These city bikes are very fun you dont have to pay for an hour but you do if you go longer then an hour.
you will see many of these around Vienna and there will be tons of them in Austria these are the signs you will see for the bike stops.
and you will even see these signs on the road but you will see alot of them near the ubans and this is what i mean a metro.
this is the uban sign you will also see tons of these through out veinna all of them are blue but the train stations are different then others .
this is me riding a bike and i am going very very very fast just my wheels aren,t moving but i still am riding very very fast
