Ring and become a safety contributor!

Each time you ring Mosa Bell, it will anonymously upload the location and timestamp to our encrypted cloud-based map, where every Mosa Bell user can discover which dangerous areas to avoid. Our AI separates individual events from location-based patterns. This allows us to push local authorities to work on safety solutions for bikers.
