A bicycle electric power generating device includes a shaft member, a rotation body coaxially rotatable relative to the shaft member, an armature provided on one of the shaft member and the rotation body and a magnet having circumferentially arranged poles provided on the other one to rotate relative to the armature. The armature includes a first yoke with at least one first yoke pieces, a second yoke with at least one second yoke pieces, and a coil. The first and second yoke pieces are arranged parallel to an axis of the shaft member so as not to overlap with each other in a circumferential direction of the shaft member. The magnet includes a first magnet facing the first yoke pieces in a radial direction of the shaft member and a second magnet facing the second yoke pieces in the radial direction.
