Austrian mountain biker Elias Schwarzler became the first person to ride a mountain bike across the top of a hot-air balloon.

The stunt represents a significant leap in extreme sports, combining high-altitude aviation with technical cycling maneuvers that had never been attempted together.

Schwarzler, 30, reached an altitude of approximately 950 meters [1], or roughly 3,280 feet [2], above the ground in Austria. The event was the culmination of two years of preparation [1].

During the stunt, Schwarzler navigated his bike across the surface of the balloon's envelope. He then launched himself from the top, performing two front flips [3] during his descent. After the aerial maneuvers, he deployed a parachute to return safely to the earth.

The athlete sought to establish a world-first record by integrating these specific disciplines [2]. The operation required precise coordination between the balloon pilot and the cyclist to maintain stability at the peak altitude.

While the exact date of the flight was not specified, the stunt was completed in early 2024 [1]. The achievement has been documented via video, showing the cyclist balancing on the fabric of the balloon before the final jump [3].

This stunt pushes the boundaries of extreme sports by merging aviation and freestyle mountain biking. By successfully executing a high-altitude jump from a non-rigid structure like a hot-air balloon, Schwarzler has set a new precedent for technical risk and preparation in the pursuit of world-first records.
