<p>A reinforced bicycle frame (10) is made from a fiber-reinforced material. The reinforced bicycle frame includes a head tube (11), a top tube (12) extending from the head tube, a down tube (13) extending from the head tube beneath the top tube, and at least one rib (14-19, 21, 31). The insides of the head, top and down tubes are communicated with each other in a way that the head, top and down tubes combinedly form a frame head (20) having an inner surface (201) defining a chamber (202). The rib has a connection end (171) connected with the inner surface (201) of the frame head (20) and a free end (172) located in the chamber (202), thereby enhancing the structural strength of the bicycle frame (10).</p> |
