In a drive unit in an electric-motor-assisted bicycle, as viewed in an axial direction of the crank axle, a substrate housed in a housing does not overlap a reduction gear but overlaps a driven gear. The substrate is disposed around the crank axle and includes a component side extending in a direction crossing the central axis of the crank axle. The substrate extends in directions crossing radial directions of the crank axle. One end of the substrate in the direction in which the substrate extends is located on the side of the straight line connecting the shaft center of the crank axle and the shaft center of the motor output shaft as viewed in the axial direction, that is opposite to the side having the other end of the substrate in the direction in which the substrate extends.
