Abstract
An unmotorized sand-rideable bicycle utilizes oversized balloon tires that have an enlarged footprint to permit the bicycle to ride up over even loose sand to provide ease of pedaling, as well as enhanced steering and stability over that associated with standard bicycles. A positive traction gear assembly may be employed to switch between single and dual rear wheel drive.
