NordicTrack Commercial 1750 vs NordicTrack T Series 6.5Si Treadmill
Quick verdict
Winner on Gym Score: NordicTrack Commercial 1750 (85)
The NordicTrack Commercial 1750 wins on every spec that matters for actual running — bigger motor (3.5 vs 3.0 CHP), longer deck (60" vs 55"), better display, and a 4.5★ rating across 3,500+ reviews vs the Horizon's 3.8★ across 3,000+. The Horizon is a budget runner under $1,000 that's good enough for 2-3 years of light use, but if you'll run more than 3x/week or weigh over 200 lb, the deck is too short and the motor will work too hard.
Choose the NordicTrack 1750 if you're running 3+ days a week, weigh over 180 lb, want a 60" deck for full stride length at speed, and will use iFIT classes.
Read the full review →Choose the Horizon if your budget caps at $1,000, you primarily walk or jog at 5-6 mph, and you don't mind a shorter deck. It's a 2-3 year machine, not a 10-year machine.

The real tradeoff
Deck length is the silent killer here. A 55" deck is fine for walking, but at running paces (7+ mph), tall lifters with long strides will sense the deck edges and have to consciously shorten stride to avoid stepping off. That's a real reason runners over 6' should choose the 60" 1750. Warranty also favors the 1750 (10-year frame vs Horizon's typically shorter coverage), and the resale value gap is significant — the 1750 holds value 2-3x better than the Horizon on the used market.
Skip both if you're under 200 lb, walk-only, and have under 6 ft of usable space. A walking pad like the WalkingPad P1 at /product/walkingpad-p1 fits under a desk and costs a third as much.
Buyer questions
Is the Horizon's 3.0 CHP motor enough for daily use?
For walking and light jogging (under 6 mph), yes. For running at 7+ mph for 30+ minute sessions, the motor runs near its continuous-duty limit, which shortens its lifespan. The 1750's 3.5 CHP has meaningfully more headroom.
How does iFIT compare to the Horizon's app integration?
iFIT is a paid subscription ($39/mo) with thousands of trainer-led runs that control speed and incline automatically. The Horizon's Bluetooth integration is passive — it pairs to apps like Peloton or Zwift but doesn't auto-adjust. If you want hands-off workouts, the 1750's iFIT system wins.
Both fold — but which one folds easier?
The Horizon's hydraulic fold is lighter and easier for one person; it's a lighter machine overall. The 1750's SpaceSaver fold is heavier and benefits from a second pair of hands. Neither folds flat enough to slide under most beds.
