Australia's cyclists have continued their dream run on day three of the Paralympics with two more gold medals.

The cyclists are responsible for all four of Australia's gold medals and are the most successful nation at the velodrome so far.

But there was also bad news for the squad, with two riders taken to hospital after crashing during the race for a bronze medal.

Visually impaired cyclist Lindy Hou and her sighted pilot Janelle Lindsay held off the British to win gold in the B 1-3 tandem sprint.

"It's been my dream and the dream has come true," said Hou.

Then Chris Scott won in the men's individual pursuit CP Div 4, weeping with relief after the race.

Australian teammates Lyn Lepore and her pilot Jenny Macpherson were also in the running for bronze in the women's sprint.

But as they tried to overtake the United States at about 50km per hour, their bike lost traction and they crashed sideways.

Both were taken off the track in stretchers and rushed to hospital, Macpherson with a dislocated shoulder, but officials were hopeful the injuries were no more serious.

Hou and Lindsay paid tribute to Lepore and Macpherson after the race.
