A push scooter is provided, including: a deck, a wheel, a seat mechanism, a footrest and an adjusting assembly, wheels being disposed at a front end and a rear end of the deck, the footrest being disposed at the front end of the deck, the seat mechanism being adjustably disposed on the deck by the adjusting assembly.

A limiting structure of a bicycle includes a handlebar, a rotating member, a front fork, and a frame. The frame is provided with a mounting portion. The handlebar is partially accommodated at one end of the mounting portion, and the front fork is partially accommodated at the other end of the mounting portion. The rotating member is accommodated in the mounting portion. Two ends of the rotating member are movably connected to the front fork and the handlebar, respectively. An annular movable groove is formed between an inner wall of the mounting portion and the rotating member. The front fork is provided with a first limiting block, and the first limiting block is movably accommodated in the movable groove. The frame further includes a second limiting block, and the second limiting block is fixedly accommodated in the movable groove.

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.

The present invention relates to a compression assembly for allowing an inner post to be securely disposed in an outer post, such as a bicycle seat post. The compression assembly comprises a connecting assembly for connecting the compression assembly to the inner post, an expanding component, and an expander component attached to a surface of the expanding component. Actuating the expander component in a first mode may cause the expanding component swell, and actuating the expander component in a second mode may cause the expanding component shrink. The first mode may prevent the inner post from being removed from the outer post. The second mode may allow the inner post to be removed from the outer post.

An adjustable height seat post including supporting means connectable to a bicycle frame, a quill associated with said supporting means and having a head suitable to clamp rails of a bicycle saddle, hydraulic adjusting means, associated with said supporting means, for lifting or lowering said quill in a desired position selected by the user, said hydraulic adjusting means including a cylindrical chamber inside which a piston assembly is foreseen, and valve means, suitable to selectively open or close an hydraulic path through said piston assembly for selectively lock or unlock the position of said piston assembly relative to said cylindrical chamber, and the valve means comprise at least a valve body, associated with said piston assembly, which is selectively rotatable from an open position, in which the hydraulic path is open, to a closed position in which the hydraulic path is closed.

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 head assembly is disclosed. The assembly includes a housing coupled to a seat post, the housing including a cylindrical bore, and a first and second threaded chamber. A rotatable core is inserted into and rotates within the cylindrical bore, the rotatable core including a seat rail clamp assembly to fixedly clamp a set of seat rails and provide independent adjustment of a fore-aft location of the seat without affecting a pitch of the seat. The assembly additionally includes a first threaded member that threads into the first threaded chamber, contacts the rotatable core, and adjusts the pitch of the seat without affecting the fore-aft location of the seat. The assembly also includes a second threaded member that threads into the second threaded chamber, contacts a different portion of the rotatable core, and provides a physical hard stop against a change in the pitch.
