Abstract: The present disclosure provides a wind resistance type spinning bike, including a frame assembly. A fan assembly is installed at a front end of the frame assembly by a fan fixing assembly. A drive assembly is installed at a rear end of the frame assembly. The drive assembly is connected with the fan assembly by a multi-groove belt. The drive assembly may drive the fan assembly to rotate. Swing armrest assemblies are installed on two sides of the front end of the frame assembly, and are connected with the drive assembly by connecting rod assemblies. A seat cushion assembly is installed on an upper portion of the rear end of the frame assembly. By arranging the fan assembly, during operation by a user, the air flows to promote indoor air circulation, thereby enabling people to effectively persist in exercising and preventing heat stroke.

Abstract: A weight loading system for fitness equipments includes a fitness equipment support, a rally rope, a motor, a motor driving and a motor control unit. The motor is a permanent magnet brushless DC motor with an external rotor structure, and the motor includes a stator mounted onto the fitness equipment support and an external rotor sheathed on the stator and rotatable with respect to the stator, and the rally rope is wound around the external rotor of the motor, and an end of the rally rope is coupled to the external rotor of the motor, and the other end of the rally rope is coupled to the power driving mechanism of the fitness equipment; the power driving mechanism is provided for driving the external rotor of the motor through the rally rope to rotate and generate a rally, and the motor control unit controls the motor to rotate in an opposite direction through the motor driving module, so as to produce a load force opposite to the rally.
