An electrically power assisted bicycle (1) includes a driving system including an electric motor (33) generating an assist force assisting human power of a rider and including a control unit (32) controlling an operation of the electric motor (33); and an operation panel (60) including buttons (64A,64b,66,68,70) and a control circuit (62). The buttons (64A,64b,66,68,70) include a power button (70) usable to turn on or off a power of the driving system, and an assist force setting button (64A,64B) usable to set an assist force of the electric motor (33). The control circuit (62) accepts a press on each of the buttons (64A,64b,66,68,70) to execute a predefined process. When the control circuit (62) accepts a specific operation different from a normal operation on at least one button among the buttons (64A,64b,66,68,70) while electric power is supplied to the driving system and the control circuit (62) is operated in a normal operation mode, the control circuit (62) prohibits the power from being turned off.
