A human-powered vehicle drive unit that reduces loss of human driving force includes an electric motor, a crankshaft, an output portion, a speed reducer, and a clutch. The electric motor is configured to assist in propulsion of a human-powered vehicle. The output portion is coupled to the crankshaft. The speed reducer reduces a rotational speed of the electric motor in multiple steps. The clutch is provided between the output portion and the speed reducer. In a case in which the crankshaft rotates in a first rotational direction, the output portion is configured to rotate in the first rotational direction. In a case in which the crankshaft rotates in a second rotational direction, the output portion is configured to rotate in the second rotational direction. The clutch is configured to transmit a rotational force of the electric motor to the output portion from the speed reducer.
