An angle-laminated composite tube with double layer of materials uses an inner layer material and an outer layer material with different functional properties. The two materials are cut into a plurality of slices in a specific shape. They are laminated alternately with a mismatching angle inside a mold with a specific angle to form a laminated assembly. Finally, a hot press is used to cure the laminated assembly into a structure with an inner layer, an outer layer, and an interlacing layer. The slice shape of the inner layer material and the outer layer material is specifically designed so that the inner layer, the outer layer, and the interlacing layer receive an even pressure during the curing process, rendering desired densities in the layers. The angle-laminated composite tube can achieve a high structural strength, with the inner and outer parts satisfying different functional needs.

An improved vibration suppressed bicycle structure includes a frame and a handle set that have ceramic piezoelectric elements located thereon to couple with passive and active control energy consuming mechanisms to convert the vibration energy of the bicycle body into electric energy, which is consumed in heat or gathered for active control use. The invention can absorb vibration energy of the bicycle to enhance structural performance, reduce vibration, and give bicycle riders more comfort over long distance rides and improved maneuverability.
