Abstract: A hydraulic reservoir of a human-powered vehicle comprises a reservoir structure and a bleeding plug. The reservoir structure includes a reservoir chamber, a bleeding port, and a connecting port. The bleeding port is configured to be in communication with the reservoir chamber. The bleeding port has a bleeding-port inner diameter. The connecting port is configured to connect the reservoir chamber and a hydraulic chamber. The hydraulic chamber is at least partially defined by a piston. The reservoir structure includes an intermediate port through which a fluid is to flow from the connecting port to the bleeding port when bleeding the hydraulic reservoir. The intermediate port has an intermediate-port inner diameter smaller than the bleeding-port inner diameter. The bleeding plug is configured to be attached to the bleeding port.

Abstract: A piston assembly is provided for a human-powered vehicle. The piston assembly includes a main body and a primary seal. The main body is configured to be movable from a rest position to an actuated position along an actuation direction in a cylinder bore. The primary seal includes a primary seal body arranged on the main body. The primary seal body is made of a resin material. The primary seal body has a primary lip portion configured to be in contact with the cylinder bore in an arranged state where the piston assembly is arranged in the cylinder bore. The primary seal further includes a biasing part configured to be in contact with an outer circumferential surface of the main body to outwardly bias the primary lip portion of the primary seal body in the arranged state.

Abstract: A hydraulic operating device for a small vehicle including a bicycle is basically provided with a base member, an operating member, a piston, a handlebar fixing structure and a hydraulic reservoir tank. The base member includes a cylinder having a cylinder bore. The operating member is pivotally coupled to the base member about a pivot axis. The piston is movably disposed in the cylinder bore and operatively coupled to the operating member to move the piston within the cylinder bore. The handlebar fixing structure is coupled to the base member. The handlebar fixing structure defines a handlebar arrangement area. The hydraulic reservoir tank has a hydraulic fluid chamber fluidly connected to the cylinder bore. The hydraulic reservoir tank at least partially overlaps the handlebar arrangement area as viewed in a pivot axis direction parallel to the pivot axis of the operating member.

Abstract: A bicycle transmission apparatus comprises a base member, a first transmission member, a second transmission member, a first coupling member, a first guide structure, a switching device, and a transmission controller. The switching device is configured to switch a position of the first transmission member relative to the base member in an axial direction between a first axial position and a second axial position. The transmission controller is configured to control the switching device and the first guide structure so as not to change a first engagement state of the first coupling member from one cogwheel to another adjacent cogwheel among first cogwheels when the first transmission member moves relative to the base member in association with a movement of the first guide structure relative to the base member to change a second engagement state of the first coupling member from one cogwheel to another adjacent cogwheel among second cogwheels.

Abstract: An operating device for a human-powered vehicle comprises a base, a piston, an operating member, an intermediate member, and a mounting structure. The base includes a hole. The piston is movably provided in the hole. The operating member is pivotally coupled to the base about a first pivot axis. The intermediate member is pivotally coupled to the base about a second pivot axis to transmit a pivotal movement of the operating member to the piston. The mounting structure is configured to couple the base and a handlebar of the human-powered vehicle. The mounting structure defines a mounting axis extending along the handlebar in a mounting state where the mounting structure couples the base and the handlebar. The first pivot axis is closer to the mounting axis than the second pivot axis in a perpendicular direction perpendicular to the mounting axis as viewed along the first pivot axis.

Abstract: An operating device comprises a base member and an operating member. The base member includes a base body and a mounting part. The mounting part includes a mounting contact surface contactable with a tubular part of the human-powered vehicle in a mounting state where the mounting part couples the base body to the tubular part of the human-powered vehicle. The base member includes a first contact surface and a second contact surface. The first contact surface is contactable with the tubular part of the human-powered vehicle in the mounting state. The first contact surface is spaced apart from the mounting contact surface in an axial direction. The second contact surface is contactable with the tubular part of the human-powered vehicle in the mounting state. The second contact surface is spaced apart from the mounting contact surface and the first contact surface in the axial direction.

Abstract: An operating device for a handlebar steered vehicle is basically provided with a base member, an operating member and a handlebar fixing structure. The base member includes a support abutment arranged to contact an outer surface of a handlebar while the operating device is in an installed state. The operating member is pivotally coupled to the base member about a pivot axis. The handlebar fixing structure is coupled to base member. The handlebar fixing structure defines a handlebar arrangement area extending along a handlebar axis. The support abutment being spaced from the handlebar receiving area of the handlebar fixing structure in a handlebar axis direction parallel to the handlebar axis by an axial width with a range from ten millimeters to thirty millimeters.

Abstract: A bicycle drive unit comprises a housing configured to be mounted to a first base member. The housing includes a first wall at least partly defining an internal space to at least partly accommodate a bicycle crank having a crank rotational axis. The first wall includes a first transmitting surface disposed to at least partly face upward in a bicycle upright state where the crank rotational axis horizontally extends and the housing is mounted on the first base member. The first transmitting surface is configured to face a first receiving surface of the first base member to transmit an upward force from the housing to the first base member. The first transmitting surface being at least partly disposed below the crank rotational axis in the bicycle upright state.
