[0002] With the continuous enhancement of people's health consciousness and the continuous improvement of life quality, fitness activities have been deeply integrated into people's daily life and become an indispensable part. As a kind of convenient and efficient riding exercise equipment, fitness bicycle can be flexibly deployed in various environments because of its relatively loose requirement for installation space, whether it is a warm family room, a professional fitness club or an outdoor open park green, its figure can be seen.

[0003] The traditional fitness bicycle structure is quite classic, and the core components usually cover the flywheel, the precise transmission system and the pedal. The flywheel, a key component, is usually made of high-density metal and has considerable weight, which is stably placed at the front end of the bicycle. It not only plays the role of storing and releasing energy, but also provides the necessary exercise resistance for the rider. The transmission system skillfully uses chain or durable belt as medium to connect the flywheel and the pedal under the user's feet closely, ensuring the smoothness and efficiency of power transmission.

[0004] When the user steps on the pedal and drives the pedal to move in a circle through the leg muscle power, the power is immediately transmitted to the flywheel through the transmission system, which makes it rotate slowly. In this process, the flywheel creates a training atmosphere close to the real outdoor riding experience for the user with its own weight, which can effectively exercise the heart and lung function and strengthen the lower limb strength, and is an ideal choice for people pursuing healthy life. However, in the process of using the prior art, since the weight of the flywheel is fixed, if the training intensity needs to be increased, i.e. the rotating resistance of the flywheel needs to be increased, a heavier flywheel needs to be replaced for use, which is not convenient for the user to operate.
