Abstract: A fastening device for a bicycle includes a fixed assembly and a fastening assembly. The fixed assembly is fixedly mounted to the frame of the bicycle, and the fastening assembly is used for supporting an article. The first moveable socket and the second moveable socket of the fastening assembly are snapped into the first fixed holder and the second fixed holder of the fixed assembly correspondingly, so that the fastening assembly and the supported article are detachedly mounted to the frame of the bicycle. The fastening device for a bicycle can facilitate the disengaging and engaging of the article, prevent wear of the surface of the article, and enhance the fixing strength of the fastening assembly.

Abstract: A bicycle fastener includes a fixing assembly (1) and a fastener assembly (3). The fixing assembly (1) is fixedly mounted to the frame (5) of the bicycle, and the fastener assembly (3) is used for supporting an article. The first moveable seat (31) and the second moveable seat (32) of the fastener assembly (3) are snapped into the first fixing seat (11) and the second fixing seat (12) of the fixing assembly (1) correspondingly, so that the fastener assembly (3) and the supported article are detachedly mounted to the frame (5) of the bicycle. The bicycle fastener can facilitate the disengaging and engaging of the article, prevent wear of the surface of the article, and enhance the fixing strength of the fastener assembly.

Abstract: A carrying trailer for use with bicycles includes a spine, a plurality of branch members and a wheel. The spine has a connecting portion at one end thereof which is adapted to couple to a bicycle. Each branch member has a ring and a supporting arm. The ring is rotatably mounted around the spine. One end of the supporting arm is fixed to an outer radial surface of the ring and the other end thereof extends away from an axis of the ring, with the supporting arm extending in a radial direction of the ring. The wheel pivotably couples to the other end of the spine. Consequently, positions of the branch members on the spine can be adjust to form a loading plane, or to stack the supporting arms of the branch members up at the same side of the spine for reducing storage space.

Abstract: The bicycle trailer in accordance with an aspect of the present invention includes a carrying frame, two adjusting modules and two wheels. The carrying frame is adapted to hold objects. The adjusting modules mounted at two opposite sides of the carrying frame respectively. Each adjusting module includes a pivoting member pivotably coupled to an corner of the carrying frame, an adjusting member movably mounted on the carrying frame to move close to or away from the pivoting member and a connecting bar with two ends thereof respectively fixed to the adjusting member and one end of the pivoting member. The two wheels are coupled to the other ends of the pivoting members of the two adjusting modules respectively. Consequently, positions of the wheels relative to the carrying frame are adjustable through the adjusting modules, so that the bicycle trailer can be adapted as a baggage barrow when separated from a bicycle.

Abstract: A carrying apparatus for use with cycle comprises a box, a bag and a seat. Said box has a first case, a second case, and two connectors. The first case has a side-wall providing an opening, and two end-walls connecting to two opposite edges of the side-wall and being two opposite sides of the box; the second case is movably received in the first case to reveal or conceal the opening thereof; and the two connectors pivotably couple to the two end-walls respectively. Said bag has at least one window, with a pair of join members being arranged and adjacent to two opposite edges of the bag for adhering to or engaging with each other and one of the two opposite edges being linked to the box. Said seat connects with the two connectors of the box for coupling the box to a cycle.
