Stand out.

The Knog Oi Bike Bell has garnered a pretty big buzz as of late, and it's easy to see why. With a standout design that tucks stealthily close to your bars, the Oi is a unique way to add some noise potential to your bike. Knog claims this bell sounds "like an angel playing a glockenspiel", and while we can't confirm any heavenly associations, we can say that this bell projects a bright, crisp, ear-pleasing sound while hovering cleanly around your handlebars.

The small size Oi is compatible with 22.2mm bars, while the large Oi fits bars ranging from 23.8 up to 31.8mm in diameter.

  • A unique bell with clean, minimalist styling
  • Size options to fit bars ranging from 22.2 up to 31.8mm

Copper in Small

    I saw this on my friends bike and thought it was so unique that I liked it but she purchased it on vacation. So when I saw think here I quickly bought it in Copper. The tone is nice and pleasant but still attention grabbing. It is not loud like other bike alarms, which is what I liked about it. Overall great product! And I hope Backcountry continues to sell these!

    The sound of silence

    • Familiarity: I've put it through the wringer

    Got this during the kickstarter campaign. Think of it as a beautiful piece of sculpture or jewelry for your bike. It does not make any noise. It certainly cannot warn pedestrians or cars of your imminent approach. My dogs didn't even react to it. Unless your bike is demanding that you put a ring on it, pass on this.

    The bell is too quite

      The bell looks cool, but it is not loud enough to warn people you are approaching.

      Don't waste your $ or time...

      might work for a bike path but durability is zero. i put on multiple bikes and they have all falling apart.

      Very Light but Pointless

      • Familiarity: I've put it through the wringer

      I bought one of these bells for each of my bikes during the Kickstarter campaign. They are terrible. You have to get the thumb-flick perfectly executed in a perpendicular line away from the bell. If you don't, you get a muffled ding and might even twist the spring-loaded lever. Then you'll need to straighten it out to ring again and that means pulling over to do so without risk. If you do manage that perfect thumb-flick, you'll get a very nice-sounding ring that is audible to about 4 feet away. Good luck warning anyone with that.

      Worst bell ever!

      • Familiarity: I've used it several times

      I did the Kickstarter for this bell. It's an "amazing looking" bell. But in use, it's terrible. You can barely hear it yourself on your own bike. No one is going to hear this bell when you ring it. I tried it numerous times on the trails. It's pure junk. I guarantee you will be disappointed. DO NOT BUY!

      Minimalist, not the loudest

      • Familiarity: I've used it several times

      A really sleek product that fits nicely on the handlebars. Its nice for me since I'm just looking for something pretty basic, but definitely isnt the loudest bell out there.

      Still Looks Cool

      • Familiarity: I've put it through the wringer

      Not as loud as I was hoping but it looks great on my bars. It for sure does the job but if you're looking for the loudest bell on the market I would have to tell you to take a pass on this bad boy.


      • Familiarity: I've used it several times

      Bought 2 and neither of them work, all they do is a muffled very quiet and dull ping that nobody can hear.

      Do you hear me coming?

        I love this sleek little bell! It is so loud and I love he minimalist design on the handlebar. Just be sure to get the right size. A large is needed for a lot of standard mountain bike handlebars

        All the other reviews say it's very quiet. Yet your review states the opposite. Is the you work for Backcountry?

        This really makes me question the accuracy of any employee review. Are the just padding the scores for products they need to sell? Won't be the first online retailer to do so.

        Unanswered Question

        Are there plans to carry the large bell to fit 31.8mm bars?

        Too Quiet

        • Familiarity: I've used it several times

        From an aesthetic design viewpoint this is a neat little gizmo. It looks cool and takes up little room on the bar. It is, however, fairly quiet and is therefore not that useful for my purposes. I replaced it with a 'spurcycle bell' and was much happier.
