‘Underwater Bicycle’ Device Propels Swimmers and Divers Forward at Superhuman Speed
French company Seabike has developed a device that acts as an underwater bicycle, helping swimmers and divers move underwater at impressively fast speeds. The device, which bears the same name as the company who designed it, is made to be strapped to the waist of swimmers, who are then pushed through the water by pedaling the propeller device located at the end of the machine.
