Customer Reviews
Discreet and stylish but the Luxe bell emits a stronger and nicer sound.
I’ve never been comfortable with traditional bike bells—too big, bulky, sounding weak. The Oi Prima from Knog (Canadian-Australian Commonwealth brothers and sisters) offer an incredible opportunity to upgrade my cycling kit without having to wallow in the depression caused by purchasing gear from fascist, racist, totalitarian junk-lords from the usa. Knog has it right—this bell, their bar-mounted lights (I now use the 1300 Blinder), and their helmet-mount lights (I also now use their Blinder X 2300 helmet kit)—ALL of these upgrades have thoroughly met my expectations! Commonwealth brothers and sisters: amazing products, incredible ingenuity, R&D, and providing tech which cyclists require (both on trail and urban) for staying safe! Canada, Australia, New Zealand, and the EU—ALL BROTHERS AND SISTERS partnership—ANTI FASCIST!
Love this bell. The tone is sharp and volume is loud, but not obnoxious. The form factor is small and stays out of the way on my race gravel bike, keeping the bell out of sight and out of mind until I need it. A bit pricey, but feels premium and robust. Doesn’t make a peep on chunky gravel / singletrack until I intentionally ping it with my thumb. Honestly perfect.
Well built and the right sound for hikers and other bikers to hear on the trail! Good looking piece!
Great bell, very sleek and low profile.
