Is the belt size of Jianyi treadmill the same?

It's different. The running belt of Jianyi treadmill is divided into different sizes, ranging from 1.6mm to about 4.0mm. Generally, there are various thin and thick running belts in China, and some manufacturers pay attention to super-thick and soft comfort. If the high horsepower and roller are not matched reasonably, it will inevitably cause excessive pressure on the motor and shorten the service life.
