In addition, skateboarder Oskar Rozenberg Hallberg and swimmers Sophie Hansson, Robin Hanson and new shooting star Emelie Fast, 17, have been selected by the Swedish Olympic Committee (SOK).
SOK also gives the go-ahead for team competitions in both freestyle and medley.
Mountain biker Jenny Rissveds won Olympic gold in Rio de Janeiro in 2016, but has had a more crooked road to Tokyo.
The 26-year-old finished in 16th place in the WC 2019 after almost two years of absence due to eating disorders and depression.
It was uncertain for a long time if it would be enough to qualify for the Olympics - but now it is clear that she will get the chance to defend her title.
17-year-old Emelie Fast has also received a ticket to the Tokyo Olympics.
She won a super race in the 100 meter breaststroke during the European Championships in Budapest earlier in May, where she polished her personal best by just over two seconds and was two tenths below the Olympic qualifying limit.
Swedish skateboard star Oskar Rozenberg Hallberg will be Sweden's representative when the sport debuts in the Olympics.
Sophie Hansson recently won European Championship gold in the 100 meter breaststroke and will have to invest in new successes in Tokyo.
Michelle Coleman, who passed the Olympic qualifying limit several times already in 2019, is finally ready for the summer games.
Louise Hansson and Robin Hanson are also part of the swimming team.
The Olympics will be inaugurated on July 23.
