Hydrobike is an Human Powered Boat, a recumbent
bike for locomotion in water. It can be used
both in recreation and professional sport.
To ensure an adequate drive and stability of rest
position the hull construction is based on a catamaran-type. Both recumbency position and directfront drive offer an efficient acceleration. Velocity is controlled by a pitch propeller. With its vertical rotation the drive mechanism also substitutes the rudder. Rotor blades and direction can be regulated by bowden cables.
