Koga, a well-respected European manufacturer, offers a surprisingly wide range of expensive touring bikes. Every one of their touring bike models has upright bars.

Given that Europeans have a long history of bikes being ridden by adults as a matter of course, I think the Koga designers know what they're doing.

I like the front and rear kickstands. Makes sense on a bike meant to be used for loaded touring.

(Looking at the picture below, it reminded me of a scene in the first Crocodile Dundee movie: "Call that a knife? This is a knife!")
