COOGHI Z9 ULTRA

Z9 ULTRA is a carbon-fiber folding bicycle designed for urban commuting. Its lightweight monocoque frame and concealed folding system efficiently address the city’s “last-mile” needs. The hidden hinge integrates with the frame geometry, providing high riding efficiency when unfolded, while forming a compact, clean volume when stored. A caster wheel beneath the seatpost allows the folded bike to be pushed easily through metro gates, elevators and office spaces. The dual-tone gradient finish emphasizes structural tension and strengthens its technological identity in urban settings.
With the principle of “portability without compromise,” Z9 ULTRA combines an integrated drivetrain with optimized geometry to deliver a stable and responsive ride. Carbon fiber’s strength and durability extend product life and reduce maintenance, while the lightweight design lowers material and transport impact. Balancing aesthetics, performance and sustainability, Z9 ULTRA offers an elegant and efficient mobility option for dense cities, enabling smooth transitions between riding, carrying and rolling.
