Abstract: A human-powered vehicle related to bicycles and rowing machines consisting of three or more wheels attached to a horizontal frame. For the purpose of a better understanding we will use a three-wheeled vehicle. There is no substantial difference between the front part of this invention and the front part of a regular bicycle. The rear wheels are attached to the frame and are driven by chains attached to their one-way sprocket freewheels. The chains are directly attached to a bar on which the pedals are mounted. There is a sliding board located on the front part of the framework which moves freely forwards and backwards on the frame. The board is covered with a soft foam-type material. The operator of this vehicle lies horizontally on the vehicle facing the ground and places the sliding board under his stomach while holding the handlebars and inserting his feet into the pedals. When the operator pushes on the handlebars his body slides backwards with the sliding board.
