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.

A telescopic apparatus for a human-powered vehicle comprises a first hydraulic chamber, a second hydraulic chamber, a valve member, a cam member, and an actuator. The second hydraulic chamber is configured to be in fluid communication with the first hydraulic chamber. The valve member is configured to control a fluid communication between the first hydraulic chamber and the second hydraulic chamber. The cam member is rotatable about a rotational axis to move the valve member in a movement direction. The actuator is configured to rotate the cam member. The actuator includes an output shaft rotatable about an actuation rotational axis. The actuation rotational axis is offset from the rotational axis as viewed in the movement direction.

A bicycle frame including a down tube, a saddle tube, and a top tube is disclosed. The top tube comprises a first section which, starting from the saddle tube, is oriented in an ascending orientation. Thereby, a space between the down tube, the saddle tube, and the top tube is enlarged, so that the bicycle frame can be carried on a person's shoulder in a more convenient manner.

A seatpost assembly, including a first seatpost portion, a second seatpost portion axially displaceable relative to the first seatpost portion along an axial axis, and an engagement element with a circumferential coil portion having a first termination and a second termination. The engagement element may be elastically deflected in a relaxing direction toward an engaged orientation to provide restraint of the axial displacement at a restraining interface with one of the first and second seatpost portions; and in a deflecting direction toward a released orientation for reduced restraint. The engagement element has an axially maintained engagement with the other one of the first seatpost portion. Where one of: (i) the released orientation corresponds to a radially outwardly expanded orientation of the engagement element relative to the deflected position; and (ii) the released orientation corresponds to a radially inwardly contracted orientation of the engagement element relative to the deflected position.

A seat post assembly includes a seat post that is electrically adjustable in height. The adjustability may be based on one or more pressures sensed by one or more sensors within the seat post assembly, respectively. The disclosed seat post assembly includes an electronics module. The electronics module may be carried under the seat or saddle and may include a pressure sensor or pressure sensor circuitry.

A liftable seatpost includes an outer tube, an inner tube, and a bushing. A protrusion is provided at the outer surface of the inner tube. The bushing is disposed between the inner and outer tubes and includes an upper sleeve and a lower sleeve. The upper sleeve has an upper baffle ring with a first engaging portion. The lower sleeve has a lower baffle ring with a second engaging portion engaged with the first engaging portion of the upper sleeve. The edges of the upper and lower sleeves are abutted against each other, and the outer surface of the upper baffle ring is flushed with the outer surface of the lower baffle ring. Thus, the position corresponding to the bushing will not protrude too much and affect the appearance, and the stress transmitted from the protrusion of the inner tube to the upper sleeve can be effectively distributed.

A rotation locking device includes a locking module and at least one engaging member. The at least one engaging member is rotatably coupled to the locking module. The locking module is configured to engaging and disengage the at least one engaging member, thereby refraining the at least one engaging member from rotating relative to the locking module.
