Crazy machines, creative costumes, adrenaline on the water, and a generous dose of summer energy. On Saturday, 21st June, Prague will host the Red Bull Kolo Molo for the first time, or as it is known in the Netherlands: Red Bull Stalen Ros. The event will turn the Vltava River into a bicycle arena where everything is on the line – speed, style, and a steady hand on the handlebars, as any mistake means a dunk in the water. Prepare for a show that the Czech capital has never experienced before!
Red Bull is renowned for its extravagant events. Just last year, the Red Bull Show Run delighted thousands of motorsport fans in Prague, and the year before, it was a spectacular soapbox race that attracted numerous spectators.
Red Bull Kolo Molo is based on the successful Dutch concept, which took place for the first time in The Hague in 2023 under the name Red Bull Stalen Ros (Steel Horse). Two-person teams design and build their own tandem bicycles, similar to soapbox races, and attempt to navigate the narrow, trap-filled course stretched over the Vltava River. The goal is clear – reach the end of the course, ring the bell, and, if possible, avoid landing in the water.
But beware! The best team is not just the fastest. The jury will also assess the original design of the bike and the showmanship! So participants must not only prove their skills on the saddle but also incorporate creative costumes, choreography, or any other element that transforms their ride into an unforgettable spectacle. The sky’s the limit for creativity!
How Can You Participate in Red Bull Kolo Molo?
Simply form a two-person team, with both members aged 18 or older, and register by 27th April 2025 at redbull.cz/kolomolo. Part of the registration process includes submitting a sketch of the tandem bicycle prototype designed by the team. The jury will then select about 40 of the most creative proposals, who will have the chance to bring their designs to life and present their show to an enthusiastic audience on race day.
Participants will be judged by several figures, including Olympic kayaker Vavřinec Hradilek, who will be on the jury. “The winning team needs to have not only great technique but, above all, energy and a show that entertains both the audience and the jury. The key is to come up with original ideas that everyone will remember,” says Vavřinec, adding, “I look forward to seeing not only a great ride but also the humour and creativity that belong to such events.”

The preparations for the event also involved well-known names from the Czech bike scene – Tomáš Slavík and Michal Maroši. As experienced riders, they would advise participants: “Above all, keep your balance and don’t kid yourself. The collaboration between the riders will be important because a tandem bike is a different level than you think,” says Tomáš Slavík. “And I also recommend taking a deep breath – but not underwater,” adds Michal Maroši with a smile.
Whether as a participant or a spectator – don’t miss this unique event that will bring a huge dose of adrenaline and laughter to Prague’s city centre. For more information, visit RedBull.cz/kolomolo.
