The SereneLife SLFTRD25 treadmill can be compared in terms of features with the Sunny FA-7967. However, it has online connectivity and is compatible with the FitShow app for online workout history tracking. It’s a fairly decent machine for the price offering plenty of workout programs to choose from and a pretty solid deck.

The SereneLife SLFTRD25 features a steel frame combining oval, rectangular, and cylindrical tubing in its construction. All the steel parts are double-coated with a corrosion-resistant paint finish. The main color used is black, with the exception of the deck frame which is gray; these are the only colors available for this machine at least for the moment.
The treadmill is not too large. With all the parts assembled, it is approx. 54.78″ (139 cm) long, and 26.78″ (68 cm) wide. It is recommended, though, to leave at least two feet of clearance on each side of its deck, and at least three feet of clearance at the rear for safe usage.
The deck has a folding design. This can be a plus not only because it can save you some space when the machine is not in use, it can also be very helpful when you need to clean under the deck. The folding mechanism involved a small hydraulic cylinder which enables the deck to lower slowly to prevent damage when you unfold it.
This SereneLife treadmill is not extremely heavy compared with other models. However, it still weighs approx. 70 lbs (32 kg). Therefore, the transport of the packaged unit should be done by two people. However, once it is assembled, it can be relocated with ease by only one person as its front base bar is equipped with a set of small wheels.
Deck construction and incline
The SereneLife SLFTRD25 treadmill offers a fairly decent running surface of 43.3″L x 15.75″W (110L x 40W cm). This being said, it should be able to accommodate users up to 6’1″ – 6’2″ (185 – 188 cm). Of course, taller users should still be able to use this machine but they may not be able to benefit from a complete range of motion during running. Also, the deck is rated for a maximum user weight limit of 265 lbs (120 kg).
The belt is multi-layered with its top layer made of thick rubber material with a textured surface for an improved grip. The internal rollers that move the belt integrate high-grade sealed bearings for a smooth motion. They are also crowned for improved traction and to prolong the belt’s lifespan.
Although the deck doesn’t have extra-large shock absorption elements as is the case for the Nautilus T618, for example, it does integrate several small cushions to reduce impact. Also, the deck board has a bit of flex itself. Thus, a run or walk on this treadmill will generate considerably less impact on your joints, and implicitly less workout-related joint and back pain.
The SereneLife SLFTRD25 treadmill is equipped with a manual incline system. This being said, you cannot adjust the incline as you walk or run on the treadmill. Also, the console cannot automatically adjust the incline.
The unit’s incline system consists of two adjustable “feet” placed at the rear of the deck. They have three adjustment positions each. You can lock them in the desired position via a removable metallic pin. The three adjustment positions of the incline are 1.5°, 2.5°, and 3.5°. This being said, on the first position available, the deck is not perfectly horizontal. Although this shouldn’t affect your workout much, it still adds a bit of difficulty to the ride.
The deck step-up height is approx. 6.5 (17 cm) when the rear stabilizers are unfolded (or locked in the highest position). Therefore, to avoid any inconveniences, it is recommended to use this treadmill in a room with a ceiling that is at least 10″ (25 cm) higher than the height of the tallest user.
The SereneLife SLFTRD25 is equipped with a 1.5 HP motor. Although this is not exactly the most powerful treadmill motor, it still offers the possibility to run for a fairly long period of time without overheating. It is recommended, though, to pause your treadmill and let is rest for at least 10-20 minutes after every few hours of use.
This SereneLife treadmill offers a speed range between 0.6 MPH and 7.5 MPH. The speed adjustment increments are 0.1 MPH. There are controls for gradual speed adjustment on the console and integrated into the right handgrip of the machine. The console is also equipped with quick selection speed controls for 2 MPH, 3 MPH, 4 MPH, 5 MPH, and 6 MPH. Therefore, if you adjust the speed from one of these buttons, the belt will gradually increase or decrease speed until it reaches the selected speed setting.
Since the treadmill’s motor is not super powerful and only offers a peak output of 1.6 HP, its power consumption is also minimal. This being said, even if you will be using it daily, it shouldn’t add more than a few dollars to the electricity bill. Also, the motor itself doesn’t generate a lot of noise when in use, but depending on how fast you go, your cadence may generate more or less noise.
The SereneLife SLFTRD25 treadmill is equipped with a mid-range console. To begin with, it features an LCD display with blue LED backlight for improved readability. The display is divided into 5 sub-sections in order to show multiple workout metrics at once. It tracks time, speed, distance, calories, and pulse. Speed and distance are shown in MPH and miles. The pulse reading function is grip contact only. In other words, the console cannot read your pulse from a wireless device.
The console makes available 16 pre-set workout programs. Each program has its segment layout engraved on the console. Some feature an interval layout, others gradually increase speed up to a certain level, then gradually decrease it up to the end of the program, while others focus on helping you burn more calories. Of course, there is also the Manual mode which offers the possibility to adjust the speed as you like throughout your workout. You can also select workout targets for time, distance, and calories burned.
The console is Bluetooth enabled. It is compatible with the FitShow app. Therefore, if you install this app on your smartphone, you should be able to track your workout history and progress online, along with several other features.
The console offers several other notable features. Among them, we can count the sound system, the USB port, the SD card port, the device holder, and the accessory holders. The sound system consists of two small speakers integrated at the bottom of the console. There is an AUX port for connecting your device to the console in order to listen to your music through the integrated speakers. They’re not super powerful but they do offer better sound quality than the integrated speakers of a smartphone or tablet.
The USB port offers the possibility to charge your device as you exercise. The device holder consists of a small shelf integrated above the speakers. It can serve as support for any smartphone or tablet. And finally, the accessory holders are moulded into the dashboard of the console, one on each side; they are large enough to hold a hydration bottle or other accessories that you might need to have at hand as you exercise.
Assembly and Maintenance
The machine’s deck with the motor, the rollers, and the belt comes pre-assembled. You only need to attach the two upright bars and the console with the handlebars. This shouldn’t take more than 30-40 minutes. The manual provides clear assembly instructions and all the necessary tools are included.
Once the machine is assembled, maintenance doesn’t require much. The deck needs to be lubricated periodically with treadmill lubricant. The belt should be kept clean to prevent any debris or textile fibers to be caught in the motor. Other than this, it is also recommended to periodically inspect the machine to make sure that everything works accordingly.
