What is a Bell / Horn?
The simple warning device you ring to alert people ahead.
Simplified schematic — not to scale.
In plain English
A bell (or occasionally a horn) is a small handlebar-mounted device you use to warn pedestrians and other cyclists of your approach, especially on shared paths.
A simple analogy
“It's the polite equivalent of a car horn — a friendly heads-up rather than a warning blast.”
How it works
A simple lever or thumb-flick strikes a small metal dome, producing a clear ring that carries further than shouting.
Signs of trouble
- ⚠Weak or muffled ring
- ⚠Lever sticking or not returning
- ⚠Loose mount that spins on the bar
