Spurcycle Original Bell vs Knog Oi Classic Bike Bell
Which should you buy? Our verdict on both, pulled from our full The Best Bike Bells: 4 Compared (and One to Skip) comparison.
The Original wins on the one spec that decides whether a bell is usable, with a stated 22 to 36mm range and both bands supplied, so one bell fits whatever you own. The Oi Classic is the one to take if you want the same certainty for less money and are happy to pick the right size at checkout.
Spurcycle Original Bell
Buy itThe widest published fit range here, 22 to 36mm with both bands in the box, on a brass dome that is the point of the whole thing.
- Spurcycle states a fit of 22 to 36mm, with a Small Band and a Large Band both included.
- Brass alloy dome and an aluminium hammer, with the dome stated at 30mm across by 20.5mm.
- Spurcycle states a weight of 45g, with a lifetime guarantee.
- Made in the USA, in raw brass or a black DLC finish.
- A 2.5mm hex tool is required, and Spurcycle lists only the bell and two bands in the box.
- Most expensive bell here by a wide margin.
- No decibel figure published, so the loudness claim rests on description alone.
Knog Oi Classic Bike Bell
Buy itA bell that wraps around the bar instead of sitting on top of it, sold in two clearly stated size ranges with the shims and the hex key included.
- Two sizes with numbers attached: Small fits 22.2mm bars, Large fits 23.8 to 31.8mm.
- Shims are supplied with the Large size for an exact fit, and a hex key comes in the box.
- The ring-shaped body wraps the bar rather than standing proud, so it clears levers and bags.
- Knog states a considered cable management system, which matters on a cluttered commuter cockpit.
- The two sizes mean you have to know your bar diameter before ordering, with no single bell covering both.
- Knog lists a plastic, spring-loaded hammer rather than a metal striker.
- No decibel figure published.
