A bicycle electricity-generating flower drum capable of measuring speed comprises an electricity-generating flower drum body, a rectifying circuit and a speed measuring circuit, wherein the rectifying circuit comprises a bridge rectifier circuit, a filter circuit and a DC/DC circuit which are connected in sequence, the speed measuring circuit comprises a waveform shaping circuit and a single chip microcomputer circuit, and the output end of the electricity-generating flower drum body is connected with the rectifying circuit and the speed measuring circuit respectively. The single chip microcomputer circuit is further connected with a wireless communication module. The electricity-generating flower drum body of the bicycle electricity-generating flower drum capable of measuring the speed is divided into two circuits, namely a power circuit and a detection circuit, and accordingly the accurate measurement purpose is achieved by converting alternating signals into detection signals. Electricity generation, speed detection and mileage statistics can be achieved through one part, results are wirelessly transmitted to a display device through the wireless communication module, and the bicycle electricity-generating flower drum has the advantages of being convenient to use and reasonable in structure.
