We also *do* get ones in where the suspension is working correctly. I don't have anything against manufactuers creating lower end suspension mountain bikes, but they have to be kept within a design range where things are still done right. The incidence of outright failure or improper performance is depressingly high.

But the reality of my experience on is, i've encountered a high number of these bikes where the materials and design tolerances just weren't right, where the mechanism had seized and was not properly serviceable, or horrible things (I recall a few bikes where the fork was retained as a single piece by a cheap cotter pin the size of a hair pin)

The bikes need to be kept within reasonable limits of quality and design, something too often exceeded by trying to cram features into a low price range.
