F-22 Raptor

The F-22 is probably the best known fighter-jet in the world and its fame and reliability means that it comes at a pretty high price tag. At just over $211 million it’s the most expensive fighter jet in the world, but that hasn’t put the US army off – they have a fleet of 188 F-22s at a total cost of $79.2 billion.

El Tucura Downhill Trike

 The motivation behind the El Tucura (The Grasshopper) trike was to give paraplegic users the opportunity to enjoy the thrill of off-road downhill mountain biking, promoting it as an integrated nationwide sport. A crank handle drive means hands are free for steering while accelerating and three 180mm disc brakes and a 250mm suspension give added control on those extreme downhills.
