The military’s stealth motorcycles are as quiet as an electric toothbrush - electric toothbrush cost

The military is funding stealth motorcycles, which will allow cyclists to quickly approach unsuspecting enemies.
The motorcycle runs at 55 decibels
A level or typical conversation about an electric toothbrush --
But the speed can still reach 80 miles per hour.
It is very quiet because of the electric motor.
Motorcycle also has two features
Wheel drive to improve traction on gravel, sand or any challenging terrain.
The narrow size of the motorcycle allows them to drive in the forest or some other place where military vehicles cannot go.
"With skilled riders, you can basically find them anywhere on Earth," said Alex Dzwill, chief engineer of SilentHawk, a motorcycle from defense contractor identification technology.
Limited range of action of electric motor
Silenthawk lasts for two hours and the other bike, NightMare, has 60 miles of power.
As a result, motorcycles are modified with a hybrid engine that can burn almost any type of fuel, such as gasoline, jet fuel, kerosene or diesel.
"You don't always get quality gasoline from Shell gas stations when you're on a mission.
"You will be driving in dangerous terrain in different areas," Dzwill said . ".
The idea is that these hybrid engines are as loud as vacuum cleaners and can be used in tasks that don't require quiet. Using the back-
The Up engine increased SilentHawk's range to 170 miles.
Logos Technologies presented a prototype of a quiet motorcycle at this week's defense industry trade show, along with Nightmare Maker LSA Autonomy.
The two companies are still demonstrating and testing the technology for the Defense Advanced Research Planning Agency, which will decide whether to continue developing motorcycles.
Both companies said it was too early to make any estimates on the cost of motorcycle production.
If a motorcycle is suitable for civilian use, one possible use is to provide a quiet way of getting to work by car for commuters.
According to Dzwill, the hybrid engine can be turned on when the motorcycle is parked, which will charge the battery and allow a silent home that is no louder than brushing your teeth.
