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.
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.
