Wiggins, 36, was named on Thursday as part of the eight rider men's track endurance team in British Cycling's Olympic Podium Programme squad.
The programme supports the country's elite cyclists on the road to major competitions like the world championships and Olympic Games.
British Cycling said they were giving Wiggins flexibility as he continued to "consider the direction of his future".
Wiggins became Britain's most decorated Olympian at the Rio de Janeiro Olympics, where he won the team pursuit to take his tally to eight medals, with five golds.
