Oi Prima Bike Bell

Para la TREK MADONE que campana Timbre puedo poner ???

Love the look and feel of this bell BUT there is an issue for me.
It is mounted on my drop bar gravel bike so sometimes on chunky trails.
When flicking the hammer with my hand off the bar the result is not always a robust ding.
The hammer fails to strike the chime.
It does work as expected with a more deliberate press but in some scenarios there is just not enough time to do that.
Wondering if there is an adjustment that can be made or perhaps one of the other models would work better for my use case.
Otherwise it is a great looking bell with a substantial tone.

Beautiful design, feels well made and sounds great.

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!

Never been more satisfied with a choice 🙂 Good job, Knog!

I am riding a new trail with a lot of hikers. I needed a compact bell that does not crowd my cockpit and can be actuated when riding downhill around blind corners to warn people. Only complaint is that the hikers have difficulty hearing it when they have ear buds in, so they would like it to be louder.

Super high quality build, very convenient Hannibal strap and allows you to take the light off and use as a single flashlight. Highly recommend

Sound produced by the bell is loud, rings long, and is a pleasant tone. I like the small form factor and quality seems high. The cables route in a funky way, which required me to install it backwards. But it still works fine

Best discreet bell I bought. And definitely caught the attention on many on noise cancelling headphones.

Nice sound
Compact
Fast shipping

I actually purchased 3 of these, they are easy to fit and have a distinctive LOUD ding 🛎️!!

The bell design is really nice.. But I expected a louder more ring sound.
It's actually pretty silent. I Have to ring more often that anyone hears me. Also if the bell slips around the frame, than the sound also changes in a bad way... Its unfortunately not that nice as I thought it would be.... The design still is great..

Like the low profile. Sounds great.

I like the low profile and understated design. Bell could be a bit louder and is even occasionally muted by the striker itself. Mostly avoidable with a little finesse. I can also confirm the striker will unintentionally hit the bell on rough terrain. Overall a very nice bell. Worth it for me for the aesthetics but might not be for you if you want something nice and loud for safety.

This is an absolute amazing bell it rings out really well and looks stealthy in the bike. I love its clean simple look. Very nice product! I a super happy with it!

Absolutely love Knog products! Bell sounds great and the discreet profile on the handlebar is a winner!

Overall, I like the sleek design of the Oi Prima Bike Bell.

However, the sleek design comes with a few engineering/design limitations.

1. The fit for my new bike is extremely tight and couldn't be put exactly where I wanted it. The sizes on the site are exact, there is little room for accommodating a modern non-straight bar.

2. Engineering: There is a cutout for wires, unfortunately it is fixed to a location and can not be moved. So if your wires aren't in that exact location, it doesn't work.

3. Bell: super touchy, doesn't always ring well....especially if it is rubbing up on anything. However, it does work well if struck perfectly.

I would buy it again if the implementation design was a little more flexible

Expensive for what I have. The spacers did not work. I had to dig around my shop for a proper spacer. $40 including shipping. I don’t find good value for what I paid.

not loud enough! I will have to buy one to replace this....

Everything was excellent!

Slim profile and nearly invisible to others, until it rings and the group is trying to figure out who has a bell.

Excellent

It’s possible I got a defective unit. The design is great, functionality and sound not so much.

Very nice finished. It works as intended.

The stealthy design is excellent, however in practice the bell is too quiet as a legitimate warning device and I find it dings constantly when not riding on a perfectly smooth surface.

I have it mounted close to the stem on drop handle bars. It very compact and has a good sound.

If you hate clunky, this is the dinger for you. It's streamlined and great for alerting people on the trail or path that you're coming and need some space. Much better than shouting "on your left" and watching people jump in fright (although less comical). On one bike, I mounted it on the top tube near the handlebars. On another bike, I installed it on the stem.

I bought the large diameter Knog bell to fit my setup. It went on easy, unlike the earlier bell. Best part, it fits, has a nice tone and the color (bk) matches the setup perfectly. All around, I am pleased.

I love these bells but on a mountain bike the bar is narrower where you want the bell so it’s a thumb 👍🏻 flick.
