Cycling in the Vondelpark is a bit of an experience, it is something like an arcade game.
The Sarphatipark is a really nice and lovely park to hang out.
Going cycling across the dike towards Volendam might be nice. The town itself is very touristic and not really for me.

If you like beer, De Prael (Oudezijds) is a good bar. It is a workplace for people with a distance to the regular labor market, as they say in The Netherlands. And the beer/brewery is really great.
