The flywheel 153 is fitted with an axle 154 via a bearing, and the axle 154 is mounted in the middle of the side mounting plate 121. The transmission wheel 151 is internally mounted on the side side of the front bracket 120. A drive shaft 152 is fixedly provided, and both ends of the drive shaft 152 are installed inside the rear side of the front bracket 120 through bearings. A magnetic control assembly 160 is installed inside and outside the flywheel disk 153. The magnetic control assembly 160 includes an outer electromagnet 161 and an inner electromagnet 162. An outer magnet ring 163 and an inner magnet ring 164 corresponding to the outer electromagnet 161 and the inner electromagnet 162 are fixedly provided on the outer wall and the inner wall of the flywheel disk 153, respectively. The outer magnet ring 163 and the inner magnet ring 164 are electrically connected to the control module 142.

The other end of the belt 156 is sleeved on the outer wall of the transmission wheel 151. The inner diameter of the transmission wheel 151 is larger than the inner diameter of the driven wheel 155. Corresponding teeth are fixed between the outer wall of the driven wheel 155, the outer wall of the transmission wheel 151 and the inner wall of the belt 156, so as to facilitate auxiliary transfer transmission and make it more convenient to use.
[0029] As described in more detail in this embodiment, an idler pulley 157 is pressed against the middle of the outer wall of the belt 156, and a lever plate 1580 is hinged to the side of the idler pulley 157.

Below the wall, the lower end of the side stud 167 is connected to a reducer 144 via a coupling 145, and a servo motor 143 is installed at the input end of the reducer 144. The servo motor 143 is electrically connected to the control module 142. The servo motor 143 and the reducer 144 are supported by a lower support plate 146 at the bottom. The lower support plate 146 is fixed to the bottom of the side mounting plate 121, which facilitates the support and vertical adjustment of the external electromagnet 161 and the internal electromagnet 162. This makes it easier to adjust the distance between the external electromagnet 161 and the internal electromagnet 162 and the corresponding external magnet ring 163 and the internal magnet ring 164, making subsequent resistance adjustment more convenient.
[0031] As described in more detail in this embodiment, side sliding columns 169 are inserted through both sides of the outer end of the outer support 165 and the inner support 166. The upper and lower ends of the side sliding columns 169 are supported on the inner sides of the upper and lower ends of the side mounting frame 168.

Their principle and specific connection structure are well known to those skilled in the art, so they will not be described in detail here.
[0033] As described in more detail in this embodiment, the upper part of the rear support 110 is supported by a seat 111, and the backrest 112 is supported on the rear side of the seat 111. Side support rods 113 are supported on both sides of the front of the backrest 112. The front support 120 is covered by an outer cover 180, which is assembled by screws. A foot pedal assembly 170 is provided on the side of the drive shaft 152. The foot pedal assembly 170 includes a crank 171, and two sets of cranks 171 are fixed to both ends of the drive shaft 152. The outer ends of the cranks 171 are hinged to foot pedals 172, and the foot pedals 172 are fitted with limit straps 173. The bottom center of the base frame 100 is supported by a center support leg 101, and the front sides of the base frame 100 are hinged to movable wheels 102, which facilitates the installation and maintenance of the front support 120, and also facilitates sitting down and operation.
[0034] Working principle: During assembly and use, sit on the seat plate 111, connect the power, and then control the data processing module 141 and control module 142 via the controller 140, as well as the servo motor 143 and reducer 144 to output stable power, thereby driving the side stud 167 to rotate. With the threads at the upper and lower ends reversed, the inner support 166 and outer support 165 are synchronously moved up and down, realizing the adjustment of the distance between the outer electromagnet 161 and inner electromagnet 162 and the outer magnet ring 163 and inner magnet ring 164. The magnetic field generated after energization, along with the distance between the outer magnet ring 163 and the inner magnet ring 164, creates corresponding resistance, thereby adjusting the transmission resistance required during exercise to achieve the corresponding training effect. During exercise, the transmission of the belt 156, in cooperation with the idler wheel 157 and the lever plate 1580, and through the tension of the tension spring 1582, helps to maintain the tension of the idler wheel 157 against the middle of the belt 156, making the transmission of the belt 156 more stable. This makes the operation more convenient and efficient, and is conducive to providing the corresponding training and usage effects as needed. The operation ends here.
