Sir Chris Hoy survived a scare before winning his fifth Olympic gold medal on that day in 2012.
Hoy, Philip Hindes and Jason Kenny won the three-lap three-man team sprint in London in a world record 42.60 seconds, beating France in a repeat of the final four years earlier in Beijing.
Hindes got off the track after a poor start in qualifying to help Britain to two world records and Olympic gold.
In an eventful start to his Olympic career, the special starter wobbled out of the starting gate and lost control of his bike before falling onto the track at the start of the first corner as his team-mates rolled past him and officials restarted the heat.
The 19-year-old German-born rider of a British father, who joined the British Cycling Academy in October 2010, said: “We said if we get a bad start we have to crash to get a restart.
“I just crashed, I did it on purpose to get a restart just to have the fastest ride. I did it. So everything was really planned.”
British Cycling indicated that Hindes’ comments from a man who only started learning English after moving to Manchester to train at the velodrome, while the International Cycling Union confirmed the result was out of the question and Britain took gold ahead of France won and Germany bronze.
There was no rule settling the incident and no appeal was possible, with France accepting the final outcome.
For Hoy, his fifth Olympic title was emotional and his best in front of a partisan audience including the Duke and Duchess of Cambridge, Prince Harry and Prime Minister David Cameron.
The 36-year-old from Edinburgh said: “When I crossed the finish line I didn’t have to look at the scoreboard, I knew we’d won when I heard the thunder.
“I thought my first win in Athens would be the most memorable for me, but this is by far my biggest win. It’s an incredible feeling.”
The keirin five days later brought Hoy a sixth and final Olympic gold, a British record until Kenny won his seventh in Tokyo 2020.
