I charge it once a week and it easily lasts all my city rides. One press is enough to cut through traffic noise every time.

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

We ride as a family on narrow lanes. This horn lets us alert drivers from far away, so they slow down before coming around corners.

I ride early mornings in the dark and this little horn keeps walkers and drivers aware. Alarm mode also lets me leave my bike outside calmly.

I lock my bike outside the train station. The anti-theft alarm went off once and the guy walked away fast while everyone stared at him.
