I picked up a Schwinn seven months ago and am quite pleased with it. A few weeks after I bought it, it started making a noise when the right pedal swung around the bottom. I took it apart and regreased it and it has been fine every since. I only paid 229.00 for the bike and it looks like it is much more expensive. Sure the components aren't that great, but I'm into cycling to commute and for the leisure, don't want to risk having a $700+ road bike stolen.
Most bikes at stores like that however are junk. The components only last so long and the frames are ungodly heavy. And, like previously mentioned, most all of them are dual suspension.
