The utility model discloses an electric bicycle emergency power-off protection device which comprises a controller, the controller is electrically connected with a tilt angle sensor, the tilt angle sensor detects the tilt angle and transmits detection information to the controller, the controller is electrically connected with a circuit breaker through a triode, and the controller is electrically connected with a battery. The battery is further electrically connected with the circuit breaker through the step-down transformer and the rectifying circuit, the circuit breaker is electrically connected with the motor through the motor switch, and the motor is electrically connected with the controller. The controller sends out a voltage signal to conduct the triode, the breaker is powered on to disconnect the motor switch, and the motor stops rotating. Inclination angle signals in the running process of the vehicle are collected through the inclination angle sensor and transmitted to the controller, if the inclina
