Motobecane, Windsor, Dawes, Mercier (road) sold on BikesDirect are all owned by BikesDirect and are made by Kinesis...mostly in Taiwan. Kinesis makes quality bikes for a lot of the mainstream brands and they are of equal quality. I picked up a Windsor 29er this summer from them and am quite happy with it.
Remember though, there is a trade-off when buying a bike online. The bikes come in "dealer ready" condition and take some good mechanical skills to assemble correctly. Of course you could pay a Bike Shop to do it, a good shop will not turn down a chance to earn a customer on service and accessories...even if you didn't buy the bike from them. You also don't get to test ride one unless you live near a Cycle Spectrum (also owned by BD).
But if your comfortable with the lack of test ride and service...they are good bikes that are well equipped for the money.
