The invention provides an operation method of an electric power-assisted bicycle. The operation method comprises the following steps that stepping force supplied by a driver is received, and torque is transmitted by a chain wheel of the bicycle to a fly wheel through a force transmission mechanism; a support mechanism bears force supplied by the force transmission mechanism in the torque transmission process and drives a connecting rod connected with the support mechanism to generate motion state changes; a detection mechanism detects the motion state change quantity of the connecting rod; an assistant motor responds the motion state change quantity of the connecting rod to output electric power for assisting the stepping force.
