It is intended to provide a bicycle power transmission device enabling stable transmission of torque. The present power transmission device (100) includes an output rotor (2), a pair of first and second input rotors (3a, 3b), an elastic member (4), a sprocket part (6), and a crank arm (7). The output rotor (2) includes a first accommodation portion (21) penetrating therethrough in an axial direction. The pair of first and second input rotors (3a, 3b) includes a pair of second accommodation portions (31a, 31b). The pair of first and second input rotors (3a, 3b) is disposed to interpose the output rotor (2) therebetween in the axial direction. The elastic member (4) is disposed in the first accommodation portion (21) and the pair of second accommodation portions (31a, 31b). The elastic member (4) elastically couples the output rotor (2) and the pair of first and second input rotors (3a, 3b). The sprocket part (6) is provided on the output rotor (2). The crank arm (7) is attached to the first input rotor (3a).
