A capable entry-level connected treadmill, but its headline smart features are locked behind an iFIT Train Membership, so budget for that subscription before counting on them.

Overview
A connected treadmill (NTL17624) with a 5-inch LCD display, device shelf, 0 to 10 mph speed range, and 0 to 10% incline, running iFIT workouts when paired with a Train Membership.
Most of what's described here, SmartAdjust, ActivePulse, AI coaching, Google Maps routes, requires a paid iFIT Train Membership and either a phone, tablet, or Bluetooth heart rate monitor; the treadmill itself just displays basic stats without a subscription. KeyFlex cushioning is the deck technology meant to soften impact on joints during walking or running. The 0-10 mph and 0-10% incline ranges put this at entry-level speed and grade rather than a machine built for serious hill training or sprint work.
- 5-inch LCD display with integrated device shelf
- 0 to 10 mph speed and 0 to 10% incline range
- KeyFlex cushioned deck for lower-impact strides
- IFIT compatible for streamed workouts (membership required)
Who it's for
Fits someone wanting a basic connected treadmill for walking or light jogging who's willing to pay for iFIT if they want the interactive coaching features. Not a fit for runners wanting higher top speeds or steeper incline than 10 mph and 10%.
Strengths and trade-offs
Drawn from this product's published specifications.
- Adjustable incline up to 10% for varied terrain simulation
- Device shelf built in for a phone or tablet
- KeyFlex deck cushioning aimed at joint impact
- Nearly all smart features require a paid iFIT membership
- Speed tops out at 10 mph, below higher-end treadmills
Performance notes
The 5-inch LCD shows live stats on its own, but the smart features (auto-adjusting speed and incline, heart-rate-based pacing, text-based AI coaching) all route through the iFIT Train Membership rather than working standalone. KeyFlex cushioning is built into the deck to reduce joint impact versus a hard treadmill belt. Bluetooth syncing to apps like Strava and Garmin also depends on the membership rather than being a free standalone function.
