Emergency services were called to the Princes Highway in Kirrawee at about 9.40pm on Saturday, July 26, after reports of a crash involving a silver Toyota Echo.
The Echo had allegedly collided with an e-bike ridden by a 16-year-old boy with a 15-year-old boy riding pillion.
The boys were thrown onto the verge after being hit from behind.
The driver allegedly did not stop and left the scene.
The 16-year-old boy was taken to hospital with a fractured right leg and head injuries, while the 15-year-old boy was taken to hospital with minor injuries.
Police found the Echo abandoned on Argyle Place, Kareela, a short time later.
At about 10.30pm overnight, police arrested a 26-year-old man at a Lakemba home.
He was charged with multiple driving offences, including dangerous driving, and failing to stop and help after a crash.
He was refused bail and will appear in court today.
