Frame Construction

The YESOUL S3 indoor cycling bike has a triangular frame construction which is made of carbon steel tubing, double-coated, to protect against corrosion. The weight capacity of this bike is 120 kg. 

Although the bike is not too heavy, it offers superior stability. One motivation behind this is its lower centre of gravity. 

Furthermore, both of its footings feature easy levellers shaped with large rubber pads. Thus, it is not necessary to place the bike on a mat, but it is recommended.

Seat and Handlebars

The YESOUL indoor bicycle trainer has a saddle notably great for superior comfort. It features a gel top cover, integrated foam padding, and a durable inner shell of nylon. In addition, its top is grooved with a median focal point for ensured respirability.

It is also essential to state that the seat features a standard, collar-based attachment system. If you wear your product out or need a replacement, plenty of companies make compatible products.

The bike’s seat is four-way adjustable. The bike is best suited to people with heights ranging from 150 centimetres up to 188 centimetres.  Taller people can use this bike, but they may not be able to extend their legs entirely.  

Furthermore, the bicycle has a maximum weight limit for riders of 265 lbs (120 kg).

The Yesoul S3 bike has a multi-grip handlebar. It offers four grip options: cruise, standard, close, and climbing. A layer of high-density foam fully coats it for help with gripping.

Drive System

The magnetic resistance system’s transmission belt is built for smooth, silent operation. The belt is made of the most delicate copper wire to ensure durability. 

In addition, the drive system prevents any guide problems, as it has a guide pulley at both ends and an adjustable torque limiter. Therefore, you will notice this feature allows for easy and smooth operation. 

The Yesoul S3 bike has a belt transmission system located in the centre and between the flywheel and the back wheel. The belt also has a closed rubber cover to protect it from abrasion and wear. 

It also features a silent pre-programmed drive system with electronic sensors so that you can adjust resistance levels manually by the force of your legs.

The bike features a variable-speed controller that can be adjusted manually with two potentiometers located on either side of the pedals. The throttle position is very convenient for users because it is near the seat. 

When it comes to a workout, you can choose from various programs that feature varying levels of resistance and time ranges. You can also customize the features of your preferred schedule.

Fitness App and connectivity

YESOUL S3 comes with an app that allows you to track your fitness with ease for practical training. In addition to being connected with the fitness app, the bike has a wireless Bluetooth 4.0 system built-in. 

It also has a Bluetooth capacity of 40-meter range to help you control the bike with your smart device. 

If you are using iOS or Android, you can download the YESOUL Sports App to experience the bike. It will give you access to more workouts, training plans, and valuable features for your fitness. 

In addition, it is very convenient because it features voice prompts in English and Chinese.

Resistance system

The YESOUL S3 indoor cycling bike integrates a manual magnetic resistance system. It means that the device doesn’t need to be connected to a power source or power cord. But, on the other hand, it cannot make resistance automatically.

The bike's resistance system is made up of a magnetic brake that attaches to the tension knob. When you turn a metal knob clockwise, the magnets on the flywheel will be closer to it and make pedalling more difficult.

In contrast, the advantage of a magnetic brake is that the brakes don’t touch the flywheel. Therefore, the motion is without interruption or sound.

The bike has a mechanical belt drive with a rubberized brake pad that is designed for easy maintenance. You just need to wipe the fine dust off the friction surfaces. 

However, keep in mind that if you use this bike for indoor cycling, the resistance system could easily be disrupted due to its construction.

Drive system

The YESOUL S3 bike features a belt drive with a magnetic braking system. It provides smooth, quiet operation.

YESOUL S3 Indoor Exercise Bike Review
The belt transmission system also prevents any guide problems, as the electric motor is fitted with two guide pulleys at both ends. Thus, it ensures efficient, silent operation.

You may not need to change the pedals when they wear out because they are included in the package. However, when the pedals wear out, you will have to change them with any non-personalized pedals. 

The bicycle comes with two pairs of pedals. To use the pedal, disconnect the crankshaft from the tension knob, slide it out of the bike, adjust the length by rotating it back and forth until it is an appropriate length, then replace it in its slot. 

The left crankshaft has a rubber knob that attaches to the tension knob, which provides extra resistance for more challenging exercises.

Assembly and Maintenance

The main body of the bike comes pre-assembled. The only thing you need to attach is the two base stabilizers, the pedals, the handlebar tube, the handlebar, and the device holder. It will not take more than 30 minutes of your time to assemble the bike. 

All the necessary tools are included in the box, and the manual has clear assembly instructions in it.

Maintenance is minimal for bikes with belt drive systems. This type of bike doesn’t require lubrication since it has no gears or chains. In addition, as the brake is magnetic, it does not need to be lubricated or replaced either. 

However, I recommend that you check for loose bolts and parts now and then.

Price and Warranty

The YESOUL S3 Indoor Cycling Bike has an average price of USD 390. Furthermore, YESOUL provides customers with FULL REFUND or REPLACEMENT for the first three months for any quality-related reason and offers lifetime professional customer service and technical support. 

The YESOUL S3 Indoor Cycling Bike is backed by a 1-year warranty, which covers parts and labour. The warranty extends to 12 months for commercial use, but there are no other guarantees.
