The invention relates to an exercise bike, in particular an intelligent resistance system for the exercise bike.

The resistance system of the traditional flywheel exercise bike is roughly divided into two types: permanent magnet resistance system and electromagnetic resistance system. The resistance of the permanent magnet resistance system (hard magnetic) can only be changed manually, and the response time is delayed, so it cannot react immediately. Therefore, it cannot match the synchronization effect of terrain and features (such as up and down slopes or emergency braking) in virtual reality.

In addition, although the electromagnetic resistance system (soft magnetic) can provide real-time response to changes in resistance, due to the lack of intelligent resistance adjustment device connection control, it cannot respond to emergency braking, nor can it provide various resistance offsets with different degrees of difficulty (offset) Level changes cannot be applied to various virtual reality software.

In summary, the deficiencies of the smart resistance system of the traditional flywheel exercise bike are:

1. In the traditional permanent magnet resistance system, the resistance is controlled and changed, and it can only be manually driven to change the resistance, and the response time of the resistance change is delayed, which cannot achieve the effect of computer control of the immediate response.

2. The traditional permanent magnet resistance system, because its resistance changes are manual, cannot match the real-time response of various changes in virtual reality.

3. The traditional permanent magnet resistance system, because of its delayed response time to resistance changes, can not match the slope changes of the virtual reality.

4. Although the traditional electromagnetic resistance system can instantly respond to changes in resistance, it lacks an interconnection with intelligent resistance adjustment, and cannot respond to the real-time situation of the human-vehicle interface urgently.

5. Although the traditional electromagnetic resistance system can instantly respond to changes in the resistance, it lacks an interconnection with the intelligent resistance adjustment, and cannot reflect the fun of the interactive process of the human-vehicle interface.

6. The traditional electromagnetic resistance system, because there is no intelligent resistance adjustment device, is too controversial in the fairness of group training or competition.

7. The traditional electromagnetic or permanent magnet resistance system has no intelligent resistance adjustment device and cannot cooperate with the different difficulty levels of the virtual reality.

8. The traditional electromagnetic or permanent magnet resistance system lacks the human-machine interface integration of the intelligent resistance adjustment device, so users cannot perform power training (FTP).

9. The traditional electromagnetic or permanent magnet resistance system lacks the human-machine interface connection of the intelligent resistance adjustment device and cannot provide the user with the purpose of cardiopulmonary training.
