This is my favorite part of the description: “Moreover, modulation is key: from a light courtesy “ding” while passing another rider to an alarming “DING-DING-DING” to grab a driver’s attention.”
As a note I didn’t have bells for my bikes so I funded the project. I think I’ll wait to determine how loud they are until I have them in person. But the sound in the example was so clear and crisp that I think it will cut through a lot of background noise on the trail. I also liked it because :ahem: it was a pretty sound. Maybe it won’t annoy people as much as some other bells/ methods I’ve heard. We’ll see!
