Sunny Health & Fitness ASUNA 7750 Treadmill Review


ASUNA SpaceFlex Treadmill









The ASUNA 7750 is one of the latest motorized treadmills released by Sunny Health & Fitness Store. If you are looking for a treadmill to walk and jog at home, this is one of the best products in the market today for its price. The ASUNA 7750 isn’t designed for people looking for a treadmill to run at high speeds. But the machine does provide a range of impressive features including a motorized incline system which you won’t find in competitor machines. The ASUNA 7750 is a compact machine designed to offer dual folding possibilities. Read our review below to see how we think it stacks up against the competition.

Walking on treadmillFrame & Deck

The 7750 isn’t a large machine. In fact, it has a compact design with an assembled footprint of 57 inches in length and 29.5 inches in width. For safe operational purposes, you should leave at least 3-feet of clearance at the rear of the unit and 2-feet of clearance on each side. You can fold the machine and store it vertically or horizontally depending on the space situation in your home. If you decide to fold the unit vertically, the dimensions are 12″ D X 59″ H X 33″ Width. The machine doesn’t have a hydraulic system. So you need to fold the console and the console masts down over the deck instead of folding the deck up like with other machines. If you want to store the unit vertically, you should pull out the second set of wheels at the front top part of the deck and lift the deck up. The wheels play the part of a stabilizer to prevent the deck from falling off once folded vertically.

The ASUNA 7750 is quite heavy once assembled. For example, it weighs around 127 lbs when assembled. The weight helps stabilize the machine which is also enhanced by rubberized and adjustable stabilizers. Since the front base of the unit is equipped with transport wheels, you can easily relocate the machine although it’s heavy. The unit has sturdy construction with a heavy-duty and durable steel frame. It also has thick console masts. All of the steel components of the 7750 are coated with a corrosion-resistant and chip-resistant paint finish.

The deck can support up to 220 lbs and is equipped with 3 shock absorption elements on each side. Jogging or walking on the deck won’t impact your joints due to this reason. In fact, you can jog or walk for longer periods without having to worry about joint-related stress and pain. The platform is not large as with a running treadmill since the 7750 is designed for walking and jogging rather than running. In fact, the running platform is 51.2″ long and 19″ wide and isn’t the best choice for any user taller than 6-feet 2 inches.

The rail side covers of the deck are made of high-quality and durable ABS plastic material. Anti-slip stickers offer extra stability and foot adherence if you decide to rest while working out without stopping the belt.


The ASUNA 7750 comes with a 2.5 HP motor that offers more than enough power to walk or jog on the machine. It can support users up to 220 pounds for long-duration exercise routines. The motor won’t lose performance or overheat during such sessions. The speed range offered by the motor is between 0.6 to 8 mph. You can adjust the speed of the machine using the controls built-in in the right hand-grip. It comes with 0.1 mph adjustment increments. You have the option of finding the perfect pace for your workout with the speed settings. The console has 2 quick keys to adjust the speed of the machine such as one key for 3 mph and one for 5 mph. The motor isn’t noisy as with competitor machines. You can barely hear the cadence while walking or jogging on the unit. Since the motor isn’t that powerful, you don’t have to worry about the electricity consumption even if you plan to use the treadmill on a daily basis.

Incline Treadmill RunningIncline

This treadmill has a motorized incline system with 12 levels of incline. Even when the incline is set to zero, the running platform isn’t completely horizontal. For example, even when the incline is set to zero, the deck still has a 2.3-degree incline. The incline system is automatic and can be adjusted from the control keys built-in in the left hand-grip. The control provides quick incline buttons for the 3rd and 5th incline levels. On the other hand, some of the preset exercise programs involve the incline system. When you decide to use a preset workout program, the machine will automatically adjust the incline level.

The step-up height of the deck is approximately 6 inches. When the incline is at its highest setting, the front part of the deck will be elevated by at least 2 inches. The incline increments of the machine are 0.4%, from 4% incline to 8.7%.


The machine has an LED console with 6 displays indicating incline, calories, time, program, speed, and distance. The console has 8 buttons including start/pause/program/mode, and incline quick controls for there and five-level settings. But the console doesn’t have any other online capabilities since it isn’t compatible with any online fitness app. The unit has 8 preset workout programs as well as 3 custom workout programs to motivate you to achieve your fitness goals. The console has a built-in sound system compatible with most MP3 players and mobile devices. There are two speakers, one on each side of the console. There is also a folding tablet holder placed at the rear/top of the console to accommodate any size of tablets.


The ASUNA 7750 doesn’t require any assembly at all. It is fully assembled and folded. You should unfold the machine and attach the side handlebars and the machine is ready to use. Make sure you lubricate the running belt every five months to prolong its lifespan.

Final Words

All in all, the ASUNA 7750 SpaceFlex Treadmill (available at Amazon) is an excellent offering for anyone searching for a treadmill that works well in small living spaces. The low-profile design coupled with quality workmanship ensure buyers will enjoy their purchase for a long time. Offering a surprising array of features provides users with a flexible and comfortable workout. The machine is quiet and capable, although a slightly stronger motor would add to the appeal. The Sunny ASUNA treadmill provides users a commercial-grade workout in the comfort of their home and without the fuss.
