A mobile toy of the type designed to move over a surface or through the air and comprising an energy storing rotary element in the form of a flywheel which, when set into rotational motion, provides energy to propelling means thereby causing movement of the toy. The flywheel includes a hub with a centrally located channel designed to movably engage a driving means in the form of an elongated drive shaft having a convoluted outer surface. Linear movement of the shaft within the channel relative to the flywheel causes rotation of the flywheel due to the correspondingly shaped convoluted configurations of the exterior surface of the shaft at the surface of the channel.
