Abstract: A bicycle bar end attachment includes a main body, a shoe, a compression member, a rotation member, a transmission structure and a fixing structure. The main body is insertable into a bicycle handlebar, and includes a first threaded portion. The shoe is located between an inner surface of the handlebar and the main body. The compression member includes a second threaded portion engaged with the first threaded portion and a first pressing surface contacting one end of the shoe. The rotation member includes an exposed portion accessible from outside the handlebar and a second pressing surface contacting the other end of the shoe. The transmission structure transmits rotation of the rotation member to the compression member. The fixing structure holds the shoe between the compression member and the rotation member, and moves the shoe in a radial direction of the handlebar to fix the main body to the handlebar.

Abstract: An electric bicycle derailleur control system is basically provided with a derailleur, a detecting device and a controller. The derailleur includes a chain guide and an electrical actuator. The chain guide is configured to displace a bicycle chain. The electrical actuator is operatively coupled to the chain guide to displace the chain guide. The detecting device is configured to detect information related to a reaction force of the bicycle chain. The controller is configured to control the electrical actuator in accordance with detected information.

Abstract: An electric power storage holder is inserted in a seat tube of a bicycle frame and holds an electric power storage member. The electric power storage holder includes a restricting section and a holding section. The restricting section contacts an end edge of an open end section of a seat tube to restrict axial movement of the holder in one of axial directions of the seat tube, the one of the axial directions being a direction in which the seat tithe extends. The holding section holds the electric power storage member.

Abstract: An electric derailleur motor unit includes a base member, a motor, an output shaft, and a drive train. The motor is mounted to the base member. The motor has a motor shaft rotatable about a first rotational axis. The output shaft is rotatable about a second rotational axis. The drive train is operatively disposed between the motor shaft of the motor and the output shaft. The drive train includes an anti-backdriving device. The anti-backdriving device is configured to transmit rotation of the motor shaft of the motor in both rotational directions about the first rotational axis to the output shaft. The anti-backdriving device is further configured to prevent the output shaft from rotating in both rotational directions about the second rotational axis while the output shaft receives an external rotational torque from outside of the electric derailleur motor unit.

Abstract: A bicycle electric actuator unit basically has a housing, an electric drive part and a cable holding member. The electric drive part is disposed in the housing and electrically connected to an electrical cable. The cable holding member is provided at an outer surface of the housing to hold a portion of the electrical cable. The bicycle electric actuator unit can be for example part of an electric bicycle component such as an electric front derailleur or an electric rear derailleur.

Abstract: A bicycle electric power source assembly comprises a tubular member, an electric power source member and a restricting member. The tubular member includes an inner peripheral surface, an outer peripheral surface and a through hole that passes through the tubular member between the inner peripheral surface and the outer peripheral surface. The electric power source member is disposed inside the tubular member. The electric power source member includes a restriction accepting part. The restricting member is disposed in the through hole. The restricting member includes a restricting part that engages with the restriction accepting part to restrict relative movement of the electric power source member with respect to the tubular member in an axial direction of the tabular member.
