A toy vehicle generally comprises a chassis, front and rear wheels supporting the chassis, and a flywheel configured to rotate within the front wheel to provide a gyroscopic effect. An engagement mechanism housed within and operatively coupled to the front wheel is configured to rotate the flywheel in a first direction when driven by the front wheel in the first direction. The engagement mechanism is also configured to allow the flywheel to continue to rotate in the first direction independently of the front wheel when the front wheel decelerates.
