An adjustable jumping apparatus having a hollow housing with handlebars for a rider to hold and reinforced foot pegs for a rider to stand upon. A pole extends downwardly from the housing, has a ground-engaging base, and slides in and out of the housing through a sleeve integral with the lower end of the housing. The device is propelled by at least one bungee cord attached at its upper end to a disc integral with the upper end of the pole and at its lower end to the interior surface of the lower end of the housing. The device is adapted for easy installation and removal of bungee cords for adjusting the amount of rebound force available to the user.
