The Topeak UTF Bellonside is easy to use, easy to fit without taking up space on the handlebars, and sounds loud and clear.
A good bell is one of those accessories that can be difficult to get right on road bikes – you don’t want something massive on the bar, but constantly having to shout at people to let them know you’re there really perpetuates the angry cyclist meme. The Bellonside is a very good solution: small enough to keep under your computer mount, loud enough to alert and be heard, and straightforward to install.

It’s designed to work with Topeak’s UTF Multi-Mount family – handlebar, integrated cockpit or four-bolt stem versions. I have been using one for the last couple of years, and found that it was a cinch to mount as it uses the GoPro mount, so you just align the arms, stick the bolt through to hold it in place, and adjust another bolt to make sure it sits comfortably to use from the handlebar. The whole process took less than a minute.




The only element I found a little annoying was that when it’s in place you can’t mount anything else underneath it, so I couldn’t run both the bell and a camera, for instance.
The body is a mix of bronze, stainless steel and engineering-grade polymer; it feels robust but still allows for a good loud ring.

I found the tone pleasingly clear and sharp enough to cut through most noises you would come across on a daily commute. While it’s not as loud or rich as some high-end bells, it performs its core function well.
It’s also well priced for the quality. I reviewed Lezyne’s Classic Brass Bell a few years ago, which is £15 but not as loud and nowhere near as convenient.
And it compares well with more expensive options such as the £27.99 Knog Oi Prima. It may not have the Knog’s sleek looks, but it seems like a similar volume and convenience.
Overall, this is a tidy and well-designed bell that delivers on its promise: it’s loud, clear, and compact. It isn’t the fanciest bell out there, and you’ll need a compatible UTF mount to use it, but if you ride regularly and want a no-fuss alert system, it’s a very good choice.
Verdict
Well-made and well-designed bell for UTF Multi-Mount users
