the case of nearly being run over described above is a function of multi-use occuring in/on bikelanes/sidewalks: cyclists, handicap vehicles (the 'little euro-midget car'), and mopeds are allowed usage of the cycling lane. this brings up some unique points of caution while riding in the city: being aware of fast-moving mopeds/scooters overtaking you while in the bike lanes (esp. pizza-delivery guys); tram tracks crossing at intersections; and (no joke) stoned/drunk tourists on main thoroughfares (esp. the rokin, damstraat, leidsestraat, around the museums, etc...) i'm a sometimes messenger here, and i avoid those streets at all cost
I just found that in the city itself, especially inside the canal zone, there was just too much to see and too much happening on the street to safely ride a bike. However, its the best way to get around, if you are not sightseeing, to the various suburbs, even to the airport.
What a cool bike friendly place. I can't wait to go back.
