Abstract
Abstract A toy vehicle utilizes a depressible stunt wheel to elevate the vehicle to perform various tricks. An adjustable nob on the vehicle's chassis permits a user to preselect the distance the vehicle travels before the stunt wheel is automatically depressed. A shaft positionable in various slots in the vehicle's roof permits a user to preselect and fix the angle of the stunt wheel, during depression, relative to the traveling wheel of the vehicle, and the extent to which the stunt wheel is depressed below the chassis.
