KOKO: Born to Fly

Air resistance is the single most critical factor separating a fast bike from one that slices through the wind with the grace of flight. KOKO—meaning “to soar, to fly” in Māori—embodies that vision. Designed to ignite pure speed and aerodynamic superiority, the KOKO Aero Road Bike delivers a ride experience so exhilarating, it will leave you smiling from ear to ear.

Advanced Aero Engineering

Building on the proven aerodynamic pedigree of the RERE, the KOKO advances the formula with Kamm-Tail profiles strategically integrated into the downtube. These structural refinements yield a 13.35% increase in bottom bracket stiffness and an impressive 35.64% increase in head tube stiffness, translating into precise handling and enhanced power transfer.

Pair this with our aerodynamically optimised MANA handlebar system, and you get an uncompromising race machine designed for maximum performance and minimal drag.

Tunable Ride Compliance

The KOKO doesn’t just fly—it adapts. Featuring an adjustable dual-position seat clamp, riders can tailor compliance from race-ready stiffness to a buttery-smooth ride, depending on terrain or personal preference.

Uncompromising Performance Details
• Latex Mandrel construction in the front triangle delivers a flawlessly compact, rigid layup.
• The T47 bottom bracket ensures a highly efficient power transfer platform.
• Quick-Fit headset spacers allow rapid adjustment without disrupting cable integration.
• Vibration-dampening seatstays and seatpost enhance comfort without compromising performance.
• Up to 32mm tire clearance ensures versatility across a range of road conditions.

From elite-level racing to spirited solo efforts, the KOKO is designed for those who refuse to compromise.
