DMASUN Indoor Cycling Bike Review

The very first thing you might notice in the DMASUN spin bike is its classy, sleek appearance. Besides such a classy appearance, the frame is made of strong alloy steel tubes. That also makes it heavier than most other stationary bikes.

In addition to the strong frame, the DMASUN bike has an impressive 42 Pounds flywheel that gives you utmost stability while cycling. You can rarely see a 42 Pounds flywheel among budget indoor bikes.

Additionally, the flywheel combines with the magnetic brake pad to offer you a wide range of resistance levels to pedal against. Using the adjustable resistance, you can simulate real-life biking conditions. That is, pick your choice from almost no resistance to extremely hard resistance levels.

Now, here is an important thing you should know- the DMASUN indoor bike is designed to suit taller persons. That is, if you are under 5 feet, there is hardly any chance that this bike will fit you well.

The minimum inseam height they claim for this indoor bike is around 30 inches, whereas the maximum is 40 inches. Check whether your measurements can match this range.

Another thing to keep in mind is that the DMASUN indoor bike’s performance monitor is pretty basic. It shows you some basic values, and as an addition, your live pulse rates.

Other accessories that come with the bike include a water bottle holder and a tablet/device holder.

Coming to the adjustability of the DMASUN exercise bike, you can adjust the seat both vertically and horizontally. Also, the seat is wider and comes with a thicker cushion. The handlebar, at the same time, can be adjusted only vertically. There is no option to adjust it horizontally.

However, the presence of a drop handlebar is a cool feature.

Finally, this exercise bike offers you a smooth and quiet operation, thanks to the use of magnetic resistance instead of frictional resistance, and belt drive instead of a chain drive.

The use of these technologies also makes the DMASUN indoor bike easier to maintain.

Build Quality

The DMASUN indoor cycling bike comes with the ultimate build quality for a budget indoor bike. And the same is visible looking at all key parts of this incredibly strong stationary bike. 

Here is where different parts of the DMASUN bike stand in terms of build quality:


A thicker Alloy steel frame is what gives the DMASUN spin bike great stability, and a mentionable weight carrying capacity. As a result, this spin bike can withstand a weight of up to 330 Pounds.

That means, unless you weigh more than 330 Pounds, the DMASUN bike is completely safe for you.

Flywheel and Resistance 

The incredibly heavier flywheel of the DMASUN spin bike gives you extra stability while doing indoor cycling. The chromed flywheel is designed and manufactured not only to create great inertia but also to last long. 

Additionally, the flywheel combines with the magnetic resistance pad to offer you adjustable resistance. 

Speaking of the magnetic resistance, the brake pad is made up of multiple magnets. The magnetic brake pad, in comparison to the old school frictional brake pad, is way more effective and durable. 


As you may guess, strong pedals are crucial to withstand bigger weights of up to 330 Pounds. In this stationary bike, therefore, the pedals are made to carry heavier loads. 

In addition, the pedals are placed inside pedal cages, where you can put your feet while spinning. This will save you from fast rides and other possible accidents. 


Just like the pedals, the handlebar is also designed particularly to adapt to varying riding postures. In addition to the strong base material, the handlebar also has a rubber top layer to make it smoother to place your arms. 

Another notable feature to mention here is the additional drop handlebar, which is not seen commonly among budget indoor bikes.

With a dimension of 10.6 inches length, 7.8 inches width and a decent 3.2 inches thickness, the seat of DMASUN indoor bike is more than enough to give you a comfortable ride. 

Indeed, a thicker cushion is what lets you do spinning for longer durations, and the DMASUN bike has the same. 

Additionally, they’ve given a spring at the base of the seat to transmit heavier as well as fluctuating loads.

In addition to impressive build quality, the DMASUN indoor cycling bike adopts decent technologies so as to make your spinning sessions even more memorable.

Here is how this spin bike performs in terms of the technology they’ve used while designing various key components. 

Flywheel and Magnetic Resistance

As discussed already, the flywheel and the magnetic brake pad combine together to offer you adjustable resistance.

Here is how it works- The pressure exerted by the magnetic pad on the flywheel is what gives you the resistance. You can also adjust the resistance, simply by using the knob given within your arm’s reach. 

Therefore, using the DMASUN indoor cycling bike, you can experience the feel of biking through varying conditions; like going uphill, downhill, flat terrain, and dozens of resistance levels in between. 

Performance Monitor

The DMASUN exercise bike, like other budget spin bikes, comes with a basic performance monitor. 

It has an LCD display that works using 2 AAA battery cells that comes along with the package. 

However, one disadvantage with the performance monitor of the DMASUN bike is that, only one value displays at a time, and just one button to navigate among them. Therefore, you may have to keep on switching to reach the value you want to see.

Another possible drawback is that the values will be shown only temporarily, and there is no option to save or export the data. 

The performance monitor shows:

  • Time
  • Speed
  • Distance 
  • Calorie
  • Pulse rate

The presence of the pulse sensor is indeed an advantage. And a live pulse reader is not something we could see among many budget bikes.

The DMASUN spin bike is designed ergonomically to adjust a wide range of heights, especially for taller persons. In terms of adjustability, however, this spin bike is an average performer. 

The seat is adjustable in 4 ways. That means, you can adjust it for vertical height, and for the distance from the handlebar. The handlebar, on the other hand, can be adjusted only vertically. 

However, there are lesser chances that you will feel any discomfort in adjusting the DMASUN bike according to your height, except if you are very short. 

That being said, this stationary bike is ideal for persons from 5’5” and above in height. And if you are under 5’ or 5’1”, the bike will hardly be comfortable for you. 

Belt drive

Needless to say, a belt drive is far more desirable than a conventional chain drive. The DMASUN indoor cycling bike uses an advanced belt drive to transmit the energy from the pedals. 

The presence of a belt drive will make your indoor cycling smoother and quiet. Also, you won’t have to go for frequent greasing or other maintenances that you do for a chain drive. 

Assembly and Maintenance

As mentioned above, the DMASUN bike is heavier than most other spin bikes. Therefore, it might take some effort to carry the package inside your home gym. However, if you have a partner with you, it would be an easy job.

Now, coming to the assembly part, setting up the DMASUN exercise bike is quite an easy task. The frame, flywheel, and other major parts will be already connected together when the package reaches you. 

Take the instructions manual and the toolbox that arrives with the product, and start with the assembly right away. Generally, it won’t take you more than 30 minutes to assemble the DMASUN indoor bike; or a maximum, 45 minutes. 

Speaking of maintenance, just like any other indoor bike, you need to take proper care of the DMASUN indoor cycling bike for a better life. 

But here is a matter of relief- a state of art construction has obviously made maintenance of this bike much easier for you. For example, this indoor bike uses a belt drive instead of a chain drive. Hence, you will not have to perform maintenance to the drive system.

  • As a general procedure, clean the surface of the bike, especially the frame and other metallic parts as frequently as possible. We would suggest you do it daily, but leaving it all up to you.
  • Before you start cycling, check for all major screws, fasteners, and other connectors and make sure they are well connected. Otherwise, it may lead to accidents. There are only distant chances for it to happen but still, little care won’t take much effort.

Aesthetics and Styling 

We would say the DMASUN indoor bike has got above average aesthetics. Those red stripes above the shiny black frame give this bike some style.

The brand name is written across the bike, for example, on the seat post and the flywheel. 

Furthermore, due to the rough, sturdy construction, this stationary bike may look like a rough, beasty metallic piece of workout equipment. In other words, this bike does not have a fancy appearance.

Pros & Cons 

Given below are some notable Pros and Cons of the DMASUN indoor cycling bike


  • 42 pounds flywheel
  • 330 pounds weight capacity
  • Suits very tall persons
  • Safer, durable construction
  • Highly adjustable resistance
  • Drop handlebars
  • Classy appearance
  • Smooth operation


  • May not fit shorter individuals
  • Comparatively heavier
  • The performance monitor is basic


Is DMASUN Exercise Bike Worth The Buy? 

The question should rather be – ‘can the DMASUN spin bike suit me?’ because it looks like this indoor bike is designed for taller persons. If you are very short, say below 5feet, there are lesser chances that this bike will suit you. 

Check the inseam heights and compare them with yours before making a decision. 

Otherwise, there is practically no reason to deny the fact that the DMASUN bike is definitely worth the buy. It got the strongest, most durable possible construction for a budget indoor bike, and an ergonomic design that can give you great comfort. 

Besides all those cool features that make the bike trustworthy, they even offer you free parts replacement for the first 12 months. 


That was an honest review of the DMASUN indoor cycling bike. 

As a final verdict, considering various aspects starting from the build quality and user comfort, we have a fairly good opinion about this indoor bike.

And a suggestion we have is, they can do an even better job with the performance monitor. If they can do it, then the DMASUN spin bike will be truly unstoppable. 

But overall, especially considering the price, this indoor bike can be an ideal addition to your home gym.
