ABSTRACT:
FIELD OF THE INVENTION
The present invention relates generally to a bicycle frame assembly, and more particularly to a bicycle frame assembly which looks like wood and which has a plurality of outstanding mechanical properties.
BACKGROUND OF THE INVENTION
The conventional bicycle frame made of a metal material is relatively heavy and can not be thus transported conveniently. The advanced bicycle frame is generally made of a carbon fiber composite material, a boron fiber composite material, etc., and is therefore relatively light in weight. In order to provide a bicyclist with a comfortable ride, especially on a bumpy road, the bicycle makers have made a great deal of effort to improve the shock-absorbing quality of the bicycle frame.
Generally speaking, the conventional bicycle frames of a metal or composite material have a frigid and monotonous appearance which is prone to undermine the sense perception of the bicyclist. In addition, conventional bicycle frames are made of fiber composite material impregnated with resin and are therefore inclined to produce static electrical charges resulting from friction.
SUMMARY OF THE INVENTION
It is therefore the primary objective of the present invention to provide a bicycle frame assembly with a wooden look, enhanced mechanical properties, and a user-friendly profile.
It is another objective of the present invention to provide a bicycle frame assembly incapable of producing static electricity.
It is still another objective of the present invention to provide a bicycle frame assembly capable of absorbing shock.
In keeping with the principle of the present invention, the foregoing objectives of the present invention are attained by a bicycle frame assembly comprising a main frame, a front fork, and a handlebar. The frame is formed of a cross tube, a seat tube, a down tube, an upper rear fork, a lower rear fork, a head tube, and a top tube. The front fork is fastened pivotally with the head tube of the main frame by a head bowl set. The handlebar is of a solid or hollow construction and is fastened pivotally with the head tube by a stem. All component parts of the bicycle frame assembly are covered with a wooden layer for enhancing the mechanical properties and the wooden look of the bicycle frame assembly.
The foregoing objectives, features, functions, and advantages of the present invention will be more readily understood upon a thoughtful deliberation of the following detailed description of the embodiments of the present invention with reference to the accompanying drawings.
