I recently purchased this bike:

I was wary, but I wanted a SS/Fixed gear to ride as a commuter with a small investment. Normally I ride a Trek 6000 mountain bike so I understand what constitutes a good bike. I got it in the mail on Friday and assembled it with no issues. It seems solid and it does not have weird noises and ill fitting parts like many department store bikes. I read the component list and it actually seems to be the same bike that nashbar.com sells as their "fixie" for a bit more cash. I made two modifications. One was to install Bontrager thorn resistant tubes and the other was to install a Ritchey saddle as the original was a simple "OEM" quality saddle. The bikes are advertised at 22 pounds, but I bought the largest model which weighs in at about 23 pounds on my bathroom scale. There were a few areas where the quality had been reduced to make the price reasonable. One was the seat post whic is alright, and the other is no quick release on the wheels.
Today I took it on a 17 mile test ride. The bike was a solid performer with no rattles, shakes or other cheap bike weirdness. There are few components to have fail as it is a single speed so while durability might be an issue...I doubt it. Keep in mind that my reason for buying a fixed/ss is fitness. I want it to be a bit more difficult to build fitness and burn calories, and I am not concerned with fashionable names or looks.
I know that there are bike snobs who will shoot this down as the work of a shill selling bikes, but that is just the way this forum seems to function and you got to live with it. I posted this because in my research I have seen a lot of questions about these bikes on the forum so here is my review. to answer a few of them. The bike ain't fancy but it is not garbage and is quite functional. This is my first road bike and I am pleased with it. I may replace the seat post and the fork with lighter ones to shave off a few ounces, but it is great as it comes.
