The invention discloses a bicycle rim, a bicycle wheel and a bicycle, the bicycle rim is provided with an annular tire mounting part for mounting a tire and an annular spoke mounting part for mounting spokes, the annular tire mounting part and the annular spoke mounting part are relatively fixed, N spoke mounting parts which are circumferentially and uniformly arranged at intervals are arranged on the annular spoke mounting part, and N is a natural number greater than 3; the inner circumferential wall of the annular spoke mounting part is arranged in a concave-convex mode in the circumferential direction, N inwards-concave parts and N inwards-convex parts are formed, the concave-convex direction is arranged in the radial direction, the inwards-concave parts are filled with reinforcing bases so that the inner circumferential wall of the annular spoke mounting part can be of a rotation structure, and the spoke mounting part corresponds to the inwards-concave parts in position. The bicycle rim has the advantages that the fixing strength between the spokes and the rim is enhanced through the reinforcing structure, the inner circumferential wall of the annular spoke mounting part is of a rotary structure through the reinforcing seat, the smoothness of the inner circumferential wall of the annular spoke mounting part is improved, and the spokes are avoided from spraining the feet.

    本发明公开了自行车轮辋、自行车车轮及自行车,自行车轮辋具有相对固定的用于安装轮胎的环状轮胎安装部和用于安装辐条的环状轮辐安装部,该环状轮辐安装部上设有N个周向均匀间隔布置的辐条安装部,该N为大于3的自然数;该环状轮辐安装部内周壁周向凹凸布置且形成有N个内凹部和N个内凸部,该凹凸方向沿径向布置,该内凹部处填补有补强座以使环状轮辐安装部内周壁呈回转结构,该辐条安装部所处位置对应内凹部。它具有如下优点:通过补强结构增强辐条和轮辋之间的固装强度,通过补强座使环状轮辐安装部内周壁呈回转结构,改善了环状轮辐安装部内周壁平顺度,避免辐条蹩脚。
