I am guilty of having ridden my wife's mixte more than she has. It's still a work in progress and some day I expect it will really be 'her' bike. But right now I'm busy fussing over it. It's a mid 80s Raleigh Sprite in black. It was my mom's. I had new wheels built for it (dynamo front hub, SA 3 speed rear), put a pair of Paul levers on it I had sitting in my parts box, new VO saddle, VO bars, new seat post, new pedels. The frame, crank set, fenders, stem and brakes are original. It's a beaut.
If they made them big enough, I'd definitely ride a mixte more than I do now.
