SLFTRD25 Frame Construction

The SereneLife SLFTRD25 treadmill features a steel frame combining oval, rectangular, and cylindrical tubing in its construction. In addition, all the steel parts come double-coated with a corrosion-resistant black paint finish, except for the deck frame, which is gray.

SereneLife SLFTRD25 Treadmill

The treadmill is not too large. With all the parts assembled, it is approximately 54.78″ (139 cm) long and 26.78″ (68 cm) wide. It is advisable to leave at least two clearance feet on each side of its deck and at least three clearance feet at the rear for safe usage.

The deck has a folding design, which is a plus because it can save you some space when the machine is not in use, but it can also be beneficial when you need to clean under the deck. The folding mechanism involves a small hydraulic cylinder that lets the deck lower slowly to prevent damage when unfolding it.

This SereneLife treadmill is not extremely heavy compared with other models. However, it still weighs approx—70 lbs (32 kg). Therefore, two people should carry the packaged unit. However, once assembled, it is easily relocated by only one person as its front base bar comes equipped with small wheels.

Deck construction and incline

The SereneLife SLFTRD25 treadmill offers a reasonably decent running surface of 43.3″L x 15.75″W (110L x 40W cm). Thus, it should accommodate users up to 6’1″ – 6’2″ (185 – 188 cm).

Of course, taller users may still use this machine, but they may not benefit from a complete range of motion during running. Also, the deck has a maximum user weight capacity of 265 lbs (120 kg).

The belt is multi-layered with its thick rubber material top layer with a textured surface for an improved grip. The internal rollers that move the belt integrate high-grade sealed bearings smoothly. They are also crowned for enhanced traction and prolong the belt’s lifespan.

Although the deck doesn’t have extra-large shock absorption elements, it does integrate several small cushions to reduce impact. Also, the deck board has a bit of flex itself. Thus, a jog or walk on this treadmill will significantly less affect your joints and less workout-related joint and back pain.

The SereneLife SLFTRD25 treadmill comes equipped with a manual incline system. Therefore, you cannot adjust the incline as you walk or jog on the treadmill. Also, the console cannot automatically adjust the incline.

The unit’s incline system consists of two adjustable “feet” at the rear of the deck. They have three adjustment positions each. Therefore, you can lock them in the desired position via a removable metallic pin.

There are three incline positions available. These are 1.5°, 2.5°, and 3.5°. Thus, on the first option, the deck is not perfectly horizontal. Although this shouldn’t affect your workout much, it still adds difficulty to the training.

The step-up deck height is approx. 6.5 (17 cm) when the rear stabilizers are unfolded (or locked in the highest position). Therefore, using this treadmill in a room with a ceiling at least 10″ (25 cm) higher than the tallest user’s height is advisable.

SFLTRD25 Drive motor

The SereneLife SLFTRD25 treadmill comes equipped with a 1.5 HP motor. Although this is not the most potent treadmill motor, it still allows you to jog without overheating for a relatively long time. Therefore, it is advisable to pause your treadmill and let it 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. In addition, there are controls for gradual speed adjustment on the console and integrated into the machine’s right handgrip.

The console also comes 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 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 minimal. Therefore, even if you use it daily, it shouldn’t add more than a few dollars to the electricity bill.

Also, the motor doesn’t generate much noise when used, but your cadence may create more or less noise depending on how fast you go.


The SereneLife SLFTRD25 treadmill comes equipped with a mid-range console. To begin with, it features an LCD with a blue LED backlight for improved readability. In addition, the display divides into five sub-sections to show multiple workout metrics at once.

It tracks time, speed, distance, calories, and pulse—the speed and distance displayed in MPH and miles. Unfortunately, the pulse reading function is handgrip only. Therefore, the console cannot read your pulse from a wireless device.

The console makes available 16 preset workout programs. Each program has its segment layout engraved on the console. Some feature an interval layout; others gradually increase speed to a certain level, then gradually decrease it to the program’s end. In contrast, others focus on helping you burn more calories.

Of course, there is also the Manual mode, which can adjust the speed you like throughout your workout. You can also select workout targets for time, distance, and calories burned.

The console is Bluetooth-enabled. In addition, it is compatible with the FitShow app. Therefore, if you install this app on your smartphone, you should track your workout history and progress online, along with several other features.

The console offers several other notable features. Among them, I 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.

It comes equipped with an AUX port to connect devices to the console. Thus, you can listen to your music through the integrated speakers. They’re not super powerful, but they offer better sound quality than the integrated speakers of smartphones or tablets.

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 come molded into the console’s dashboard, one on each side; they are large enough to hold a hydration bottle or other accessories you might need to exercise.

SLFTRD25 Assembly and Maintenance

The machine’s deck with the motor, the rollers, and the belt comes pre-assembled. Next, you only need to attach the handlebars, two upright bars, and the console.

Consequently, it shouldn’t take more than 30-40 minutes. In addition, the manual provides clear assembly instructions, and all the necessary tools come with the machine.

Once assembled, maintenance doesn’t require much. The deck needs lubricating periodically with treadmill lubricant. It would help clean the belt to prevent debris or textile fibers from being caught in the motor. It would also help regularly inspect the machine to ensure everything works accordingly.

  1. I have been having some issues with my knee lately. It starts to hurt. So I have stopped using my bike. But I feel I still need to walk. And because of how things are currently in my town, I’ll have to remain at home. That’s how I decided that multifunctional jogging and walking machines were for me. Thanks for this review.

    • Hi Abel, you’re welcome. Let me know if I can be of any assistance. I’m always happy to help.

      Best regards, Robert

  2. Hi Robert 

    This SereneLife SLFTRD25 is an excellent treadmill. I am always on the lookout for improved fitness gear for several reasons. First, I am an avid cyclist, so I like to vary my workouts. The other is that I train clients in my gym at home. Therefore, it is imperative to me that I have great sturdy gear.

    The SereneLife SLFTRD25 impresses me also that it comes with its assembly tools and clear instructions. A recent piece of equipment I purchased had no tools, and the instructions were in a foreign language! In addition, the console data is fantastic as I like to keep records of my client’s progress. Thank you immensely.


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

      Kind regards, Robert

  3. Hi Robert, thank you for this fantastic review on the SereneLife SLFTRD25 treadmill! I’ve been thinking of getting a treadmill as it’s the middle of winter in Calgary, and I need to run to stay fit. Unfortunately, I don’t believe the SereneLife SLFTRD25 fits my needs. I need something with higher top speeds, and it would be ideal if I had an interactive screen to watch things on. Do you have any recommendations for treadmills that fit these specifications?

    • Hi Kevin, thanks for stopping by and sharing your thoughts with us. I don’t know your budget, but let’s start with the Bowflex Treadmill 22. Would you take a look and let me know what you think?

      There are many excellent treadmills. I have over 100 treadmills reviewed, so if you could narrow down your requirements and budget, I’m sure I can find something for you.

      Please let me know if I may further assist you with exercise equipment. I’m always happy to help.

      Kind regards, Robert
