Bells and Horns
Browse used bells and horns for sale from riders across the UK. The category covers spring-struck ping bells, rotating dome bells, thumb-lever designs, brass and steel bodies, and louder air or electronic horns for traffic, in the standard 22.2mm bar-clamp size and in oversized bands for 31.8mm bars. It suits shared-path and towpath riders who need an audible warning, anyone rebuilding a town bike, and riders after a specific finish to match a build.
Do I need a bell, and what type?
A bell is not a legal requirement on a bike already in use in the UK, though new bikes are generally sold with one, and shared paths and canal towpaths are where it earns its place. The mechanism decides the sound: a hammer-and-spring ping bell gives one clear note that carries, a rotating dome gives a longer trill, and a flick-lever design is the easiest to reach without moving your hand far from the brake. Material matters more than it sounds — brass rings longer and warmer than pressed steel or aluminium, which is why Crane brass bells are chosen for tone rather than looks alone.
When is a horn the better choice than a bell?
Horns are for traffic, not for warning a walker. An air horn or an electronic horn is dramatically louder than any bell and cuts through a car's closed windows and stereo, which is the situation a bell cannot solve. The cost is bulk, a canister or battery to maintain, and a noise that startles people at close range, so most riders who fit one keep a bell as well for path use. If you are riding mainly on quiet lanes, a bell alone is enough.
Will a used bell fit my handlebars?
Check the clamp diameter first. Most bells are made for the 22.2mm section of a flat or riser bar; drop bars are 23.8mm at the hood and 31.8mm in the middle, so a standard bell needs a shim or a dedicated band. Some designs mount to the stem faceplate or a spare accessory band instead, which is worth knowing if your bars are crowded with a light and a computer. Confirm the seller has the correct band and bolt, as these are small and easily mislaid.
What wears out on a used bell?
The spring and the striker are what fail. Give it several rings — a bell that sounds dull or dead usually has a tired spring or a striker that has worn a flat and is no longer hitting the dome cleanly. On rotating bells, check the ratchet still returns rather than free-spinning. Look inside the dome for corrosion, since a bell that has lived through a few British winters can rust at the pivot and stiffen up; brass resists this far better than plated steel. Then check the clamp band for cracks at the bolt lug and confirm the bolt threads are not stripped, which is common where someone has over-tightened a small M4 into aluminium. On horns, test that the button contact works and, for air horns, expect the canister to need replacing regardless of what the seller says.
Is buying a bell used worth it?
For an ordinary plastic-domed bell, rarely — new ones cost very little and arrive with a fresh spring and the right band. Used makes sense for the things you cannot buy cheaply: a solid brass bell, a period-correct bell for a restoration, or a well-made lever design where the retail price is high enough that half of it is a real saving. Judge it on sound and on whether the mounting hardware is complete, not on the finish.
