I prefer rear racks. In my opinion a bike looks faster and cleaner without a rack on the front.
I'm a big fan of how this rack looks: http://shop.linusbike.com/collection...bike-rear-rack
Haven't seen one in person yet though. It's very VO Porteur-like but has a little more to it.
It's on backorder on the Linus store and they told me at the beginning it should be restocked by the end of next month-ish, but it appears to be for sale here, and probably some other places too if you look. http://www.theurbanecyclist.com/prod...ycle-Rack.html
