It is intended to provide a bicycle power transmission device suitable for a user. The present bicycle power transmission device (100) includes a first rotor (2), a pair of second rotors (3), an elastic member (4), and a stopper member (5). The pair of second rotors (3) is disposed to interpose the first rotor (2) therebetween in an axial direction. The pair of second rotors (3) is attached to each other so as to be detachable from each other. The elastic member (4) elastically couples the first rotor (2) and the pair of second rotors (3). The stopper member (5) is disposed between the pair of second rotors (3). The first rotor (2) includes a stopper surface opposed to the stopper member (5) at an interval in a rotational direction.
