The Frame and Construction

This bike features a heavy-duty steel frame that is coated with anti-corrosive black paint. It is mostly made of steel except for the brake pad and the belt covers, the tablet and the water bottle holders that are made of ABS plastic material.  

Its overall construction is sturdy and the base features front and rear rounded steel stabilizers with an adjustable plastic roller on each end. Thus, you can enhance the bike’s stability by adjusting the plastic rollers when you feel the need.   

Also, the bike’s stability is further boosted by its assembled weight of about 90 pounds/40.8 kg.  

However, you may want to use a protective rubber mat for optimum stability and for preventing sweat from spilling over the floor. 

You can pretty much relocate the bike to and from the storage with ease by the aid of the integrated transport wheels at the front base. 

The bike’s overall assembled dimensions are 43.5” long by 20” wide. Thus, it will need a workout area with perimeters of 3’7” length by 1’7” width by 48” high; and for safety and easy access reasons, it is recommended to add an extra clearance of at least 2’ at the rear and on each side of the bike. 

The Seat 

The seat of the DMASUN Exercise Stationary Bike

The DMASUN Exercise Stationary Bike has a large, soft, cushioned seat with a groove in the middle. Almost similar to the one on the IDEER LIFE Indoor Exercise Bike. This seat offers comfort more than the typical indoor saddle found on most cycling bikes. Its dimensions are 11.34’’ long by 8.12’’ wide by 2.56’’ thick. 

That said, you can use a gel seat cover to further enhance the seat’s comfortability if you feel the need to do so, or better still, you can swap the complete seat with another seat of your choice because its connection mechanism is standard and there are options widely available on Amazon or in your local bicycle shop.  

The seat is 4-adjustable; this means you can adjust the seat vertically (upward/downward) and horizontally (fore/aft). This makes the unit to be flexible in terms of accommodating users of different heights and sizes.  

The seat can vertically be adjusted from 30’’ to up to 40’’.  

In other words, the entire family members can use the bike in turn.  

The Handlebar

The handlebar is ergonomically designed with multi-grips. You can train on the bike in different postures due to the several grips available.  

You can work out longer due to the fact that the handlebar is coated with a soft rubber foam that prevents slippage and blisters in the palms. Differently put, it offers secure and comfortable grips.  

The handlebar is 2-way adjustable; it can be adjusted vertically (upward/downward) only. However, this boosts the bike’s overall customizability. The adjustment range is between 38’’ min. To 48’’ max.  

Both the seat and the handlebar adjustments are pretty easy and they only take a few seconds to get adjusted.  

The pulse EKG contact sensors, LCD monitor, and the tablet holder are attached to the handlebar.  

The Pedals 

The DMASUN Exercise Stationary Bike has toe-caged pedals made of aluminum alloy. They also have adjustable safety straps that keep the feet in place as the toe cages guard them. Therefore, your feet will remain secure and comfortable no matter how intense your pedaling gets.  

Although, the pedals can only allow you to use a pair of standard gym shoes. 

The Drive 

The DMASUN Exercise Stationary Bike is equipped with a belt drive system. This is the famous drive system that provides smooth and quiet operation. Users preferred this over a chain drive system because it allows them to train without having the apprehension that they might be disturbing the family or the neighbors.  

They can watch and enjoy their favorite TV show or listen to good music at a normal volume range while working out.  

Moreover, the belt drive system requires no maintenance whatsoever. Except for the fact that you may need to replace the belt in a period of a year or more depending on how frequent you use the bike. As a consolation, the bike’s warranty covers parts replacement for 18 months.  

The belt drive system consists of elements such as the heavy-duty anti-stretch belt, the pulleys, a solid crankset, crank-arms, the pedals, and the flywheel.  

Pedaling while standing is possible as long as you are within the stipulated weight of 330 pounds/149.6 kg.  

The drive system is fixed; this means that the pedals and the flywheel are fixed, thus, they spin together simultaneously that you cannot coast as you could on a road bicycle. For this reason, you must apply the emergency brake by pushing the tension knob down in order to bring the spinning activity to a halt whenever you wish to stop pedaling.  

The Resistance 

The bike features a friction resistance system that consists of a perimeter weighted 42 pounds/19 kg flywheel and the felt brake pad that is connected to the tension knob.  

It is referred to as a friction resistance system because friction takes place when the brake pad comes in direct contact with the top chromed surface of the flywheel in order to generate resistance.  

This resistance system is tough and suitable for anyone at any fitness level. Beginners, intermediaries, and even professional users can be challenged to the extreme.  

This helps to burn fat quickly and ultimately expedites weight loss, improvement of cardiovascular health, strength, and endurance.  

The tension knob allows you to increase or decrease resistance by turning it clockwise or anticlockwise respectively.  

The resistance levels are infinite, meaning there are no predefined resistance levels. You simply turn the tension knob clockwise or otherwise until you feel the right resistance suitable for you.  

The problem with this is that you may not know when you are progressing to using a higher resistance level which will help you to determine your strength and endurance progress.  

The Console 

The bike comes with a basic and simple console that features a non-backlit LCD monitor. The monitor tracks your workout progress by displaying stats such as Time, Distance, Speed, Calories Burned, Odometer, and Pulse. 

The heart rate can only be read through the EKG sensor sensors in the handlebar when you hold onto them during a workout.  

The display readability is good as long as it’s being viewed in an environment with adequate lighting.  

The console also has a SCAN function that continuously displays workout stats one at a time every few seconds. Although, you can override to set a certain workout value of your choice to display constantly.  

The monitor is battery-powered, and as a power-saving measure, the monitor automatically turns OFF when there is no activity on the bike for a few minutes and it automatically powers ON when you resume cycling activities.  

It is also possible to manually turn it ON/OFF via the use of the only button available on the console.  


The DMASUN Exercise Stationary Bike has two basic accessories and they are the water bottle and tablet holders.  

The tablet holder is well-positioned not to block the view of the monitor when a smartphone/tablet device is placed on it. So, you can watch a movie via your smartphone/tablet device and still be able to view your workout progress at the same time.  

The water bottle holder is also within reach for a quick grab of water for the maintenance of good hydration.  


The unit has transport wheels that help in the storage relocation process.  

It can be stored in a garage, or under the staircase. If you can afford a dedicated and safe workout area where you don’t have to move it then that would be the best storage option. 

Approval Rating 

The DMASUN Exercise Stationary Bike has a pretty good approval rating on Amazon. The several reviews done by real users are positive. Also, other review sites have a favorable view of the bike as well.

      There is no DMASUN Indoor Cycling Bike assembly manual available at this time. However, you can watch this YouTube video on how to assemble a spinning bike which will give a general idea of how to get your bike assembled.

      OR, you can use this link to contact the seller on Amazon (that is if purchased from Amazon) and demand for the manual.
