Ideal for riders using 22.2 mm flat handlebars who want a lightweight, discreet bell for commuting, shared paths and everyday riding.
The KNOG x EF Oi Classic gives you a practical bell in a low-profile wraparound design. Rather than standing above or below the bar, it follows the handlebar shape for a clean cockpit, while the integrated cable-management system helps keep nearby cables organised. The distinctive podium pink EF edition adds a little personality without making the bell bulky.
The spring-loaded actuator delivers a firm, fast strike with a clear tone and supporting higher tones, making the ring easy to distinguish when you need to alert pedestrians or other riders. Real-world use of the Oi format has highlighted its compact footprint, straightforward access and friendly-sounding ring for shared paths and busy riding environments.
This Small version is made specifically for 22.2 mm handlebars, commonly found on flat-bar controls. Installation is simple: place the bell over the bar and tighten the hex screw with the supplied key. At only 17 g, it is a sensible choice when you want the reassurance of a bell while keeping your handlebar setup tidy and lightweight.
