I am looking forward to riding there, although November is not exactly a great season! At any rate it would not be possible to ride my purchased bike in Amsterdam, as it will be boxed and ready for travel. (I will only be there two nights.)

American citizens traveling abroad are allowed to bring back $800 worth of foreign purchased goods that are exempt from duties. I will only owe duty on the remainder, perhaps $400 worth. As such the duty will be trivial, perhaps $20.
