Abstract: 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.

Abstract: A bicycle pedal is provided that includes a pedal axle, a pedal body, a first clamping member, a second clamping member, and a biasing structure. The pedal axle defines a rotational axis. The pedal body is rotatably supported on the pedal axle. The first clamping member is movably coupled to the pedal body between a first clamping position and a first open position. The second clamping member provided is on the pedal body. The second clamping member is configured to clamp a cleat between the first clamping member and the second clamping member in a clamping state where the first clamping member is in the first clamping position. The biasing structure includes at least one magnet to bias the first clamping member toward the first clamping position.
