The Oi Classic Small is a compact bike bell designed for 22.2 mm handlebars. Its low-profile shape wraps around the bar instead of standing proud from the cockpit, making it a tidy choice for bikes where space and appearance matter. The black finish keeps the look understated, and the bell weighs just 17 g.
A spring-loaded plastic hammer delivers a firm, fast strike with a clear ring that carries several supporting higher tones. In everyday use, the tone is pleasant rather than startling, while still giving pedestrians and other riders a useful warning when you are approaching. The hammer works best with a controlled thumb flick rather than excessive force.
Installation is straightforward: slide the bell over a cylindrical 22.2 mm section, then secure it with the supplied hex key. The integrated cable-management recess helps keep handlebar cables organised around the mount. Check your bar shape before ordering, as this Small version is not intended for curved or tapered sections; it is also unsuitable for aero bars.
A good fit for commuters, urban riders and anyone who wants a lightweight, discreet bell on a bike with 22.2 mm cylindrical handlebar sections.

Low-profile Oi design
Wraps around the handlebar rather than protruding above or outwards, keeping your cockpit neat and unobtrusive.
Clear, sustained ring
The firm, fast strike produces a pleasant tone with several supporting pitches to help your warning stand out.
Thumb-friendly operation
The actuator is positioned for comfortable use without taking your hand far from the handlebar.
Integrated cable management
The mount guides cables neatly around the bell, helping preserve a clean installation and uninterrupted ring.
Made for 22.2 mm bars
This Small version suits 22.2 mm cylindrical handlebar sections; measure carefully before purchase.
Simple hex-screw fitting
Slide the bell over the bar and tighten the mount with the included hex key.
Lightweight construction
At just 17 g, it adds useful signalling without making a noticeable contribution to cockpit weight.
