Congrats on your new bike, I hope it works out very well for you.
Almost all bikes no matter if you get it from your LBS or Bikes Direct are made in China these days and in the same factory that puts out the brand name bikes puts out the "generic" brands, I much rather call generic brands decal brands, they are simply a decal with no real company behind it. There have always been generic or decal brands, some of the old time favs were Nishiki and Centurion, both were top notch generic/decal brand bikes.
Who cares if Bikes Direct puts on last years model of Dura Ace of Ultegra? I didn't hear anyone last year complaining about those groups then or this year on their 2013 brand name bikes!
I have a friend who bought a Motobecane Titanium road bike from Bikes Direct (BD) about 3 years ago and he still loves his bike and he rides it a lot at around 5,000 miles a year. He loves his bike so much that after test riding it myself I almost bought one of the Ti models but BD couldn't get any stock for over a year so instead I found a good sale price on a Lynskey. Had BD had it in stock when I wanted it I would have bought it without hesitation that's how good that bike rode and how good it's worked, not to mention it would have saved me nearly $800! I would have gotten the BD bike mail order, but I also got the Lynskey mail order and no complaints about that bike I got.
BD does sell a lot of bikes, but considering how many they sell they have a very low complaint ratio.
Warranty issues, the only warranty issue I ever heard on a forum (not saying this was ever the only problem BD ever had) was a guys chain was somehow screwed up from the factory and a link was stiff, upon pedaling it for about 5 miles it froze completely causing the rear derailleur to sheer off and into the spokes. BD replaced the wheel, chain, derailleur hanger, and the rear derailleur. From that experience I read I recommend to anyone buying a bike by mail order to first assemble it themselves since that's really quite easy, then take the bike down to an LBS to have it "tuned up" to make sure all things are working right and aligned properly. Even though I've been around bikes a long time I took my Lynskey down and had it gone through, it cost $30 which was worth the piece of mind. By the way full assembly of a bike out of the box which will include full adjustments usually cost around $75 to $100, so if you not mechanically inclined in the least bit then just take the box in and have someone do it for you.
