The aquatic sliding vehicle propelled by a pedal gear drives a set of wheels (A,B,C). These wheels are fixed on axles guided by bearings. Interchangeable cages fixed on the wheel axle are provided with paddles (C3) which are submerged in the water to generate the propulsion. The wheel axle has its rotational movement improved by an accelerator (V1) controlled by the cam driven by the pedal gear.
