An electric power-assist bicycle and an electric energy management method for the electric power-assist bicycle are provided. The electric power-assist bicycle includes a crank, a motor, a battery module, and a computing circuit. The crank is applied with a pedaling force to provide a plurality of pedaling powers to the electric power-assist bicycle. The battery module provides a plurality of battery powers to the motor. The computing circuit obtains a plurality of total demand powers and a plurality of total demand current values of the electric power-assist bicycle and obtains a plurality of distribution ratios between the battery powers and the pedaling powers. The computing circuit establishes a target function according to the total demand powers, the total demand current values, and the distribution ratios. The computing circuit obtains a target total input power according to a current pedaling power and the target function.
