Oi Prima Bell

Nice loud ring and easy to install , gets walkers attention

Better than the previous version

I like how the new hammer works. The previous hammer could get misaligned and had to be readjusted, but this one is much more robust and looks like it can't move.

Bigger sound

Has a few more decibels than the older one. But then there are times when I wish I had a fog horn on my bike!!

Knog Oi Prima

Easy to install and works perfectly.

The volume of the Oi Prima Bike Bell (large) is weak, and the tone is surprisingly dull — more of a “thunk” than a clear bell tone.

1 2 3

"RE-ENGINEERED DESIGN FOR PERFORMANCE AND LONGEVITY"

Subtle, until you strike it.

Every feature is fine-tuned for clarity, durability, and effortless installation.

WAVETEK

The innovative Oi Prima WAVETEK hammer delivers a louder, longer-lasting, and more consistent chime. The subtle wavelike motion creates a crisper, clearer tone that rings at 80+ decibels.

REFINED AESTHETIC

Every detail is meticulously considered. From tapered edges - inspired by the aerodynamic intake of a jet engine - to the minimalist silhouette and intricate laser etching.

ROBUST BUILD

The hinged clamp system makes installation quicker, easier, and secure whilst the bell's spring remains hidden within and can’t be overextended for a cleaner look that is engineered for lasting strength.

BEAUTIFUL SOUND

Loud enough to cut through traffic and trail noise, but tuned to be pleasant. The improved hammer and striking surface work together to produce a crisp, clean and considerate sound.

‘It's very loud. It's very good-looking.’
