Someone else ask about these the other day.....

They look like nice bikes, though they have the flat bar I dislike so much. But on their plus side, they have 650B wheels and tires that will probably be better for some one < 5' 4" or somewhere there about.
I've also been trying to get my wife to check out these bikes............

I'd actually get one for myself if she does buy it. I feel that if I'm on that same type frame that it might curb my need for speed somewhat. And note that most have sweptback bars that IMO will be more comfortable. Wheel sizes might vary on those, but I think most are smaller diameter than 700C.
