Sunny Health & Fitness SF-T7820 Treadmill Review

Two things are true about the Sunny Health & Fitness SF-T7820 Treadmill, it’s bulky and heavy, so, it will require a little bit of space for workouts. However, it is also true that it’s sturdy and has a decent running-surface area to accommodate users of different heights and sizes.  

The treadmill is integrated with a number of features that could help you to comfortably work out productively. These features include the shock-absorbing system, the large console, the 7’’ LCD backlit monitor, water bottle holders, a tablet holder, etc.  

On the functionality aspect, the treadmill features a 2.5 peak horsepower motor that provides the drive (speed range 0.6-12.6 mph) needed for walking, jogging, and running exercises. There is an automatic incline of 0%-15%, 36 preset programs, 3 custom programs, Body Mass Index function, and more.  

The unit supports 285 pounds/129 kg maximum user weight capacity. 

That said, this treadmill is not a commercial-grade unit, it is designed for home use.

The Frame and Construction 

Sunny Health & Fitness SF-T7820 Treadmill

As aforementioned, the Sunny Health & Fitness SF-T7820 Treadmill is conspicuously bulky and heavy at the same time. The frame is made of a light gray anti-corrosive coated steel frame, while other parts such as the side rails and the motor covers, and part of the console are made of ABS plastic.  

The overall assembled dimensions of this treadmill are 69.5’’ long by 34’’ wide by 60’’ high. Obviously, one of the bulkiest treadmills available.  

So, a workout area with a perimeter of 5’8’’ length by 2’9’’ width will be required for the SF-T7820 Treadmill. And additional extra clearance of 3’ at the rear and 2’ on each side will be necessary for safety and easy-access reasons especially if it’s going to be used in a confined area.  

The ceiling height of the room the unit is to be used should be determined based on your height. For instance, the step-up height of the treadmill is about 10’’ and when the incline is adjusted to its highest, few inches will be gained. So do the math, add the step-up height plus your height plus extra 20’’ to get the recommended ceiling height.  

The side rails are textured and wide enough to allow you to step on them when you are done exercising without having to turn OFF the treadmill. 

The treadmill has a space-saving design that includes a hydraulic cylinder that aids in folding and lowering the deck unassisted with ease. The folded dimensions are 49’’ length by 34’’ width by 60’’ height. This reduces the storage space required for the treadmill and also allows you to access and clean under the deck without hassle.  

Shock-absorbing system of the Sunny Health & Fitness SF-T7820 Treadmill

The deck is equipped with a shock-absorbing system that reduces the stress that is usually felt on the knee joints, the ankles, and the back during a jogging or running activity on a treadmill. 

Also, the running surface is large enough to accommodate most users with spaces to spare around them. The tread belt dimensions are 55’’ length by 19.7’’ width.  

It is important to clarify that this treadmill does not have a cooling fan or speakers/sound system even though the console seems to be integrated with them.  And the console is not telemetry or Bluetooth enabled. This means there is no opportunity to connect online to an app wirelessly or to use an HR chest strap for pulse monitoring.  

However, it does have a set of handrails and a set of EKG heart rate sensors integrated handlebars. These (EKG heart rate sensors) read your heart rate and transmit the data to the display when held during a workout. 

The Motor 

The Sunny Health & Fitness SF-T7820 Treadmill is a motorized treadmill that has a 2.5 peak horsepower motor. The motor is designated at the front base of the treadmill where your foot cannot reach while running and it’s concealed by ABS plastic.  

The motor is strong and powerful enough to provide the drive required for frequent and prolonged running exercise without overheating or breaking down. Its performance is smooth, quiet, and vibration-free, thanks to the included small flywheel that ensure that the tread belt motion is steady.  

The sound of your footfall could be heard more than the actual sound of the treadmill’s operation. Thus, you can exercise without constituting a nuisance around you. Your family or the neighbors won’t be bothered by your activities on the treadmill.  

You may watch your favorite TV show or listen to good music while you walk, jog, or run on the treadmill without having the need to amplify the volume above the normal range.  

The 2.5 peak horsepower motor provides a speed range of 0.6-12.6 mph with an increment of 0.1 mph that allows you to micro-adjust the speed to a tailored suitable speed range that is fine with you.  

The speed adjustment is done via the keys on the console. There are buttons for gradual adjustments and there are buttons for quick adjustments. The gradual buttons allow you to adjust speed by an increment of 0.1 mph as stated above. And by pressing and holding down any of the gradual adjustment buttons, the selection will run fast until it reaches the speed level you desire.  

While on the other hand, the quick speed adjustment buttons are available in 2 mph, 4 mph, 7 mph, and 9 mph. By selecting any of these the speed jumps to the selected speed range.  

Incline System 

The Sunny Health & Fitness SF-T7820 Treadmill has an automatic incline system that could be adjusted from 0%-15%. This typically increases the difficulty by mimicking running uphill. 

Just as the speed, the incline could be adjusted via the gradual and the quick incline buttons on the console. The incline can be adjusted by a 1% increment using the gradual adjustment buttons while the quick incline buttons offer 3, 6, 9, and 12 levels.  

The Console 

The console of the Sunny Health & Fitness SF-T7820 Treadmill

The console on the Sunny Health & Fitness SF-T7820 Treadmill is large and mid-range. It features a 7’’ backlit LCD monitor with segmented windows that display workout stats such as Time, Speed, Distance, Calories Burned, Steps, Heart Rate, and Incline simultaneously.  

The readability is high and can’t be diminished.  

Other features available on the console are the water bottle holders, the tablet holder, the emergency key, speed and incline adjustment buttons, stop and start/pause buttons, mode, and program buttons.  

There are 36 preset programs and 3 custom programs. The preset programs are designed specifically to help you achieve a certain goal. For instance, they are good in muscle toning, weight loss, improvement of cardiovascular health, strength, and endurance.  

And when a certain preset program is selected, an incline level and speed limit are automatically assigned. The custom programs offer the opportunity for you to create and save your own programs.  

The treadmill also has the BMI (Body Mass Index) body fat calculator function that allows you to enter values such as gender, age, height, and weight, so that it will calculate and give you the percentage of your body fat.  

Again, the console is not telemetry or Bluetooth enabled.  


Folded Sunny Health & Fitness SF-T7820 Treadmill

The Sunny Health & Fitness SF-T7820 Treadmill has a space-saving design that enables you to fold it up. The treadmill’s folding mechanism allows you to easily fold it up regardless of its weight and you can unfold it unassisted due to the soft drop system. Therefore, not only does the treadmill unfold without using your hands, it drops gently and slowly to the floor.  

There integrated transport wheels that assist in the relocation process.  

That said, the treadmill will still require a little bit of space for storage. The garage might be the best place for storage.  


As aforementioned, there are built-in water bottle holders that could also serve as accessory holders. These allow you to keep a water bottle handy to stay hydrated and to keep other stuff such as keys, a remote controller, etc.  

There is also a tablet holder for the placement of your tablet device so that you may enjoy browsing, sending emails, watching a movie, listening to music, or taking calls while exercising on the treadmill.
