I've been mulling over the idea of a bike... But to be honest I'm never really all that comfortable around traffic on a bike. In a foreign city, where they drive on the wrong side of the road, with trams and all, I think it will stress me out more than it's worth.
I have my street map and can quite happily read that as I walk. After all, walking is my absolute favourite form of exercise (as I imagine cycling is for you). I have six entire days, so I'm not troubled by going any faster to fit everything in. And this way if I wear myself out walking down Albert Cuypstraat I can always get the tram home
I get three days free public transport on my iAmsterdam card - if I fancy cycling after that (when I'm more orientated) then maybe I will. If I could afford it I'd love to do a guided Segway tour... Maybe I just like people looking at me.
