Radio One DJ Edith Bowman and X-Factor presenter Dermot O'Leary have teamed up with Transport for London (TfL) to promote cycling in the Capital.
They are taking part in a series of short films produced by TfL to highlight the pleasures and ease of using a bike to get around London.
From today (20 August) five films, featuring the well known faces alongside three typical Londoners, can be seen online at www.tfl.gov.uk/cycling (where the videos will be prominently featured for three months) and on YouTube at www.youtube.com/transportforlondon, while a sixth film opens in cinemas.
Each film concentrates on a different aspect of the Mayor of London's cycling revolution, such as the Mayor's flagship Barclays Cycle Hire scheme, or the new Barclays Cycle Superhighways, and tells a story around one of the people taking part.
The cinema film also features the new 'Bike Song' track by producer and DJ, Mark Ronson.
