Lovingly called the Pirate-Ninja because they couldn’t decide which of the two was more badass, the Tern Eclipse X20 is quite possibly the world’s fastest folding bicycle. It’s a super light and super sleek 24″ bike that is built for speed. The Eclipse X20 features Sapim CX bladed spokes, SRAM Rival drivetrain, a FSA MegaEVO BB386 Crankset, and a very wide 25″ – 107” gear range. This light bike weighs only 10.7 kg (23.6 lb). Available Spring 2013.
