Product description
The premium designer Knog Oi Prima bell is subtle to look at, but unmissable when rung.
The bell combines top-notch aesthetics, quality materials, and innovative WAVETEK technology. The result is a clear, loud, and pleasant tone that reliably alerts those around without unnecessary disturbance. It will be appreciated not only by cyclists who often ride in the city and on bike paths.
Elaborated to the last detail
The Oi Prima is equipped with a robust yet unobtrusive spring mechanism and elegant attachment using a hinge system. The minimalist shape with gently chamfered edges inspired by a jet engine is complemented by detailed laser engraving.
Every element is designed with an emphasis on functionality, appearance, and long service life.
