Sunny Health & Fitness SF-T7718SMART Treadmill Review

The Sunny Health & Fitness SF-T7718SMART Treadmill is the newly released (2022) version of the classic version (Sunny Health & Fitness SF-T7718). Both treadmills have similar features except for one or two differences.  

The newer version does not have a sound system as the old version but it does have Bluetooth connectivity that connects to the SunnyFit workout app via a smartphone device; and the big deal about this workout app is that it allows you to explore workout resources such as exercising on virtual trails, tracking your workout progress real-time, achieving workout goals with customized workout plans, having access to over 100 workout videos, sharing workout experiences, and more.  

This is a compact treadmill that is designed for home use. Primarily made for walking, jogging, and light running workout activities. 

Its simplicity is amazing because it does not require installation; the console stands, the handrails, and the tablet holder are all foldable.

The Frame & Construction 

Sunny Health & Fitness SF-T7718SMART Treadmill

The Sunny Health & Fitness SF-T7718SMART Treadmill is constructed on a steel frame that could support up to 250 lbs./113 kg maximum user weight capacity.  

Indeed, other parts such as the side rail covers, the motor cover, and the console post covers are made of durable plastic.  

Despite the treadmill’s size, it is stable due to the overall base framework that features adjustable levelers at the rear. Thus, users can tweak it for improved stability on a platform that is not entirely balanced. 

Although, it will be wise to place the unit on a protective rubber mat to prevent floor damage since it weighs about 118 lbs./53.5 kg. Moreover, this will also boost the overall stability experience.  

The overall assembled dimensions are 62.6’’ long by 29.3’’ wide by 47.6’’ high. To put it differently, the workout area the treadmill requires would be a space with measurements of 5’2’’ (159 cm) length by 2’44’’ (74.4 cm) width, plus an additional clearance of at least 2’ on both sides and 3’ at the rear.  

The treadmill could fit under the bed/couch when you wish to put it away because it could be folded to become only 8.3” high. So, a couch/bed that has a little space higher than 8.3” underneath it could be used as a storage area for the treadmill.  

Still, you can store it vertically against the wall.  

There are transport wheels designated at the front base for the purpose of relocating the treadmill around the room.  

The Deck of the Sunny Health & Fitness SF-T7718SMART Treadmill 

The deck of this treadmill is equipped with a shock-absorbing system that makes the user’s joints less likely to be stressed because of jogging or running.  

Its step-up height is about 3’’, and it does not have an incline system. What this means is that users will be able to get on and off the treadmill easily but won’t be able to adjust the angle of the running surface for a more intense workout.  

The tread belt/running surface dimensions are 47’’ long by 20’’ wide. This will be suitable for users that are up to 6’ tall for walking and jogging but might be restrictive when it comes to sprint running.  

Finally, there is a lubrication reminder when it’s time to apply oil to the tread belt. The treadmill beeps every 10 seconds each time it has been used for 188 miles.

The Motor 

The Sunny Health & Fitness SF-T7718SMART Treadmill is an electric unit; thus, it comes with a 2.5 horsepower motor that provides a speed range of 0.6-9 mph. Therefore, the treadmill needs to be plugged into a 110-120 v DC electric source. 

The speed could gradually be increased or decreased by 0.1 mph via the +/- buttons on the console. However, there are also 3 mph and 6 mph quick speed buttons that will enable you to jump-start your workout at a high-speed level.

Another way the speed gets adjusted is when any of the 9 preset workout programs is selected, then the speed will automatically adjust to the predetermined speed level incorporated for the program.  

The motor is energy-efficient and strong enough to provide the drive needed for walking, jogging, and light running activities without bowing to overheating or breaking down even if you walk out longer.  

Having said that, it is recommended that the treadmill be turned off for 10 minutes after every 2 hours of straight use. 

When it comes to how quiet and smooth the motor’s operation is; it will suffice to say it is smooth and quiet. Thus, you can use the treadmill, and people in other rooms and apartments will not be disturbed by your workout activities.  

However, someone staying in the same room where the treadmill is being used may have a difficult time trying to sleep. This is not because of the noise from the motor, but because of the noise from your cadence as you jog or run on the treadmill.  

The Console 

The console of the Sunny Health & Fitness SF-T7718SMART Treadmill

This treadmill is equipped with a Bluetooth console that features an LED monitor. The LED monitor has 3 windows that track workout stats such as Distance/Calories, Time/Steps, and Speed/Pulse, respectively. 

To be able to track and observe your heart rate data you must hold a finger on the pulse sensor on the right side of the console. It is not possible to sync a wireless HR chest strap with the treadmill.  

The level of clarity is amazing! No lighting condition in a room can compromise its readability.  

The console also features the Start button, Pause button, Program button, Quick Speed buttons, Mode button, and Gradual Speed Adjustment buttons.  

The pause button allows you to keep the treadmill on standby without turning it off whenever you wish to momentarily step out so that your ongoing workout data won’t be lost.   

As aforementioned, there are 9 built-in or preset workout programs designed specifically for achieving certain fitness goals. Each of the 9 preset programs has 10 segments that have different preset speed levels.  

So, when any of the preset workout programs is selected, a certain speed level will apply automatically to your workout 

There is a countdown goal for Time, Distance, and Calories as well. This function keeps you on your toes by challenging you to push past your limit.  

The console is compatible with the SunnyFIT workout app. As explained earlier in this review, it is designed to avail more fun and productive workout resources.  

The app is available for free on both app stores (Google & Apple). They are compatible with Android and iOS-based smartphones. 

Upon syncing your smartphone with the treadmill via Bluetooth you will be able to track your workout progress in real-time, access and train on virtual trails with real-life locations around the world, use customized workouts and over 100 workout videos, and more.   


The Sunny Health & Fitness SF-T7718SMART Treadmill has a foldable tablet holder that is designated right above the console, and a USB port.  

Therefore, you will be able to place a smartphone/tablet device within a viewing position for entertainment purposes, while the USB port helps you to keep the device charged at all times.  

Just for the record, the USB is designed exclusively for charging only.  

Incline System 

The treadmill does not incorporate an incline system.  


The Sunny Health & Fitness SF-T7718SMART Treadmill folded for storage

The SF-T7718SMART Treadmill is compact, foldable, and transportable which is the perfect recipe for easy storage.  

Once folded, it could be stored under a bed/couch that has a clearance of at least 10’’ underneath, or better still have it leaned vertically against the wall.  

Even though it weighs 118 lbs./53.5 kg, it can easily be moved to and from the storage area via the integrated transport wheels.
