Buying a used NordicTrack treadmill? Which model to pick (T series, Commercial 1750, X22i), what to inspect, common problems, and what to pay vs new.

A used NordicTrack treadmill on Commonplace has a median price of about $1,275 right now, and the middle half of the market sits between roughly $880 and $1,775. That spread is huge for one brand, and it's because "NordicTrack treadmill" covers everything from a $800 folding T 6.5 S to a $3,700 X32i incline trainer. The model you're looking at matters more than the condition, the year, or the photos.
I help people buy and sell big, heavy fitness equipment for a living, and NordicTrack decks come through our pickups more than almost any other brand. So I've seen which ones hold up, which parts die first, and which listings are priced like a different machine than the one in the basement. Below I'll cover which NordicTrack treadmill to look for, what to inspect before you pay, the problems that show up most, and what a used NordicTrack treadmill should cost against new.

Buy a Commercial 1750 if you run, an X22i if you walk on hills, and a T series only if you mostly walk and the price is low. That's the short version. NordicTrack sells four families of treadmill, and they're built for different people.
T series (T 6.5 S, T 6.5 Si, T 7.5 S and similar). These are the entry machines. The T 6.5 S runs a 2.6 CHP motor, a 20 by 55 inch belt, 0 to 10 mph, and a 10 percent max incline, with a 300 pound user capacity. It's been discontinued, so every one you find is used. It's a walking treadmill that can handle light jogging. If you're over six feet or you run real miles, 55 inches of belt will feel short fast.
EXP series (EXP 7i and relatives). A step up in screen and build, still in the folding home category. Good for walkers who want a touchscreen without paying Commercial prices.
Commercial series (1750, 2450, 2950). This is the running deck. The Commercial 1750 gives you a 22 by 60 inch belt, a 3 percent decline up to 15 percent incline, a 300 pound capacity, and a motor NordicTrack has rated between 3.5 and 4.25 CHP depending on the year. The 2450 sits above it with a bigger rotating screen and a 3.6 CHP motor. I wrote a full breakdown of which Commercial 1750 model years to chase, and a separate one on buying a used Commercial 2450.
X series incline trainers (X11i, X22i, X32i). These climb to a 40 percent incline. Nothing else in the home market does that. They're heavy, tall, and not really built for sprinting, but walking at 3 mph on a steep grade is a brutal workout. If that's you, read my guide to buying a used NordicTrack X22i.
Here's how I'd sort them.
| Family | Best for | Belt / incline | Typical used price |
|---|---|---|---|
| T series (T 6.5 S) | Walking, light jogging, tight budgets | 20 x 55 in, 0 to 10% | Around $800 |
| EXP series (EXP 7i) | Walkers who want a screen | Folding, incline training | $865 to $1,490 |
| Commercial 1750 | Runners, most households | 22 x 60 in, -3 to 15% | $909 to $1,781 |
| Commercial 2450 | Runners who want the big rotating screen | -3 to 15% | $700 to $1,300 private sale |
| X22i / X32i | Hill walkers, hikers in training | 22 x 60 in, -6 to 40% | $1,475 to $2,275 (X22i) |
The Commercial 1750 is the safest used NordicTrack treadmill you can buy. It's the one I'd send a friend to.

Run the incline through its full range first, because the incline motor is the most expensive common failure on a used NordicTrack treadmill. Everything else on this list is cheaper to fix. Here's the check I'd do in a seller's basement, in this order:
Do that and you'll know more about the machine than the person selling it. Most sellers have never taken their treadmill past 8 percent incline in their lives.

The frame almost never fails. The parts that do are the incline motor, the console, and the belt and deck, in roughly that order of cost.
Belts and decks are consumables. A treadmill with a few thousand miles on it needs one eventually, and that's normal maintenance, not a reason to walk. Incline motors are different. They do a lot of work on these machines, especially the X series, where the motor lifts the whole deck through a 46 point range instead of 15. When an incline motor goes, the deck sticks or the console throws an error and refuses to move.
Consoles are the other big one. The touchscreen is the part that decides whether the machine still feels current in a few years, and it's the part least likely to have a cheap fix. But here's the thing people miss: a NordicTrack treadmill with a tired screen still runs in manual mode. Speed, incline, time, distance. That's what a treadmill did for forty years before anyone bolted a tablet to one.
Walk away if you see any of these:
No. A used NordicTrack treadmill runs fine without iFIT, but you lose the trainer-led workouts and the automatic speed and incline control. That's the honest trade.
iFIT is attached to a person, not the machine. When you buy used, you don't inherit the seller's membership, and you'll need your own account if you want the content. iFIT pricing changes, so check the current number the week you buy instead of trusting any article, including this one. Ask the seller to log out of their account and factory reset the console before pickup. It saves you a headache on day one.
And if you only want to walk while you watch something on your own tablet, manual mode is all you need. So don't let the subscription question scare you off a good machine.
Expect to pay about 40 to 70 percent of the new price for a used NordicTrack treadmill in good working order. The exact number depends almost entirely on the model family.
Across NordicTrack treadmill listings on Commonplace, the median is about $1,275, with the middle of the market running from about $880 to $1,775. Those prices include a driver picking the machine up, inspecting it, and bringing it to your door, so they'll run higher than a cash pickup from a stranger's garage. Compare like for like.
By model, here's what I see. A Commercial 1750 lands between about $909 and $1,781 on our platform, against the $1,900 to $3,100 sellers tell us they paid new. A modern-generation Commercial 2450 trades around $700 to $1,300 in a private sale, against a new price near $2,499. An X22i sits between $1,475 and $2,275, and sellers report paying $3,000 to $5,000 new. A T 6.5 S usually shows up around $800.
The sweet spot is a two to four year old Commercial 1750. You get the 22 by 60 deck, the decline, and a modern screen at roughly half of new. Once a used one is within a couple hundred dollars of a discounted new one, buy new and take the warranty.
One more thing on price. A 2018 Commercial 1750 and a 2023 Commercial 1750 share a name and almost nothing else, so always check the sticker before you compare prices across listings.
Plan the move before you agree on a price, because a Commercial 1750 weighs over 300 pounds and an X22i weighs over 400. That's the part that turns a great deal into a bad weekend.
The folding Commercial and T series models are manageable with two strong people and a stair dolly, deck up and weight centered. The X series doesn't fold the same way and usually has to come partly apart. I wrote a step-by-step on how to disassemble a NordicTrack treadmill for moving if you're doing it yourself. Basements with a turn at the bottom of the stairs are where these get scratched, dropped, and abandoned halfway.

Or skip all of it. When you buy through Commonplace, our driver picks the treadmill up, runs the inspection on site, and delivers it to your door. You don't meet a stranger, you don't rent a truck, and you get a 60-day warranty on the machine. One seller who'd sold a Peloton Tread+ with us said they knew they couldn't deal with Facebook Marketplace and potential scammers. That's the whole reason most people use us for something this heavy.
Yes, if it's a Commercial or X series that passes the incline and belt checks. The frames last a long time, and you save roughly half of new. A worn T series at a high price is the one to skip.
The frame and motor usually outlast the screen. Belts and decks wear with miles and get replaced as maintenance. The console is the part that ages fastest, and it's the part that most often decides when an owner moves on.
Around $1,275 is the middle of the market on Commonplace, with most landing between about $880 and $1,775. A late-model X32i can go well above that. An older T series can go well below.
The Commercial 1750. It has the 22 by 60 inch belt, decline, and a motor that handles daily miles. The T series is too short for real running if you're tall.
Absolutely. Manual mode gives you speed and incline control with no subscription. You only lose the guided workouts and automatic adjustments.
