The bike at the centre of the 'Plebgate' row involving the Sutton Coldfield MP Andrew Mitchell has sold for more than £10,000, according to the auction site Ebay.
The former Chief Whip was accused of calling police officers "plebs" when they refused to let him ride through the Downing Street gates in September.
He's always denied using the term. All money for the sale will go to an Aids charity.
So far one anonymous bidder has pledged £200 for the bike ridden by Andrew Mitchell MP on the night of the fallout with police officers at the Downing Street gates.
The listing on Ebay states the bike is seven years old, has 18 gears and comes complete with a front basket.
It's claimed that Mr Mitchell was refused through the gates on the bike last September, which led to him swearing at police and calling two officers plebs.
The Sutton Coldfield MP was forced to resign as chief whip over the matter, despite always denying using the word 'pleb'.
Scotland Yard are investigating the dispute after a Channel 4 investigation cast doubt on the original police account of the incident.
Former chief whip and Sutton Coldfield MP Andrew Mitchell is selling the bike at the centre of the 'plebgate' row with police officers outside the gates at Downing Street.
Mr Mitchell was riding the seven-year-old bicycle when it's claimed he swore at the policemen and called them plebs for refusing to let him ride through the main gates last September.
Mr Mitchell has always denied using the word pleb. All the proceeds from the sale will go to the charity Nyumbani UK, which helps HIV and AIDS affected children in Kenya.
