Knog Oi Classic Bell

Bike bells generally look & sound a bit ugly. But why? What if they looked sexy & sounded like an angel playing a glockenspiel. The bells fit on almost all cylindrical bars. The Large Oi is for all bar sizes up to 31.8mm. The Oi will also work on any aero bar with a 16mm cylindrical section (usually near the stem).


  • Size: Small bell fits bars 22.2mm diameter / Large bell fits bars 23.8mm - 31.8mm (How to measure your handlebars).
  • Weight: Small 18g / Large 28g
  • Material: Aluminium with Nylon mount & acctuator
This was just the right kind of bell I was looking for to fit my new E Bike and easy to fit. It also left me space on my handlebar to fit my front light. Excellent product
Sound is good and decent
Trendy classic bell, great value for your money.
I like this black version, as it's just completely unnoticeable on my Turbo Levo handle bar.
Have a new Cannondale Synapse and the cabling slightly interfered with the bell install but turning it slightly downward works just fine. Truly a unique item. Bought black and on the black handlebars it is almost invisible. Until it rings and that great sound announces my arrival. Though I go a bit slower than I used to go, still want to avoid any collisions. Thanks to Knog for a great product.
So much better than all the cheaper look-a-likes. Loud, and well manufactured.
Very sleek! Looks great and rings loud!
Compact, stylish, high quality
Superb little bell, I have one on all my bikes. Great sound, easy to activate and yet unobtrusive.
Very high quality. Pleasing timbre.
Very low profile and you can`t even really tell its a bell looking at the bike. IMO far superior to standard bells. I`ll be putting them on my road and mtb
A nice bell innovation. The spring on the striker could be stiffer or more durable though as it appears to have bent out of position a little. However the bell still works.
Compact and stylish. Perfect for my roadbike bars.
Well designed and discreet in appearance.
Very well made easy to fit and has a loud sound, just the ticket.
Nice tone!
Nicely made and packaged. Doesn't look as clumsy as an ordinary bell and therefore keeps the handlebar looking tidy! Sounds good too.
OK, it's expensive and not very loud, but it's the koolest bell out there, it's unobtrusive on the bike and it's loud enough to alert peds you're coming through
Really stylish - looks great on my bike, and has a nice tone. I bought this because of the low profile, and it allows me to put my bike on its handlebars without removing the bell :) Also, I ordered the wrong size, and returning for the correct size was pretty easy
Nice product, looks good on the handlebars, easy to fit, and works well. Buy it!
Safety first, danger last. Works well. Little difficult to get position correct. Multiple attempts to perfect. Not really a problem. Happens with all products. Try until it suits you. Looks incognito.
Compact design with distinctive sound. Works and looks good.
Nice bit of kit, stealthy and stylish, and pleasantly loud enough. Spring seems a bit fiddly but time will time.
Neat bell. Nice design.
Gorgeous design, fits and works perfectly. Can`t address durability issues
Love this bell. Looks inconspicuous and not like the cumbersome bells of old
Fast shipping to Australia, no problems at all fantastic bell takes nothing away from the look of your bike.
Really look smart on my handlebars. It has a beautiful and clear ring.. Once fitted it loose a bit of its resonance.
Exactly what I hoped for! A nice unobtrusive bell for my road bike that is more than loud enough for my daily commute.
