The invention discloses an anti-theft system of an electric bicycle. The electric bicycle comprises a pedal plate which is used for a user to pedal, wheels used for realizing a walking function, a middle shaft used for mounting the pedal plate and the wheels, a shaft sleeve used for rotationally mounting the middle shaft to a frame, a sliding locking block in rotation stopping connection with the middle shaft and capable of sliding relative to the middle shaft, and a mounting shell capable of locking rotation of the sliding locking block when the sliding locking block slides to a preset position. The anti-theft system comprises a magnetic coil used for generating a magnetic field for changing the sliding position of the sliding lock block, and a power supply device which is used for supplying power to the magnetic coil to generate a magnetic field. The magnetic coil is electrically connected with the power supply device, so that the magnetic coil generates a magnetic field which attracts the sliding lock block to be separated from the preset position. The anti-theft system of the electric bicycle has the beneficial effect that the anti-theft system of the electric bicycle has the rotating speed detection function and the electric control self-locking function.
