A power module (1, 1a, 1b, 1c) of an electric assisted bicycle is disclosed and includes a pedal shaft (10), a housing (20), a motor (30), a reducer (40) and a gear-plate output shaft (50) and a sensing component (60). The housing (20) includes a partition portion (24) extended along a radial direction to divide an inner space of the housing (20) into a motor accommodation portion (201) and a reducer accommodation portion (202) for accommodating the motor (30) and the reducer (40), respectively. A stator (31) of the motor (30) and a fixed gear (43) are respectively fixed to a first side (S1) and a second side (S2), which are two opposite sides of the partition portion (24). A reducer input shaft (41) includes two ends connected to the motor (30) and the reducer (40), respectively, and an input-shaft main part (411) disposed therebetween is connected to a third side (S3) of the partition portion (24). With the connection configuration of the three sides (S1, S2, S3) of the partition portion (24), the space utilization of the entire power module (1, 1a, 1b, 1c) is optimized.
