    Abstract: A bicycle rim includes a plurality of recesses defined in an inner periphery thereof and a through hole is defined through the rim and shares a common axis with the recess corresponding thereto. A plurality of spokes each have a threaded hole defined in a first end thereof which is fitted in one of the recesses and a plurality of bolts extend through the through holes and are threadedly connected to the threaded holes in the spokes. The through holes are small so that they do not reduce the structural strength of the rim and the end of each spoke is fitted in the recess to further position the spokes to the rim. A second end of each of the spokes is connected to a hub by extending a bolt through the hub and threadedly connected to the second end of each spoke.

    Abstract translation: 自行车轮辋包括限定在其内周中的多个凹部，并且穿过所述轮辋限定通孔，并且与其对应的凹部共享公共轴线。 多个辐条各自具有在其第一端中限定的螺纹孔，该螺纹孔装配在一个凹部中，并且多个螺栓延伸穿过通孔并螺纹连接到轮辐中的螺纹孔。 通孔很小，使得它们不会降低轮缘的结构强度，并且每个轮辐的端部装配在凹部中以进一步将轮辐定位到轮辋上。 每个辐条的第二端通过将螺栓延伸穿过轮毂并且螺纹连接到每个轮辐的第二端而连接到轮毂。

    Abstract: A bicycle wheel includes a rim with a plurality of holes defined therethrough and each hole receives an insertion section of a nut. The insertion section is enclosed by an inner periphery of the hole and an end surface of the insertion section is in flush with an inner periphery of the rim. A threaded hole is defined in the end surface of the insertion section. A plurality of spokes each have a threaded end at a first end thereof so as to be threadedly connected to the threaded hole of one of the nuts. A hooking end is connected at a second of each spoke so as to be connected to a hub.

    Abstract: A bicycle seat post protecting member which is utilized for protecting a bicycle seat post clamp from damaging a bicycle seat post is in the form of a ring which has a flexible characteristic. The ring is adapted to be disposed circumferentially between an inner periphery of the bicycle seat post clamp and an outer periphery of the seat tube. The ring defines inner and outer sides, and with the inner side at a proximal end thereof extending outside the outer side at a distal end thereof, and the ring includes an increased region of the inner side extended outside the outer side when the ring is being clamped by the bicycle seat post clamp.

    Abstract: A bicycle sprocket assembly comprises a first sprocket unit formed in one piece, a second sprocket unit formed in one piece and being hollow inside, and a third sprocket unit formed in one piece. The first sprocket unit includes at least one sprocket and a first protrusion. The second sprocket unit includes at least two sprockets with different outer diameter, a first recess formed in a side of the larger outer diameter sprocket and a second recess formed in a side of the smaller outer diameter sprocket. The third sprocket unit includes at least one sprocket and a second protrusion. In assembly, the first protrusion of the first sprocket unit engages with the first recess of the second sprocket unit and the second protrusion of the third sprocket unit engages with the second recess of the second sprocket unit.
