[0028] As shown in Figures 1 to 3 A power adjusting assembly of a training bicycle includes a left fixed plate 1, the left fixed plate 1 is rotatably connected with a driving wheel 2 and a flywheel 10, the driving wheel 2 drives the flywheel 10 to rotate. The driving wheel 2 is connected with the bicycle pedal, and the user directly drives the driving wheel 2 to rotate during training, thereby driving the flywheel 10 to rotate. By adjusting the resistance of the flywheel 10, the power is changed to realize the power adjustment of the training bicycle.

[0029] In order to increase the rotating speed of the flywheel 10, in the embodiment, a speed changing mechanism is arranged between the driving wheel 2 and the flywheel 10, the driving wheel 2 is connected with the speed changing mechanism, and the speed changing mechanism is connected with the flywheel 10.

[0030] The speed changing mechanism includes a small wheel 5 and a large wheel 6 which are coaxially fixedly connected, and the outer diameter of the small wheel 5 is smaller than that of the large wheel 6. The small wheel 5 is connected with the driving wheel 2, and the large wheel 6 is connected with the flywheel 10.

[0031] The outer diameter of the driving wheel 2 is larger than that of the small wheel 5, the driving wheel 2 drives the small wheel 5 to rotate, the outer diameter of the large wheel 6 is larger than that of the flywheel pulley 9, the large wheel 6 drives the flywheel pulley 9 to rotate, and the flywheel pulley 9 is coaxially connected with the input shaft of the flywheel 10.

[0032] Further, the driving wheel 2 and the small wheel 5 are connected through a first transmission belt 3, and the large wheel 6 and the flywheel pulley 9 are connected through a second transmission belt 7. The first transmission belt 3 is connected with a first tensioning device 4, and the second transmission belt 7 is connected with a second tensioning device 8.

[0033] The flywheel 10 adopts an adjustable load, which can adopt the following arrangements:

[0034] I. The flywheel 10 adopts an adjustable electronic load to adjust the damping size and then realize the power adjustment.

[0035] II. The flywheel 10 is a generator. In the embodiment, the flywheel 10 adopts the form of a generator. In order to facilitate heat dissipation, the flywheel 10 is an outer rotor motor. The outer rotor of the flywheel 10 is provided with a plurality of heat dissipation fins 11 at intervals.
