The Frame & Construction 

RHYTHM Fun 4.0 HP Folding Treadmill

The RHYTHM Fun 4.0 HP Folding Treadmill is made of a steel frame that is coated with an anti-corrosion paint finish. Although, several parts are also made of ABS material and such parts included the side rail covers, the console casing, and of course the motor cover.  

The treadmill supports users that are not more than 265 lbs./120 kg in weight.  

As aforementioned, it doesn’t require any assembly, and once folded, it could be stored up against the wall or under a couch/bed that has more than 9’’ clearance.  

The unit is not very bulky; its overall assembled dimensions are 64’’ long by 33’’ wide by 46.5’’ high. Consequently, a workout area with measurements of 5’33’’ (162.56 cm) in length by 2’75’’ (83.82 cm) in width will be required.  

On top of that, a clearance of 2’ should be considered on each side and at least 3’ on the rear end of the treadmill for safe and easy access purposes.  

The deck’s step-up height is 7’’, low enough for every user to easily step in and out of the unit without struggling.  

There are transport wheels at the front base of the treadmill designed to help users to easily relocate it around the room even though it weighs 132 lbs./59.87 kg.  

By the way, to optimize stability, you may want to have it placed on a protective rubber mat which will also prevent floor damage, especially if it is going to be used on a wooden floor.  

The handrails feature speed control and ON/OFF buttons for easy and quick access. However, the downside is that one could easily and mistakenly push the OFF button which will consequently cause the display to wipe and reset your workout data. 

This has been the complaint of some users. Therefore, you may want to be careful when using the treadmill if you don’t want your current workout data to be lost.  

The Deck of the RHYTHM Fun 4.0 HP Folding Treadmill 

The deck and the motor of the RHYTHM Fun 4.0 HP Folding Treadmill

The deck features a suspended shock absorbing system that reduces impact to the joints as you exercise on the treadmill. There is a 7-layer separated soft running board and a running belt, and the top layer is also textured to improve traction.  

The tread belt dimensions are 50’’ length by 20’’ width, spacious enough for users that are up to 6’2’’ tall to walk, jog, and even run on it.  

The belt runs smoothly without friction because it runs over crowned rollers and quality ball bearings.  

The side rails are about 3’’ (8 cm) wide. These could come in handy whenever you wish to momentarily step off the running surface without having to turn off the treadmill since there is no pause button.  

Incline System 

There is no incline system. The running surface is not even slightly inclined by design but horizontally flat.   

The Motor 

The RHYTHM Fun 4.0 HP Folding Treadmill is equipped with a powerful 4.0 horsepower motor that provides the drive needed for your workouts. This means the motor has your workout sessions covered because you won’t experience any overheating or breakdowns no matter the duration or how fast you exercise.

Having said that, it is always advised to let the treadmill cool off for 10 minutes after every 2 straight hours of usage.

The motor doesn’t binge on electric power, and it is considerably vibration-free and quiet at less than 50Db.  

In other words, you should be able to conveniently watch a TV show or listen to music without having to amplify the volume beyond the normal level while working out. However, exercising at a high speed might generate some noise due to your cadence (footfall) and weight.  

The treadmill needs to be plugged into a 110V power outlet and the ON/OFF switch is located down at the front base.  

The motor provides a speed range of 0.6 mph to 9.3 mph (1 km/h to 15 km/h).  

As aforementioned, there are speed control buttons on the right side of the handrail that allow you to adjust the speed level incrementally by 0.1 km/h on the fly. There are also quick speed buttons on the dashboard that enable you to adjust the speed level by 2 km/h, 4 km/h, 6 km/h, 8 km/h, 10 km/h, and 12 km/h.  

The Console 

The Console is wide and large with a big dashboard that could accommodate a laptop. It features an LED display screen that keeps track of workout stats such as Time, Distance, Speed, Calories, and Heart Rate. 

The display is clear and bold, meaning it could clearly be read even in a room with poor lighting.  

The speed and distance are measured in km/h and kilometer, respectively, with no option to toggle to mph and miles.  

Grasping the EKG HR contact sensors on the handrails during a workout is the only way to have your pulse rate read and displayed on the monitor. Differently put, the console is not telemetric.  

The console is Bluetooth enabled and it’s compatible with the YPOO workout app. The workout app is free to download from the Google and Apple app stores. In other words, it is available for Android and iOS-based smartphones.  

The installation of the app includes scanning a QR code that is provided.  

The app allows you to track your workout progress online, and have access to private coaching, fun games, and more. Having said that, it doesn’t have a very good approval rating by actual users as a result of poor user experience.  

The Bluetooth connectivity also enables you to sync your smartphone with the built-in speakers on the treadmill for audio output.  

Finally, there are preset workout programs that help you to achieve your fitness goals.   


The treadmill has a dashboard that could accommodate a laptop.  

There are also Bluetooth built-in speakers for audio streaming.

There are transport wheels at the front base that were designed to help in the relocation process. Therefore, even though the treadmill weighs about 132 lbs./59.87 kg, one person can easily roll it away to & from the storage area.
