UCI Approves Visma-Lease a Bike’s ‘Transformational’ Breathing Sensors ahead of Tour de France

June 12, 2025

Visma-Lease a Bike got the green light to use its “transformational” breathing sensors in competition ahead of the 2025 Tour de France in what could mark a step-change in performance technology.

Tymewear – the brand behind the VitalPro breath sensor – exclusively shared a note sent to Visma-Lease a Bike by the UCI confirming full approval of its potentially game-changing tech.

“Considering that the sensor appears to be commercially available and the data it captures does not appear to undermine the fairness or integrity of the sport, the UCI has decided to permit the use of the sensor in competition.”

Breathing – or “ventilation” – sensors will provide the team of Jonas Vingegaard and Wout van Aert a powerful new metric for training and racing. The tool unlocks a deeper level of understanding of physiological suffering than power or heart rate data. Velo
