The treadmill shimmers the high-quality construct, along with a low-price tag peculiar to its manufacturer.

Also called the SLFTRD20, this device comes in a sleek, foldable, compact, space-saving design alongside a sturdy, high-quality frame. Overall, its features are similar to the Smart Digital Treadmill. Only that its deck is wider, and it comes with a manual incline system.

What’s the price?

Particularly, this treadmill is ideal for walking, jogging, and running at a slow speed. It comes with twelve preset workout programs that fit many fitness goals. It features an easily operated LCD screen and a powerful but quiet motor.

Some Unique Features Of The SLFTRD20

  • Frame and Deck: The running belt of this treadmill is 39.37 inches long and 15.74 inches wide. This extended deck provides extra space for larger persons to run comfortably. More so, the device has a rated maximum user weight of 265 pounds- 45 extra pounds than the 220lbs most competitors provide.

The device frame of the SereneLife SLFTRD20 is made of high-quality steel and is 60 pounds in weight. There are also two transportation wheels on its base for easy movement.

  • Motor: this treadmill has a 1Hp rated motor to run its belt at speeds between 0.6 – 6MpH. Although fairly high in power, the motor is quiet in operation and does not vibrate. As such, it allows users to workout at any time without disturbing anyone. It is worth mentioning that this motor is not suitable for commercial purposes. As frequent, repeated daily use can overwork its component. However, it is perfect for home use.
  • Console: this device comes with an LCD screen with touch buttons that displays the distance covered, speed, calories burnt, and pulse. Like other SereneLife treadmills, its console has large, easily read digits with a superb backlight.

From the console, users can increase or decrease speeds by 0.5MpH or quickly select a speed of either 2, 3, 4, 5, or 6MPH.

  • Safety tool: There are two safety options available on this machine. First is the emergency stop button on the console that immediately stops the device when pushed. Also, the equipment features a built-in safety key that is attached to the runner. If the safety key stretches more than its preset limit, the belt will automatically halt at a rapid rate.

Other Features

  • Incline: unlike its predecessors, this device features a three-position manual incline system. These incline levels allow users to set the deck at an elevation of 15 degrees to increase exercise intensity and burn calories faster.
  • Folding capacity: It is common for foldable treadmills to be hard to collapse or unfold. However, this machine does not fall into that category of machines- thanks to its Soft Drop hydraulic mechanism. This option gently lowers the deck and collapses the machineeffortlessly.

Specifically, the treadmill’s open dimension is 25.2 x 24.0 x 49.2 inches (L x W x H). But after folding, it measures only 50.8x 24.0 x 49.2 inches.

  • Heart rate monitoring: this treadmill comes with sensors on its handlebars. These sensors are responsible for BPM pulse monitoring, and upon grip, it will display the user’s heart rate on the machine’s console.
  • Sports App connection: The machine allows users to connect the iFitShow app from phones (Android or iOS), tablet, or PC to the treadmill. With that, users can record and review training data, display fitness stats, and share these data on social media. The connection is possible because of the treadmill allows Bluetooth connectivity. However, this connection limits only to the app and does not allow music or any other form of entertainment.
  • Accessories: There are two cup holders on the machine, along with a detachable tablet or book holder.
