FIELD: transport.

SUBSTANCE: water bike includes floating hull, underwater wings, pedals and rudder. Bike hull is made in the form of set of three hulls fixed in centreline plane on common transversal horizontal axis. On the decks of hulls, longitudinal guides are fixed in which longitudinal arms are located with possibility of their longitudinal displacement. On the rear end of arms, vertical struts with underwater wings mounted on lower ends of struts are fixed. The wings are pivotally mounted on the struts so that the wings are capable to turn relative to transversal vertical axis. Struts of each hull are interconnected, and struts of outermost hulls are additionally connected by traverse beams on which two pedals are fixed. On the axis of hulls, flat-topped bracket is fixed. On the rudder, manual drive mechanism is installed to bring all longitudinal arms and longitudinal beam to reciprocate.
