The Sunny Health & Fitness exercise equipment brand is one of the best in town, and the SF-T4400 model from this manufacturer is a popular one as it is released as one of the most affordable treadmills in the market.

Though the treadmill doesn’t come with a ravishing finish and hi-tech features, the machine is equipped with all the necessary features that help us stay fit and healthy.

So, if you are on the lookout for an affordable treadmill with decent features, you shouldn’t miss out on the SF-T4400 model. The motor has a decent 2.2 HP power, 10 different speed levels, a one-year manufacturing warranty on the frame, and 90 days on the parts.

Frame and Construction

The treadmill is built with a durable steel frame and guarantees against corrosion as it is coated with anti-rust paint.

Some of the parts are finished using hard plastic, and these include the motor casing, dashboard, the machine’s arms, and the inclination feet.

Don’t worry about space, as the treadmill is designed using a soft-drop hydraulic folding system—such provisioning helps us lift the deck such that it touches the dashboard, thereby making the unit compact in its vertical position.

On unfolding, the SF-T4400 model occupies a footprint that’s 27 inches in width and 62 inches in length, thereby making it fit for use for small apartments.

The frame has rubber feet at its base which ensures utmost stability while the frame’s rear side is fitted with transport wheels that help in the easy movement of the machine.

Running Area

Though slightly slimmer, the treadmill is sturdy, enabling individuals as heavy as 220 lbs to walk, run, or jog using the treadmill.

We can’t expect a great cushioning effect, but the SF-T4400 heavy-duty treadmill comes with basic cushioning that reduced the impact on the knees and joints, at least by 10%.

So, it is always better to use this treadmill for your walking/running needs rather than doing the same on the ground.

Being a compact model, the running surface isn’t long, but its measure of 48.82″L x 15.75″ W makes the machine comfortable for use by individuals up to 6 feet 3 inches in height.

The only concern is that tall individuals might find the deck’s surface area to be quite small for their stride length.

For better protection against stretching, the treadmill belt is made of heavy-duty material with a strong grip finish to protect the individual from skids and offer utmost safety while using the machine.


The treadmill comes with a manual incline system that could be changed as per our needs from the console even when working out.

There are dual folding feet present in the deck’s rear where each foot comes with 3 adjustment holes thereby making it possible for 3 levels of inclination.

You can go up to 12% inclination by removing the pins in either foot, setting the inclination, and fitting the pins back in position to exercise at your desired inclination level.

Step-up Height

The maximum inclination height possible on the SF-T4400 is only 4.37% and, hence, setting up the treadmill in a room where the ceiling height is at least 7 feet higher than the height of the tallest individual making use of the machine is essential. Only then, we can be assured of a safe workout routine.

Motor and speed

A motorized treadmill, the SF-T4400 comes fitted with a 2.20 HP motor power that couldn’t be called the best in the town.

Still, the manufacturer has done a great job designing the machine with optimal motor power that helps us achieve long workout hours without having to worry about overheating.

Also, the average motor power doesn’t consume much electricity, which is an additional advantage. So, make use of the treadmill daily for an hour, still, the energy bills remain affordable.

Along with the machine, the package includes a power cord instead of an adapter. This cord must be connected to a 110V power circuit, and the motor’s ON/OFF switch can be used when necessary.

There is no challenge without changes in speed and incline levels. Change your speed levels anywhere between 0.5MPH and 10 MPH making the workout sessions more challenging and interesting.


Never expect an affordable piece of machine to come with a classy and glossy console. Nevertheless, the manufacturer has done a decent job in fitting a console that provides us details about all basic metric values.

Made of plastic, the dashboard has provisioned for holding two water bottle holders and accessory holders on either side.

Two handlebars come with a sturdy rubber grip finish for increased safety.

On the handlebars, the heart rate sensors are present for measuring pulse, and there are also control buttons for speed, start, and stop. So, this helps you make changes to speed settings easily and also challenge yourself to push through your progress until the desired fitness goals are achieved.

Besides the primary features, the console is suitable for mixing entertainment with exercise as there is a media tray onto which the smartphone or tablet could be placed. Stream videos or listen to music using this provisioning, which makes the workout routine more interesting such that you look forward to using the treadmill.

The console, not too techy, comes with multiple functions such as an indication of speed, time, calories burned, heart rate, and distance.

There are speed adjustment options that are possible using the +/- buttons using which 0.5MPH speed changes could be made up to a maximum speed of 10MPH.

The manufacturer has designed the treadmill with 9 built-in workout options, and these programs choose the best speed levels as per requirements.

Fitted on the console is a pause button that helps you stop in between the workout when needed. Besides this, the console also comes with a safety key that helps us greatly to stop the treadmill in case of an emergency.


Assembly is always a painful procedure for most of us as the process takes time and much effort. But there should be no problem assembling the SF-T4400 treadmill as it is one of the easiest pieces of equipment to assemble.

The package comes mostly preassembled as the motor is intact in the case and connected to the deck, and the deck that hosts the folding mechanism stays connected to the mainframe.

Assemble the treadmill by fitting the two posts in their respective places, attaching the dashboard at the top, and connecting the wires of the console.


Any treadmill stays up and running only when it is maintained properly. The SF-T4400 treadmill model doesn’t differ in this regard as the belt here too needs frequent lubrication.

Use a silicone-based lubricant to keep the machine well-oiled and smooth to function.

Clean the deck and the belt freeing them from dirt and other particles. Also, ensure that you don’t spill any water on the console to keep the machine in working condition.
