A wiggling freewheeled vehicle comprises a folding assembly disposed between a main frame and two carrying frames. The folding assembly includes a pivot movably disposed on the main frame, clasp members integrally formed on the carrying frames, and a fastener able to fix the clasp members. Wherein, the clasp members are pivotally engaged with each other at a place where the pivot could fitly penetrate. By wrapping the main frame in the clasp members that are fixed by the fastener, the vehicle is available for a smooth operation. Oppositely, by releasing the main frame from the clasp members, the vehicle could be folded or collapsed while bending the main frame. Moreover, the collapsed vehicle allows the main frame to be arranged tightly abreast the carrying frames for achieving a compact structure. Thus, the collapsed freewheeled vehicle contributes to a reduced dimension and is beneficial for transportation and storage.
