Due to the large weighting of the magnetron wheel of the exercise bike to obtain the required resistance, the construction needs to increase the size of the magnetron wheel, thus causing the problem of 4 M330843, which cannot be reduced in cost. In view of the above-mentioned shortcomings in manufacturing and manufacturing, the main purpose of the present invention is to increase the resistance of the magnetron wheel by means of shifting, and to reduce the weight of the magnetron wheel to obtain the effect of reducing the cost. In order to achieve the above object, the present invention provides a transmission structure of a magnetron wheel of an exercise bicycle, which comprises: a transmission structure bracket; a transmission wheel structure, the transmission wheel structure includes a pivoting structure in the transmission structure bracket - a driving wheel, a shifting wheel set and a magnetron wheel, between the driving wheel and the shifting wheel set, an input transmission belt is disposed, and an output transmission belt is sleeved between the magnetic control wheel and the shifting wheel set Wherein the shifting wheel set includes more than two shifting wheels, and a further transmission strap is disposed between the shifting wheels, and the number of turns of the driving wheel, the shifting wheels and the magnetron wheel is rotated. Zoom out from front to back. Further, the shifting wheel set of the present invention includes a first shifting wheel and a first shifting wheel. The first shifting wheel forms a small driving wheel on the side of the driving wheel to form a small driving wheel on the other side. a larger diameter driving wheel, the second shifting wheel forms a smaller diameter driving wheel i on the side of the first shifting wheel, and the magnetic wheel is formed on the other side to form a larger diameter than the driving wheel. The input drive belt sleeve is sleeved between the driving wheel and the first shifting jaw j driving wheel, and the driving belt sleeve is sleeved on the driving wheel of the first shifting wheel of the driving wheel 2 of the first shifting wheel, and the output driving belt sleeve It is arranged between the magnetron wheel and the driving wheel of the first double speed wheel. Furthermore, the transmission structure bracket of the present invention comprises two side plates on the left and right sides, and a crank shaft and a M330843 fixed-axle are respectively pivoted on the front and rear sides of the two side plates; the driving wheel system is sleeved and combined The rotating shape is sleeved on the axle, and the first is changed to the first: the control wheel is set on the axle and located behind the driving wheel, and the second variable reverse motion mode is sleeved on the crank and is located in the magnetic control The front of the wheel is set in the exercise bike when it is used for the purpose of turning, and it will be active and coiled; the shaft is combined, and the magnetic force of the rear end is driven by pedaling the crank shaft to provide the user with the motion of the crank.

"About", the transmission speed of the drive magnetron is increased due to the transmission speed of the drive magnetron. Therefore, the resistance of the rotating magnet 4 is also the same as that of the old--the same for the same motion resistance. The size of the control wheel can be given to 乂, 、, 、, and the weight can be reduced, which can effectively save the use of the material and reduce the overall manufacturing cost of the exercise bike.
