34-year-old brothers Dmitry and Timophey Ryabikiny from the Russian city of Yeisk have created Aqua Star – an original underwater motorcycle with technical characteristics excelling foreign analogues. The underwater motorcycle allows going underwater without any special equipment: the body of a motorcycle rider stays in water and the head – in a kind of helmet serving as a diving-bell and is equipped with an air supplying system. The electronic motors of the motorcycle let it move in all directions underwater. Compared to some foreign analogues, such as, for instance, Breathing Observation Bubble/Scuba Scuta, the developers of the Russian Aqua Star used even glass for the helmet instead of spherical glass that distorts the diver’s visibility and makes the eyes get tired. The helmet of Aqua Star motorcycle also has an airflow system to prevent the glass steam up.
