  • Patent number: 11345433
    Abstract: A brake control device includes an electronic controller that is configured to control a braking unit that is configured to brake at least one of a plurality of rotating bodies of a human-powered vehicle. The electronic controller is configured to control the braking unit upon determining an ABS control is performed to decrease a braking force of a first rotating body included in the plurality of rotating bodies so that a braking force of a second rotating body, which is different from the first rotating body and included in the plurality of rotating bodies, is increased by a force that is different from hydraulic pressure.

  • Patent number: 11150351
    Abstract: A brake control device includes an electronic controller that executes an ABS control on a rotating body of a human-powered vehicle. The electronic controller executes the ABS control based on a relationship between a first speed and a second speed related to the human-powered vehicle. The first speed includes a speed of the human-powered vehicle based on information of a traveling environment. The second speed includes a speed of the human-powered vehicle based on a rotational speed of the rotating body.

  • Patent number: 11142279
    Abstract: A brake control device includes an electronic controller that controls a brake unit configured to brake a rotation body of a human-powered vehicle. The electronic controller limits ABS control in a case where a first predetermined condition for executing ABS control and a second predetermined condition for limiting ABS control are satisfied. The second predetermined condition is set based on limitation information that differs from information related to a traveling speed of the human-powered vehicle.

  • Patent number: 7892122
    Abstract: A derailleur for a bicycle comprises a base member, a movable member for supporting a chain guide, a linkage mechanism coupling the base member to the movable member, an electrically operated actuating element, and a power storing mechanism. Moving the actuating element causes the movable member to move laterally. A first portion of the power storing mechanism is disposed in a first power transmission path between the actuating element and the movable member, and a second portion of the power storing mechanism is disposed in a different second power transmission path between the actuating element and the movable member. The actuating element comprises a first actuating member and a second actuating member. The first actuating member communicates force in the first power transmission path, the second actuating member communicates force in the second power transmission path, and the first actuating member moves relative to the second actuating member.
