[0023] In order to make the above features and advantages of the present utility model more obvious and understandable, specific embodiments are hereinafter given and described in detail in conjunction with the accompanying drawings.

[0024] As Figures 1 - 3 shown, this embodiment provides a fitness bike, which includes an armrest frame 10 and a portable resistance adjustment device. There are two sets of portable resistance adjustment devices, respectively on the left and right sides of the armrest frame 10. The portable resistance adjustment device on the left side of the armrest frame 10 is used to increase the resistance, and the portable resistance adjustment device on the right side of the armrest frame 10 is used to decrease the resistance, facilitating the adjustment of directly increasing and decreasing the resistance with the left and right hands and enhancing the experience of simulating road cycling.

[0025] The portable resistance adjustment device of this embodiment includes a grip shell group, a fixed seat 21, a mounting seat 22, a return member 24, a button PCB board 25, and a speed change handle 23, wherein:

[0026] The fixed seat 21 is fixedly installed on the armrest frame 10 of the fitness bike. The mounting seat 22 is installed on the side of the fixed seat 21. The grip shell group is fixedly sleeved outside the fixed seat 21 and the mounting seat 22. Specifically: the grip shell group includes a front grip cover 26 and a decorative rear cover 27. The decorative rear cover 27 is snap-fitted with the front grip cover 26. The front grip cover 26 is fixedly connected to the fixed seat 21. The grip shell group is arranged to incline forward and upward, so that during cycling, the hands can hold on this grip shell group, adding a hand-holding part in addition to the grip on the armrest frame 10 that inclines backward and downward itself.

[0027] The speed change handle 23 is rotationally connected to the mounting seat 22 through a rotating shaft. The rotating shaft is inclined forward and upward, enabling the speed change handle 23 to swing left and right around the rotating shaft. The button PCB board 25 is installed at the position of the mounting seat 22 corresponding to the speed change handle 23. The return member 24 is made of a spring steel sheet and is installed between the mounting seat 22 and the speed change handle 23. After the speed change handle 23 is toggled by hand, it can swing towards the button PCB board 25 against the elastic force of the spring steel sheet, and after the speed change handle 23 is released, the return elastic force of the spring steel sheet causes the speed change handle 23 to return to its original position.

[0028] To facilitate the operation of the speed change handle 23, one end of the speed change handle 23 extends out of the grip housing group. A through hole is provided at the position of the decorative rear cover 27 corresponding to the speed change handle 23, and the speed change handle 23 swings within the through hole. The speed change handle 23 has an initial position where it abuts against the return member 24 in the original state and a pressing position where it touches the button PCB board 25. The speed change handle 23 swings around the rotating shaft between the initial position and the pressing position, and the width of the through hole matches the swinging amplitude of the speed change handle 23 between the initial position and the pressing position.

[0029] In this embodiment, a wire hole for passing a wire is provided at the position of the armrest frame 10 corresponding to the grip housing group. The button PCB board 25 is electrically connected to the speed change controller through a wire. The speed change controller and the button PCB board 25 can be purchased on the market. The speed change controller controls the addition and subtraction of magnetic resistance of the magnetic resistance mechanism. The magnetic resistance mechanism includes a motor, a wire rope, and a magnetic control component. The magnetic control component is rotatably arranged on the fitness bike frame. The circumference of the flywheel of the fitness bike is within the magnetic control groove of the magnetic control component. One end of the wire rope is connected to the magnetic control component and the other end is connected to the motor. The motor is a forward and reverse motor and can drive the wire rope to retract or release. The motor is electrically connected to the speed change controller. Toggling the left speed change handle 23 increases the magnetic resistance, and toggling the right speed change handle 23 decreases the magnetic resistance, enabling direct adjustment of the resistance by the left and right hands.
