The Bikes Direct bike I purchased last winter is a definite step up in comparison to Wal-Mart bikes. The frame is lighter, the components are better, and the bike is available in four frame sizes. Most Wal-Mart bikes are only sold in the store in one size.

I have a riding friend that only recently switched from her Wal-Mart GMC Denali to a new bike. Her bike was very difficult to keep the derailleurs shifting properly, as they would go out of adjustment after a short period of time. She would routinely have problems with her bike when we were out on the road.

This is not to say that the Dover 1.0 isn't a cheap bike with cheap brakes. Based on my experience, I would recommend a Bikes Direct bike over a Wal-Mart bike without hesitation.

Based on posts in this thread from the OP, it appears that the OP could benefit from some hands-on practice in adjusting brakes under the supervision of an experienced mechanic. I've had low-end brakes on bike shop bikes that squealed, but was always able to adjust it out.
