Knog Oi Bike Bell

$21.99 on Amazon

Most bicycle bells look like clunky metal mushrooms bolted to your cockpit. This CNC-machined aluminum ring hugs the handlebar so closely it barely looks like a bell at all, even leaving built-in channels to route your cables cleanly underneath. The striker produces a crisp, dual-tone chime that cuts right through traffic without sounding obnoxious.
