Frame and Construction

A strong and sturdy steel frame envelopes the entire treadmill that’s painted in a corrosion-resistant grey finish. Some of the parts, such as the motor casing, the machine’s main arm joints, dashboard, and incline feet, have a high-quality plastic finish.

The hydraulic folding system introduced in the treadmill makes it a space-saving model (succumbing to 1/3 of the original length) that’s apt for small-space apartments and homes. It is possible to elevate the deck as high as the dashboard to minimize space occupation in the vertical position.

Even in the unfolded position, the treadmill occupies only 62″L x 27″W of space. It is always better to have a clearance of 3 feet on the rear and 1 foot on either side to work out comfortably.

The treadmill is not a light-weighted one but weighs 103 lbs (46.7 kg), making it heavy to carry. But the hydraulic leg mechanism makes it easy to fold/unfold the machine easily.

The treadmill comes with rubber feet at the base for utmost stability, and the manufacturer has provided a set of transport wheels for easily moving the machine.

Running Area

The running deck of any treadmill decides upon the type of individuals who can use it. The SF-T7603 treadmill’s deck area measuring 49 inches in length and 16 inches in width makes it highly suitable for people up to 6 feet 2 inches in height to use the treadmill comfortably.

The running deck is solidly constructed using a 1-ply belt that’s resistant to stretch and made of heavy-duty material that can withstand individuals weighing as much as 220 lbs.

There are 2 shock absorbers on either side of the cushioned deck that reduce up to 10% of shocks that could impact the knees/joints.


The Sunny SF-T7603 comes with manual inclination where there are two feet at the rear of the deck. Each foot can be set in 3 adjustment positions using a solid steel pin.

In the folded position, the running surface could be inclined to as much as 8%, and when 100% unfolded, the deck rests at 0% inclination.

Step-up Height

The treadmill has a step-up height of around 8 inches when the deck is at 0% inclination.

So, if you want to protect your head from collision and bumps, it is recommended that you keep the treadmill in a room where the ceiling height is at least 15 inches greater than the height of the tallest individual using the piece of equipment.

Motor and Speed

The SF-T7603 treadmill is a motorized model that comes fitted with a 2.20 HP motor. Though this might not be as tough as commercial models, the treadmill is highly suitable for long jogging and running exercises.

Such motor power is also advantageous in terms of power consumption as the maximum consumption level would not cross 1.5 KWHrs. So, if you wish to make use of the treadmill for more than an hour daily, don’t fret about the electricity bill.

One key point to remember here is that the motor isn’t provided with a power switch to ON/OFF.

Keep challenging yourself by choosing different speed levels on the machine. The treadmill could go up to a maximum speed of 9 MPH with a possibility to increase the speed by 0.5MPH.

As the manufacturer has provided a power cord instead of an adapter, the treadmill must be plugged into a 110v power circuit.


For those of you who don’t know, the SF-T7603 is one of the most affordable pieces of treadmill that’s available in the market. Hence, it comes as no surprise that we cannot expect the console to be classy and fitted with high-end features.

For instance, there is no provision of a cooling fan, online connectivity, or sound system to combine entertainment with exercise.

Still, the company has taken care to fit the treadmill with two accessory holders that help store the water bottles, phones, remote control, or earphones.

Though not advanced, the console is not too basic either. The console has a blue backlight that makes it readable, and the digital display makes it even more comfortable for all individuals to go through the different metric readings.

Some of the display metrics include time, speed, distance, calories burned, pulse, and current speed.

The console also boasts of 9 built-in workout programs that change the speed of the running belt according to your choice of workout. The Prog key can be used to pick your desired workout choice.

High-quality stainless steel pulse sensors make their conspicuous presence on the handrails that come attached to the dashboard. The rails also have provisioned for quick speed control settings.

The primary advantage of the console is that easy to use and simple. Make gradual speed adjustments using the +/- buttons and use the quick adjustment keys to make 2 MPH, 4 MPH, and 6 MPH speed adjustments.

Any time in between the exercise, if there is a quick need to pause and restart, it can always be done using the Start/Stop keys which help you use the treadmill for circuit training too. Also, in case of emergencies, the magnetic safety key provided could always be used to stop the treadmill.

As the console similarly uses power as the motor, there is no need for changing batteries.


Assembly is always a pain for many as most of us are novices to setting up a home gym.

The SF-T7603 model spares us the daunting long hours and labor taken to assembly the machine as the package comes almost completely preassembled.

Both the console and the upright posts come assembled and attached to the deck, but they are not tightened. It is up to us to unbox the machine, fit the different bolts and covers on the joints to complete the assembly process after receiving the package.

Don’t worry about searching and picking the right tool for securing the parts in place, as the manufacturer has provided all the essential tools necessary for assembling the machine.

Besides this, the user manual provided shows all the directions in a detailed way that helps us complete the entire assembly process in less than 30 minutes.


Any piece of treadmill requires constant maintenance to keep the machine up and running in proper condition.

The running belt is the most important part of the treadmill that requires periodic lubrication, and the surprising part here is that even a bottle of lubricant is given with the package for our comfort.

It is always necessary to lubricate the machine prior to its first usage and thereon after every 188 miles of exercising.
