Born in Špindlerův Mlýn, Kuba grew up surrounded by winter sports. He first stepped onto a snowboard at the age of two, although he initially focused on skiing. A silver medal at the Czech Championships proved to be the turning point that led him to dedicate himself fully to snowboarding.
Since then, he has collected success both at home and abroad, including gold in slopestyle and silver in Big Air at the European Youth Olympic Festival. In 2024, he made snowboarding history by becoming the first person in the world to land a switch boardslide triple underflip off a rail. His 2024/25 season has been his strongest yet, with fifth place at the Big Air World Cup in Chur, a historic fourth place in Klagenfurt, the best result ever achieved by a Czech rider, and ninth place in slopestyle in Laax.
Beyond competition, he is known for his creative video projects, including riding uphill through a snowpark using a ski lift. When he is not on the snow, he studies Business Administration at the University of New York in Prague and plays golf, which he sees as a form of mental training.
