Amsterdam is not representative of Dutch bicycle culture. Amsterdam is crowded with narrow bicycle lanes that are often shared with cars.
The great thing about the Dutch bicycle structure is that it spans the entire country. It's not just the big cities. Every city, town and village has high quality bicycle lanes. You can easily bike around the country on dedicated bicycle routes in The Netherlands.
From an American perspective Munich certainly is good, but Amsterdam is still a different league. If you got the chance go there for a while.
