Hand and Foot Tricycle - Sports and Recreation Bike
I am a Korean inventor. I have made several hand & foot bikes which have a unique automatic steering system. It would be ideal for transportation, traveling, physical exercise, assistance for the handicapped, the aged, and women who cannot ride a traditional cycle.
The user makes a pair of front wheels change directions by shifting the center of weight and moves forward by rotating the rear wheel, thus making it easy to ride on a uphill road.
The hand and foot recumbent trike can be also converted into a manual tricycle designed to be driven with both hands and both feet.
