Cycling gold medallist Bradley Wiggins has denied calling for a new law forcing cyclists to wear helmets.
Wiggins suggested at a press conference that making helmets compulsory would help protect cyclists on busy roads.
He has since written online saying he wasn't calling for a change in the law he was just saying what he thought would help.
He was asked about riding on busy roads after a cyclist died when he was hit by an Olympic bus near the Olympic park.
It's not known yet whether the victim was wearing a helmet but Wiggins said making it illegal to cycle without one would make things safer.
The accident happened close to the hockey centre and velodrome on Wednesday evening.
The 28-year-old man died when he was hit by a bus which was carrying journalists to the Games.
Wiggins grew up in London and said it can be really dangerous: "It's got a lot busier since I was riding a bike as a kid around here and I got knocked off several times."
He added that wearing a helmet and having lights on your bike is a great way to help yourself stay safe on the road.
