How they differ in real use
Built from our treadmills scoring, each product's published specifications, and verified owner feedback — not hands-on testing.
Both the NordicTrack Commercial 2450 and the Horizon Fitness 7.4 AT Studio Series Treadmill made our Top 5 Treadmills, at #1 (best overall) and #3 (best value). 22" HD touchscreen with iFIT that auto-adjusts incline and speed during workouts. 3.6 CHP motor and -3% to 15% incline range for complete training. The Sole F80 that previously held this spot is currently unavailable on Amazon US, so Horizon's 7.4 AT takes over as the no-subscription pick: a 3.5 CHP RapidSync motor, a 22" x 60" deck with 3-zone variable cushioning, 0-15% incline and a 350 lb user limit, backed by a lifetime frame and motor warranty plus 5 years on parts. Against the 7.0 AT below it adds a wider deck, a stronger motor and longer parts coverage; unlike the NordicTrack and Peloton above, it has no touchscreen, so classes stream from your own tablet over Bluetooth FTMS.
