Abstract: A resistance regulating device for a wheel of a training device is disclosed. The resistance regulating device comprises a rotary mechanism pivotally connected with a stationary mechanism and a motor with other components to rotate the rotary mechanism and hence a distance between magnets of the rotary mechanism and the wheel is changed. In addition, an optical detection device may be used to detect and define a minimum resistance and a maximum resistance and hence to adjust a resistance in a stepless manner An emergency brake mechanism may be further employed.
