As in a lot of European cities, cycling as a means of transport has gained a lot of ground recently. The Citybike system is in place and the city streets have been adapted for cyclists.
So how do you get on one? Register online with your credit card or do it directly in the tourist office.
On top of that, its cheap. For only €2 a day you can cycle to your heart’s content for one hour without any extra charge. It could also be a good way to burn off all that sachertorte.
