About Timber
In 2012 we invented the mountain bike bell, with the simple goal of improving communications on multi-use trails and paths. Ten years later, we’re still designing innovative new products at our San Diego, CA headquarters. We keep our products small, durable and effective, so you can enjoy the ride!

Trail awareness when you need it. Silence when you don't.
Timber helps keep trails open to mountain biking
- The motion of the bike activates the sound.
- Because the sound is passive, you communicate to other trail users a friendly, "Hey, I'm just letting you know I'm here". (Instead of "Beep, beep! Get out of my way!)
- The advance notice gives hikers or oncoming riders time to find a safe place to move off the trail.
- The crisp clean sound of the solid brass bell travels a long distance, so you'll announce your presence well in advance.
For more frequent ringing on smooth terrain, mount your bell at a slight diagonal
Standard Mount
If you normally ride a variety of terrain, with rocks, gullies, jumps and downhills.
Diagonal Mount
If you typically ride smooth and gentle trails, or if you would like your bell to ring more often.
Seat Post Mount
If you only use your bell on downhills, and steep technical descents.

I started with the Original Quick Release bell. It was fantastic. Pleasant motion activated cow bell jingle. Ability to set the frequency and easy to mount. Perfect for riding multi use trails and bombing downhills while alerting those around you in the proper way for where you are and what you’re doing. The only issue was the click mechanism for setting the frequency and turning the bell on and off began to loosen up, after a few years and thousands of miles of riding. No big deal, just lost the ability to turn it off when not needed.I just ordered the new and improved Quick Release Model Yew! It fantastic. Many improvements to make it more robust. The housing is stronger. The package contains multiple shims for different size bars or alternate mounting points. The mounting systems is much more robust. The best part is the mode switch has been resigned with replaceable parts and a much firmer click. It is now, what I consider, perfect. Do the right thing. Buy it.

I live in Northern Kentucky and do quite a bit of high speed downhill riding on multi-use trails with lots of hikers/dogs. After having it awhile I find that I like the bell on the seat post the best - in that position it stays pretty quiet when on flat ground or climbing, but then really gives a good warning when going downhill without the need to flick the switch back and forth like u need to do when mounted on handlebars. On the seat post you can “hit it and forget it†and also looks better mounted there, IMO. Also it WILL get smashed against something at some point no matter where u mount it so deff recommend the flexible strap version vs. the fixed, bolt on version. Wish it sounded more like a cowbell and less like a jingle bell, but that is a minor complaint! lol

Love the passive functionality of this bell for mountain biking on trails with high speeds and blind corners. Other trail users will be aware of your presence far sooner than the typical bell you ring yourself which are great on paths but not so much in the woods.

Easy to install and perfect, tight fit. No vibration or sound while riding, until you need it to. High quality

Fits many sizes of handlebars. The shut off feature is nice for when wanting a quiet ride and great when activated to avoid surprising people and animals on blind corners, so I bought 4 of them, one for each bike I ride.

Very unique there’s a lock position and when need to let someone know your coming release and pull down trigger. Has a deep ring( cling cling) does looks like a cow bell just made for the bike.

This allows me to not always be saying “on your left†at some local trails where people love to walk 4 wide and not pay attention to their surroundings.It has a good tone that is t aggressive and can be heard from a decent distance.

Die Klingel funktioniert gut im Gelände, die Passanten und andere Waldbewohner hören diese beriets schon aus ca 30-40 meter Entfernung. Bereits bei der ersten Waldtour haben sich Passanten für die rechtzeitige und dezente Annährung bei mir bedankt!Auf Asphaltierten Wegen schalte ich die Klingel bei Bedarf ein und rüttele leicht mit dem Lenker wenn ich die Klingel auslösen möchte. Das klappt erstaunlich gut.Einziges Manko - das ist aber mein persönliches empfinden- ist dieser Gummi-Laschen-Verschluss. Warum? Wieso keine herkömmliche Imbus schraube? ich will diese "höherpreisige Klingel" nicht im Gelände verlieren und ich möchte auch ungern, dass die Klingel von Dritten einfach mit wenigen Handgriffen und innerhalb von 2 sek. abgenommen werden kann.Ansonsten bin ich happy mit dem produkt.

My bell arrived today, I was eager to fit it and give it a try! I attached the bell to the bike and to be honest, was sure what expect.Wow 😮 to make it work you need to pull the lever, absolute rubbish? I don’t have the time to pull the lever back and forth, total waste of good money.The bell went straight into the bin, the cheap one that came with the bike is much better.
