Frame and Construction

The SF-T7909 is built with a high-quality steel frame, and grey rust-resistant paint finishes, providing the user with good support and stability when training. Because its tubes are made of thick steel, they make the machine reach a weight of 114.6 pounds, which is why it is built with wheels for easy transport and location.

This treadmill helps you save space because its frame is completely foldable, standing upright for storage. Once folded, the space it occupies is only 26″ L x 30″ W x 54″ H, and when the machine is in use, it reaches dimensions of 61″ long and 30″ wide. Thanks to its hydraulic cylinder system, you can fold it safely.

Also, for your security, you have at your disposal handlebars since it has two vertical red color (you can remove them when you want) and two next to the board (where the heart sensor is).

Running Area

Regarding the weight it supports, the SF-T7909 admits users up to 220 pounds thanks to the high resistance of its belt. Its running area has a dimension of 48.5″ L x 16.5″ W, which makes it a treadmill suitable for users with a height of 6’0″ and even taller.

On the other hand, thanks to the 8 internal cushions installed in the front and back of the deck (4 at the front and 4 at the rear part), you can run without fear of injury since their function is to absorb the impact of the footsteps.


The SF-T7909 allows you to perform optimal cardiovascular training to stay in shape. This is because you can automatically incline it from level 0 to 12 directly from your console. Increasing the level of inclination of the platform is done 1 by 1. This way will allow you to find the level with which you feel most comfortable until you can reach the maximum level.

Also, for convenience, you can find buttons that incline the platform on your handlebar, so you don’t need to remove your hand while running. On the other hand, it should be clarified that the machine includes two motors, one for the operation of the belt and a smaller one that is responsible for raising the platform.

If you want to gradually improve your condition, you must take this characteristic into consideration. Choosing between different degrees of inclination is ideal; this way, you intensify the training. Being able to incline the platform from 0 to 12 degrees indicates that this is an efficient and professional model.

Step-up Height

Compared to other models, the Sunny Health & Fitness SF-T7909 has a medium step-up height since it reaches incline level 12; it rises a few centimeters above 8 ” (21 cm) from the floor to the platform.

That is why there should be an approximate 15” (38 cm) gap between your head and the ceiling.

Motor and speed

As it is an electric treadmill, it requires a motor. The higher speeds you need to reach, a motor with greater power will be required, so it has the necessary strength for the training rhythm it deserves. However, this treadmill is not suitable for high-intensity workouts because its motor only allows the user to walk or jog.

The motor is very good, but it is not as powerful as other models. However, you can jog for a long period. Its 1.5 HP motor is very well installed and protected to prevent vibrations from affecting it. If you only need a treadmill to do simple practices, just walking and jogging, don’t worry about it having very high power.

As for the speed it allows, this motor accepts a speed between 0.6 MPH and 7.5 MPH, which is not bad if you want to put aside that sedentary life. The speed can be changed gradually directly from the console to select the speed that you feel most safe or adjust it from the right handle.

You may be wondering if the Sunny SF-T7909 is noisy since it works with a motor, and the truth is that if you run at high speed, your training will be heard a bit. However, if you jog at a medium speed, the noise will not be annoying.

As for the electricity consumption, you should not worry since being a mid-range motor, it will not consume as much energy. Remember that being a machine for the home, the motor does not require very high power.


Perhaps this is the main factor for new users; this treadmill can offer you a series of pre-installed programs that are ideal for following a training routine.

The SF-T7909 has 4 displays located side by side in a horizontal position. The LED displays are divided according to their incline level, calories burned, time, steps, distance, speed, and pulse functions.

For the screen to track your pulse, you must place your hand on the sensor located on the handlebar, and this is because it does not have wireless functions for this function.

On the other hand, this console also cannot connect to the Internet and does not offer applications for advancing fitness workouts. Still, the console offers 12 preset workout programs. These programs are based on incline and speed, and the higher the program, the more difficult the workout can be.

On the other hand, as for the workouts, you can always customize them according to the speed and duration of the exercise segments so that they adapt according to your needs. You can also adapt the calories to burn, time, and distance. A nice perk that the console offers is the Body Mass Index calculator.

This function is essential so that you know what your ideal body mass should be, and for this, you only have to enter your data such as weight, height, age, etc. Thus, you can train in case you have to lose weight, so your progress will be recorded on the console.

Other functions that the console offers and that are worth highlighting are its 2 speakers and Bluetooth connectivity, so you can connect it to your mobile device or tablet and listen to music while you train. It also offers a USB charging port to never run out of battery, and you can leave your tablet on the support of the console designed for it.


One of the best things is that you will receive this treadmill already assembled. Your job will only be to adjust the handlebars by placing their corresponding bolts in place, something that you can do in just a few minutes, thanks to the tools it includes. However, in the user manual, you will have an illustrated step-by-step on how to adjust the treadmill.

On the other hand, like all-electric gymnastics machines, it will need regular maintenance to last for a long time. This maintenance consists of lubricating the belt before you use it and after reaching 188 miles.

But you should not worry about remembering when was the last time you lubricated it because the console is programmed to remind you when to do it. In addition to lubrication, try to keep the belt free of dust and check the screws or bolts from time to time to adjust them if necessary.
