The future of stealth transportation for soldiers is here. Meet Silent Hawk, a stealth motorcycle that can run on electricity, petrol or even cooking oil. The Defense Advanced Research Projects Agency or DARPA is funding two stealth bike projects for the US military - SilentHawk by Logos and the Nightmare from LSA Autonomy. (Image: LSA Autonomy
The two concepts were showcased at the National Defense Industrial Association's Special Operations Forces Industry Conference in Tampa. Both motorcycles get hybrid engines that can run on a selection of combustible fuels from petrol to olive oil. And when the soldier needs to get close to the enemy, it can run on silent electricity.

The motorcycles get two modes - loud, which is the traditional engine noise and gives out about 80 decibels of noise levels, while the quiet mode brings this noise down to 55 decibels. (Image: Popsci)
Logos Technologies says that the motorcycle's louder mode will only be slightly louder than an average vacuum cleaner, upto 75 decibels. The Silent Hawk is capable of doing 88 kmph on rough terrains using its hybrid engine. The combustion engine can be removed, making the Silent Hawk all electric and shedding a lot of weight.
Silent Hawk is based on Alta Motors' electric racing bike, the RedShift MX. It uses Alta's chassis, while the hybrid engine is being developed by Logos. The US Special Operations Command previously tried to use an all-electric Zero MMX bike for the same purpose, but the battery only lasted two hours. (Image: Alta Motors)
It's not just the military which will soon receive steal motorcycles. It was announced in August that police forces could also be using these bikes to approach criminals undetected. (Image: Zero Motorcycles)
