SF-T7874 Frame Construction

Sunny SF-T7874 Performance Treadmill

The Sunny SF-T7874 features a durable steel frame but integrates several ABS parts. For example, the covers of the side rails are ABS made and have a rubberized layer on top to prevent foot slippage. In addition, the motor cover and the front dashboard that incorporates the console are made of ABS material.

The fully assembled unit is pretty significant. It takes approx—70″L x 31″W (178 x 79 cm) of floor space. Plus, you should allow at least two feet of clearance on each side of the unit and at least three feet at the rear of the deck for safe usage and easy access.

Also, with the deck folded up, the unit’s length reduces to 45″ (114 cm), while its height reaches approx — 62″ (157 cm).

Compared to other treadmills, the SF-T7874 isn’t extremely heavy. But it still weighs approx. 153 lbs (~69 kg). Therefore, two people should transport and unbox the machine. Conversely, once assembled, its relocation is via the bases that come with wheels.

The SF-T7874 also has a folding design. Thus, it is quite a plus because you can save space while the unit is not in use, lock the deck upright, and easily vacuum under it. In addition, its folding mechanism involves a hydraulic cylinder that delivers a “soft drop” when you unfold the deck, preventing it from falling and sustaining damage.

I have to mention one last aspect the unit’s paint finish. The Sunny SF-T7874 features a durable powder coating on all its metallic parts, resistant to corrosion and abrasion. The color is light-gray, with the “Sunny” logo painted red.


The machine’s deck has a maximum user weight capacity of 285 lbs (130 kg). It uses a non-slip belt which provides a running surface of 54″L x 18″W (137 x 46 cm). Thus, the treadmill comfortably accommodates users up to 6’0″ (183 cm), allowing a complete stride.

The deck integrates two cushioning elements closer to the front to alleviate shock generated during each foot strike. Therefore, running on this treadmill should reduce workout-related pain more than running on asphalt or concrete.

SF-T7874 Incline and step-up height

The Sunny Health & Fitness SF-T7874 treadmill comes with a motorized incline system. Therefore, you can only adjust its incline from the console or the controls integrated into its left handlebar. The machine requires a connection to a power source to operate these features. Also, specific programs auto-adjust the incline throughout their duration.

The machine’s incline system consists of a small motor and lifts under the deck’s front part. As you adjust the incline, the front of the deck will slowly elevate. It provides an incline range between 0% and 15%, the incline increments being 1%.

The console offers controls for gradual incline adjustment, but they’re also keys to quickly selecting the 5%, 10%, and 15% incline.

The step-up height of the running platform is approximately 9″ (23 cm). Also, the maximum incline elevates its front part by at least a few extra inches. Therefore, make sure that the ceiling height in the room where you will be using the machine is at least 22″-23″ (56-58 cm) higher than the tallest user to avoid any issues.

Drive motor

The motor of the Sunny SF-T7874 delivers a peak power of 3.0 HP. It’s a mid-range motor incorporates a small flywheel to minimize vibration and promote smooth movement for the belt.

The machine’s drive motor offers a speed range between 0.6 and 11 MPH. Depending on the console’s setup, the adjustment increments are 0.1 MPH or 0.1 km/h. Thus, the machine offers excellent micro-adjustment, allowing you to find the exact speed that fits your pace and stride.

The console controls gradual speed adjustment, but they’re also quick selection controls for 3 MPH, 6 MPH, and 9 MPH. The right handlebar also features controls for gradual speed adjustment.

SF-T7874 Console

This Sunny treadmill comes with a mid-range programmable console. It does not have Bluetooth or online capabilities but does offer plenty of workout programs and other features to keep you motivated.

The console features a 7-inch LCD with an LED backlight and significant digits to provide superior readability. It monitors time, distance, calories burned, pulse, speed, and incline. It also shows the grid with the profiles of the workout program in use.

You can select either Metric units or Imperial units for speed and distance. For pulse reading, you must use the sensors integrated into the front handlebars of the machine. The console is not telemetric and cannot read your pulse through a wireless HR chest strap transmitter.

The Sunny SF-T7874 treadmill offers one manual program, 14 preset, and three customized workout programs. The Manual program allows you to start the machine and adjust the speed and incline throughout your workout sessions.

The preset programs are divided into 20 segments, each with a duration of 1/20 of the set time. The default timer of each program is 30 minutes, but you can always change it. In addition, the preset programs auto-adjust both the speed and the deck’s incline, depending on the current segment.

The console offers three user profiles; for each, the user can set up their gender, age, height, and weight. They can also create a custom program with specific incline, speed, and duration settings, save it, and re-use it any time they want.

There is also a BMI function (Body Fat Calculator). The machine can calculate your Body Fat Index based on your data (age, gender, height, and weight). Therefore, you can keep better track of your progress.


In terms of non-fitness features, there are only two notable ones. These are the integrated sound system and bottle holders. The sound system consists of two speakers placed on each LCD side.

This sound system is compatible with most MP3 players, smartphones, or tablets. In addition, there is an audio 3.5 mm aux port to connect your device and play your music through the incorporated speakers. And finally, the two bottle holders are cylindrical and large enough to accommodate most hydration bottles.

SF-T7874 Assembly and Maintenance

Like many other treadmills, the machine’s deck with its motors, belt, rollers, and other parts comes pre-assembled. Then, you must attach the two front masts, the console, and several other small covers.

Therefore, it shouldn’t take more than 30 minutes of your time. In addition, all the necessary tools required come with the treadmill, and the manual provides precise assembly instructions.

For maintenance, the belt requires periodic lubrication. It also needs to be lubricated before the first use. A bottle of lubricant comes with the machine, and the manual provides all the instructions for this task.

In addition, it is advisable to keep the running belt clean to prevent any small objects, textile fibers, or dirt from being dragged into the motor. And finally, you should also periodically inspect the unit for loose or damaged parts to re-tighten or replace them before accidents happen.

  1. Sunny Health & Fitness Performance SF-T7874 Treadmill with 11 MPH is very usable and having all the required features needed during exercise.  It is for those who are living in cities and don’t have time to go outside. It helps in reducing weight and improve stamina. 

    This post is well written. I will share it with my friends to help them remain fit and healthy.

    Thank you


  2. I’ve been on the lookout for a durable and sturdy treadmill under $1000, and this is a great find! When checking on Amazon, they charge $89 for assembly, which is much better for me than assembling it myself. I also saw a slightly older model SF-T7873, which is $100 lesser cost, and the features for both appear quite similar. Please clarify, in what way is the SF-T7874 superior to the older SF-T7873? 

    • Hi, thanks for your interest in the Sunny SF-T7874 Performance Treadmill. The most significant differences between the two models are the SF-T7874 has a 3.0 peak HP motor and a 7″ LCD monitor. The SF-T7873 has a 2.5 peak HP motor and a 5″ monitor. I hope this answers your question.

      Happy Holidays!

  3. I’ve never been a fan of treadmills, but I started taking notice when the pandemic hit last year. All along, I’ve always preferred doing my jogging outdoors. This treadmill looks classy, handy, and well worth the money. Once I move to a more spacious home, I’ll no doubt acquire one. Sometimes I do miss my scheduled runs due to getting home late from work. A treadmill will sure do away with that.

    • Hi Steve, thanks for stopping by. Sometimes work, or the weather gets in the way of outdoor exercising. So I like the convenience of having exercise equipment at home. 

      If you’d like some more suggestions to consider, would you please let me know? I’d be happy to help.

      Kind regards, Robert

  4. I’ve heard about this Sunny Treadmill but had no idea it was this powerful, and it has fifteen levels of the automatic incline. That’s awesome. Plus, the pulse grips are a fantastic feature. Then you throw the display screen and tracking components in, and you’ve got a machine and partner to absolutely challenge your endurance. I’m also glad you mentioned the powder coating on the metallic parts. A lot of treadmills tend to erode in certain areas. The fact that this included resisting abrasion is just another plus – I love it! Thank you for sharing this.

    • Hi Rod, thanks for stopping by. Do you have any exercise equipment at home? If not, are you interested in having a home gym? I’d be happy to give you some suggestions to get you started. Would you please let me know? I’d be happy to help.

      Kind regards, Robert

  5. I’ve always loved going to the gym and using the treadmills, mainly to keep my weight down. But once the gyms closed during the pandemic, it disrupted my ability to work out. So I’ve been on the lookout for a treadmill for my home. That way, I can get my cardio in anytime I like. 

    Your review of the Sunny treadmill looks like it could be just perfect for me. I like that this one folds and has so many options, preset modes, and handrail controls. It also seems straightforward to assemble, which is a bonus for me. This seems like good value for the price based on all it offers. I will be putting this one on my shopping list. Thanks for sharing all of these insights.

    • Hi Lee, thanks for stopping by and sharing your thoughts with us. Please let me know if I may further assist you with exercise equipment. I’m always happy to help.

      Kind regards, Robert
