The Brano Meres Engineering X-9 Nighthawk single-speed bike made it's debut at the Berlin Fahrradschau 2012 where it's F-117 Nighthawk stealth fighter jet-inspired inspired look left the audience in awe. Featuring the Meres-designed S72 saddle and equipped with the Gates carbon belt drive system and the Atomic22 Infiniti3D Guard Dogs security wheel skewer, this bike is seriously ready for some late-night stealth riding. As of now, the bike remains a concept, but may see production in the future.
