The invention discloses an accidental starting control circuit of an electric bicycle, and belongs to the technical field of electric bicycles. The accidental starting control circuit comprises a pressure strain circuit, a primary amplifying circuit, a secondary amplifying circuit, an electric bicycle battery pack, a power supply module, a voltage comparison circuit, a handle switch and a siliconcontrolled rectifier switching circuit. A pressure strain gauge is adopted to replace a switch, and the influence caused by poor contact or adhesion due to the switch is eliminated. The pressure strain gauge is adopted as a resistance strain gauge, the size is small, installation is convenient, the gain of an amplifier IC2 can be adjusted, a good sensitivity compensation effect is achieved, and the maintenance cost is reduced.
