The Sunny SF-T7874 features a durable steel frame, but it also 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 ABS material.
The fully assembled unit is fairly large. 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 in an upright position, 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 is 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 used 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 some 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 a lift placed 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.
The motor of the Sunny SF-T7874 delivers a peak power of 3.0 HP. It’s a mid-range motor that incorporates a small flywheel to minimize vibration and promote a smooth movement for the belt.
The machine’s drive motor offers a speed range between 0.6 MPH 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, giving you the possibility to find the exact speed that fits your pace and stride.
The console comes with controls for 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.
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 divide into 20 segments, and each segment has 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, and for each of them, 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, 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, all you have to do is 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.
