Abstract: A bicycle derailleur comprises a base member, a chain guide, a motor unit, and a linkage structure. The base member has at least one first link-pin-receiving opening. The motor unit has at least one second link-pin-receiving opening. The linkage structure comprises at least one link member and at least one link pin. The at least one link member is configured to movably couple the chain guide to the base member. The at least one link member has at least one third link-pin-receiving opening. The at least one link pin is configured to pivotally couple the at least one link member to the base member about at least one link pivot axis. One of the at least one link pin is configured to extend through the at least one first link-pin-receiving opening, the at least one second link-pin-receiving opening, and the at least one third link-pin-receiving opening.

Abstract: An electric front derailleur is basically provided with a base, a chain guide, a linkage and an electric motor unit. The base is configured to be mounted to a bicycle. The chain guide is configured to guide a chain. The linkage movably couples the chain guide to the base in a forward-rearward direction to move the chain guide between a retracted position and an extended position in a mounted state where the base is mounted to the bicycle. The electric motor unit is supported on the base and operatively coupled to the linkage to move the chain guide between the retracted position and the extended position. The electric motor unit is arranged at least partly closer to the bicycle than the chain guide.

Abstract: A bicycle operating device is basically provided with a base member, a first operating member and an attachment. The base member has an interior space that is configured to receive an operating unit. The first operating member is configured to move along a first operating path from a rest position to an operated position to operate the operating unit when the operating unit is disposed in the interior space. The attachment blocks the first operating path to prevent movement of the first operating member from reaching the operated position.

Abstract: A shifting system for a human-powered vehicle comprises a controller. The controller is configured to receive a driving torque and a cadence of the human-powered vehicle from at least one sensor. The controller is configured to determine a permitted shift timing based on the driving torque and the cadence. The controller is further configured to control a shift mechanism to perform a gear shift during the permitted shift timing in accordance with a permitted cadence range and a first threshold of the driving torque.

Abstract: A bicycle chain guide includes a base and a chain guide. The base is configured to be mounted to a bicycle that includes a solitary sprocket having a rotational center axis. The chain guide is disposed above the solitary bicycle sprocket in a mounted state where the base is mounted to the bicycle. The chain guide includes a first guide plate, a second guide plate, and a bridge. The first guide plate has a first guiding surface. The second guide plate is closer to the base than the first guide plate and has a second guiding surface facing the first guiding surface to define a chain guiding slot between the first guiding surface and the second guiding surface. The bridge connects the first guide plate and the second guide plate.
