RECUMBENT BICYCLE
BACKGROUND OF INVENTION
1. Field of invention The present invention relates to recumbent bicycles, and in particular, front wheel drive, rear wheel steering, and hand and foot power.
2. Related art The bicycle has 3 long evolutionary history, from the first Draisian of 1818, the velocipede of 1855, the 1$74 "ordinary" penny farthing type to the 18b6 safety upright rear wheel drive, front wheel steering bicycle, and culminating in the latest recumbent bicycle.
The penny farthing design was unsafe, the safety upright bicycle, with its saddle seat and large frontal area was uncomfortable and inefficient, the latest recumbent bicyle is expensive, heavy, complicated and of limited utility. By embodying the front wheel drive and general layout of the penny farthing type bicycle, the technological innovations of the rear wheel drive, front wheel steering safety bicyle and the concept of the recumbent bicyle, the present invention, using an innovative frame, remote rear wheel steering, efficient drive layout and imaginitive concept, represent another stage of evolution, which offers greater safety, comfort, efficiency and utility than any of its ancestors, to which it owes its genesis.
