Wiggins and Cavendish claimed the Madison world champion title at the Lee Valley Veldodrome in March, and they will return to the venue over October 25-30 after the 2016 Olympic Games in Rio de Janeiro in August.
"I grew up with the Six Day," said Wiggins. "I know it’s full-on, brilliant for spectators, as well as bloody tough to ride. It has always been a big deal in Europe so it’s only right that they’ve finally brought it back to London.
"I was gutted not to be able to ride it last year, but this year the timing just fits so I’m hoping it will be a great way to celebrate a successful fifth Olympic Games, back in London."
Wiggins described his partnership with Cavendish as the 'double act everyone wants to see'.
"It’s going to be great," said Wiggins. "This has got to be the double act everyone wants to see isn’t it? Winning the Madison at the Worlds was incredible and this might well be the last chance that people get to see us together."
Cavendish said: "The atmosphere will be right up there with the World Championships, the music's loud and the racing is brutal. It’ll be great to team up with Brad again and we’ll be going for the win."
Tickets for the 2016 ondon Six Day are available now via www.ticketmaster.co.uk/sixdaylondon, priced from £19 for adults and £6 for children.
Wiggins and Cavendish are hoping to be selected to represent Great Britain at the 2016 Games in Rio, where Wiggins would ride the team pursuit and Cavendish the omnium.
Should he win a medal, it would be Wiggins eighth Olympic medal. He currently has four golds, one silver and two bronze medals. An eighth medal would make him the most decorated British Olympic athlete in history as he would surpass the tally he currently shares with Sir Chris Hoy.
Cavendish has never won an Olympic medal, and will be seeking to add the only thing missing from his record-breaking list of victories on the track and road.
Wiggins and Cavendish have just ridden the Tour of California, where Cavendish took the final stage victory. Prior to the race, both riders joined GB team-mates for a training camp at Big Bear.
