ABSTRACT:
A bicycle frame of the present invention is formed as follows.
First, the worker puts and bonds a pipe made by fibre reinforced plastics around a cylindrical projecting part of a lug made by thin wall thickness light alloy.
Next, the worker covers a joining part of the said projecting part of a lug and pipe made by fibrer reinforced plastics by sheet molding compound, (hereinafter it is called "SMC").
Last, the joining part of the projecting part of a lug and the pipe covered by said SMC is put in a molds for compression molding.
As the SMC consists of required quantity of plastics and chopped fibre same as filament comprised in the pipe made by fibre reinforced plastics, bonding of the pipe made by fibre reinforced plastics and said SMC is very good. Consequently, the joining strength of the pipe and lug is very strong in the present invention.
