Product description of Knog Oi Classic Large Bike Bell

Description summary

Reinvent your ride’s sound and style with the KNOG Oi Classic Bike Bell. Shattering the mold of ugly, clunky bells, its unique, low-profile shape appears to hover around your handlebars for a discreet yet remarkable look. Instead of a harsh ding, it rings with a beautiful, multi-toned chord—like an angel playing a glockenspiel—that is both pleasant and safely heard. The clever mount includes an integrated cable management system for a clean setup. This Large Oi fits 23.8 to 31.8mm bars, ideal for drop bar road bikes and some cruisers

Bike Bells Generally Look & Sound A Bit Ugly. But Why? What If They Looked Sexy & Sounded Like An Angel Playing A Glockenspiel? A Bell With A Beautiful Tone, But Also A Remarkable Style And Choice Of Materials That Embodies A Rider?s Personality. The Large Oi Fits 23.8 To 31.8mm Bars E.G. Drop Bar Road Bikes And Some Cruiser / Commuters. Please Make Sure You Know Where On Your Handlebar You Are Going To Place The Bell (grips Or Stem) Before You Order As You May Need A Different Sized Bell.

The Look:
- Where Bells Usually Protrude Up Or Out, Oi doesn’t. It Appears To Hover Around The Handle Bars. In One Sense, Its Discreet. But In Another, It Stands Out As Unrecognisable.

The Sound:
- We Tested Numerous Prototypes To Get The Perfect Pitch, Length Of Ring, And Volume. With A Spring-Loaded Actuator Built Into The Mount, The Strike Of The Bell Is Firm And Fast, Allowing A Good Balance Of Volume And Longevity Of Sound. Our Bell Actually Has Several Pitch Tones - One Core And Several Supportive Higher Tones To Ensure Its Unmistakable And Safely Heard. To Compare It To A Musical Instrument, Where Some Bells Play A Single Note, Oi Plays A Chord. Hear It Here For Yourself...

The Mount:
- What About The Handle-Bar Cables? No Worries. Built Into The Shape Of The Mount Is A Cable Management System. So Not Only Does It Allow The Bell To Look And Sound Uninterrupted, It Also Helps Gather Your Cables (for The Organiser Inside Us All). What About Getting It On The Bar. Again, Not A Thing. Just Pop It Over, Give The Hex Screw A Quick Tighten Up, And Youre Good To Go. No Sliding Down The Handlebars, No Dismantling And Re-Assembling.

The Spacer:
- For Handlebars Measuring 23.8 - 26mm In Diameter We Have Supplied A Spacer To Help The Oi Fit Snuggly And Securely To Your Bars. This Can Be Found Discretely Tucked Into The Reverse Of The Grey Packaging Insert.

Features:

- The Oi Bells Shape Originates From Its Home - The Handle Bar. Our Design Team Explored Hundreds Of Iterations In Designing The Style. Then Tested And Prototyped Different Widths, Depths, Materials, Curvature, Actuators, Springs And More To Get To The Optimum Design.

I have these in all sorts of colors on my bikes; they have a bright sound and can be easily mounted along the brake lines on the tops of drop handlebars. They're available in two sizes depending on the handlebar thickness (large for road bikes, smaller for mountain bikes). They're rather difficult to mount on oval, tapered carbon handlebars.

Beautiful and elegant but needs more decibels

Georges

For me, the item is perfect: discreet, aesthetically pleasing doorbell, nice clear sound (lasts a few seconds). I recommend it, but be careful: following various comments mentioning the loss of the spring, I put a dot of strong glue, like Loctite, on the 2 ends of the spring. No problem since installing it 1 month ago.

The bell is of great quality and looks really good. It's quite small and on a black handlebar it's hardly noticeable. The sound it makes isn't the loudest but it's enough to draw the attention. Highly recommended to everyone who needs a discreet bell.

Great bell

I purchased large version, but it is still too small for my road bike handlebars. The screw is holding the bell on the very end of it, hopefully if will not fell apart when I will ring.

On a road bike. Ritchey-Chrétien carbon handlebar, 32mm. slightly oval. Near the power, mumble more cylindrical. It adapts very well to the handlebar. And with its 2 holes for the passage of cables. Good sound. No galling even on bumpy roads.

I love the sound of this bell. It was quick and easy to install

Great bell, but a little quiet

2021/10/19

I frequently ride my road bike on multiuse paths. I've been shouting "on your left!" for a few years, and it tends to 1) scare most people, 2) anger some people, and 3) make folks move to the left, instead of making space on the left. I realized that I needed a bell. I wanted something small, basic, and with a sound that would let people know I was coming without making them jump out of their shoes. This bell does that almost perfectly. The things I like are: + Pleasant tone. Has a nice, friendly "ding" that doesn't scare people. + Control. I can control the volume (to some degree) and the number of dings by how hard / frequently I flick the hammer. + Cable channels. Fits on the limited real estate on my bars. + Small and discreet. Blends in with my black handlebars. Things I don't like: - Too quiet. This bell isn't loud enough at a distance (e.g. approaching fast from a distance, or around a blind corner), when there is environmental noise (e.g. wind, traffic), or when runners are wearing headphones. When I flick the hammer as hard as I can, it's still pretty quiet. - Have to move my hands. I really wish there was a way to mount the bell so I could use it when my hands are on the hoods. The only practical place to put it is near the stem, though, so I usually have to change my hand position to use the bell. Sometimes this doesn't feel safe. My experience has been great overall, and I definitely recommend this bell, but it still needs a little improvement. If they made a louder version (especially with a brass bell instead of aluminum) I'd buy it to replace this one.

Perfect bell.

Super satisfied. It looks super discreet and beautiful on the bike. Excellent quality material like anything from the brand. Beautiful finish and loudness, enough to efficiently alert pedestrians. Very easy to operate and with comfort.

To advice. Discreet on the hanger and strong ringtone to install

Elegant design

2019/05/12

Alessio

Elegant design, I mounted it on my racing bike, it is also functional due to the fact that there is space for cable passages, which if they touched the metal part would prevent the sound. The sound is clean though, maybe it will be for mine, but at the beginning of the ring I hear a slight "splitting" of sound ... I mounted it correctly and without tightening too much as instructed.

Perfect to be heard on the road, Small, beautiful and ... it works. The only downside is that the diameter of the clamp is tailored to the thickest part of the handlebar, (it must be placed next to the stem), otherwise perfect.

Sat on the wheel of a cyclocross perfectly! I hope it will not interfere with the brake understudies. When stretching, at the time of putting the bell on the steering wheel, I was a little afraid that it would not break. But everything worked out and the call sat as it should. The sound is loud and lingering. Class! Top notch packaging! I recommend the manufacturer and I will definitely buy the same for other bikes.

Good looking and handy

2020/06/12

Christophe

First of all it's food looking, but it is also handy. Don't need to watch the bell for using it, just give it a smash with your hand and there is a loud sound produced from the bell. Also a very thin connection with the steering handlebar so you don't lose much space on the bar (good for trekking)

Not to be ashamed of having the doorbell

2023/04/28

Dario

Undoubtedly 15 euros for a bell may seem excessive, but it is the price to pay if you want to have a product well studied in all its details in order to produce a clearly audible sound and at the same time to be placed on the handlebar of the bike with discretion and style. The set of accessories included (shims, Allen) and the packaging are excellent. Advice: for an ideal location, the brake and gear cables must pass under the handlebar so that, by fitting into the space provided in the bell collar, they allow them to be placed in the most ergonomic position.

Perfect !
