Abstract: A manufacturing method of a bicycle unit has the following steps. In a pressing step: press metal sheets to form casing parts being overlappable. In an abutting step: abut the casing parts to form an abutting line. In a connecting step: connecting the two casing parts along the abutting line to form a motor mount prestructure having side plates and a motor-installation space formed therebetween. A prestructure of a bicycle frame is thereby made. In a motor mount forming step: cut the two side plates of the motor mount prestructure in compliance with a pre-determined motor system so as to form a bicycle frame unit with a motor mount.

Abstract: A bicycle frame unit for constructing a bicycle frame has two half casing parts and an annular supporting element. The annular supporting element is connected between the half casing parts and has a connecting hole for matching an outer contour of an external post. A gap is formed between the half casing parts and the annular supporting element, and a connecting material fills the gap and connects the half casing parts and the annular supporting element. A manufacturing method of the bicycle frame unit is also provided.

Abstract: A method for forming a bicycle frame component made of thermoplastic composite laminates has: a shell forming step: manufacturing multiple shells by compression molding; an overlapping step: overlapping two corresponding connecting margins of each two of the multiple shells to form an overlapping section of the two of the multiple shells and deploying a supporting unit within the multiple shells for supporting; a hot compressing connection step: heating and compressing the multiple shells to diffuse polymers of the multiple shells and to turn the multiple overlapping sections into multiple fusion areas for connection; a supporting unit removal step: removing the supporting unit disposed within the bicycle frame component.
