SF-T7718 Frame Construction

Sunny SF-T7718 SMART Folding Treadmill

The Sunny SF-T7718 SMART folding treadmill features a rectangular tubing steel frame. Of course, the machine also integrates several plastic parts. The most notable ones are the motor cover, the side rail covers, the console casing, and the handrails. These are all various durable thermoplastic polymers.

This Sunny Health & Fitness treadmill is a fitness machine made for home use, so it’s not very large. With all the parts assembled, it is approx—63.6″ (162 cm) long and 29.3″ (74 cm) wide. However, even though it doesn’t take up too much floor space, it is still advisable to leave at least three feet of clearance at the rear of the deck and at least two feet at the front and on each side of the machine.

In addition, the treadmill has a folding design. With its two supporting bars, the console can fold down over the deck. In the folded position, its height is only 8.3″ (21 cm), so you can store it under a couch or bed if there is a clearance of at least 8.5″ (22 cm) underneath it. The machine can also store vertically against a wall.

Since it’s a small treadmill, it is not super heavy, weighing approx—118 lbs (53 kg). Therefore, two people should carry and assemble the machine. But once removed from its box, one person can quickly move it as its front base frame features transport wheels. In addition, the rear base of the deck features adjustable levelers.

Deck Construction

Unfortunately, the Sunny SF-T7718 SMART folding treadmill does not have an incline system. Thus, you cannot change the angle of the deck in any way. The running surface is almost perfectly horizontal and has a shallow profile. In addition, the belt is approx. 3″ (8 cm) above the floor levels, so you don’t have to worry about ceiling height issues.

The treadmill’s running surface is not the largest. It is 47″ (119 cm) long and 20″ (51 cm) wide. Therefore, the Sunny SF-T7718 SMART treadmill may not be the best choice for users taller than 6’1″ (185 cm), at least not for running. However, for walking workouts, it should suffice even for taller users. The deck has a maximum user weight limit of 250 lbs (113 kg).

The machine has a cushioned deck. It has two large external cushions, one visible on each side of the deck. However, it also integrates several smaller rubber cushions and pads. Furthermore, the deck board has a bit of flex, so the machine’s running platform delivers a more comfortable run or walks than the same type of workout on asphalt or concrete.

The multi-layered tread belt’s top layer features a textured, rubberized surface to provide a superior grip for any running footwear. The bottom layer sticks better to the rollers to eliminate belt slippage. However, the exact size of the machine’s rollers is not specified. In addition, they have tapering to provide better traction for the belt and to prolong its lifespan. Furthermore, they also integrate high-grade sealed bearings.

SF-T7718 Drive motor

This Sunny SF-T7718 SMART folding treadmill is electric. Thus, you’ll need to connect it to a power source. It comes with a power cable featuring a U.S. standard plug. The connector for the cable is at the front of the machine, next to the On/Off switch.

The treadmill has a 2.5 HP peak power motor. Its continuous duty is approx. 1.25 CHP. Unfortunately, it’s not the most potent treadmill motor, but it should withstand prolonged runs without losing performance or overheating. Furthermore, the manual advises that you should turn off the machine for 10 minutes after every two hours of continuous use.

The motor’s default speed is 0.6 MPH. Its maximum speed is 9.0 MPH. In addition, the console has buttons for gradual speed adjustment and preset speed buttons for 3 MPH and 6 MPH. The speed adjustment increments are 0.1 MPH. Also, the console has several workout programs that automatically adjust the speed.

The motor doesn’t create too much noise even if you set the speed up to 9 MPH. However, your cadence may generate more or less noise depending on weight, footwear, running form, floor structure, and other factors. Therefore, even if the motor is quiet, other persons in the household may still hear you using the treadmill.


Sunny SF-T7718 SMART Folding Treadmill

The Sunny SF-T7718 SMART folding treadmill has an LED display console featuring three windows that indicate distance/calories, time/steps, and speed/pulse. The speed and distance are in imperial units (MPH and miles). However, there is no option for setting them to metric units.

The pulse reading function consists of a sensor on the console’s right side. So, to have your pulse read by the console, you must hold your finger on it for a few seconds. Unfortunately, the console cannot read your pulse from a wireless heart rate chest strap.

The console has nine preset workout programs in its memory (P1 – P9). Each program has ten workout segments and a different speed setting for each segment. The default duration of each program is 10 minutes, but you can adjust this setting.

In addition, workout target functions are available for time, distance, and calories. After choosing a workout target, the console will count down from the selected target until it reaches zero. For instance, this function can help you push your limits from one workout session to another.

The console has Bluetooth connectivity and is compatible with the SunnyFit app. The app is free for iOS and Android; you can download it from the Apple app store or Google Play. The app offers several features: scenic rides based on locations worldwide, workout videos, challenges, and a live sync with the console. Therefore, you can view the current miles traveled, speed, and calories burned on the app interface on your phone or tablet.

Among other notable console features, I count a device holder and a USB port. The device holder is at the top of the console and is foldable. The USB port is for device charging only. However, you cannot stream workout data through it.

SF-T7718 Assembly and Maintenance

Sunny SF-T7718 SMART Folding Treadmill

One of the best aspects of the Sunny SF-T7718 SMART folding treadmill is that it comes completely assembled. Remove it from the box, unfold it, and plug it in. Consequently, this shouldn’t take much of your time. In addition, the manual provides clear instructions for its usage.

For maintenance, the belt requires periodic lubrication, and a bottle of lubricant comes with the treadmill. The manual provides instructions on how and when to lubricate the belt. Other than this, you must keep the machine clean and check that the nuts and bolts remain tight and held in place.

  1. I found this very interesting I have never heard of an extra-wide treadmill before. But I have a compactable treadmill at home- I like it, and it’s great for those who don’t have much space in their house. But unfortunately, it doesn’t have an incline feature; I feel like Iike having the option to add an incline to get a bit more of a workout is essential.

  2. Hi Robert 

    This Sunny Health & Fitness treadmill looks like a perfect machine for our holiday home or even our city apartment. I am not that fussed about the incline as I do not hill run anyway. The sleek design is also great and is lower to the floor. It would be a fantastic machine for beginners dealing with their balance performance. 

    The folding and vertical storage options are excellent, also. Thinking I’ll check out the reviews and go from there. Excellent read!

  3. I am excited to see a treadmill lowered to the floor. It is the guarantee of balance and will give one confidence when running. For me, the top is a light weight of 113kg, and the magical console with nine programs. And like you said, it also comes with three years guarantee. Thank you for coming up with another supermachine for fitness.

  4. A foldable treadmill is ideal for anybody who lives in a small space or wants to store the treadmill when it is not in use. I have not seen an extra wide treadmill, so this is an exciting feature. 

    I love that the Sunny SF-T7718 SMART folding treadmill is fully assembled, so you won’t need to try and assemble the treadmill if you are on your own. In addition, with Bluetooth connectivity and nine preset programs, the treadmill caters to different fitness levels. 

    The only drawback for me is that there is no incline if you are training for different terrains—otherwise a great addition to a home gym.
