As the city turned to night, you cruised through the streets on your powerful sports bike, enjoying the music pumping from your helmet and the wind rushing past. Suddenly, a gang of bikers appeared in your path. They were riding fashionable street and sport bikes, glowing in the dim light of the city. Some wore protective gear, while others chose to ride unprotected. A majority of them appeared to be male, biker guys living for the thrill of the ride.
