Abstract: A reconfigurable toy vehicle is provided, the toy vehicle having: a first configuration and a second configuration; a main body portion, having a forward end, a rearward end and a pair of side members extending from the forward end to the rearward end; at least two telescopic wings attached to the main body portion; a retractable canopy movably secured to the main body portion, the retractable canopy being configured to cover a portion of the main body portion when the toy vehicle is in the second configuration; and a folding rear portion pivotally mounted to the main body portion, wherein movement of the folding rear portion causes the toy vehicle to transition between the first configuration to the second configuration.

Abstract: 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 having an elastic element is disposed between the primary bicycle body and the auxiliary bicycle body and counteracts the deformation of the articulation mechanism to maintain equilibrium.

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.

Abstract: A dual riding and driving tricycle in juxtaposing link comprises a primary bicycle body, an auxiliary cycle body and an articulation mechanism including a resilient tension mechanism. Primary bicycle body comprises a saddle sat by a primary rider, a front wheel controlled by a steering handle, a rear wheel and a pair of pedals to drive. Auxiliary cycle body comprises an auxiliary saddle sat by an auxiliary rider, an auxiliary wheel with a hub shaft located between hubs of front wheel and rear wheel in primary bicycle body and a pair of pedals to drive. Articulation mechanism comprises a left holding base, a right holding base and two parallel linking trough beams being disposed between both holding bases. Resilient tension mechanism comprises plural elastic elements connected on articulation mechanism respectively. Thereby, primary rider and auxiliary rider can independently tread respective pedals to drive synergistically.

Abstract: A device for connecting two bicycles to one another in a side-by-side relationship allows two riders to simultaneously use the bicycle and not have the view blocked by a rider directly in front of them. A steering bar insures that the front wheels of both bicycles are always pointed in the same direction so that, when connected, the joined bicycles both head in the same direction. Additional bars are connected between the two bicycles to provide a rigid connection between the bicycles. The rigid connection insures that both bicycles travel at the same speed. If one rider causes one of the bicycles to move faster, the acceleration and speed of the first bicycle will be transferred to the second bicycle due to the rigid connection. For all intents and purposes, when joined, the two bicycles act as a single vehicle. The connection between the bicycles can be easily disassembled so that each bicycle can be used separately.

Abstract: An apparatus for hitching two bicycles together including a first hitch which connects the apparatus to one of the bicycles and a second hitch which connects the apparatus to the second bicycle. The second hitch includes a stem which is slid through and secured to the head tube of the second bicycle after the front fork and wheel have been removed from the second bicycle.

Abstract: A dual seat adaptor for a bicycle that allows a second person to ride on a conventional bicycle. Both a front seat post and a rear seat post are telescopically received in the respective front and rear seat post sleeves that are the most important structure of the dual seat adaptor. The front seat post sleeve is telescopically received in the top end of the seat supporting tube of the conventional bicycle.
