A strong choice for commuters, urban riders and road cyclists who want a discreet bell that preserves valuable cockpit space.
The Oi Classic is a low-profile bike bell designed for riders who want an effective warning bell without the usual bulky shape. Its wrap-around mount sits around the handlebar rather than projecting upwards, while the integrated cable-management design helps keep the cockpit tidy. At 26 g, it adds very little weight and takes up minimal handlebar space.
A spring-loaded actuator delivers a firm, quick strike, producing a clear tone with a core note and supporting higher tones. It is loud enough for everyday path, road and commuting use, while its pleasant sound is less aggressive than many traditional bells. As with any bell, busy traffic, strong wind and headphones can reduce how easily it is heard, so ride defensively and allow plenty of room.
Installation is straightforward: place the bell over the bar and tighten the hex screw. The included spacer helps secure the bell on 23.8–26 mm handlebars, while the large size also fits 25.4 mm, 26 mm and 31.8 mm bars. Check your handlebar diameter before ordering, particularly if you use an aero-shaped bar rather than a standard round section.
