Abstract: A rapidly detachable switch device for children's vehicles, including a handle assembly that selectively effects switching between plural scooter vehicle configurations, from a fixed-spread sporter configuration to a free-swinging flicker configuration, from the flicker configuration to a fixed scooter configuration, and back from the flicker configuration to the sporter configuration by moving a switch lever member between rearwardly lowered and near-vertically raised positions. The various configurations can be selected rapidly, realizing a three-in-one function for vehicles that can be switched by a rider of the vehicle, the lever being pivotally included in a conveniently removable handle lever assembly.

Abstract: A miniature vehicle includes a chassis frame, front and rear wheel assemblies operatively coupled at front and rear ends of the chassis frame respectively, a motorized assembly supported on the chassis frame to power the rear wheel assembly, and a foot steering arrangement operatively coupled to the front wheel assembly. Therefore, the user is able to control the miniature vehicle by the feet of the user to precisely steer and control the miniature vehicle.
