A rotor with variable hydrodynamic resistance for a stationary water bicycle comprises a central body (12) provided on its perimeter with a plurality of blades (13) of the marine type comprising an inlet edge (13'), an outlet edge (13'') and a convex helical surface, as well as provided on opposite outer faces with axles (14) per pedals (15), wherein each blade (13), at the outlet edge (13''), is connected to the rotor (10) with elastic fixing means (20) adapted to allow the automatic orientation of the blade (13) as a function of the rotation speed imparted to the rotor (10) through the pedals (15), wherein the central body (12) houses means for adjusting the maximum possible opening (30) comprising a mechanical end stop element (31) movable for modifying the maximum possible opening of each blade (13), such means for adjusting the maximum possible opening (30) of the blades being able to be actuated by control means (40) connected at one end to the means for adjusting the maximum possible opening (30). A stationary water bicycle comprising the rotor with variable hydrodynamic resistance is also object of the invention. |
