Described is a wind-up ride on toy with wind-up mechanism to propel a rider. The ride on toy comprises a body portion having a seat portion. A first axle is rotatably connected with the body portion, while a pair of wheels are connected with the first axle. The wind-up mechanism has an elastic band and a rotatable spool. The elastic band is fixed at a first end within the body portion and is attached with the rotatable spool at a second end. Additionally, the rotatable spool is operably connected with the first axle, such that winding the elastic band around the spool causes the elastic band to transition from a relaxed state to a stretched state and, upon allowing the elastic band to return to the relaxed state, the spool rotates the first axle and pair of wheels, thereby causing the wind-up ride on toy to propel forward.

A flying toy includes a chassis, a rotor and an elastic rope. The chassis has a first mass includes a first pair of wings extending therefrom. The rotor is rotatably connected to the chassis. The rotor has a second mass larger than the first mass of the chassis, and the rotor includes a second pair of wings extending therefrom. The elastic rope is positioned in the chassis and configured to pivotably couple the chassis to the rotor. The elastic rope is operative to impart a torque to the rotor.
