Responding here because I recently got a dutch bike..

I got myself a Gazelle Tour Populair Oma from JCLind in Chicago. I could have got myself a Workcycles from overseas for roughly the same price, the WC are a bit pricey here in the States.

I'm liking the Oma. It's very upright, stable and slow

Hills are of course a problem but it's not too hilly here and it just goes and goes when on flats
