Title: ELECTRIC POWER ASSISTED BICYCLE
Abstract:
Provided is an electric power assisted bicycle for executing optimal battery management when the remaining battery charge is low. An electric power assisted bicycle (1) having: a pedal crank (10) for inputting pedaling force from a rider; an assisting motor (52) for applying auxiliary force to a rear wheel (WR) or a front wheel (WF), which are cuased to rotate by the petal force; steering auxiliary devices (40, 50) for applying auxiliary force to a steering system (7); and a battery (B) for supplying electrical power to the assisting motor (52) and the steering auxiliary devices (40, 50); wherein the electric power assisted bicycle (1) is equipped with a battery management control unit (55) for controlling the electrical power supplied to the assisting motor (52) and the steering auxiliary devices (40, 50). When the battery (B) has little charge left, the battery management control unit (55) performs a control so as to prioritize the supplying of electrical power to either the assisting motor (52) or the steering auxiliary devices (40, 50) and further lower the electrical power supplied to the other of the assisting motor (52) and the steering auxiliary devices (40, 50).
