For instance, the fronts of the side rails are made up of ABS and have a rubber layer on top to forestall foot slippage. Furthermore, the engine cover and the front dashboard that joins the control center are also made of ABS material.

It requires a minimum of 2 persons for the first time assembly, and once done, it becomes easier to shift from one place to another with the help of an equipped transportation wheel.

One more plus point about this treadmill is its excellent folding design which helps you lock the deck when not used. You can lock the deck in an upright position and save more space.

Furnished with a motorized incline framework, the Sunny SF-T7874 treadmill can be adjusted from the console. Apart from this, you can also control the incline from the left handlebar section.

Never forget to connect to power when you want to adjust the incline. As the unit’s incline framework has a small size motor and lifts which is placed under the deck’s front part, it elevates slowly when you try to adjust the incline.

The incline can be incremented by 1%, and the ranges provided for incline are from 0% to 15%. You can also choose between 5%, 10%, or 15% for quick and easy selection.

Step-up Height

The step-up height of SF-T7874 is approximately 9’’ (23 cm) with a maximum incline of a few more inches in its front.

Please note that you can get speed and distance either in Imperial or Metric units. However, the console can’t be connected online or connect to any Bluetooth. It is also not telemetric so that you can read the pulse without the help of a wire. To know your pulse rate, you have to use equipped sensors in the front handlebars of the unit.

The Sunny SF-T7874 offers 14 pre-set, 3 custom, and 1 manual workout option so that you can train yourself to stay at your place. The manual program starts the treadmill and adjusts the incline speed as per your choice throughout the training session.

Another best thing about the treadmill is, it can major your BMI, and all you have to do is input your age, gender, weight, and height to the machine.

The package includes every essential kit along with a manual on how to assemble the unit, and you can assemble the entire unit in less than half an hour.


When it comes to the maintenance of the treadmill, people think it will cost them more compared to the purchase price. But the truth is, this treadmill requires only a bottle of lubricant to grease the belts regularly for smooth use. You will also get an instruction manual to use the lubricant.

Apart from lubrication, another concern about treadmills is to keep the running belt dirt-free and restrain it from textile fibers and small objects that can harm the unit.

So, you have to clean the running belt regularly and intermittently examine the unit for free or harmed parts to re-fix or supplant them before mishaps occur.
