Head to head
NordicTrack T 6.5 S vs ProForm Carbon TL
Two iFIT folding treadmills compared: belt, display, warranty, cushioning, and value.
#1 in our rankings · Best overall
NordicTrack T 6.5 S Treadmill
Best for: Households that want one treadmill for walking, jogging, and running, with guided training built in.
#3 in our rankings · Best iFIT value
ProForm Carbon TL Treadmill
Best for: Buyers who want iFIT guided training and a folding treadmill without paying the NordicTrack tier.
Our recommendation
Buy the NordicTrack if you want the larger belt, the longer parts warranty, and the more established iFIT package. Buy the ProForm Carbon TL if you want the same speed and incline range with quick controls at a lower tier, and you accept a basic display and shorter warranty.
Belt and motor
The NordicTrack's 20 by 55 inch belt with a 2.6 CHP motor suits a wider range of runners. The Carbon TL's belt and motor suit walking and jogging well but are less documented for heavy running use.
Display and controls
The NordicTrack pairs a 5-inch LCD with a device shelf for full iFIT video on your own device. The Carbon TL's 5-inch display adds QuickSpeed and QuickIncline one-touch controls, which suit interval sessions better.
Warranty and cushioning
The NordicTrack offers 10 years on frame, 2 years on parts, and 1 year on labour, against the Carbon TL's 10 years on frame and 1 year on motor, parts, and labour. The Carbon TL counters with ProShox cushioning, while the NordicTrack uses KeyFlex cushioning.

Strengths and limitations
NordicTrack T 6.5 S Treadmill
Strengths
- The 20 by 55 inch belt suits walking, jogging, and running for most users, with a 2.6 CHP motor that handles daily use without strain.
- iFIT trainers auto-adjust speed and incline through global workouts and studio classes, which keeps training varied without planning sessions.
- SpaceSaver folding frame with a foot-bar assisted drop folds the deck away after use, and the 5-inch LCD shows live stats clearly.
Limitations
- The 10 mph top speed and 10% incline cap serious interval training compared with higher-spec running machines.
- iFIT's full library needs a membership after the included trial period, so the guided experience needs a paid membership after the trial.
- At around 200 lb assembled, it needs two people for assembly and a dedicated spot even when folded.
ProForm Carbon TL Treadmill
Strengths
- iFIT compatibility with a 30-day family trial gives trainer-led global workouts and studio classes, with trainers auto-adjusting speed and incline.
- ProShox cushioning softens impact for daily walking and jogging, and QuickSpeed and QuickIncline controls jump straight to a chosen pace or grade.
- SpaceSaver folding frame with transport wheels clears floor space after sessions, and the 5-inch high-contrast display shows incline, speed, distance, and calories.
Limitations
- Top speed of 10 mph and 10% incline limit advanced interval training, like the NordicTrack at this tier.
- The frame and motor warranty is shorter than the NordicTrack's, with 10 years on frame and 1 year on motor, parts, and labour.
- No touchscreen: the display is a basic LCD, so immersive iFIT video needs your own phone or tablet.

Questions, answered
Which is better for running?
The NordicTrack, thanks to its documented 2.6 CHP motor and 20 by 55 inch belt. The Carbon TL suits walking and jogging better than heavy running.
Do both need iFIT memberships?
Both include a 30-day iFIT family trial. After the trial, the full library needs a membership, though manual training works without one on both machines.
Which folds smaller?
Both use SpaceSaver-style folding frames with transport wheels. Check each model's folded dimensions against your storage spot, since neither publishes identical folded measurements.
