According to the sensor structure of the chain-free transmission bicycle, a five-way body is provided with a pedal middle shaft in a penetrating mode, the pedal middle shaft is connected with a spline sleeve, the spline sleeve is sleeved with a five-way gear, a strain gauge is attached to the peripheral wall of the spline sleeve, a protective shell is connected with a circuit board female clamping sleeve in an inserted mode, and an inductor female circuit board is connected between the circuit board female clamping sleeve and the protective shell in a clamped mode. A circuit board male clamping sleeve is arranged on the pedal middle shaft in a penetrating mode, the circuit board male clamping sleeve is connected with an inductor male circuit board, the inductor male circuit board is connected with a magnet tooth ring, and the inductor female circuit board is correspondingly connected with a tooth number inductor. The torsion sensor mechanism and the speed sensor mechanism are additionally arranged in the center shaft transmission structure to obtain variable signal data to control electric power assisting, proportional control over foot stepping output and electric power assisting is achieved, the purposes of saving energy and prolonging the endurance are achieved, the riding comfort is improved, and the riding safety is improved. The torsion sensor mechanism can accurately sense data signals of pedal torsion, so that more driving energy can be effectively supplemented when a user goes uphill with effort during riding, and less driving energy can be supplemented when the user goes downhill with effort.
