Ride This Stealth Bike Wherever You Want Without Being Seen

So it might not be the best idea to try and pedal your way onto a secure military base, but engineer Brano Meres' experimental X-9 Nighthawk bike frame looks like it would be as invisible to radar as the old F-117 stealth fighter was.

Like anything supremely awesome, the X-9 Nighthawk is made with a lightweight carbon fibre skin that surrounds a core made from a material partially composed of Aramid, a synthetic fibre used in body armour fabric. In this application it was moulded into a strong honeycomb pattern that provides ample structural integrity with minimal weight.

In fact, the X-9 frame weighs just over three pounds. That's roughly the same as a couple of iPads, which is simply amazing. While there's no word on whether or not he intends to put it into production, Brano's primary goal for the bike was to experiment with building a frame using the same honeycomb sandwich panel techniques as is used in the aircraft industry. And from the looks of it, he succeeded with flying colours. [Brano Meres Engineering & Design via Bicycle Design via Gizmag]
