The Team GB athlete stated that the carbon-fibre cycle she used in the keirin event at the London 2012 Games was sold without her permission.
"I'd said I was going to buy the bike but they've bloody sold it and without telling me," she told The Sun.
"I don't know who sold it or who they sold it to but it's gone and now I can't have it.
"Luckily I got my pump and my bottle cages from it but that is all I've got - oh, and a couple of pedals and a spare inner tube.
"I'd said I was willing to buy the bike - they sell them at the end of the season because obviously you get a new one each year. But no, it's already gone."
Pendleton previously fell out with cycling chiefs after her relationship with team analyst Scott Gardner was deemed unprofessional.
The couple are now engaged and are expected to marry in 2013.
Victoria Pendleton will appear as a contestant in the upcoming tenth series of Strictly Come Dancing.
