The DMASUN indoor cycling bike can be compared in terms of features to the SNODE 8729 cycle. However, it has a slightly different frame design and includes a large tablet holder. It’s a stationary bike made for home use, but does have a pretty decent construction, close to a light-commercial model.

Frame construction

The DMASUN exercise bike features a triangular frame made of steel tubing. Most of the frame is made of ovalized tubes for improved sturdiness and aesthetics, with the exception of the base bars which are cylindrical. The bike also includes several parts made of heavy-duty ABS plastic. However, these only have a protective role; they don’t reduce the bike’s sturdiness. The most notable ones are the belt cover, the brake cover, and the tablet holder.

The bike’s frame integrates a step-up element; not all spin bikes have this feature. It consists of a small bar that unites the seat tube with the main oblique tube of the frame. This small bar can be used for stretches as well, or for various spin workouts that require you to repeatedly mount and dismount.

The bike’s frame is fully coated with a durable paint finish resistant to chipping and corrosion. This also includes the handlebar and seat posts. The flywheel is chrome-plated with ABS side panels.

The fully assembled bike is fairly heavy. It weighs over 90 lbs (41 kg) which is more than twice the weight of road bikes. Due to this weight, the bike provides excellent stability; it shouldn’t rock or move during spin workouts. Also, both its base bars have rotating polygonal caps that can rotate, so you can level the bike on an irregular floor if it’s the case.

Like most other spin bikes, the DMASUN cycle is not an extremely large fitness machine. With the frame fully set up, it is approx. 43.5″ (110 cm) long, and 20″ (51 cm) wide. This being said, it should fit pretty well even into a small room or apartment. However, it still is recommended to allow at least two feet of clearance all around it for ease of access.

Seat and handlebars

The DMASUN indoor cycling bike is equipped with a four-way adjustable seat. Its upright post has several positions and offers an adjustment span of 10″ (25.4 cm), from 30″ (76.2 cm) above floor level, to 40″ (101.6 cm). Also, the seat’s horizontal slider allows a few extra inches of front-to-back adjustment. This being said, the bike can accommodate users between 5’0″ and 6’4″ (153 – 193 cm) with no problem.

The included saddle excels in ergonomics. To begin with, it integrates considerably more cushioning than the average race seats. Its top cover is made of durable, double-stitched faux leather. It also has a central groove for improved breathability.

One last aspect about the seat that we must mention here, regards its connection system to the slider. It’s a standard, collar-based attachment system which means the saddle can be slightly tilted forward and backward. Also, in case you will ever have to replace it, compatible options are widely available.

The bike has a handlebar similar to the L-NOW D600 cycle. It features a multi-grip design, with drop-down grips, race grips, and a loop-type aero bar in the middle. It’s fully covered by a layer of urethane material for an improved grip. The top grips integrate EKG sensors and the included exercise meter can monitor your pulse. Also, the bike includes a tablet holder that can be attached to the center of the handlebar assembly.

Unlike the seat, the handlebar only offers upright adjustment. It doesn’t have a horizontal slider for front-to-back adjustment. Also, it’s angle is non-adjustable. But on the other hand, its upright post offers approx. 10″ (25.4 cm) of adjustment, between 38″ and 48″ (96.5 – 122 cm) above floor level.

Drive and resistance

The DMASUN indoor cycling trainer features a standard friction resistance system with manual action. This means you don’t have to connect it to a power source. It also means that the bike cannot adjust the resistance automatically.

The resistance system consists of a felt brake pad connected to the tension knob. As you turn the knob clockwise, the pad applies more friction to the edge of the flywheel increasing the drag and pedaling difficulty. There aren’t any tension levels or markings on the resistance knob. You simply tighten it until you get the desired resistance.

The bike’s tension knob also works as an emergency brake; you can press it down to immediately stop the flywheel from spinning if necessary.

The DMASUN indoor cycle is equipped with a 40 lbs (18 kg) flywheel. This weight is pretty much the standard weight for most spin bikes. The flywheel is perimeter-weighted in order to provide superior inertia. It is also bi-directional; it allows pedaling in reverse, and when pedaling in reverse, you will benefit from the same resistance as when pedaling forward.

Since it’s a bike made for spin workouts, it features a heavy-duty crankset. The crank arms have a similar length and structure as the average road bike. The pedals are metallic and have adjustable toe cages for extra thrust during pedaling and superior foot stability. They don’t have clips for spin shoes but they can be replaced as their threads are standard 9/16″.

Last but not least, the bike is equipped with a belt drive system. This type of transmission comes with several advantages. First of all, it doesn’t require lubrication. Second of all, it promotes a smooth and quiet pedaling motion. And third of all, it generates less vibration than a chain drive.

Exercise meter

The DMASUN indoor cycling trainer is equipped with an exercise meter that offers a few extra features over a basic model, these being the odometer function and the pulse reading function. The other readings are time, distance, speed, and calories burned. It’s important to mention, though, that the unit is not telemetric. Therefore, it cannot read your pulse from an HR chest strap. In order to monitor your pulse, you have to hold on to the sensors integrated into the handlebar.

The bike’s meter unit is quite similar to the one included with the pooboo D680. It only has one button which allows you to scroll through the workout metrics and select the one you want to view. A Scan Mode is also available; you can select it just as any of the other metrics. And when the Scan Mode is selected, the unit rotates all the metrics showing each one for a few seconds.

The meter unit requires two AAA batteries. It also has a sleep mode to which will enter after a few minutes of inactivity on the bike. It starts up once more when you begin pedaling or when you press the button.

Assembly and Maintenance

The bike’s frame comes pre-assembled; the flywheel, the brake pad, the tension knob, the transmission belt, and the crankset are already attached. You only have to connect the two base bars, the pedals, the seat post, the seat, the handlebar post, the handlebar, and the fitness meter unit. This shouldn’t take more than one hour. The task is pretty straightforward and the included manual provides clear instructions. Also, a set of basic tools is included.

As we’ve mentioned above, the bike features a belt drive system so it doesn’t require any lubrication. The brake pad may require a bit of (silicone) lubricant from time to time, especially if it squeaks when in contact with the flywheel. Other than this, you only have to keep the unit clean and periodically check for loose parts.
