[0046] In the utility model, the main function of the first cross beam 15 is to firmly fix the frame 1 on the ground, to prevent the frame 1 from moving during simulation of uphill or downhill, thereby avoiding potential safety accidents. The design of the first cross beam 15 significantly improves the safety of the fitness bicycle during dynamic adjustment (such as simulation of uphill or downhill), ensuring that users will not be accidentally injured due to movement of the frame 1 during exercise. The stability is enhanced: users will feel a more stable experience during riding, enhancing their trust and confidence in using the equipment.

The display screen can display the current riding speed, heart rate and other key information, and help the user to understand the exercise state in real time. The user can intuitively adjust the inclination angle through the display screen, and the inconvenience and safety hazards caused by manual adjustment are avoided. The touch interface of the display screen is simple and easy to use, the user can quickly adjust the setting, and enjoys more flexible and diverse riding experience.
