Nice bike. It needs a bit of dirt on it though
The dutch elastic straps your fitted are the posh type. The basic Dutch type are cheap plain black rubber ones in two strands over the rear carrier, the ones which get brittle after a while and crack.
I thought I'd all treat you on a nice collection of old school dutch bikes: http://www.waanders-rijwielen.nl/WebWinkel/omafiets.html
The type of bike on with you can hang two large bags of shopping on either side of the handle bar while holding and umbrella to protect both yourself and your friend on the back from the rain while driving swifly done a cobble stone road.
