Nordictrack T Series T6.5s Review: Best Incline Under $800?
Sep 27, 2026
In this nordictrack t series t6.5s review, the short answer is that this $799 treadmill is the smartest pick in our guide if you want an app to run the incline for you. It sits at number two of ten in our best incline treadmills ranking, behind pricier machines with steeper grades. The T6.5S carries a 2.8 HP motor, a 20 by 55 inch belt and a 300 pound user limit. The T Series listing holds 4.3 stars from 32,265 Amazon ratings, and it ranks number 14 in Treadmills on Amazon. For walkers, joggers and iFIT fans, the value is hard to beat.
The headline feature is automatic control. Trainers inside iFIT adjust speed and incline to match the terrain on screen, so a climb starts before you think about pressing a button. Additionally, the 0 to 10% range and 10 MPH top speed cover walking, jogging and steady endurance runs. KeyFlex cushioning softens each footfall, which matters on a 55 inch deck that suits most strides. Meanwhile, the 5 inch LCD shows heart rate and speed, and Bluetooth plus a built-in speaker let you stream audio. In practice, folding takes seconds and the foot bar lowers the deck for you, though the 203 pound frame is still heavy to shift.
For the money, few incline treadmills at this price include auto adjustment. However, the incline tops out at 10%, so the 20% and 25% models higher in our guide win on steep hill work. On top of that, guided training needs an iFIT membership after the included 30 day family plan, which covers up to five users and carries a $39 value. By contrast, the warranty is generous: 10 years on the frame, 2 on parts and 1 on labor. Folded, it measures 78.5 by 35.5 by 14.5 inches, which fits a closet corner in a small home gym. Skip it if you want brutal grades; buy it if coaching keeps you moving.
