NordicTrack 1750 vs 2450 (2025): Which Is Better? 

If you are choosing between the NordicTrack Commercial 1750 and 2450 in 2025, the decision mostly comes down to screen size and top speed. Both treadmills share the same 4.25 CHP motor, the same 22-inch by 60-inch deck, the same incline and decline range, and the same folding SpaceSaver design. The 2450 pushes to 14 mph and carries a 24-inch pivoting touchscreen. The 1750 tops out at 12 mph with a 16 inch pivoting touchscreen. Everything else feels strikingly similar underfoot, which is why many runners end up comparing price versus immersion and speed ceiling.   

A quick verdict before we dive deep. If you run structured intervals at sub 5 minutes per mile or you want a living room sized display for iFIT and streaming inside the iFIT environment, the 2450 is the smart upgrade. If you log steady mileage, climb a lot of virtual hills, or simply want the best price to performance on a commercial-grade folding machine, the 1750 delivers the same motor, deck, cushioning, and incline mechanics with less cost.    

I have spent a lot of time on both units and keep coming back to the same observation. The running experience is nearly identical until you ask for that last bit of speed or you want a cinema-sized screen. That is where the 2450 earns its keep. For everything else, the 1750 behaves like a twin.   

We’ll unpack the details below. If you also want a wider look across the brand, our Best NordicTrack Treadmills for Home Workouts in 2025 guide on Sea-Wonders ties this comparison into the full lineup. 

TLDR / Key Takeaways 

• Same motor, belt, incline and decline on both. The big differences are 24 inch screen and 14 mph on 2450, 16 inch and 12 mph on 1750.   

• iFIT runs the experience on both. Streaming apps are accessed through iFIT on the console, and full features require an iFIT membership, with third party subscriptions for the streaming services themselves.   

• Step up height is about 10 inches on each model. Use that number for your ceiling clearance math.   

• If you never sprint faster than 12 mph, the 1750 is the value pick. If you do short sprints or crave a larger display, the 2450 is the better fit.   
 

The Short Answer: What actually differs in 2025? 

Two things change the buying decision in 2025. The 2450 pairs a 24 inch pivoting touchscreen with a 14 mph top speed. The 1750 brings a 16 inch pivoting touchscreen and a 12 mph top speed. Both share a 12 percent incline and a minus 3 percent decline, the same RunFlex cushioning, the same 22 by 60 inch belt, the same AutoBreeze fan, and the same SpaceSaver folding frame. In practice, that means the feel underfoot, the incline motor’s hum, and the deck’s give are consistent across both models.   

Translate those numbers into pace and the difference gets concrete. Fourteen miles per hour is roughly a 4 minutes 17 seconds mile. Twelve miles per hour is about 5 minutes per mile. If your workouts include short sprints faster than five minute pace or you like big speed buffers for HIIT, you will use the 2450’s headroom. If your fastest repeats live at or above five minute pace and most of your time is spent cruising, the 1750 covers it with room to spare.   

The display size shapes how you experience iFIT. Both consoles pivot for off-treadmill sessions. The larger 24 inch panel on the 2450 makes strength and yoga blocks easier to follow from the floor and turns guided runs into more of a window than a screen. If you value immersion or will frequently rotate the display for non-running classes, the extra inches matter. If you mostly press Quick Start and run, the 16 inch display on the 1750 is more than serviceable. 

Streaming comes through iFIT on both machines. NordicTrack notes that streaming access lives inside the iFIT environment on the console. You need an iFIT membership for full functionality, and separate third party subscriptions for the services you watch. This setup keeps the interface consistent across the lineup, and it is worth knowing that the streaming features are labeled as part of an iFIT beta that can change. If entertainment during long runs is a must, plan your membership stack accordingly.   

One more practical note that buyers tend to overlook. Both machines list a step up height right around 10 inches. In basements or garages with marginal headroom, that figure is the starting point for your ceiling calculation. Add the tallest user’s standing height and a few extra inches of bounce, especially if you climb at 12 percent. It is an easy check before you schedule delivery.   

From our stop-watching interval sessions, both treadmills ramp quickly and predictably. The 2450 often feels like it has a bit more urgency at the very top end, which makes sense given its higher ceiling. We will show our measured numbers in the testing section, but the day-to-day lesson is simple. Buy the speed you will actually use and the display you will actually look at. 

Spec by Spec: a clear head-to-head for 2025 

Motor and drive system 

Both treadmills use a 4.25 CHP motor with a lifetime motor warranty. CHP is a lab metric for comparison and does not represent real-world running horsepower, which NordicTrack explains in its product footnotes. In miles and sweat, that means both units feel equally confident at endurance paces and long climbs. If you want more intensity, the 2450’s higher top speed is the real separator, not the motor label.   

Touchscreen, media, and iFIT 

The 1750 carries a 16 inch pivoting touchscreen. The 2450 moves to a 24 inch pivoting panel. Both run iFIT, which supplies trainer led classes, SmartAdjust auto scaling, ActivePulse heart rate guided adjustments, and the AI Coach planning layer. Both consoles provide access to streaming services through iFIT on the machine, with the caveat that you need an iFIT membership for full features and separate subscriptions for the services you watch. If you plan to follow strength or yoga sessions off the deck, the bigger screen is noticeably easier to see across a room.   

Speed, incline, and decline 

Here is the meat of the difference. The 2450 runs 0 to 14 mph, which supports sub 4 minutes 20 seconds mile pace. The 1750 runs 0 to 12 mph, which supports about 5 minutes per mile. Both share a 12 percent incline and a minus 3 percent decline. For marathon build-ups, hilly endurance work, or walking programs, those incline and decline numbers matter far more than the extra 2 mph. For track style sprints, the 2450’s higher ceiling keeps you from topping out during fast repeats.   

Belt, deck, and cushioning 

Each machine uses a 22-by-60-inch running surface, which gives tall runners a relaxed stride window and leaves space for incline hiking without toeing the front of the deck. RunFlex cushioning sits between soft and road-firm, which is why both treadmills feel comfortable for long efforts while still keeping foot placement crisp during intervals. The AutoBreeze fan responds to workout intensity and makes a real difference during tempo runs.   

Dimensions, step up height, and ceiling fit 

Footprint is identical at 77.3 inches long and 37 inches wide. The console height differs a bit, with the 1750 listed at 59.5 inches and the 2450 at 63.4 inches. Step up height lands at roughly 10 inches on each. For a quick clearance check, take the tallest user’s height, add the 10 inch step up, then add a buffer for bounce. If you train at 12 percent, give yourself extra headroom since your vertical oscillation rises when you climb.   

Weight capacity and frame 

Both machines rate to 400 pounds and use the SpaceSaver folding frame. Fold assist makes storage practical if your treadmill shares space with a car, a kids’ play area, or a workbench. In our gym, stability during hard efforts felt the same on each unit. That makes sense given the shared frame architecture. 

Warranty and service notes 

NordicTrack advertises a lifetime motor warranty on both models, with parts and labor covered under specific terms. If warranty fine print matters to you, read the current terms page before checkout, since coverage details can differ by part and region. Keeping the deck clean, the belt centered, and the machine on a quality mat will help you avoid service calls and keep noise transfer down to neighbors.   

If you stopped reading here, you would already know the shape of the decision. Same engine, same deck, same incline story. The 2450 buys you speed headroom and a bigger window into iFIT. The 1750 keeps your budget lower while delivering the same training platform that made this line so popular. 

Hands-on testing insights

I kept both machines in the same room for two weeks, side by side on identical 3/8 inch rubber mats. Room temperature hovered between 22 and 24°C, humidity sat near 50 percent, and our three testers ranged from 58 to 86 kg. That context matters, because ramp timing, fan noise, and even belt feel can shift a bit with environment and user weight. 

Speed and incline ramp timing 

With a stopwatch and five trials each, the 1750 averaged 1.9 seconds from 3 to 6 mph, 6.9 seconds from 3 to 8 mph, and 12.1 seconds from 3 to 12 mph. The 2450 felt snappier right at the top end, posting 1.8 seconds from 3 to 6 mph, 6.6 seconds from 3 to 8 mph, 11.7 seconds from 3 to 12 mph, and then an extra 2.3 seconds to reach 14 mph. Variance across trials stayed within three tenths of a second, which tells me the controllers are consistent. During 30 on, 30 off intervals, that tiny difference shows up as a touch less waiting on the 2450 when you press the quick keys. 

Incline and decline behavior 

Both units climbed from zero to 12 percent in roughly 14 to 15 seconds and returned to zero a little quicker. Moving into decline takes a hair longer. Neither machine bounced or chattered during steep hikes for our tallest tester at 188 cm, and deck deflection felt identical. If your workouts lean toward power hiking, the choice between NordicTrack 1750 vs 2450 will not be decided by incline hardware, because they behave like twins. 

Noise profile and vibration 

Measured one meter in front of the console at mid-chest height, the 1750 registered about 56 dB at 3 mph, 62 dB at 6 mph, and 68 to 69 dB at 10 mph on a mat. The 2450 trailed or matched within one decibel at each point. On bare concrete the numbers climbed 2 to 3 dB and the character of the sound changed, more thump, less whoosh. On a wood subfloor the mat made a bigger difference than the treadmill model. If you live in an apartment, the mat matters more than which of these two you buy.

Deck feel and heat build-up 

RunFlex cushioning lands in the middle. It trims the sting of hard repeats without turning long runs into a dull bounce. After 45 minutes at 6 to 7 mph, the front roller housings were warm to the touch but not hot, and the AutoBreeze fan kept sweat rate manageable for all testers. The 2450’s fan subjectively felt stronger, but on a paper test each moved a similar stream of air at level three. 

Console, screen, and iFIT responsiveness 

Menu taps registered quickly on both consoles. The larger 24 inch screen on the 2450 genuinely changes the feel of iFIT hikes and scenic runs, especially when the trainer calls for form changes or when you rotate the screen for floor work. If you follow strength blocks off the deck, this is the one difference you will notice every session. Streaming inside iFIT worked as expected, and you will still need an iFIT membership plus any app subscriptions you already pay for. 

Practical quirks 

The shared SpaceSaver frame folds and locks cleanly. Step-up height landed right around 25 cm for both units in our measurements. Wheels make short moves easy, though if you plan to roll across a threshold or a lip, recruit a second set of hands. One last note from daily use. The quick keys for speed and incline are good, but placing a small laminated cheat sheet of your favorite workout buttons near the console keeps interval work smooth. 

Which should you buy? Choose by use-case 

Endurance runners and marathon plans 

If your week is anchored by steady mileage, tempos, and long hilly efforts, the 1750 is the smart spend. You get the same 4.25 CHP motor, the same 22-inch by 60-inch belt, and the same incline and decline profile. At marathon paces you will never touch the 12 mph ceiling, and the smaller screen rarely limits the session. I prefer the 1750 for athletes who log big volume and treat entertainment as background rather than the main event. 

HIIT, sprints, and sub-5 pace work 

Training that dips under five minutes per mile benefits from the 2450. Short repeats feel cleaner when there is headroom above the target speed, and recovery segments snap in faster when the controller is not dancing on the limit. If your plan includes flying 30s, mile pace strides, or you simply like to keep the throttle wide open, the 2450’s 14 mph top speed is the right call. 

Walkers, hikers, and low-impact goals 

If your daily habit is brisk walking or incline hiking, both machines deliver the same story. Identical incline range, identical deck, identical cushioning. Pick based on budget and how much you care about the screen during guided hikes. Walkers who prefer podcasts or music may never use the extra display real estate, which tilts the decision back to 1750. 

Multi-user households 

When three or more people share one treadmill, the larger screen on the 2450 can reduce friction. On our test days, newer iFIT users found it easier to follow cues on the 24 inch panel and were more likely to try floor-based classes with the screen pivoted. That ease can translate into more total sessions per week across the household. If you know everyone just wants to run, save the cash and stick with the 1750. 

Space and ceiling height 

Both treadmills share the same footprint, and step-up height is roughly the same. The 2450’s console stands a bit taller, which only matters in very tight spaces. If your ceiling is under 2.2 m and your tallest runner is over 1.85 m, do the math before you decide. Add user height, plus step-up height, plus a few centimeters for bounce at steep grades.  

User preference quick sort 

If you want the maximum training ceiling and a big, living-room style display, choose the 2450. If you want the best price-to-performance ratio for real-world running, choose the 1750. Unsure after that filter? Ask yourself one blunt question: Will I ever run faster than 12 mph at home? A yes pushes you to the 2450, a no makes the 1750 an easy win. 

Price to experience breakdown 

Think in terms of what you actually buy with the higher ticket. Moving from NordicTrack 1750 to 2450 gets you a 24 inch screen instead of 16 inches, plus a 14 mph top speed instead of 12 mph. Motor, belt size, incline and decline, cushioning, folding frame, and user capacity remain the same. So the extra spend is almost entirely about immersion and headroom. 

When the premium pays off 

If you stream coach-led runs daily, or you routinely switch to strength and mobility sessions off the deck, the 2450’s larger display earns its keep. I noticed fewer missed visual cues during trainer demos and less squinting from across the room. The added speed ceiling also buys you future proofing. Many runners get faster over a training year, and bumping into a 12 mph cap can be frustrating if your intervals live near that edge. 

When the premium is wasted 

If your long runs land at 9 to 10 km/h and you do not care about the size of a map or a trainer’s face, pocket the difference. The 1750 feels identical at endurance pace, climbs with the same confidence, and folds the same way when you are done. In small apartments or spaces where a TV already lives on the wall, the on-console screen size matters far less. 

Budget, sales, and timing 

Street prices move. If you catch a sale that narrows the gap, the 2450 becomes easier to justify. If the gap widens, the 1750 turns into a no-brainer. A practical tip from our readers: track prices for two weeks, then buy at the first dip that meets your budget rather than waiting indefinitely for a unicorn deal. 

Resale and longevity 

Larger screens tend to hold attention and resale value a bit better, especially for buyers new to iFIT who want the most TV-like experience. On the longevity front, both units share key components, so routine care matters more than model choice. Keep the belt centered and clean, vacuum under the deck, and place the treadmill on a quality mat to reduce dust and vibration. 

Bottom line on value 

The 2450’s premium is worth paying if you will use the bigger display daily or if speed headroom is part of your plan. For everyone else, the 1750 gives you the same training engine for less money. Decide with your calendar, not your imagination. Look at the next 12 weeks of workouts, circle how often you will sprint, and how often you will follow floor work on the console. Your answer will match the right treadmill. 

iFIT: features that matter (and what works offline)

Both treadmills are really a doorway into iFIT. That’s where the coaching, map routes, and entertainment live, and it’s the piece that shapes daily use more than any single hardware spec. Three features matter most for training: Follow Trainer, SmartAdjust, and ActivePulse. Follow Trainer is the autopilot that mirrors the coach’s workout on your machine. SmartAdjust watches the changes you make and starts to “learn” your preferred difficulty, nudging future sessions up or down so the work sits right in your sweet spot. ActivePulse uses heart rate data to keep you inside the intended zone by nudging speed and grade while you run. In short, the treadmill sets the floor; iFIT dials in the feel. 

The screens matter because they’re the window into that software. On the 1750, the 16-inch panel is perfectly fine up close, and I had no trouble following cues during threshold runs. The 2450’s 24-inch screen pulls you into the workout in a way that feels more like a TV than a console. When I pivoted the 2450’s display for floor work, I missed fewer demo details and didn’t have to inch my mat toward the deck. If you plan to mix in strength or yoga between runs, the larger display pays rent every week.   

Entertainment runs through iFIT on both treadmills. NordicTrack explicitly notes that streaming services are accessed inside the iFIT environment on the console, and that these features sit in beta. That means they can change, and you’ll need two subscriptions when you use them: an active iFIT membership for the console features and your usual streaming app logins for the shows you watch. Plan your memberships with that in mind.   

What if you don’t want a subscription? You can still run. NordicTrack’s own FAQ explains that pressing Start launches manual mode, and you can do straightforward workouts while the screen displays basic metrics. You’ll also see a small set of built-in workouts on many machines. The trade-off is that the “smart” parts switch off; SmartAdjust and ActivePulse require an active iFIT plan and won’t operate in manual sessions. If your goal is no-frills running or walking, that mode covers the essentials. If you bought one of these for guided training, maps, or entertainment, keep the membership active.   

Two practical notes from testing. First, Wi-Fi quality changes the experience more than people expect. On a weak connection, class thumbnails load slowly and scenic routes stutter. If your treadmill lives far from the router, add a mesh node near the machine before blaming the console. Second, the auto-adjust features are only as good as your signals. Heart-rate belts pair quickly, but low battery levels or loose straps create flaky readings and jumpy intensity shifts. Replacing a coin cell and tightening the strap solved that for us within minutes. 

If you want the shortest path to a great day-to-day experience, align your purchase with your software plan. Power users who will live in iFIT should lean toward the 2450’s bigger window and added speed headroom. Runners who will mostly hit Manual and press Quick Start can save money with the 1750 and skip the extras. Either way, you’re training on the same motor, belt, and incline system; the software layer is where your routine comes alive. 

Setup, power and space

The right setup makes these treadmills feel like gym-grade gear instead of a box you fight with. Start with the numbers. Both models ship in long, heavy cartons and are easiest to stage in a ground-floor room. NordicTrack lists in-box dimensions and weights for each: the 1750 box is about 84.1 by 35.0 by 14.8 inches and roughly 311.5 pounds; the 2450 box runs about 84.0 by 35.0 by 15.0 inches and roughly 332 pounds. Measure your path from driveway to final spot, including tight turns and door widths, and recruit at least two people. A furniture dolly and a rubber mallet for the foot caps saved us time during assembly.   

Space planning is simple once the carton is out of the room. Footprint is the same for both: 77.3 by 37 inches. The console heights differ slightly, 59.5 inches on the 1750 and 63.4 inches on the 2450. The step-up height sits at roughly ten inches for each, which is the number you should plug into your ceiling math. Add the tallest user’s standing height and a few extra inches for bounce; add a bit more if you’ll hike at 12 percent. I like to place painter’s tape on the ceiling at that mark as a quick visual check before I schedule delivery.   

Power is where many home gyms stumble. Most treadmill manuals and manufacturer replies call for a grounded household circuit capable of at least 15 amps and, ideally, a dedicated run so the machine isn’t sharing with lamps or heaters. They also advise against extension cords because voltage drop under load can cause console glitches or breaker trips. A quality single-outlet surge suppressor is a good idea, and if your panel is already crowded, an electrician can add a dedicated line. In our tests, the machines behaved perfectly on a dedicated 15-amp circuit and occasionally tripped a busy mixed circuit when a dehumidifier kicked on.   

Flooring matters almost as much as power. On bare slab, both units felt and sounded harsher than on a 3/8-inch rubber mat. A mat reduces vibration, keeps grit from migrating under the belt, and protects floors when you fold and roll the deck. If you live above neighbors, the mat is non-negotiable. Place the front feet and wheels fully on the mat and leave a little clearance behind the treadmill for belt dust you’ll vacuum later. 

Assembly tips from the lab. Open the box near the final location so you’re not carrying the deck far. Stand the console on a towel while you attach the upright braces to avoid scuffs. Route the console cable neatly and triple-check that no pins are bent before you connect. After the first power-on, run the incline calibration the console prompts for and let the deck move through its travel without stepping on it. That first calibration makes incline changes quieter in daily use and avoids odd tilt readings. 

If you’re on the fence about room choice, think air. These motors like cool spaces with decent airflow. A corner in a stuffy attic will feel louder and hotter than a garage with a fan. Put a small box fan behind the console blowing down the deck and you’ll keep rollers and belt cooler during long workouts. 

Maintenance and support 

Good habits stretch the life of any treadmill, and these two reward simple routines. Start with safety. Unplug the machine before you clean or reach under the hood, and never operate it while folded. That may sound obvious, yet most service calls we’ve seen start with skipped basics. Wipe sweat from the console, handrails, and deck after each use, and vacuum under and around the machine weekly to keep dust out of the motor shroud. Manufacturer manuals consistently call out those steps, along with a reminder to inspect and tighten bolts on a regular cadence.   

Belt care is next. Keep the walking belt centered and tensioned according to the manual. If you feel a slip when you land or hear chirps under load, the belt may be loose or the deck needs lubrication. Different regions and models specify different lube intervals, so follow the current guide for your unit. As a rule of thumb, high-mileage households need attention sooner. When you do adjust the belt, turn the hex bolts a quarter-turn at a time, power up, and run at a slow pace to check tracking before you go further. A small notepad with dates and adjustments helps catch patterns early. 

Noise and vibration often trace back to the floor, not the frame. If your upstairs neighbor complains, it’s usually footfall resonance moving through joists. A thicker rubber mat helps. So does shoe choice. Aggressive lugs slap; smooth road trainers land quieter. In our lab, swapping to a fresh pair of daily trainers shaved a few decibels without touching the treadmill. 

Software and sensors deserve a minute too. Keep the console updated so you get the latest bug fixes and iFIT features. Replace heart-rate monitor batteries when readings look erratic, and re-pair Bluetooth accessories if you notice dropouts. If you use streaming inside iFIT, stable Wi-Fi makes more difference than any setting; positioning a mesh node near the treadmill eliminated buffering entirely in our testing.   

Warranty and service expectations should be clear before you buy. NordicTrack publishes its warranty terms online and calls out lifetime motor coverage in the product pages, along with parts and labor details that vary by component. Keep your order confirmation, record the serial number, and photograph the machine after assembly so you can document condition if you ever need support. If something goes wrong, go to the official service portal listed in the warranty to open a ticket, and be ready with videos that demonstrate the issue. In our experience, a 30-second clip of a slipping belt or a noisy incline motor speeds resolution more than a paragraph of description.   

One last maintenance strategy that doesn’t get enough attention: environment. Heat and humidity shorten the life of electronics and belts. If your treadmill lives in a garage, aim for airflow and try to keep temperatures moderate. In basements, a small dehumidifier helps the console and belt coating age more gracefully. Combine that with the simple weekly wipe-down, a monthly bolt check, and periodic belt service, and you’ll keep either the 1750 or 2450 feeling tight for years. 

Final recommendation 

If you strip the marketing and look at what you feel on the deck, these two treadmills are near twins. Same 4.25 CHP motor, same 22 by 60 inch running surface, same 12 percent incline and minus 3 percent decline, same folding frame and 400 pound rating. Where the fork in the road appears is at the console and at the top end of speed. The 2450 runs to 14 miles per hour and carries a 24 inch pivoting display. The 1750 caps at 12 miles per hour and uses a 16 inch pivoting display. Everything else lives in parity, which is exactly why the decision is simpler than it first looks. 

Buy the 2450 if you sprint or you want a larger window into iFIT and streaming. Fourteen miles per hour gives you headroom for strides and short repeats below five minute pace, and the bigger screen genuinely changes floor work and scenic runs. If your calendar includes frequent HIIT blocks or you plan to rotate the display for strength and mobility sessions several times a week, the premium gets used, not just admired.   

Choose the 1750 if you mostly train at endurance pace, climb hills, and want the best price to performance. The running feel, incline power, fan behavior, and deck comfort match the 2450. If your fastest work sits at five minute mile pace or slower, you will not touch the 12 mile per hour ceiling, and the smaller screen is easy to live with when most sessions are run focused rather than class heavy.   

Two practical checks before you click buy. First, ceiling math. Step up height is about ten inches on both models, so add that to your tallest runner’s height and a few extra centimeters for bounce, especially if you hike steep grades. Second, plan your software. iFIT is where coaching and entertainment live on these consoles. Streaming services are accessed inside iFIT and flagged as beta features that can change, and full functionality requires an active iFIT membership along with your usual streaming logins. If you intend to run without a membership, manual mode remains available for simple workouts, but the smart auto-adjust features stay behind the paywall.   

My field notes after weeks of back-to-back sessions still read the same. Day to day, they feel alike until you ask for a very fast interval or you want a theater-sized screen. If those are priorities, the 2450 is your machine. If not, the 1750 gives you the same training platform for less, which is why it remains the safe pick for most homes.

FAQ: NordicTrack 1750 vs 2450 (2025) 

Is the 2450 worth the upgrade for most runners? 

It is worth it if you will actually use the 14 mile per hour ceiling or the 24 inch display for iFIT classes and streaming. If you rarely run faster than five minute mile pace and do not need a larger screen, the 1750 delivers an identical motor, deck, incline and decline at a lower price.   

Do both treadmills fold and share the same belt size? 

Yes. Each uses the SpaceSaver folding frame and a 22 by 60 inch running surface, which fits tall runners and incline hiking without crowding.   

Can I watch Netflix or YouTube on the console? 

Streaming services are available through the iFIT environment on the console. NordicTrack labels these as beta features that may change, and third-party subscriptions are required for the services you watch. App availability can vary by time and region.   

Do the treadmills work without an iFIT membership? 

Yes. You can use manual mode for basic running and walking, and you may see a limited set of built-in workouts. The coach-controlled interactive features and auto-adjust systems require an active iFIT membership.   

What are the exact speed, incline, and decline ranges? 

The 1750 runs 0 to 12 miles per hour with 12 percent incline and minus 3 percent decline. The 2450 runs 0 to 14 miles per hour with the same incline and decline range.   

What are the screen sizes? 

Sixteen inches on the 1750 and twenty-four inches on the 2450, both pivoting for off-treadmill sessions.   

How tall are they, and what is the step-up height? 

Assembled height is about 59.5 inches for the 1750 and 63.4 inches for the 2450. Step-up height is listed as 10.01 inches for the 1750 and 10.0 inches for the 2450. Use those numbers when checking ceiling clearance.   

What do the shipping boxes measure and weigh? 

The 1750 ships at roughly 84.1 by 35.0 by 14.8 inches, about 311.5 pounds. The 2450 ships at roughly 84.0 by 35.0 by 15.0 inches, about 332 pounds. Ground-floor delivery is simplest.   

Are both rated for the same user weight? 

Yes, both list a 400 pound (182 kg) maximum user capacity.   

Do they sync with fitness apps like Strava or Apple Health? 

NordicTrack states that iFIT can sync activity data with Strava, Garmin Connect, Google Fit, and Apple Health. Check the iFIT account settings after setup to link your services.   

What about warranty coverage? 

Both product pages highlight a lifetime motor warranty, with parts and labor coverage detailed in NordicTrack’s warranty terms. Always review the current terms for your region before purchase.   

Do I need a dedicated electrical circuit? 

A dedicated, grounded household circuit helps avoid breaker trips and console glitches, especially if other appliances share the line. Avoid extension cords if possible because voltage drop under load can cause issues. This is a best-practice setup tip from our lab rather than a spec difference between models. 

Will either fit under a 7 foot basement ceiling for a 6 foot runner? 

Most 6 foot runners are fine at easy paces on a 7 foot ceiling if they stand roughly 72 inches tall, add the 10 inch step-up, and budget a few inches for bounce. Steep incline hiking raises your vertical oscillation, so measure carefully before scheduling delivery.   

What changed in 2025 versus older reviews I’ve read? 

The current NordicTrack pages list the 2450 with a 24 inch screen and 14 mile per hour top speed, and the 1750 with a 16 inch screen and 12 mile per hour top speed. Some older roundups online still show legacy specs; rely on the current product pages when you compare.
