Two men. One bike. One Oyster card. One destination.
This video, from Currys, sees Londoners Dan and Fin race from Crystal Palace to King's Cross.
While Dan takes the public transport option, Fin pedals his way northward.

Who will beat the obstacles to get to King's Cross first? Watch the video to find out.
