Foot/hand-operated fast fitness bicycle and foot/hand-operated fast fitness tricycle

Abstract

The invention provides a foot/hand-operated fast fitness bicycle or a foot/hand-operated fast fitness tricycle, which achieve the purpose of riding with a fast fitness effect. Pedals, a pedal driving gear and a pedal driving chain are arranged between the lower end of a rotating shaft that is arranged inside a vertical fixed bearing at the front end of a frame and a rotating shaft of a front wheel; a group of driving gear and driving chain and a hand-rotated gear are arranged in front of a rear wheel and below and in front of a seat, and the hand-rotated gear is connected with the driving gear through the driving chain; and alternatively, a group of driving gear and driving chain and a hand-push/pull gear bar are arranged in front of the rear wheel and below and in front of the seat, and the hand-push/pull gear bar is engaged with the driving gear. A rider drives the pedals with both feet to apply a forward push force to the front wheel and simultaneously rotates the hand-rotated gear by hands or pushes and pulls the hand-push/pull gear bar by hands to apply a forward push force to the rear wheel. The foot/hand-operated fast fitness bicycle and the foot/hand-operated fast fitness tricycle have the advantage of quick speed of a motor vehicle and also have the advantages of the common bicycle and the common tricycle, such as simple structure, no energy consumption, no air pollution and whole body building effect. The foot/hand-operated fast fitness bicycle or the foot/hand-operated fast fitness tricycle are very suitable for being used as urban transportation means.
