I'll put in a plug for the gorgeous chocolate brown/gold metallic Co-Motion Robusta that's sitting on the floor at my LBS (Sunshine Bikes in Springfield, MO). We rode it last Saturday morning and met up with our local tandem club. The bike was part of Co-Mo's catalog shoot, and then used as a demo/show bike. It's got a good price tag on it but unfortunately the price exceeds my stoker's sensibilities. (but not mine!)

I will say this about the color: it glows in the sunshine and it's a stoker magnet. ;-)
