Transport for LondonSkyride sensation
The mass participation bike ride will give tens of thousands of cyclists the chance to enjoy a traffic-free city centre for the day and is the capital's biggest cycling event.
The 15km route will take riders past favourite London landmarks including Buckingham Palace, Trafalgar Square, St James's Park and, for the first time, St Paul's Cathedral.
The Mayor of London, said: 'It's been a great summer of cycling in London, with more and more people discovering that ours is a fantastic city in which to go by two wheels.
'We had some 11,000 at our Hounslow event, and the central London extravaganza promises to be the biggest and best yet.
'The fantastic thing about it is the huge range of people who take part - whatever your age or ability you can come and join in our free, unique, and most importantly fun, celebration of the best way of getting around.'
A range of additional activities will complete the carnival atmosphere.
Highlights include a Skyride street zone with professional BMX riders performing tricks, and the opportunity to take a course in stunt riding.
A Skyride style zone will offer free bike make-overs, and for a memento of the day to download, go to www.goskyride.com and don't forget to smile as you pass the cameras.
