The Oi Classic is made for riders who want a properly usable bell without the usual bulky shape. Its low-profile wraparound mount sits around the handlebar rather than projecting upwards, leaving your cockpit looking clean and preserving space for lights, computers and hands. The built-in cable management system also helps gather cables beneath the mount.
The spring-loaded actuator delivers a firm, fast strike and a clear tone with one core pitch supported by higher tones. In everyday use, it provides a pleasant, recognisable alert that is loud enough for most paths, roads and shared riding environments. It is not intended to replace awareness in heavy traffic or high wind, where any compact bell can be harder to hear.
Installation is straightforward: open the mount, position it on a round 23.8–31.8 mm handlebar, and secure it with the supplied hex screw. The included spacer helps the Large bell fit handlebars measuring 23.8–26 mm. A light-to-medium press on the spring-loaded plastic hammer produces the cleanest ring; pressing too hard can mute the sound. At just 26 g, it adds very little to your bike while giving you a practical, stylish way to signal pedestrians and other riders.
Ideal for road, commuter, urban and everyday riders who want a compact bell that fits neatly around a round handlebar without compromising cockpit space.
