First and foremost, the SF-T7718 model from Sunny Health & Fitness is one of their latest treadmill creations released in the market.

The primary benefit of purchasing this unit is that it occupies minimal floor space and can be folded and stored away.

Being a lightweight capacity machine, it is recommended to use the treadmill primarily for walking and jogging as the maximum speed possible on the unit is not more than 9.0 MPH.

There is no possibility of an inclination, and the motor power is 1.25 CHP.

On the whole, this is a piece of equipment that’s perfect for home gym use as it is affordable, space-saving and even comes with secondary features such as a sound system and a tablet holder.

Frame and Construction

Do you lack sufficient space? Don’t worry about setting up a home gym, as the SF-T7718 treadmill comes with a space-saving design that enables us to fold the unit and store it in small spaces.

We can fold the side grip up to the deck as a result, the unit’s overall height is not more than 7.25 inches. So, it is no wonder that the treadmill could slide under the belt if the available height is above 7.5 inches.

Besides this, it’s also possible to store the unit vertically or move it around using the transport wheels provided. These wheels could also be used as vertical stabilizers.

The treadmill occupies only 63″ in length and  29.5″ in width (160 x 75 cm), while its height is only 48 inches.

I don’t have any second thoughts about the machine’s sturdiness as the frame is made of steel, while the motor, side rails, and console masts come with ABS covers.

A lightweight model, the treadmill still weighs around 117 lbs (53 kg) that guaranteed optimal stability of the fitness equipment.

For better stability, the manufacturer has provided a pair of adjustable levelers on the rear side, and the front side stands solid on rubber pads.

Coming to the deck, it is surprising that such a lightweight treadmill has an optimally durable deck and can hold a maximum user weight capacity of up to 250 lbs (113 kg).

If there are any concerns regarding joint or knee pain, don’t worry about any, as the company has done a splendid job providing two shock absorbers on either side of the deck.

So, jog or walk on the machine at peace without having to worry about knee pain or joint problems.

Running Area

The SF-T7718’s running area measures 46 inches in length and 20 inches in width, which provides a generous area for walking and jogging.

Even though the treadmill can deliver a maximum speed of up to 9 MPH, the running area might be uncomfortable for those individuals above 6 feet in height.

Hence, the SF-T7718 is generally recommended for those individuals who prefer to walk or jog.

Another primary reason this treadmill isn’t quite suitable for running is mainly because of its belt length—running treadmills generally have a 60-inch length, while this model has only a 46-inch length.


The Sunny Health & Fitness SF-T7718 treadmill doesn’t come with an incline system, and hence, it is impossible to make your workout routine quite challenging without any inclination.

Step-up Height

The step-up height of the walking surface is only 3 inches (8 cm)  and hence, has a very low profile.

So, even if the room has a low ceiling height, there isn’t any danger of hitting the ceiling while working out on the machine.

Motor and speed

For an electric treadmill, it is possible to make use of the SF-T7718 machine only when it is connected to a power supply.

The machine comes fitted with a 2.5 HP peak Power (1.25 CHP), making it better for walking or jogging.

Such average motor power also makes it advantageous concerning power consumption—the unit consumes very little power.

Also, the motor is good enough to withstand use by individuals weighing up to 250 lbs (113 kg).

Another major advantage of the motor is that it never succumbs to overheating or loses its performance quality even when used for longer hours.

The speed range possible on the SF-T7718 is between 0.6 MPH and 9.0MPH, and this could be changed using the console.

Make changes to speed using the + and – keys for adjusting the speed gradually. For quick speed changes (3 MPH and 6 MPH), use the keys on the left side of the console.

Figure out the right pace for working out using the 0.1MPH speed increments and set the intensity right for achieving fitness goals.

Such minute adjustments help us make smooth and gradual adjustments getting the correct pace and stride.

Working out at home is a boon for us, but it should never be a bane for others. The manufacturer has understood this well and hence, the machine’s motor is almost noiseless when you are walking.

But, while running, the noise is heard but could be easily overpowered by the sound of music.


We work out to become fitter, lose weight, or stay healthy. It is possible to monitor our fitness progress only when the piece of fitness equipment comes fitted with an optimal console.

The treadmill has a LED display and has three individual windows, each of which tracks various metric details.

Track the distance covered (in miles) and the calories burned from the leftmost window, get details about the time spent working out on the treadmill and the step count from the middle window, and, finally, the right window gives details about pulse and speed (available in MPH).

Get to monitor heart rate details using the contact sensor present on the right side of the console. Still, getting to know the pulse using a Polar HR chest strap is not possible as the console is not telemetric.

We set to work out with a definite target in mind, and if you have any such fitness-related goals, the SF-T7118 treadmill helps you achieve them using the goal settings option provided by the manufacturer.

Set a goal for any of the values such as time, calories burned, and distance covered, and once set, the console counts back until zero to help complete the goal.

To make the workout routine interesting and challenging, 9 different built-in programs (P1-P9) are available. All of them are interval-based routines using different speed settings.

There are 10 intervals/sections in all of these programs, and once you pick your desired exercise duration, every interval continues for a 10th of that selected duration.

It is possible to select any of these programs at a speed of 1.2 MPH or 1.8 MPH, and before every interval, the console prompts with a beep to inform about the incurred speed changes.

Combine exercise with entertainment, using the Bluetooth connection option that enables individuals to connect to the Sunny Health & Fitness app through their smartphone or tablet.

Hence, monitoring the fitness progress online makes it possible to make changes in the fitness routine (if needed) and achieve the desired goals.

Though a USB port is available, it can be used only for charging your electronic gadgets.

Besides these, the manufacturer has also integrated a good-quality sound system, an MP3 cable, and a tablet holder, any of which could be used to play music using the console speakers available.

Placed right on top of the console, the tablet holder comes with a strong grip surface, thereby avoiding any slips of the gadget placed over it. It is possible to fold the holder when not in use, making the unit better compact while storing it.


The treadmill comes pre-assembled. Just unbox the piece of equipment, plug it into the power supply, put on the safety magnetic key, and start working out without looking back.

But just before starting to use, ensure that the belt is well-lubricated using the silicone lubricant provided with the package.


Maintenance is part and parcel of any piece of fitness equipment, and for a treadmill, the running belt must be maintained clean.

Ensure to keep the machine free of dust, sand, or other fine particles to keep the motor in good shape.

The belt must be lubricated now and then, but the main advantage here is that the console prompts with a lubrication reminder to re-lubricate the machine after the 188-mile target every time.
