The Frame & Construction

The THERUN Magnetic Exercise Bike has been designed to provide users with an intense exercise experience. Its sturdy frame and durable construction guarantee its stability and longevity, even during strenuous exercise routines. This fitness equipment is ideal for those in search of a stimulating and demanding workout. 

The frame of the THERUN Magnetic Exercise Bike is constructed from robust, high-quality alloy steel This makes it an ideal choice for both home and commercial gym use (although, not meant for commercial use), as it can withstand the pressures of daily use, and providing a secure and stable base for the bike. 

Its frame structure and flywheel position look like that of the Keiser Magnetic Indoor Cycling Bike.  

The unit supports a maximum user weight capacity of 300 lbs./136 kg.  

Its assembled dimensions are 53’’ long by 31’’ wide by 45’’ high. Differently put, the unit will require a workout area with measurements of 4’4’’ (134.6 cm) in length by 2’5’’ (78.74 cm) in width.  

Furthermore, it is recommended to add an extra clearance of 2’ on either side and the rear of the bike to allow users to train in safety and comfort.  

The bike is fairly heavy as it weighs 97 lbs./44 kg. However, it can easily be moved around because of its front-mounted transport wheels.  

Lastly, the use of a protective rubber mat might be necessary to prevent floor damage and improve overall stability.  

The Seat of the THERUN MTB108 Magnetic Exercise Bike with Bluetooth 

The seat is designed with maximum comfort and adjustability in mind.  

It is made from durable materials and is contoured with a groove at the surface to provide breathability, optimal support, and comfort. Therefore users can exercise for long periods without feeling any discomfort or pain. 

The seat is 4 ways, i.e., upward/downward and fore/aft, thereby giving the user the opportunity to customize the bike for a perfect fit.

The adjusters make it easy and quick to adjust to desired positions.  

Due to the adjustability of the seat users between the heights of 5’-6’2’’ tall can be accommodated.  

That said, the use of a gel seat cover might be necessary for maximum comfort because the seat does not have much of a cushion on it.  

The Handlebar  

The THERUN Magnetic Exercise Bike stands out from other models due to its superior handlebar design. Its ergonomic construction ensures maximum comfort and convenience during workouts, allowing users to get the most out of their exercise routines. 

Its multi-grip design allows the user to train in different postures. The handles are coated with anti-slip rubber foam for firm and comfortable grips.  

The handlebar is 2-way adjustable. Thus, users can customize for a perfect fit by adjusting it vertically (upward/downward).  

There are no heart rate sensors on the handlebar, as a result, heart rate cannot be monitored during a workout.  


The THERUN Magnetic Exercise Bike pedals have been crafted to safely support diverse workout intensities and techniques. The adjustable straps and toe cages ensure your feet remain secure and stable, eliminating any sliding or discomfort while exercising.  

The straps can be tailored to fit any foot size, providing a custom fit for almost everyone. 

They are attached to a 3-piece crankset and durable crank arms that can support a maximum user weight capacity of 300 lbs./136 kg even when the user pedals while standing. 

That said, the pedals are not dual-sided, which means they only support regular gym shoes and not special spin shoes.  

The Drive of the THERUN MTB108 Magnetic Exercise Bike with Bluetooth 

The bike is equipped with a belt drive system that comprises a v-poly belt, a pulley, and the 35 lbs./15.87 kg perimeter weighted flywheel.  

Thus, the bike’s operation is smooth and quiet, therefore, users can exercise with it around family members without disturbing them.  

Users can pedal in reverse if they wish to diversify their workout and tone more muscle groups.  

The Resistance System 

The resistance and incline of the THERUN MTB108 Magnetic Exercise Bike

The THERUN Magnetic Exercise Bike features an electromagnetic resistance system, which works by adjusting the space between the magnets and the flywheel. Thus, the resistance intensity is changed between easy to difficult levels and vice versa.  

A small servo motor is involved in the process of generating resistance. It is responsible for shifting the magnetic brake pad closer or farther away from the flywheel depending on the applied adjustment by the user.  

Therefore, for the resistance system to work, the bike needs to be plugged into a power outlet.  

One of the benefits of this type of resistance system is that it does not create any noise when the resistance is engaged, thereby making the overall operation of the bike smooth and quiet.  

The magnetic resistance system provides 32 intensity levels, from gentle to demanding, so users can customize their workout to fit their individual needs. No matter where you are on your fitness journey, this bike has the right level of resistance for you. 

The resistance and the incline can be adjusted manually or automatically when connected to a workout app via Bluetooth.  


The console of the THERUN MTB108 Magnetic Exercise Bike

The MTB108 Magnetic Exercise Bike with Bluetooth from THERUN is designed to maximize your workout experience. Its user-friendly and innovative smart dial console makes it easy to track your progress and stay motivated with its intuitive design. 

The LCD monitor tracks Time, Distance, Slope (incline), Resistance, and Calories with high clarity that can’t be diminished by any lighting condition of a room.  

This real-time feedback allows you to monitor your performance and make necessary adjustments to achieve your fitness goals. 

The console is Bluetooth-enabled. Thus, users can wirelessly connect a smartphone/tablet device to the bike so that they can access a range of interactive and immersive fitness apps. Some of these apps feature workout programs, coaching sessions, and virtual cycling routes, making your workout more fun and engaging. 

Furthermore, the Zwift workout app supports the incline technology the bike has. When connected to it the bike’s incline and resistance will automatically adjust depending on the virtual terrain you are on while cycling.  

There is a tri-color taillight on either side of the flywheel that shows up whenever the incline and the resistance are adjusted. Depending on the incline and resistance level, the taillight may show a green, blue, or red color.  

By the way, the console is compatible with other workout apps such as Kinomap, FitShow, and more.  


The cycling bike has a large retractable tablet holder that can securely accommodate a smartphone or tablet device. It is placed above the console/display, hence, any device placed on it can’t block the view of the monitor.  

You will be able to monitor your workout progress while you use a workout app or watch an entertainment video simultaneously. 


The MTB108 Magnetic Exercise Bike with Bluetooth is not overly large, therefore, it won’t take up too much storage space.  

It can fit next to a wall or under the staircase.  

The integrated transport wheels at the front base allow you to easily roll it away by raising it from the rear and tilting it toward the front.
