ABSTRACT:
A new Method of Molding and Assembling a Bicycle Frame for offering a lighter, less expensive bicycle frame. The inventive device includes a frame assembly having a first half, a second half, and a front fork joint. In use, referring to FIG. 6, the first half 11 and the second half 13 are molded side by side. Then, after trimming, the first half 11 and the second half 13 are matingly joined together. The axle clamp housing 31 is then fixed to the drive wheel joint 30, and the pedal busing 22, the seat support bushing 42, and the front fork bushing 52 are installed, completing the frame assembly 12. A typical bicycle handle bar, pedals, drive wheel, front steer wheel, and seat are then assembled to the frame assembly 12, completing an overall assembly of the bicycle.
