The U.S. Army definitely wants hoverbikes. Infantry are the core of any military--foot-slogging armed grunts ready to bring pain to whoever they may face. But they are, by their nature, constantly outmatched. Tanks have more armor and heavier guns, planes fly well beyond their reach, and even defending ground troops often get bunkers or fortifications to protect themselves. How do troops on the ground overcome that? One way is to put them in the air. On hoverbikes.
