Abstract: A bicycle shifting apparatus comprises a shifting controller. The shifting controller is configured to control one of a front shifting device and a rear shifting device to change one of a front shift position and a rear shift position in response to a user input. The shifting controller is configured to control the other of the front shifting device and the rear shifting device to change the other of the front shift position and the rear shift position with a delay time period in conjunction with the one of the front shifting device and the rear shifting device in response to the user input. The shifting controller is configured to change the delay time period based on at least one of a gear ratio, the rear shift position, and a current rotational speed of a bicycle crank.

Abstract: A front derailleur basically includes a fixed member, a movable member, a driven link and a first link. The fixing member is configured to be fixed to a bicycle frame. The movable member is movably supported with respect to the fixed member. The driven link is operatively coupled to the movable member. The first link movably connects the movable member to the fixed member, and is adjustably coupled to the driven link in a fixed position by a fixing structure to establish a fixed rest position of the movable member with respect to the fixed member.

Abstract: An electrical bicycle derailleur includes a base member and a movable member movably arranged between a retracted position and an extended position. A linkage operatively couples the movable member to the base member. The linkage includes a first link member and a second link member. The first link member is disposed closer to the base member than the second link member. A motor unit is operatively coupled to the first and second link members to rotate the first and second link members. A linkage housing is configured to support the first and second link members and the motor unit. A first diameter of the first link member is different from a second diameter of the second link member and/or a first tooth number of the first link member is different from a second tooth number of the second link member.

Abstract: An electronic device includes a receiver, a computer memory device and a processor for calculating a human input force and/or a human input power that are inputted to a drive train of a human powered vehicle. The receiver receives first information with respect to torque applied to the drive train, and receives at least one of second information with respect to a gear engagement state and third information with respect to a crank rotational speed. The computer memory device has prestored correction factors with respect to the gear engagement state. The processor calculates the human input force based on the first information, the second information and at least one of the prestored correction factors, and/or calculates the human input power based on the first information, the second information, the third information, and at least one of the prestored correction factors.

Abstract: A bicycle shifting control apparatus comprises a transmission controller configured to control a guide actuator of a derailleur to move a chain guide of the derailleur between a plurality of shift positions in response to an input shifting signal. The transmission controller is configured to control, in a shifting operation of the chain guide between adjacent two shift positions of the plurality of shift positions, the guide actuator to temporarily decelerate the chain guide at a deceleration position defined between the adjacent two shift positions so that the bicycle chain engages with and/or disengages from one of the sprockets having a shift assist structure prior to completion of the shifting operation of the chain guide.
Abstract translation: 一种自行车变速控制装置，包括：变速器控制器，被配置为响应于输入换档信号，控制拨链器的引导致动器，以在多个换档位置之间移动拨链器的链条导轨。 变速器控制器被配置为在链轮导向件在多个换档位置的相邻两个换档位置之间的换档操作期间控制引导致动器以在相邻的两个换档位置之间限定的减速位置暂时减速链条引导件，使得 自行车链条在链条引导件的换档操作完成之前与具有换档辅助结构的链轮之一接合和/或脱离啮合。
