Mixtes are a ton of fun to ride. I have an 80s Japanese mixte road bike that I converted into an around-town single-speed cruiser. Before:



And after:



Since it has skinny road bike tires and relatively high gearing compared to your average fat-tired townie, it goes nice and fast even though I think it looks like a little old lady bike. My new one is pretty much the same as the "before" picture, only a dark maroon, and I'm going to set it up with moustache bars, a lower stem, and no rack or baskets. And my husband is secretly wanting a mixte because they are a little more stable than a regular road bike for carrying panniers, etc. (I don't think he wants a pink one, though.)
