Deck and running surface

The deck of this treadmill is a little bit slimmer. But nonetheless, it has a sturdy build, being able to support users up to 220 lbs (100 kg), in walking and jogging, and running sessions. Although it doesn’t have the consistent cushioning system of the LifeSpan TR 1200i or Schwinn 830, it does have a basic cushioning system, which will absorb at least 10% of the impact on your knees and ankles. This being said, running on this treadmill is definitely better for your health than running on asphalt or concrete.

The running surface supplied by this treadmill is not the longest available. But at 48.82″L x 15.75″ W, it should accommodate users up to 6’3″ (190 cm) tall without any problem. Of course, taller users should also be able to use this treadmill but they might find the running surface a little small for their maximum stride.

The tread belt supplied with this treadmill is a heavy-duty, double-layered one, designed to resist stretching. It also has an anti-slip finish, made to ensure maximum adherence when walking or running.

Although this Sunny Health & Fitness treadmill does not supply an automatic incline system, that can be adjusted from the console during your workout, it does have a manual one. This adds quite a bit to the diversity of workout possibilities that you can obtain. The treadmill’s incline system consists of two folding feet, attached at the rear part of the deck. Each foot features 3 adjustment holes, providing 3 levels of incline. The maximum incline level is roughly 7%. To adjust the incline of the deck, you must remove the pins in each foot, change the angle to the desired setting, then reinsert the pin into the apposite hole, in order to maintain that particular incline level.


The Sunny SF-T4400 treadmill is a motorized type. The motor isn’t exactly the most powerful one, but it does offer 2.20 HP. It’s a motor made to resist prolonged workouts without overheating. It supplies speeds between 0.5 MPH and 10 MPH, which is just about enough for a consistent workout. Since it’s a 2.20 HP motor, its power consumption shouldn’t exceed 1.5 KWHrs. Therefore, in case you’ve been wondering, even if you’re going to use it daily for at least one hour, the addition to your energy bill will still be negligible.

The machine comes with a power cord not an adapter. It requires to be plugged into a standard 110v power circuit. Also, the motor does have an ON / OFF power switch.


This treadmill features a steel frame, powder-coated with anti-corrosive paint. There are however several hard plastic parts on it, such as the joints of the main arms of the machine, the casing of the motor, the treadmill’s dashboard, and the incline feet.

The frame is foldable, with a soft-drop hydraulic folding system. The deck can be lifted up, to the point where it almost touches the dashboard, in order to occupy less space, length-wise.

Compared to other treadmills in this price range, this particular model features a slightly smaller footprint. It takes about 27″ W x 62″ L, which makes it an ideal choice for apartment use, or for someone who doesn’t have too much space available. It’s also a bit lighter, for example about 15 lbs lighter than the Weslo Cadence 5.9 treadmill.

The bases of the frame are finished with leveling, rubber feet, to supply maximum stability. Also, the rear base of the frame (not of the deck), is equipped with transport wheels, to ease the moving of the folded machine.

Dashboad and console

The dashboard of this Sunny treadmill model is plastic-made, featuring two bottle or accessory holders, one on each side. It’s finished with two simple handlebars, covered with rubber foam padding for a comfortable grip. The handlebars incorporate heart rate sensors, and controls for sunny SF-t4400 consolespeed, start and stop. The dashboard also offers the possibility to fit a phone or tablet onto it, as it comes with a media tray.

When it comes to the console of this treadmill, it’s not exactly the most advanced one, but it does offer quite several functions more than a basic one. For starters, it can indicate speed, time, calories burned, distance, and heart rate. The console features speed adjustment digits (+,-), each speed level adding 0.5 MPH to the current speed, up to 10 MPH. On top of that, it offers 9 preloaded workout programs, which automatically change the speed of the belt, alternating between different speed levels. There are direct digits for some of the programs on the console. It also features a Pause button, great to have in case you want or need to take a short break, without completely stopping the treadmill. Last but not least, the console has a safety key, a feature pretty much required by any treadmill.

Assembly and Maintenance

This treadmill is one of the easiest to assemble machines. Most of it comes already assembled. In other words, the motor is already in its case, connected to the deck, and the deck along with the folding mechanism are connected to the main frame. All you have to add and tighten in place are the two posts, the dashboard on top of them, and of course, connect the wires of the console.

As for maintenance, the belt requires lubrication from time to time, with a silicone-based lubricant. Other than that, just make sure to keep the deck and belt clean of any dirt or debris, adjust it if it’s the case, and make sure you don’t spill water on the console.
