A fluid cylinder assembly for a hydraulic actuation system for a bicycle is provided. The fluid cylinder assembly includes a fluid cylinder. The fluid cylinder includes a housing and a piston that is movable within the housing. The fluid cylinder assembly also includes a force applicator connected to the piston of the fluid cylinder, a support, and an actuator pivotably attached to the support. The actuator is operatively connected to the piston of the fluid cylinder via the force applicator, such that the actuator is configured to translate the piston from a first position to a second position when the actuator is actuated. The fluid cylinder is attachable to a handlebar of the bicycle, such that part of the fluid cylinder is positioned within the handlebar and at least part of the force applicator is radially outer relative to the handlebar.

An ABS disposition structure of a saddle riding vehicle includes a head pipe, a main frame, a pair of left and right center frames extending downward from a rear section of the main frame and having a pivot section by which a front end portion of a swing arm is pivotably supported, a cushion disposed at a center in a vehicle width direction, and an ABS modulator configured to perform ABS control, wherein, when seen in a side view, a central axis of the cushion is disposed to be offset from a center frame in a forward and rearward direction, and the ABS modulator is disposed between the cushion and the center frame in a vehicle width direction.

An adapter body is configured to be attached to a vehicle body in each of a first orientation in which a caliper body is coupled to the vehicle body via the adapter body in a first position corresponding to a first disc brake rotor having a first outer diameter, and a second orientation in which the caliper body is coupled to the vehicle body via the adapter body in a second position corresponding to a second disc brake rotor having a second outer diameter different from the first outer diameter. The indicator is configured to indicate an correspondence between an orientation of the adapter body and at least one of the first disc brake rotor and the second disc brake rotor.

The invention obtains a hydraulic pressure controller whose control of a braking force is suppressed from becoming unstable. The invention also obtains a hydraulic brake system that includes such a hydraulic pressure controller, and a bicycle. A hydraulic pressure controller 110 controls hydraulic pressure of a brake fluid that is at least supplied to a front-wheel braking section 17 of a bicycle 200, and includes: a base section that is formed with a channel, through which the brake fluid flows, therein; a valve that is attached to the base section and opens and closes the channel; and a coupling section that couples the base section to the bicycle 200. The coupling section is coupled to a turning section 10 of the bicycle 200, the turning section 10 turning about an axis of a head tube 1A.

A power-assist drive system for a vehicle (e.g., a bicycle) is provided. The system includes a drive unit assembly attached to a frame of a vehicle and a motor having an output shaft, and a drive gear rotatably associated with the output shaft. The system further includes a driven unit assembly including a driven gear configured to be attached to a wheel hub of the vehicle, and a brake disc coaxially attached to the driven gear. The drive gear may be configured to operably engage the driven gear to transmit power from the motor to the wheel hub. A brake caliper may be integrated with the drive unit assembly. The system may further include a battery and a speed controller configured to receive an input signal to selectively direct electrical power from the battery to the motor to drive the wheel via the drive gear and the driven gear.

A two-wheel vehicle suspension linkage, including a shock and a shock extension assembly, is provided. The shock may include first and second mounting axes operably connected to two linkage bodies. The shock may be positioned to provide linear resistance between the two linkage bodies having relative motion with respect to one another. The shock extension assembly may include a first extension body and a second extension body. Each of the first extension body and the second extension body may include a first mounting axis and a second mounting axis positioned with respect to one another in a non-parallel mounting orientation. The extension bodies may be pivotally connected to the suspension linkage so that the first mounting axis of the first extension body is collinear with the first mounting axis of the second extension body. The second mounting axis of the first extension body may be collinear to both the second mounting axis of the second extension body and to one of the shock mounting axes defining a non-effective shock damper axis.
