A teenager is in hospital after falling off his new hoverboard.
The 16-year-old was knocked unconscious while trying out the board and had to be rushed by ambulance to a waiting rescue helicopter at Elanora Heights on Sydney's northern beaches.
"He began to revive just as the specialist CareFlight doctor and intensive care paramedic were about to begin urgent treatment for an isolated head injury," Carflight said in a statement on Friday.
The medics then moved the boy by ambulance to Royal North Shore Hospital.
