The simply-named Oi, made by Australian biking gear firm Knog, is a motorcycle bell for individuals who don’t love bike bells. Such of us could also be notably eager on the most recent mannequin, the Oi Prima, because it’s sleeker, slinkier and better-functioning than ever earlier than.
Launched in 2016, the original handlebar-encircling Oi was designed as an alternative choice to conventional dome-like bells that protrude up from the bars. Nonetheless bought because the Oi Traditional, it incorporates a round internal mounting ring with a coil-spring-loaded, thumb-activated striker. The C-shaped metallic resonator is suspended on prime of that ring.
In 2018, Knog upped its sport by introducing the Oi Luxe. Retaining the identical fundamental type because the Traditional, it changed that mannequin’s bobbly coil spring equipment with a stronger lever-hammer striker. Because of this, the bell’s brass “dinger” hits the resonator extra straight and with extra power, producing louder and more true chimes.

Quick-forward to 2025, and behold the brand new Oi Prima. Priced at US$32.99, it occupies a distinct segment above the $21.99 Traditional and beneath the $44.99 Luxe.
Just like the Luxe, it makes use of a lever hammer as a substitute of a coil spring … nevertheless it’s a higher one. The Prima’s new-and-improved hammer is named the Wavetek, and it is significantly lower-sitting, curvier, and easier-to-reach than that of the Luxe.
Moreover, as a result of it does sit decrease, its spring now cannot be overextended and thus prematurely worn out. On a take a look at experience, I additionally observed that as a result of the hammer would not get pulled again as far, the bell is much less liable to slipping across the bar. That mentioned, the Prima nonetheless persistently produces a nice, loud chime, which Knog claims is over 80 decibels – that is 5 db louder than the Luxe. Have a hearken to my demo bell within the following video.

The Prima can also be simpler to mount on the handlebars – just by tightening down a single included hex bolt – as its two fold-in sections are completely hinged collectively. Against this, the two-separate-piece Luxe tends to disintegrate as you are attempting to mount it. I even lately misplaced a part of my Luxe as I used to be using, when it got here aside after the bolt fell out.
So why is the Luxe nonetheless pricier?
Effectively, whereas it is made solely of metallic (not counting its vegan leather-based bar shim), the Prima’s mounting ring and hammer lever are made from glass-filled nylon and TPU (thermoplastic polyurethane). Though completely serviceable, these plastics do make for a less expensive feel and appear.
