<p>This bicycle consists of a low, flat frame with pedals at the front and a horizontally adjustable seat, with a back support, at the rear. The distance between the seat and the pedals is measured to neutralize leg weight thereby making travel less tiring. The low seat allows the feet to reach the ground more easily to increase safety. A two wheeled load carrier can be fixed to the back so that the three rear wheels are in line allowing all three wheels to share the load. This also allows the bicycle to be ridden by people who cannot ride a conventional bicycle.</p> |
