Many people use a bike in Amsterdam and so do the tourists. You can recognize them at the coloured bikes with a rent sign in front and the wobbly way they try to find their way. I think many of them have never been biking before and certainly not in a traffic situation in a city. This a rather quiet place, but I have seen them struggling in far more crowded streets with cars which was very scary to look at. But I haven't heard yet about deadly accidents with tourists.
All those bikes are put on the streets which is becoming a growing problem. There are bicycle gagares but Amsterdam people prefer to put them in front of their home or the place they have to be. To walk in Amsterdam can be sometimes difficult making slaloms over the sidewalks.
This is a bicycle garage at a railway station.
