The present bicycle power transmission device includes a first rotor, a second rotor, a friction member, and an elastic member. The second rotor is disposed to be rotatable relative to the first rotor. The friction member is disposed between the first rotor and the second rotor. The friction member is disposed to be rotatable relative to the first rotor. The friction member is configured to be rotated unitarily with the second rotor. The elastic member elastically couples the first rotor and the second rotor therethrough to each other. The friction member includes a base portion, a pawl portion, and a protruding portion. The base portion has an annular shape. The pawl portion extends from the base portion to a first side in an axial direction. The protruding portion is disposed radially inside the pawl portion. The protruding portion protrudes from the base portion to the first side in the axial direction. The second rotor includes an engaging hole and an engaging recess. The engaging hole causes the pawl portion to be engaged therewith. The engaging recess causes the protruding portion to be engaged therewith.
