There are a number of ways to get around London but few are as fun - or dangerous - as how these gents manage it.
In order to highlight the lack of free urban spaces in the capital, two trial bikers performed incredible tricks in places you wouldn't think a Boris Bike could reach.
Andrei Burton and Joe Seddon, partnered up with award-winning free-runners Tim Shieff and Paul Joseph to dazzle the thronging London crowds.
As well as traversing the lions in Trafalgar the entrance to Marble Arch tube, the four lads even went to the dizzying heights of the rooftops of Regent's Street.
