Description of the Invention () The present invention relates to bicycles, and in particular, to bicycle shifting devices. As far as general usage is concerned, most of the transmission methods of bicycles are driven by gears and chains, and such a structure has been a problem that many cyclists have encountered for a long time, such as When the gear and the chain are matched, the chain may come out of the gear, and if this transmission structure is designed to have the function of changing speed, both the front transmission gear set part and the rear wheel linkage part must have multiple sizes. Different gears are stacked together and must be a 10-speed adjustment when the gears and chains are rotating. Such a speed-changing structure is large, heavy and complicated, and it is easy to soil the user's pants. There are often situations in which the gear cannot be pulled out of the gear chain, which is an extremely unnecessary confusion for ordinary users. The reason is that an object of the present invention is to provide a bicycle shifting device that can drive a bicycle without using a chain linkage 15. Another object of the present invention is to provide a bicycle shifting device capable of shifting even when the bicycle is stationary. In order to achieve the above-mentioned object, the bicycle transmission device of the present invention is installed on a general bicycle and connected to the bicycle speed control device. The present invention includes a circular turntable with a shaft hole at the center of the circle and is provided on the bicycle. The rotating shaft can rotate synchronously with the rotating shaft of the bicycle. The circular turntable is provided with a plurality of annular teeth in a concentric circle manner; a bracket group is pivotally arranged at the shaft hole of the circular turntable; a transmission shaft is pivotally provided On the bracket group, one end of the transmission shaft is concavely provided with a receiving groove; a driven wheel group contains the number of teeth equal to the ring-shaped teeth ---------- I (Please read the precautions on the back first (Fill in this page again)
