The invention discloses an intelligent safety indicator lamp system for a bicycle. The intelligent safety indicator lamp system comprises a magnetoresistive sensor, a resistive pressure sensor, a signal preprocessing chip and a display signal lamp, the magnetoresistive sensor comprises an angle sensor and a torque sensor. The magnetic resistance sensor is used for measuring the absolute rotation angle and the relative rotation angle of the bicycle and then converting the rotation angle into the steering amplitude and torque, and input signals are provided for work of left and right signal lamps of the bicycle. The resistance type pressure sensor is used for measuring the pressure acting on the brake handle during braking, a voltage signal related to the pressure is obtained, and a basis is provided for work of a brake signal lamp; the installation structure of the magnetoresistive sensor, the placement position of the battery, the program of the single-chip microcomputer and the structure of the signal lamp are designed, so that a complete automatic safe steering system of the bicycle is obtained, corresponding traffic signals can be sent out in time when people ride the bicycle, and potential safety hazards are reduced.
