TfL's 'Signs' ad encourages Londoners to dust off their bikes, and cycle rather than drive for short journeys around London. A cycling sign raises up off the tarmac coming alive and weaving through London, showing off the many parks and cycle lanes that the city has to offer.We follow the lead bike through the city as it passes other bike symbols through London. Apart from a bemused boy, the bikes go unnoticed by Londoners. Our lead bike settles in front of a woman's window catching her eye and prompting her to exchange her car keys for her bike.
