Of course, my wife lives the idea. We have a tandem, and we love riding it, but she yearns to ride her 1/2 bike now and again, mostly on the 20 mi urban rides. Usually the field is big enough that she can hang with some "C" riders during the occasional sprint zones. But when the field is small, I kinda look like the dorky guy for most of the rides. But at $299, there is not fear of us ever getting one.
The thing that scares me most it the retraction! I can just see that thing getting caught in the rear spokes at speed. There goes a rear wheel. Replay that video and look at the retraction sequence. I can't believe they didn't do a retake on that so that she didn't have to pull it a few time to get it to retract! Or maybe they did, and just took the best of all the retakes.
