A power-assisted bicycle (1, 71, 101) includes a front wheel (10), a rear wheel (5), a body frame (6), a bracket (14) for mounting a power unit, and a power unit (15) fixed to the bracket (14) by a fixing bolt (53). The power unit (15) includes a pedal crank shaft (16) and a motor (42) for auxiliary power, and outputs each of human power applied to the pedal crank shaft (16) and driving force of the motor (42), or the resultant force of the human power and the driving force of the motor (42), to the outside. The bicycle (1, 71, 101) also includes a chain (29) for transmitting the resultant force of the human power and the driving force of the motor (42) to the rear wheel (5). The bracket (14) includes a front mounting seat (61) and rear mounting seat (62) pointing downward. The power unit (15) includes first and second front mounting portions (51, 52) and first and second rear mounting portions (55, 56) which overlap the front mounting seat (61) and rear mounting seat (62) from below. The fixing bolt (53) extends in a direction in which the front mounting seat (61) and rear mounting seat (62) and the mounting portions (51, 52, 55, 56) overlap each other, and fastens the mounting portions (51, 52, 55, 56) to the front mounting seat (61) and rear mounting seat (62). This invention can provide a power-assisted bicycle (1, 71, 101) capable of improving both the fastening properties and rigidity when mounting the power unit, while reducing the manufacturing cost.
