ABSTRACT:
The water bicycle has three basic components: an elongated floatation board, a propulsion and seat unit which is releasably connectable to a central portion of the board, and a steering unit which is also releasably connectable to the board, in front of the propulsion and seat unit. These two units are respectively inserted into an opening and a bore provided in the board and are releasably locked therein by snap connectors of the self-binding type. Such locking makes the components quicker and easier to assemble and dissemble.
