Bee Trail.nl Your safety is our top priority, especially during those solo runs in the early morning or late evening. That's why we offer a powerful emergency alarm, specially designed to give you an extra layer of protection. A simple pull of the cord activates a 120 dB alarm, powerful enough to warn passersby and deter potential attackers. This alarm can be heard from over 180 meters away and is as loud as an ambulance siren.
