Cyclist Sir Chris, who won two gold medals during London 2012, said: "This isn't really for us, this is for [the public] because they've made the Games.
"They've made the atmosphere, they've supported the athletes, not just in the venues, but through the streets, and the pubs, the public venues - it's been incredible. So it's our chance to give them a wave and a thank you for all the support they've given us."
