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.
He's undergoing further tests.
Careflight said the boy's accident "gave his family a scare".
Hoverboards look like skateboards but with larger wheels and are designed to mimic the levitating boards which featured in the smash hit Back to the Future films of the 1990s.
They've been a popular item for youngsters this Christmas and can cost up to $2000.
