePulse, SmartAdjust, and the workout library are strong for $799 |
| Ergonomics (Cushioning + Deck) | 4/5 | FlexSelect cushioning is a genuine standout; the 55″ deck is shorter than competitors’, standard for this price tier |
| Footprint & Portability | 4.5/5 | Compact folded footprint, EasyLift Assist hydraulics praised consistently across owner and reviewer feedback |
| Value | 4/5 | $300 cheaper than the Sole F63, only ~$200 more than skipping to the Horizon 7.0 AT; tempered slightly by subscription-dependent features |
| Noise Level | 3/5 | The most consistent complaint in owner feedback |
| Warranty | 4/5 | 10-year frame warranty is generous for this tier; 2-year parts and 1-year labor are solid but not exceptional |
Overall: ~3.9/5
The pattern across categories tells its own story: this treadmill scores well everywhere tied to daily use — build, cushioning, features, portability — and only drops below average on the two things tied to pushing it past its intended purpose (Speed & Incline Range) and to shared-wall living (Noise). That’s a pretty clean signal that the T6.5 S rewards buying it for what it’s designed for, rather than stretching it toward serious running.
