Abstract:
1. An improved vibration suppressed bicycle structure for a bicycle frame, the bicycle frame comprising: a upper tube, a head tube coupling with one end of the upper tube, a seat tube coupling with other end of the upper tube, two rear upper forks coupling with a upper side of the seat tube, two rear lower forks coupling with distal ends of the rear upper forks, a hub coupling with the two rear lower forks and the seat tube, a lower tube bridging the head tube and the hub, and a handle set movably coupled with the head tube; wherein the structure, including the upper tube, the lower tube, the head tube, the seat tube, the two rear upper forks, the two rear lower forks and the handle set, has ceramic piezoelectric elements located on high strain areas to form active and passive mechanisms of a damping effect to absorb a portion of vibration energy of the bicycle to reduce vibrations.
