Bell or horn

Legally required in many cities. A clean 'ping' alerts pedestrians, dogs, and earbuds-wearing walkers far better than yelling.

A real brass bell carries 50+ feet and has a distinctive pitch every pedestrian recognizes. Cheap plastic bells sound like a toy and get ignored. The Spurcycle is the cult favorite — a single ping rings for 4+ seconds — but any solid brass bell will do.

Mount it where your thumb can reach without taking your hand off the bar. On flat bars with grips and shifters, this is the only real-estate puzzle on the bike — measure first.

Picks with a "Check today's price" button are affiliate links to the brand's store or Amazon.

Pro tips from the e-bike pros

Double-ping for pedestrians at distance, single-ping for last-second alerts.
Don't use the bell as a horn — use it as a polite 'I'm here.' For traffic, your voice carries further.
On crowded paths, slow down before you ring. The bell is not a license to keep your speed up.
An electric horn is for traffic, not shared paths: it's far too loud for pedestrians.
