This treadmill may actually be the one you are in search of. Our both team members have tried their level best to push this tread to its limit and finally, when they gave us a nod with all the basic tick marks approved, we sat down to manifest its pros and cons for you.

Apart from gymming, running and doing yoga most of the time, we guys discuss our experiences on the health product or gadget we use that week. Yes, we are fitness freaks and like to share our experiences with various health products and gadgets honestly, with the world.

So, yes! You can rely on our review.

Let’s get started with our review of Sunny SF-T7515.

But before that, let’s have a bite about Sunny Health & Fitness, the company behind this tread.

Unboxing Sunny Health & Fitness SF-T7515 Smart Treadmill with Auto Incline, Speakers, Bluetooth, LCD and Pulse Monitor, Phone Function, 240 LB Max Weight

With 121 lbs of weight, Sunny SF-T7515 was not that heavy to park in one of our team member’s gym. This tread came mostly pre-assembled and with the detailed assembling instructions, assembling this tread was quite a breeze. All that was needed was to unfold the console masts and screw them in the upright position. Just some more joint covers and screws here and there. It didn’t take more than 30 min.

Although one person was able to handle the mobility and assembly of this tread, both our team members participated in the event to ensure that every step was perfectly executed. And yes, we also encourage you to grab a helping hand instead of assembling alone.

Overall Build & Quality

Sunny Health & Fitness SF-T7515 is a technically advanced treadmill when compared to Sunny SFT-4400 (Sl. no.). If you like listening to music while your run and an incline addict, this is your tread.

With a steel frame and anti-corrosive paint on it, Sunny Health & Fitness has provided a durable tread. For safety, the joints, motor and some other parts are covered with lots of hard plastic. With 121 lbs of weight, this is quite a steady tread. Besides, it doesn’t look like a bulky treadmill. Yes! we do encounter a couple of bulky ones every now and then during our review process.
On the shady side, just like the Sunny SFT-4400 (Sl. no. 2), this tread is also not suitable for overweighed fellows.

Specifications of Sunny Health & Fitness SF-T7515 Smart Treadmill with Auto Incline, Speakers, Bluetooth, LCD and Pulse Monitor, Phone Function, 240 LB Max Weight

Let’s crawl through the various specifications of this tread.


Sunny Health & Fitness folding treadmill is 64.5”(L) x 28”(W) x 50.5” (H) when unfolded. After folding its dimensions are 40.25”(L) x 28”(W) x 54.75”(H). So you need at least 64.5 x 28 = 1806 sq in. of the area when you work out with this tread. But, we recommend leaving at least two feet on both sides and at least three feet on the rear side of the tread for safe operation.

This tread comes with a soft-drop hydraulic folding system. This soft-drop hydraulic folding system eases the folding and unfolding operations. Our team members could lift the deck almost upto the dashboard with the inbuilt hydraulic system.

Quite a space-saving product.

On-Board Weight Capacity

Once Again, and we underline, this tread is not for the overweight fellas. If you are searching for a tread for weight loss and you are quite overweight (even near 200 lbs ), don’t read further, this tread is not for you. Browse for other treads’ review on our website.

For others, we tell you that our team members are having a great time with this tread.

Running Area

The running area of this tread is slightly more than Sunny SF-T4400 (sl  no.2). If you are in the taller category, your strides may not fit well on this treadmill. This tread provides 49.5” (L) x 16.5” (W) of running area. So. If you find yourself in the taller category, you may feel uncomfortable in this tread. If you don’t run with your maximum strides and of course not overweight, this tread will work like a charm for you, as it does for our team members.


This tread is not suitable for power runnings and interval trainings. Yes, that’s because this tread uses a 2.20 HP motor. We understand that it is not a powerful motor. But, this motor got tick marked from our team members for not heating up even if used for a long time. 

What does that mean?

It means that you can use this tread for walking, jogging and cardio. And you can do those workouts for a longer time without insulting the motor.

Speed & Inclination

Both our members are good athletes, so they took this tread to its speed limit one by one. Both were satisfied with the speed of the tread. The best part, this tread never shook during its peak speed. However, do note that the max speed of this tread is lesser than Sunny SF-T4400 (sl no.2).

Starting from 1 mph, this tread can go max upto 8 mph. The default is 1 mph and for your workouts, you can increment the speed by 0.1 mph. Both the console and the handrails have buttons to control the speed. These are on the right side of the console and on the right handlebar. With, Sunny SF-T7515, you need not remove your hand from the handrails just to control your jogging or running speed.

While this tread has a lesser speed limit than Sunny SF-T4400, on the brighter side the inclination is automatic. And just this automatic inclination has moved this tread quite ahead. You don’t have to step down and change your inclination manually.

This tread has 12 incline levels starting from 0% to 12% at the increment of 1%. And that’s quite more than NordicTrack T 6.5 Si (sl no. 1), which provides the inclination of only 10%. If inclines are what you are looking for, grab this tread.

Just like speed, incline controls are available on both the console and the handrails.

Our team members are fond of inclines and they gave it quite a high ranking because of it.

Features of Sunny Health & Fitness SF-T7515 Smart Treadmill with Auto Incline, Speakers, Bluetooth, LCD and Pulse Monitor, Phone Function, 240 LB Max Weight

At this rate, this tread is quite an advanced tread. Let’s gulp down its features.


With quite a large LCD display monitor, you can keep a check on your stats like speed, time, distance, calories burnt and pulse.


This tread comes with basic cushioning. Don’t expect a very good cushioning with this tread. During the cardio, our team members did feel that some impacts were absorbed. But they didn’t seem to be too happy with that.

Heart rate Monitor

Our whole team has practised a habit to monitor our heart rate regularly during our workouts. The sensors are placed well on the handrails. All you have to do is grab the rails and your heart rate is displayed in the monitor instantly.


Love to enjoy music while workouts? This tread has speakers. And who knows, may be just for you. Use the aux and accelerate your workouts with the inbuilt speakers.


Don’t like the aux port? This tread offers bluetooth support as well. You can pair up your mobile tablet or any bluetooth device for your music.

Phone Calling Support

Our team members found this feature quite exciting. With the inbuilt microphone, speakers and bluetooth, you can answer your calls without interrupting the workout.


Having health drinks instead of just water during workouts is also a good habit. There are two holders on either side of the LCD to park your bottles safely.

Also, there is a mobile/tablet holder in front of the LCD. You can place your tablet to get in sync with your favourite workout or a movie. Just for your note, this device holder may partially hide the LCD monitor, depending on device’s size.

Training Programs

In contrast to 9 training programs in Sunny SF-T4400 (sl no 2), this tread serves 12 programs on the table. These programs automatically adjust the speed and some of them can automatically control the incline as well. There are three user profiles, which means three users can have different sets of training programs on this tread. Our team members modified programs as per their needs separately on different profiles for their workouts and it worked beyond their expectations.
