Seen In Amsterdam

I visited Amsterdam last weekend and among the many strange and facinating things I saw and experienced, besides meeting the almost mythical bike messenger legend of Finnish origin Hattara, this thing somehow really struck me as bit special. What is it, look at all the details, it is like a Dutch tricktrack-commuter bike or what?

I also visited Pristine Fixed Gear boutique. I didn't buy any colorful fixie components but they served really excellent coffee in the  upstairs of the shop. Go there if you're in town.
