The verdict

Pick the Spurcycle Bell if you ride busy city streets and want a 3-dB-louder ring (3x the perceived volume) that other riders and drivers actually hear - it's the loudest premium bell on the market and lasts forever. Pick the Knog Oi Brass if you want a bell that disappears on the handlebar - the flush ring design has zero visual footprint and saves you about $34.

Best value

Knog Oi Brass - 76% of the loudness for 57% of the price, and it doesn't clutter the cockpit.

Best performance

Spurcycle Bell - 3 dB louder, USA-made build quality, and the strike sustains 3x longer than any competitor.
