Features of Sunny Health & Fitness SF-T7515


The SF-T7515 arrives fully assembled, but in the folded position. So, users have to unfold the console masts, secure them in the upright position using the included screws, and install the protective joint covers. Users also have to secure the console in the usage position. But this shouldn’t take more than 30 minutes. The manual provides detailed assembly instructions and all required tools are included in the package.


The frame of the SF-T7515 is made of steel and is strong enough to hold users up to 250 lbs. All bars of the unit are coated with a corrosion-resistant paint. The color of the unit is white and black, and the company’s logo is in red. There are many ABS parts in the machine’s construction, the most prominent among them being the motor’s side rail covers, deck’s cover, and the covers of the joint between the console mast and base frame.


Being mainly a walking treadmill, the SF-T7515 is equipped with a light capacity motor of only 2.2 HP. But it’s sufficient for walking and jogging workouts. It has also been found to be not getting overheated and performing well even while running at its highest speed.


The machine is significantly heavy, weighing more than 120 lbs. when fully assembled. Thus it offers a great stability although it’s not a bulky machine. The adjustable stabilizers on the base add to the stability.


Although the SF-T7515 is quite heavy, the assembled unit is easy to relocate due to the two transportation wheels placed on the rear part of the front base.

Foldable Design and Soft Drop Mechanism

The deck of this treadmill is foldable and users can lift it up and lock it in an upright position, leaving the unit’s length up to around 40”. The dimensions of the unit after folding are 40.25″L x 28″W x 54.75″H (101 x 71 x 140 cm).

The hydraulic ‘soft drop’ system installed in the machine is meant for assisting users while lowering the deck slowly and softly, so as to prevent any accidents or damage to the deck while unfolding the unit.


The SF-T7515 has a mid-range console. It has an LCD display with LED backlight that improves its readability. The display is divided into several sections and shows multiple workout stats at the same time, thus users don’t have to use a scan function to alternate them. It shows workout stats such as distance, time, speed, incline and pulse.

The console provides goal settings for time, distance and calories. Users can select a target for each of these metrics and the console will start to count down from the selected value until it reaches zero, while users exercise.

The console is Bluetooth-enabled and users can sync it with their phone and can take phone calls on the speakers of the treadmill while exercising. But the console is not iFit enabled and users cannot use the Bluetooth connectivity to stream their workout data on any online fitness app or site.

Heart Rate Monitoring

The side handlebars of the SF-T7515 have pulse rate sensors integrated into them. Heart rate monitoring is done when the users hold these sensors. These sensors can also be used while performing a preset HR-based program.

Preset Workout Programs

The machine offers 12 preset workout programs that automatically adjust the speed of the belt and some of them adjust the incline too.

In addition, users can find a great library of treadmill workouts on the Sunny Health & Fitness’s website’s Workouts section and also on their YouTube channel.

There are also 3 user profiles available. Users can thus modify a program of their choice by adjusting all its 10 segments and save it for later use.

Body Mass Index Calculator

The machine is also equipped with a Body Mass Index calculator which is used to estimate body fat based on user’s height and weight. For this, users have to provide their personal information like age, gender, height and weight. BMI can be used as a reference point to determine goals and tracking fitness in different stages of training.

Running Deck

The running deck of the SF-T7515 is 49.5″ (126 cm) L x 16.5″ (42 cm) W, and thus is quite spacious for users of height up to 6’2” (188 cm). Users taller than this may feel cramped though.

The deck doesn’t have any advanced cushioning system, but does have a number of shock absorption points which alleviate a significant part of the walking impact. Thus, walking or running on this machine is pretty much kind on the joints than that on concrete or asphalt.


The SF-T7515 comes with a motorized incline system. This means that users can adjust the incline digitally and only from the console or from the controls featured in the left handlebar.

Also, an incline is automatically adjusted if users choose a preset program that involves a particular incline.

There are 12 incline levels available from 0% to 12% (or 0° to 6.9°). Incline increments are 1%. The left corner of the console as well as the left handlebar contains gradual incline adjustment controls. There are also quick incline adjustments for 3%, 6%, 9%, and 12% levels.

The step-up height of the machine is around 10″ (25 cm). When the machine is adjusted to its maximum incline, the front part of the deck gets a few extra inches added to its height. Hence, it’s advisable to place and use the unit in a room where the height of the ceiling is at least 15” higher than the user’s own height.


The machine provides speeds up to 8.0 MPH (12 km/h). The machine is set at a default speed of 1 MPH. Up from that, users can adjust the speed in increments of 0.1 MPH. So, users can match their own speed with that of the belt very easily and have a comfortable walk.

Similar to the controls of incline, the controls for speeds are also located on the console and in the handlebar, but the right one. Also quick speed controls are available on the console for the 2 MPH, 4 MPH, 6 MPH, and 8 MPH speed settings.

Emergency Stop Clip

The SF-T7515 provides a great safety in the form of an Emergency Stop Clip with which users can bring the machine to an immediate stop.


The SF-T7515 is equipped with quite a few additional features.

Firstly it comes with a sound system that consists of two speakers which provide a pretty decent sound. It’s compatible with most smartphones and MP3 payers. Users can even use the Bluetooth connectivity to listen to the music on their phones or can use the audio jack input. The console provides pause/play, volume controls, and track selection.

Secondly, the unit includes a phone/tablet holder located between the two sets of controls on the console. It’s quite spacious and can accommodate any phone or tablet.

Plus, there are trays on each side of the console which can be used as water bottle holders or to keep various other accessories.

Noise Level

The motor of the SF-T7515 is pretty quiet. Also as most users will walk on this machine, the cadence noise too will be minimal.


The deck of the machine will need lubrication on a regular basis. The starter bottle to be applied before the first use is included in the package. It also should be cleaned regularly to prevent any fibers or other objects from getting caught into the motor. In addition, users will need to periodically watch out for any loose bolts and parts, and re-center the belt if required.
