摘要： The size of the housing (21) of the drive unit used in an electric-motor-assisted bicycle (10) is reduced. As viewed in an axial direction of the crank axle (22), the substrate (48) housed in the housing does not overlap the reduction gear (24) but overlaps the driven gear (2333). The substrate is disposed around the crank axle. The substrate includes a component side. The component side spreads in a direction crossing the central axis (CL1) of the crank axle. The substrate extends in directions crossing radial directions of the crank axle. One end (481) of the substrate as determined along the direction in which the substrate extends is located on the side of the straight line (L1) connecting the shaft center of the crank axle and the shaft center of the motor output shaft (2522) as viewed in the axial direction, that is opposite to the side having the other end (488) of the substrate as determined along the direction in which the substrate extends. As viewed in the axial direction, the one and other ends are located between the shaft center of the crank axle and the shaft center of the motor output shaft as determined along the direction in which the straight line extends.
