The invention provides a method for verifying the reliability of a motor clutch for a power-assisted bicycle, and the method comprises the steps that: a brake is powered on, and a brake disc is locked; a motor is started and stalling is started; when a locked-rotor current of the motor is detected to reach a first preset value and the rotating speed V1 of the movement is equal to 0, the brake is powered off, the motor starts to drag an inertia wheel to rotate, when the rotating speed V2 of a hub reaches a second preset value, a controller controls the motor to be powered off and the inertia wheel starts to reversely drag the motor to rotate, and when V1/V2 is larger than (1-eta) i and is less than (1+eta) i, the hub reversely drags the movement and the clutch is clamped; when the conditionis not met, the brake is powered on to brake the inertia wheel; when V2 is equal to 0, one-time test circulation is completed, the system returns to the initial state, the acceleration.
