Abstract: A collapsible handlebar for use on a bicycle includes a ferrule, two tubes and two beams. The ferrule is operable to hold a stem of a fork of the bicycle. Each of the tubes includes an internal end. Each of the beams includes a supportive end for supporting one of the tubes and a connective end pivotally connected to the ferrule. Thus, the beams are movable relative to each other between a close position and a distant position. The internal ends of the tubes are located near and connected to each other when the beams are in the close position.

Abstract: A light assembly mounted in recess of a seat post of a bicycle is provided with a push button moveably mounted on a mouth of the recess and including a bossed hole on a rear surface; a resilient conductor fastened in the bossed hole; a controller circuit fastened in the recess and including two spaced contacts spaced from the conductor in a non-depressed position, the contacts being electrically connected to the controller circuit; LEDs disposed on a front surface of the controller circuit facing the rear surface of the push button; and a battery mounted to a rear surface of the controller circuit and electrically connected to the contacts. A pressing of the push button electrically connects the conductor to the contacts so that an electric energy is supplied from the battery to the LEDs for illumination via the contacts, the conductor, and the controller circuit.

Abstract: A bicycle shock-absorbing assembly is composed of a connection rod, a position restricting nut, a coil spring, a dustproof jacket, a resilient locating ring, a front reinforcing member, and a rear reinforcing member. The bicycle shock-absorbing assembly is arranged such that it is capable of alleviating the impact force which is transmitted from the bicycle wheels to the top tube, the seat tube, and the down tube of the bicycle.

Abstract: A saddle mounting frame assembly includes a seat post, which consists of a master tube and an auxiliary tube welded to the master tube at one side, an upper clamping plate, a lower clamping plate having a hollow bottom shaft fitted into the master tube, a fastening device to fasten the upper and lower clamping plates together permitting them to be fastened to a saddle, an adjusting screw to fasten the fastening device to the auxiliary tube, a first shock absorbing element fitted into the master tube and stopped between a blocking plate inside the master tube and the bottom shaft of the lower clamping plate, and a second shock absorbing element fitted into the auxiliary tube to support the fastening device.

Abstract: A bicycle head tube assembly includes a connecting device connected between a handlebar lug thereof and a head tube thereof to absorb shocks, the connecting devices comprised of a soft covering and a stack of resilient steel plates covered within the soft covering, the resilient steel plates including a fixed steel plate at the top having two opposite ends welded to the lug and the head tube respectively, and stack of suspension steel plates alternatively welded to the lug or the head tube and having a respective free end spaced from the lug or the head tube at a distance.
