Overview
- Škoda published research and showed a mechanical prototype built with University of Salford researchers, and it is working with partners to put more units on bikes in London.
- The fully analog design uses two resonators and a hammer that strikes in an irregular pattern to create sounds ANC systems struggle to suppress.
- One resonator targets a narrow weak spot around 750–780 hertz where many ANC algorithms cancel less effectively.
- VR simulations and street tests with Deliveroo couriers in London found pedestrians heard the bell up to 22 meters, or roughly five seconds, sooner than a standard bell.
- The device is not on sale, but Škoda has released its findings for others to use as London reports widespread headphone use and a 24% jump in cyclist‑pedestrian collisions in 2024.
