A hub and wheel assembly enabling the moving direction of wheels of a vehicle to be adjusted instantly as the exerted pushing force changes direction comprises a wheel mount having wheels mounted thereon, and a swivel base assembly mounted on stroller leg. Wheel mount may quickly assemble with and detach from swivel base assembly. A protrusion of wheel mount, inserted into swivel base assembly, includes a circumferential groove having a cavity provided therein such that a spring-biased locking member may releasably engage with cavity for setting movement of wheels in a linear direction. Further, as a deflecting force is applied on the stroller locking member disengages with cavity for allowing wheels to move to left or right. Once the force is released, locking member will instantly return to its normal position to engage with cavity.
