The invention discloses an anti-theft system of an electric bicycle, and belongs to the field of anti-theft equipment of transportation tools. The anti-theft system comprises a controller, an intelligent control switch, an electric lock and an alarm device, wherein the controller, the intelligent control switch, the electric lock and the alarm device are arranged on a bicycle body. The controller comprises a master control unit and further comprises a signal detection circuit, a signal receiving circuit, an electric lock control circuit and an alarm circuit which are connected with the master control unit. The alarm device is connected with the alarm circuit. The electric lock is connected with the electric lock control circuit. The intelligent control switch is in wireless communication with the signal detection circuit and the signal receiving circuit. The intelligent control switch can send out high-frequency control signals and can continuously send out low-frequency signals. The signal detection circuit is used for detecting the low-frequency signals. The signal receiving circuit is used for receiving the high-frequency control signals. After the distance between the electric bicycle and the intelligent control switch exceeds the range of the low-frequency signals, once a power source of the electric bicycle is turned on and the electric bicycle signal detection circuit cannot detect the low-frequency signals, corresponding anti-theft measures can be taken, and the electric bicycle is prevented from being stolen.
