Sunny Health & Fitness Smart Wi-Fi Treadmill
This Sunny treadmill, the Sunny Health & Fitness Smart Wi-Fi Treadmill (model SF-T724012), is a fully motorized, 2HP folding treadmill built around Wi-Fi and Bluetooth connectivity to the free SunnyFit app, with 15 auto-incline levels and a straightforward LED console instead of a touchscreen. It leans on your own phone or smart TV to run the guided workouts and virtual routes that pricier connected treadmills build into a bolted-on screen.
- Wi-Fi and Bluetooth both built in, casting to a smart TV or pairing to the free SunnyFit app for 10,000+ virtual routes and 1,000+ training videos with no subscription fee
- 2HP brushless motor covers a quiet 1-9 MPH range for walking, jogging, and light running
- 15 automatic incline levels up to 12.3% grade with quick-adjust buttons, no manual crank
- 50 in x 16 in shock-absorbing deck built for longer, lower-impact sessions
- Space-saving fold with a soft-drop hydraulic system, transport wheels, and dual bottle holders for everyday convenience
Where the Smart Wi-Fi Treadmill lands against the other Sunny models in our catalog: Beats the Sunny Health & Fitness Auto Incline Treadmill (fully assembled) on connectivity, adding Wi-Fi smart TV casting on top of the same SunnyFit app, while that model's 2.5 HP motor and 15% incline edge it out slightly on power, Loses to the Sunny Health & Fitness Smart Wi-Fi Auto Incline Treadmill on motor size and top speed (3 HP, 12 MPH), but carries nearly four times the review base, 9,220 ratings against 2,244, Sits far below the Sunny Health & Fitness 45% Auto Incline/Decline Treadmill's incline range, a different class of machine built for hill training rather than everyday cardio, Carries by far the largest review base of any Sunny model we stock, 9,220 ratings against a few thousand at most for the rest of the lineup.

Why the Smart Wi-Fi Treadmill earns its spot in the budget-smart tier
Wi-Fi, not just Bluetooth
Most budget-tier treadmills in this shop pair over Bluetooth alone. This model adds Wi-Fi on top, casting workouts straight to a smart TV instead of relying only on a phone screen, while still keeping Bluetooth for direct app pairing.
Automatic incline with no manual crank
15 incline levels move with the quick-adjust buttons on the console, up to a 12.3% grade, so intensity changes without stepping off the belt to turn a dial by hand.
A shock-absorbing deck at the budget tier
The 50 in x 16 in running surface is built with shock absorption to ease joint impact, a feature that often disappears once a treadmill drops into the budget tier.
What owners keep saying
Three named owner reviews appear on Sunny's own store page for this exact SKU. We checked them against reviews on other Sunny treadmill pages in this catalog for the review-pool duplication problem found elsewhere in the lineup, and this text held up as specific to this model. That is a small sample of three owners posted on the seller's own site, worth reading alongside the 9,220-rating Amazon aggregate below.
I think this is a great machine. Automatic incline, preset speed and incline buttons, mirrors to my TV using the app. Assembly was easy. Can’t lose using this machine.
assemblyThis is a very well treadmill!... The app is easy to use and focused on fitness. Instead of AI generated graphics and virtual worlds, the videos showcase actual trails and sights. The best part - the app connects quickly with the machine and never drops the connection!
valueSo far, so good. Used it almost every day for the last week and a half. The incline is great and kicks my butt. Definitely download the app. You can save all of your workouts and play scenic routes on your tv to make the path a little less boring.
valueWi-Fi casting, auto incline, and a SunnyFit app subscription you never have to pay for.
Shop on Amazon →The honest cons
- Sunny publishes 2.0 HP as a peak figure with no continuous-duty rating, so it's hard to know how it holds up 20 minutes into a real running session rather than a quick burst
- Parts and electronics warranty runs just 180 days, well short of the 1-year-plus parts coverage several competing budget treadmills in this shop carry
- Top speed caps at 9 MPH, fine for walking and jogging but limiting for anyone training for faster interval running
- Incline maxes out at 12.3% grade, about 6.85 degrees, modest next to Sunny's own 45% incline/decline model or the 15% MERACH machine in this comparison
Sunny Health & Fitness Smart Wi-Fi Treadmill vs Xterra TRX1000 vs MERACH 15/18%
All three machines here sit in the budget-to-mid range, so the real differences between this Sunny Health & Fitness model and its rivals show up in motor sizing, incline depth, and whether connectivity means an app, Wi-Fi, or nothing at all.

FAQ
Is the Sunny Health & Fitness Smart Wi-Fi Treadmill the same as Sunny's manual treadmill models?
No, this model, SF-T724012, is a corded-electric treadmill with a 2HP motor and 15 automatic incline levels. Sunny Health & Fitness also sells non-motorized, manually-inclined treadmills under different model numbers, so if you're specifically after a manual machine, this isn't it. Check the model number on the listing before you buy if that distinction matters to you.
What's the difference between the Wi-Fi and Bluetooth connections on this treadmill?
Wi-Fi lets the treadmill connect directly to your home network to cast workouts to a smart TV, while Bluetooth pairs it to your phone for the SunnyFit app's live tracking and virtual routes. Both work through the same free SunnyFit app, and neither requires a paid subscription to use.
Does the treadmill fold for storage?
Yes, it uses a space-saving foldable design with a soft-drop hydraulic system, so the deck lowers slowly and safely instead of dropping on its own, and it moves on built-in transport wheels once folded.
How fast and how steep does this treadmill go?
Speed runs from 1 to 9 MPH. Incline runs through 15 automatic levels up to a 12.3% grade, about 6.85 degrees at the steepest setting, adjusted with quick buttons on the console rather than a manual crank.
Is a 2HP motor enough to run on, not just walk?
It handles walking, jogging, and light running comfortably within the 1-9 MPH range, but Sunny publishes the 2HP figure as a peak rating rather than a continuous-duty number. Continuous duty is what predicts how a motor performs 20 minutes into a session rather than in a short burst, so if daily hard running is the plan, a treadmill with a stated continuous-duty horsepower is the safer bet.
What's included in the box and what does the warranty cover?
The box includes the treadmill, lubricant, a safety key, a tool kit, and the user manual. Sunny backs the frame with a 3-year structural warranty, while other parts and components carry a shorter 180-day warranty, worth knowing before you count on longer coverage.
The verdict
The short version: the Sunny Health & Fitness Smart Wi-Fi Treadmill is a genuinely well-reviewed budget-smart pick. Amazon's 9,220 owners rate it 4.3 out of 5, more feedback than any other Sunny treadmill in our catalog. A 2HP brushless motor, 15 auto-incline levels up to 12.3%, and dual Wi-Fi and Bluetooth connectivity to the free SunnyFit app put real connected-fitness features on a machine that costs less than most treadmills with a screen bolted on. The catch is in what Sunny doesn't publish: the 2HP rating is a peak figure, not a continuous-duty number, and the parts and electronics warranty runs out at 180 days.
Buy it if you want Wi-Fi casting and app-guided workouts without paying premium-connected prices, and you plan to walk, jog, or run at a moderate pace. Skip it if you're training for real hills, the incline tops out under 7 degrees, or you want a machine built for daily hard running rather than home cardio.
