There are bike lanes in Amsterdam (not living there, but living in NL), but I can believe that some streets don't have any. The main difference though is that in NL, (car) drivers are used to have bikes around them (and are usually bike riders themselves). The only problem I can see is indeed tourists (not only americans) that are not used to so many bikes and to bike lanes.
