Hundreds of people will take their bicycles from the balconies to get to work by their 'iron horses'. Usually bicycles are associated as summer form of transport. In reality bicycles can be used as the winter transport as well. It is important to dress warmly and to change the winter tyres. On the 9th of February people in different cities of the world will change cars to bicycles.  The action 'By bicycle to work' will be organised in the Northern Capital to be together with cyclists all around the world.
