In 2011 Modra made a return to the bike with new pilot Scott McPhee where they won gold in the tandem B&amp;VI 4 km pursuit at the 2011 Montichiari UCI Para-cycling Track World Championships setting a new world record of 4:17.780. They placed 2nd at the Sydney road world cup in the tandem road race and 3rd in the tandem road time trial at the 2011 Segovia world cup. In the lead up to the road world championships in September Modra suffered a broken collarbone and fractured hip due to a fall in training. His recovery was swift and he returned to the bike a month later to win the Oceania 4 km pursuit championship. In December 2011, he collided with a car while cycling to work, breaking two vertebrae in his neck and one in his spine; this accident hampered his preparations for the 2012 London Games. He won a gold medal at the games in the Men's Individual Pursuit B with McPhee.
