[0002] As people become more and more fond of sports, exercise bikes have become a popular fitness tool. In the field of sports science, exercise bikes are called "power bikes". They are divided into upright and recumbent (also known as horizontal) exercise bikes. They can adjust the intensity (power) of exercise to achieve fitness effects, so people call them exercise bikes.

[0003] Exercise bikes are typical aerobic fitness equipment that simulates outdoor exercise and can improve physical fitness. People can ride them for exercise, but if a running exercise bike relies on its own weight resistance to stop, it takes a long time. Therefore, an auxiliary braking system is needed to quickly stop the running exercise bike. However, the braking methods of exercise bikes on the market generally use magnetic power brakes or curved brake pad damping brakes. These braking methods require a large brake structure, occupying a lot of space, and have poor braking performance, which prolongs the braking time.

[0030] Specific implementation methods of the present utility model: After the brake structure of the fitness bike is assembled, the brake cable can be tightened or released by rotating the brake handle.
