A bicycle wheel includes a reinforced annular rim that is coupled to a hub via a plurality of spokes. Specifically, the rim includes an outer portion and an inner portion fixedly coupled with the outer portion to form an annular hollow area between the inner and outer portions. Preferably, outer tubular spoke attachment portions are fixedly coupled to the outer portion at outer openings, while inner tubular spoke attachment portions are fixedly coupled to the inner portion at inner openings aligned with the outer openings to define spoke receiving spaces. Preferably, at least the first or second tubular spoke attachment portions are heat fused to the outer or inner portions, respectively. Each spoke receiving space is preferably at least partially threaded with the outer end portions directly threadedly coupled within one of the spoke receiving spaces. The central hub has the inner end portions of the spokes coupled thereto.
