Abstract: A bicycle hydraulic operating device basically has a base member, an operating member, a piston and a connecting rod. The base member includes a cylinder bore and a reservoir tank. The operating member is pivotally mounted to the base member to pivot about a pivot axis. The piston is movably disposed in the cylinder bore of the base member along a cylinder axis of the cylinder bore. The connecting rod operatively couples the operating member to the piston. The reservoir tank is arranged to overlap the connecting rod as viewed in a direction parallel to the pivot axis of the operating member. The reservoir tank is arranged to at least partly offset from the cylinder bore in a direction parallel to the cylinder axis.

Abstract: A bicycle operating device comprises a base member, an operating member, and a hydraulic unit. The base member comprises a first end portion, a second end portion, and a gripping portion. The gripping portion is provided between the first end portion and the second end portion. The operating member is movably mounted to the base member from a rest position toward an operated position. The hydraulic unit is provided at one of the base member and the operating member. The hydraulic unit comprises a hydraulic cylinder and a piston. The hydraulic cylinder includes a cylinder bore. The piston is arranged in the cylinder bore. The piston is configured to be pulled from an initial position to an actuated position in response to a movement of the operating member from the rest position toward the operated position to supply a hydraulic pressure toward at least one bicycle component.

Abstract: An operating device is provided for a human-powered vehicle. The operating device basically includes a base, a first operating member, a first electric switch, a first load generator and an operating load adjuster. The first operating member is movably arranged with respect to the base. The first electric switch is provided to the base and arranged to be activated by movement of the first operating member. The first load generator is configured to generate an operating load applied to the first operating member. The operating load adjuster is configured to adjust a transition of the operating load from a first load transition to a second load transition different from the first load transition.

Abstract: An electric device for a human-powered vehicle comprises an accommodating structure. The accommodating structure includes a main body, an attachment member, and a power-supply accommodating part. The attachment member is configured to be attached to the main body. The power-supply accommodating part is provided at least one of the main body and the attachment member so as to accommodate a power supply, the power-supply accommodating part including an insertion opening and a first inner surface. The first inner surface extends along a reference plane and having a first outline defining a first area as viewed in a direction perpendicular to the reference plane. The insertion opening extends along an insertion opening plane non-parallel to the reference plane. The insertion opening has an opening outline defining an insertion opening area as viewed in a direction perpendicular to the insertion opening plane. The first area is larger than the insertion opening area.

Abstract: A bar-end device assembly is provided for a tube member of a bicycle. The bar-end device assembly has a base member that includes a mounting portion, a first shoe and a second shoe. The mounting portion is configured to be mounted within an interior of a free end provided on the tube member. The first shoe is configured to engage the interior of the tube member as the mounting portion is mounted to the tube member with the first mounting shoe disposed on the mounting portion. The second shoe is configured to engage the interior of the tube member as the mounting portion is mounted to the tube member with the second mounting shoe disposed on the mounting portion. The first and second shoes have different configurations and are used one at a time to change an effective mounting dimension of the base member.

Abstract: A bicycle operating device comprises a base member, an operating member, a piston, and an electrical switch. The base member includes a first end portion to be mounted to a bicycle handlebar, a second end portion opposite to the first end portion, and a cylinder bore. The operating member includes a proximal end portion and a distal end portion. The proximal end portion is pivotally coupled to the base member about a pivot axis. The distal end portion is farther from the proximal end portion than the pivot axis. The piston is movably provided in the cylinder bore and operatively coupled to the operating member to move in the cylinder bore in response to a pivotal movement of the operating member. The electrical switch is provided at the second end portion. The electrical switch is farther from the distal end portion of the operating member than the pivot axis.
