  • Patent number: 9561837
    Abstract: The Gear Reduction Tricycle Wheel invention provides two methods of operation of a tricycle with the use of a simple locking pin. When the pin is inserted into the wheel, it operates as a standard wheel would. Without the pin in place, the wheel requires about four times less effort to move with a similar reduction in speed. This gives the option to move with superior control up, down, and over difficult terrain and within limited space (indoor, home, daycare). One can get the sensation of a good ride without the required distance. This new design in the wheel includes gears within the wheel where spokes usually are. In the absence of spokes, side disc plates support the tire rim and the gear axles.
