With Tern's Eclipse X20, you get the best of both worlds on your commute. This bike packs tons of high-speed, road bike swagger into a convenient and commuter-friendly package. The light, responsive aluminum frame handles and feels like a high-performing road bike, with power transfer and efficiency to spare. Like all Tern bikes, the Eclipse X20 uses their N-Fold technology to provide a super compact bike that can be folded or opened in less than ten seconds. SRAM's Force and Rival drivetrain components are renowned throughout the cycling world for the fast shifting and solid, positive action. Pair that with wide-range gearing and Tern's custom double chainrings and this bike flies up climbs and hammers on the flats. Lightweight Kinetix wheels, wrapped with high-quality Schwalbe tires, feature feathery aluminum rims for near-instant acceleration, and stainless steel cartridge bearings that roll smooth as silk. And keeping with the no-compromise ethos, Tern equipped the Eclipse X20 with German-designed Ergon grips and a supportive Kore saddle.
