A good bell should be easy to use, easy to hear and never get in the way. The Knog Oi Prima does exactly that, combining a clean, low-profile design with a clear, confident ring that cuts through traffic, shared paths and busy streets.

Unlike traditional bells that sit on top of your bars, the Oi Prima wraps neatly around them for a sleek, integrated look that won’t clutter your cockpit. The sound is bright and attention-grabbing without being harsh, giving pedestrians and other riders a clear heads-up without startling them. It’s simple, effective and always within easy reach when you need it.
