ABSTRACT:

FIELD OF THE INVENTION
The present invention relates to a bicycle frame and, more particularly, to a frame that can damp the vibration caused in the frame when a bicycle is travelling on a rough road.
BACKGROUND OF THE INVENTION
Bicycles are popular for transportation because they are inexpensive, easy to park, do not consume fossil fuels and do not pollute the environment. Consequently bicycle riding is both a leisure and competitive sport as well as a primary means of transportation in many parts of the world.
The frame, a basic component of the bicycle, is typically rigid, with wheels rotatably attached to the ends of the frame. In this configuration, the bicycle will inevitably vibrate and transmit the vibrations and shocks to the rider when the bicycle is travelling on a rough road. Consequently, numerous shock absorbing devices have been developed to isolate the shock and vibration from the rider.
SUMMARY OF THE INVENTION
The object of the present invention is to provide a frame that can effectively damp the shocks and vibrations generated when a bicycle is travelling on a rough surface.
