Don't know much about mountain bikes, but the Breezer Hybrids my wife and I own (purchased 2009 "leftover" Taiwan made models with no suspension in 2011) have been trouble free. After three thousand miles on my bike I have only had to do maintenance (cable adjustments, chain lubes, etc). With me, tool kit and dog in a big Wald basket up front, my Breezer is hauling around about 250 lbs. Oddly enough, a friend of mine said he was pleased with the quality of his Breezer mountain bike ride, and that Joe Breeze made good bikes. His rec was one of the reasons I purchased a Breezer.
