The woman, whose name was not released, said she was aquabiking -- riding an exercise bike submerged in water -- in Beaulieu-sur-Mer when she felt something moving around her legs, The Local.fr reported Friday.
The woman soon discovered an octopus had wrapped its tentacles around her legs, stopping her from pedaling.
Experts said the octopus was likely attracted by the movement in the water.
