The Knog Oi Classic is a really innovative bell that is loud enough to grab attention and sleek enough on the handlebar that it suits almost any bike. Having the ability to push back the hammer a little harder would be nice, but it still works well.

The Oi is possibly the least bike-bell-looking bell ever. At first glance, you probably wouldn't know what it was. It just looks like a thin piece of metal wrapped around the bar, a particularly nice piece of brushed finish metal in this copper version I have to say (though I'm not sure it 'embodies' my personality). It feels solid and well machined, which is always reassuring.

Fitting it to the bike is relatively simple: open the back of the bracket and slide it over the bar, then tighten with the bolt to keep it in place. The large version fitted well on my 31.8mm bar, and for those with thinner diameter bars there is a small version or a sheath/shim that the large version can sit on. There are also two recesses within the bracket that allow for cables to sit underneath it.

It works by way of a simple spring-mounted hammer that hits the spring-mounted metal bar, which creates the 'ding'. It works well with soft to medium pressure, but if too much pressure is applied the bell doesn't ring too well; not really a 'thunk', more slightly muted.

The ring itself isn't as loud as some bells, but is still loud enough for most uses. Bearing in mind that I was using it in central London, one of the loudest places in the UK, I never found that people couldn't hear it. It has a pleasing ring, too, with a clear and tuneful tone.

Overall, I'm impressed. The Oi is a simple but really effective design at a decent price. It would be good if you could hit the hammer harder, but once you get used to it it isn't too much of an issue.

Verdict

An innovative design that works just fine and looks even better
