Abstract: A wheel rim includes two annular sidewalls and a main connecting wall. The main connecting wall has two ends connected respectively and fixedly to radial inner ends of the sidewalls, and opposite radially inner and outer surfaces. The radially inner surface faces the hub, and has two axial surface portions and a middle surface portion that are preferably concaved toward the tire. The radially outer surface has two axial surface portions and a middle portion. The axial surface portions of the radially inner and outer surfaces define two force-bearing areas having a plurality of mounting holes. The middle surface portions of the radially inner and outer surfaces define a weight-reducing area having a thickness smaller than a thickness of the force-bearing areas. The force-bearing areas and the weight-reducing area are arched.

Abstract: A wheel rim includes a rim body and a plurality of anchor members. The rim body includes annular left and right side walls, an annular connecting wall interconnecting the left and right side walls, and annular left and right confining ribs extending respectively from the radial inner ends of the left and right side walls toward each other to define a mounting space among the left and right side walls, the connecting wall, and the confining ribs. The confining ribs define an opening communicated with the mounting space. The anchor members are disposed fixedly within the mounting space. Each of the anchor members has a bottom wall abutting against the confining ribs and having a first mounting hole which is adapted to permit extension of a respective one of the spoke units therethrough.

Abstract: A lightweight wheel rim includes a pair of annular side walls, an annular inner wall, and two annular angle elements. The angle elements are disposed respectively at two opposite sides of the inner wall. Each of the angle elements has two opposite sides that are formed respectively and integrally with the inner wall and a radial inner end of a corresponding one of the side walls, and a plurality of alternately arranged mounting portions and dented portions. Each of the mounting portions has a mounting hole for extension of a spoke unit therethrough.

The intermediate part has a vaulted portion, which is vaulted radially, and is formed with spoke mounting holes, which are distributed between the vaulted portion and the corner parts.

Abstract: A bicycle wheel includes an annular wheel rim and inner and outer tire members. The wheel rim has two outer side walls spaced apart from each other, two inner side walls disposed between the outer side walls, and a base wall interconnecting radial inner ends of the outer and inner side walls. The outer tire member has two opposite longitudinal edges engaging radial outer ends of the outer side walls, respectively, and cooperates with the wheel rim to confine a first inflation chamber. The inner tire member is disposed within the first inflation chamber between the inner side walls of the wheel rim, and is mounted on the base wall. The inner tire member confines a second inflation chamber and abuts against the inner side walls when inflated.
