Abstract: A bicycle power supply system is configured to be connectable to a plurality of battery units and configured to switch each of the plurality of battery units between a first state and a second state. The bicycle power supply system includes a memory device and an electronic controller. The memory device stores order information for switching the plurality of battery units from one of the first state and the second state to the other one of the first state and the second state in a predetermined order. The electronic controller switches the plurality of battery units from one of the first state and the second state to the other one of the first state and the second state in accordance with the order information in a case where the plurality of battery units is connected. The memory device is configured to changeably store the order information.

Abstract: A bicycle front derailleur including a chain guide; a linkage assembly; and a mounting bracket configured to mount the chain guide to a bicycle frame such that the chain guide is movable with respect to the mounting bracket. The mounting bracket includes at least one fixed portion adapted to receive a fastener to fix the fixed portion so that an axis of the fastener extends toward a bottom bracket hangar of the bicycle frame when the fixed portion is fixed to the bicycle frame via the fastener. The axis of the fastener is generally vertical.

Abstract: A bicycle drive unit comprises a housing configured to be mounted to a first base member. The housing includes a first wall at least partly defining an internal space to at least partly accommodate a bicycle crank having a crank rotational axis. The first wall includes a first transmitting surface disposed to at least partly face upward in a bicycle upright state where the crank rotational axis horizontally extends and the housing is mounted on the first base member. The first transmitting surface is configured to face a first receiving surface of the first base member to transmit an upward force from the housing to the first base member. The first transmitting surface being at least partly disposed below the crank rotational axis in the bicycle upright state.

Abstract: A bicycle tensioner apparatus comprises a first base member, a second base member, and a tensioner. The second base member is movably coupled to the first base member. The tensioner is configured to contact a driving-force transmitting member to apply tension to the driving-force transmitting member. The tensioner is coupled to both the first base member and the second base member. The tensioner is movable relative to at least one of the first base member and the second base member in response to a relative movement between the first base member and the second base member.

Abstract: A bicycle transmission apparatus comprises a base member, a first transmission member, a second transmission member, a first coupling member, a first guide structure, a switching device, and a transmission controller. The switching device is configured to switch a position of the first transmission member relative to the base member in an axial direction between a first axial position and a second axial position. The transmission controller is configured to control the switching device and the first guide structure so as not to change a first engagement state of the first coupling member from one cogwheel to another adjacent cogwheel among first cogwheels when the first transmission member moves relative to the base member in association with a movement of the first guide structure relative to the base member to change a second engagement state of the first coupling member from one cogwheel to another adjacent cogwheel among second cogwheels.
