The Oi Classic Bike Bell, including the EF Small edition and Large variant, reimagines the traditional bike bell with a sleek, wrap-around ring design that complements your handlebars. The Large version (approx. 26 g) fits bar diameters from 23.8 mm to 31.8 mm, while the Small (17 g) suits 22.2 mm bars. Crafted from 7075 aircraft-grade aluminium with a spring-loaded plastic striker and integrated cable management, it produces a pleasant yet clear tone that punches above its size REI+1. Installation is swift—simply pop it over the bar and tighten a single hex screw; spacers ensure a snug fit. With its minimalist aesthetic and refined sound, the Oi Classic elevates both form and function on every ride.
