Mounted it on my gravel bike for weekend rides. Coming down fast hills, I can warn hikers early and they step aside without surprises.

I use the horn around the park path. Kids, joggers, and dog walkers all hear me well, so I’m not yelling or ringing a tiny bell.

My daughter just started cycling to college. I added this horn and she feels much more confident in busy traffic and at crowded crossings.
