A four-wheel drive toy including a chassis, front wheels operably connected with the chassis, and rear wheels operably connected with the chassis. A flywheel is operably connected to the front wheels and the rear wheels and operable to drive the toy. A front wheel axle is operably connected to the chassis so as to vertically pivot relative to the chassis such that when driving over an uneven surface the front wheels and the rear wheels all contact the uneven surface, thereby ensuring that a driving force from the front wheels and the rear wheels is transmitted to the uneven surface and that the toy runs over the uneven surface.
