A regenerative braking method and apparatus for a power-assisted bicycle. There are a regenerative braking mode and a normal
travel mode during the forward riding of a power-assisted bicycle. In the regenerative braking mode, a
signal is sent to a motor (1) by means of a button provided on a handlebar, upon receiving the
signal, the motor (1) starts, an electrically controlled
clutch (5) is powered on, so that an output end of the motor (1) is connected to wheels, then the motor (1) stops operating, the wheels drive the motor (1) to rotate, the motor (1) generates power, and braking is performed while
energy recovery is achieved; and in the normal
travel mode, the motor (1) stops or drives the wheels to rotate, the electrically controlled
clutch (5) is not powered on, the output shaft of the motor (1) is not connected to the wheels (a coasting state) or the motor (1) drives the wheels to rotate (a power-assisted state), and the power-assisted bicycle travels normally. The apparatus and method enable a rider to select coasting and power-assisted riding or
energy recovery, so that the riding process is simple and convenient, and riding comfort is improved.
