NordicTrack Commercial 2450 Review

Every NordicTrack shopper eventually runs into the same question: is the Commercial 1750 enough, or do you need to spend more? The Commercial 2450 is NordicTrack's answer for the specific runner who outgrows the 1750, and after four weeks testing the two side by side, we have a clear picture of exactly who that upgrade makes sense for — and who it doesn't.

Overview and Who It's For

The Commercial 2450 occupies the middle of NordicTrack's Commercial line, sitting above theCommercial 1750and below the flagshipCommercial 2950. It's built specifically for the buyer who has already decided the 1750's fundamentals are right — the deck, the frame, the general shape of the machine — but wants a stronger motor and a steeper incline ceiling for genuinely demanding training.

We structured this review as a direct comparison against the 1750, since that's the real decision most shoppers reading this page are facing. Our conclusion after weeks of alternating between the two: the difference is real and noticeable specifically during hard incline work and sustained runs above 8 mph. During moderate walking or easy jogging, the two machines feel close enough that the extra $500 is genuinely hard to justify on performance grounds alone.

This is still a folding treadmill using the same SpaceSaver design as the rest of the Commercial line, with a slightly larger folded footprint than the 1750 due to the bigger 24-inch touchscreen mast. It's built for a dedicated home gym space rather than an apartment that needs the treadmill to disappear daily, the same positioning as its siblings.

We'd recommend the Commercial 2450 most strongly to a runner training for a race that involves elevation, someone doing structured hill-repeat workouts regularly, or anyone who's previously felt a smaller motor working audibly harder during push-pace intervals and wants that feeling gone entirely. If none of that describes your training, read ourCommercial 1750 reviewof the step-down model before committing to the extra spend here.

It's worth being specific about what "outgrowing the 1750" looks like in practice, since that phrase gets thrown around loosely. In our testing, the 1750's motor never failed outright or overheated — it simply worked audibly harder, with a faint but noticeable change in motor pitch, during back-to-back incline intervals at 12% and above. That's not a defect on the 1750; it's a machine operating near the top of its intended range rather than in the middle of it. The 2450 exists precisely to move that workload back into the middle of the motor's comfortable range, which matters if you're doing that kind of training multiple times a week rather than as an occasional challenge.

Full Spec Sheet

Here's every spec we verified directly against our test unit rather than copying from the manufacturer's marketing page.

Assembly and Setup

Assembly took roughly 80 minutes with two people, close to the 1750's build time but a bit longer thanks to the larger 24-inch touchscreen mast, which the manual recommends two people lift into place. The console arrives mostly pre-wired, and the included tools covered the entire build without needing to supplement from our own toolbox.

The shipping crate is noticeably heavier than the 1750's, closer to 250 pounds, so plan your delivery location accordingly — this isn't a machine you want to carry up a flight of stairs in its original box. Once assembled, we ran through our standard calibration check: full incline and decline range, safety key test, and a firmware check on the touchscreen before the first real workout.

Performance Deep Dive

Motor and Deck: Where the Upgrade Actually Shows Up

This is the section that matters most for anyone deciding between the 2450 and the 1750. During moderate walking and easy jogging up to about 6 mph, the two motors feel nearly identical — both handle that workload without any strain, and most testers couldn't tell which machine they were on blindfolded. The difference shows up clearly once you push past 8 mph or add sustained incline: the 2450's 4.25 CHP motor held belt speed rock-steady during a session combining 8.5 mph running with repeated climbs to 12% incline, while the 1750 under the identical protocol showed very slight, barely perceptible belt speed variation during the steepest climbs. It's a small difference in absolute terms, but it's the kind of thing a runner training seriously will notice over weeks of repeated hard sessions, even if a casual user never would.

The 22 x 60-inch deck is identical to the 1750's, so the upgrade here is entirely about motor strength and incline ceiling, not running surface. Both machines comfortably fit our 6'3" tester at full stride.

Incline, Decline, and Hill Training

The 2450's 15% max incline versus the 1750's 12% is the single biggest functional difference between the two machines, and it's the reason we'd recommend the 2450 to anyone doing dedicated hill training. During a structured hill-repeat session — alternating between flat recovery jogging and 12-15% incline climbs — the steeper ceiling let us simulate genuinely demanding terrain that simply isn't available on the 1750. Decline is shared at -3% between both models, useful for downhill-specific training or simply varying the stimulus during long iFit trail runs.

The 24-Inch Touchscreen

The step up from the 1750's 14-inch screen to a 24-inch display is noticeable immediately, closer in spirit to a small television than a large tablet. iFit's trainer-led trail runs feel more immersive on the larger screen, and we found ourselves more likely to choose a scenic guided run over a manual session simply because the visual experience was more compelling. It's a smaller jump than the 2950's 32-inch screen, but it's the point on the NordicTrack lineup where screen size starts to feel like a genuine amenity rather than a marketing footnote.

Cushioning, Console, and Everyday Usability

FlexSelect cushioning works identically to the 1750, with the same three firmness settings via a lever under the deck. Testers with knee sensitivity again preferred the softest setting for daily walking, while faster interval sessions felt more responsive on the firmest setting. The built-in speakers and Bluetooth pairing performed the same as on the 1750 — reliable, adequate volume for a small room, nothing to complain about but nothing exceptional either.

Folding and Footprint

The EasyLift assist strut helps the same way it does across the Commercial line, though the larger touchscreen mast makes the 2450 feel marginally heavier to fold than the 1750. Standing folded, its 37 x 83-inch footprint is only slightly larger than the 1750's, so if folding for storage matters to you, the difference between these two specific models won't be the deciding factor.

Noise, Vibration, and Household Fit

Despite the stronger motor, noise levels stayed close to the 1750's — low-60 decibels during sustained running, comparable to normal conversation. We expected the bigger motor to run louder under heavy load, but NordicTrack's motor housing insulation appears to have been tuned for this specific model, and the difference was negligible even during hard incline intervals. Vibration transfer through the floor was also comparable to the 1750, so if noise or vibration were a concern with the smaller model, upgrading to the 2450 won't meaningfully change that calculus one way or the other — a mat underneath still helps on hard flooring regardless of which model you choose.

Real-World Training Scenarios

We ran the 2450 through three training scenarios we think map closely to how serious home runners actually use a treadmill: a 45-minute tempo run at a fixed 8.5 mph, a 30-minute hill-repeat session cycling between flat recovery and 12-15% climbs, and a 60-minute long run mixing iFit-guided terrain with manual pace changes. The motor handled all three without any perceptible strain, and belt tracking held steady throughout even during the most demanding hill-repeat session, where sudden incline changes put the most torque-varying load on the motor. This is the kind of workout mix where the extra CHP over the 1750 earns its keep most clearly.

Long-Term Durability Notes

Four weeks of hands-on testing can't fully answer a multi-year durability question, so we cross-referenced our impressions against patterns in verified owner reviews spanning one to two years of ownership. The stronger motor shows up favorably here: owners who use the 2450 for serious, frequent running reported fewer motor-strain complaints than we've seen on the 1750 under comparably heavy use, consistent with the idea that the extra CHP provides genuine reserve capacity rather than just a bigger number on a spec sheet.

Belt tracking and tension remain the most common maintenance item reported by owners, in line with essentially every treadmill we've reviewed regardless of price. The touchscreen and console electronics showed a low complaint rate, and the frame drew consistent praise for staying tight and rattle-free even under frequent hard training. NordicTrack's warranty on this model matches the 1750's — a 10-year frame, 2-year parts, and 1-year labor policy — despite the higher price point, which is worth knowing if warranty coverage is a factor in your decision between the two.

As with every NordicTrack model, keeping the belt lubricated on the manufacturer's suggested schedule remains the single most effective thing an owner can do to avoid premature wear, and it matters just as much on the 2450 as it does on any cheaper model in the lineup.

Pros and Cons

How It Compares

The Commercial 2450 sits squarely between two other NordicTrack models most shoppers will be weighing it against.

Read our full review of the step-down modelif you haven't already — the 1750 shares the same deck and cushioning system and delivers a nearly identical day-to-day experience for walkers and moderate joggers at $500 less. The jump to the Commercial 2950buys a further-stronger 4.5 CHP motor and a much larger 32-inch screen, but for roughly $1,700-$2,200 more — a price most runners, even serious ones, will struggle to justify once they've already got the 2450's incline ceiling and motor reserve.

If you're comparing across brands rather than just within NordicTrack's own lineup, ourcommercial treadmill roundupcovers competing flagship and near-flagship machines at similar price points, some of which prioritize deck size or console simplicity over NordicTrack's touchscreen-first approach.

Who Should Skip This Treadmill

It's also worth flagging a subtler group who should skip the 2450: shoppers who are buying based on a spec sheet comparison alone rather than their actual training history. It's easy to look at "4.25 CHP versus 3.75 CHP" and assume more is always better, but the honest truth from our testing is that the difference is imperceptible unless you're regularly pushing pace or incline hard enough to feel the 1750 working near its limit. If you've never owned a treadmill before and don't yet know your own training habits, we'd suggest starting with the 1750 and upgrading later if you find yourself wanting more — it's a far cheaper mistake to correct than the reverse.

If your training is mostly flat-ground walking or easy jogging, you will not feel the difference between this machine and theCommercial 1750, and the extra $500 is better spent elsewhere or simply saved. If you're a serious runner already leaning toward the strongest possible motor and largest possible screen regardless of price, skip straight to the Commercial 2950rather than treating the 2450 as a stepping stone you'll want to upgrade from again later. And if you're still comparing broadly across budgets, our best treadmills for homeguide is a better starting point than committing to a specific NordicTrack tier this early in your research.

One more consideration worth weighing: financing and resale. Because the 2450 sits at a genuinely popular mid-flagship price point, it tends to hold resale value slightly better than either the entry-level 1750 or the far pricier 2950, both of which see steeper depreciation curves in the used market — the 1750 because it's the highest-volume model with the most secondhand supply, and the 2950 because its price ceiling narrows the pool of buyers willing to pay used-market prices for a flagship. If resale value factors into your decision at all, that's a small point in the 2450's favor.

Final Verdict

The NordicTrack Commercial 2450 does exactly what it sets out to do: it takes everything that already works about the Commercial 1750 and adds real, usable headroom for runners who need it. The stronger motor and steeper incline aren't marketing dressing — during hard sessions, we could feel the difference directly, and owners doing serious hill training will feel it too.

The honest caveat is the same one we'd give about any mid-tier upgrade: buy this because your training demands it, not because it's the next model up from the one you were already considering. For walkers and easy joggers, the 1750 remains the smarter buy. For runners who regularly push pace and incline, the 2450 is worth every one of the extra dollars.

If you're still on the fence after reading this far, our practical advice is to think back over your last few months of actual training rather than your aspirational training plan. Runners consistently underestimate how much of their weekly mileage is genuinely easy-paced, flat-ground running, which the 1750 handles just as well as the 2450 does. Buy the upgrade for the training you're actually doing today, not the training you might do someday — you can always trade up later once your mileage and incline demands catch up to the machine.
