switzerland to Amsterdam

[Europe]

G'day
me and a few mates are planning on buying bikes in switzerland and ridding to Amsterdam. We plan on giving ourselves 2 weeks starting around the end of september, so that we can do some stop over at some cool places.
We are keen to see some of the less touristy places around europe but we don't know anything about what sort of route we should be taking..
Any suggestions or help would be much appreciated in terms of routes or places to vist/avoid (aka big mountains)
cheers

That's quite a ride!

I believe Rotterdam (where this cycle route ends) and Amsterdam are about 30 miles apart, you could easily hop on the train with your bike for the final part to Amsterdam.
