    • The present invention relates to a twin-frame bicycle, particularly to one that can be pedaled by two riders in side-by-side coordination so that the riders and the twin-frame bicycle will incline integrally without tumbling or overturning. At least one articulation mechanism is disposed between a primary bicycle body and an auxiliary bicycle body, wherein the articulation mechanism serves in synergy an articulation parallelogram and a resilient tension mechanism counteracts the deformation of the articulation mechanism to maintain equilibrium. A front wheel and a rear wheel of the primary bicycle body and an auxiliary wheel of the auxiliary bicycle body form a triangular area, and the riders' center of gravity of the twin-frame bicycle is within the triangular area, which keeps the riders and the twin-frame bicycle stable without any possibility of tumbling.
    • 双框架自行车技术领域本发明涉及一种双框架自行车,特别涉及一种可以由两个乘坐者并排踩踏的自行车,使得车手和双框架自行车整体倾斜,而不会翻滚或翻倒。 至少一个关节运动机构设置在主自行车主体和辅助自行车主体之间,其中所述关节运动机构协同作用是关节平行四边形和弹性张力机构抵消所述关节运动机构的变形以保持平衡。 主自行车主体的前轮和后轮以及辅助自行车主体的辅助轮形成三角形区域,并且双框架自行车的骑手的重心在三角形区域内,这保持了骑手和 双框架自行车稳定,没有任何翻滚的可能。
