I don't know the brand but there are some cheaper brands that make something just above a "Bike Shaped Object" that are good for the price and rideable. I would always recommend the LBS as most will carry a cheap range for casual riders.
Saying that- the wife likes it- you don't know if she will actually like riding and hopefully it is cheap. BUT- can she get a test ride and compare it to a "Good" bike?
