ABSTRACT:
The present invention provides a dual riding and driving tricycle in juxtaposing link, particularly for one that can be pedaled by two drivers in side-by-side coordination manner so that the drivers and tricycle will incline integrally without tumbling or overturning possibility; The main feature is that at least one articulation mechanism and a resilient tension mechanism are disposed between the primary bicycle body and auxiliary cycle body, wherein, said articulation mechanism serves in synergy an articulation parallelogram while said resilient tension mechanism counteract the deformation of the articulation mechanism to resume the stable equilibrium so that the integral of the primary bicycle body and auxiliary cycle body can automatically maintain harmonic coordination and stability when driving over bumpy road or corner turn.
