The thing is, these bikes are so heavy that even on a slight grade they can push the stand back. When happens is since the bottom of the stand is smooth theres nothing much to hold it still on a grade, and if the bike moves even a touch on a grade the weight won't allow anything to stop it. So the stand hits a slight grabby spot on the surface and the weight just rolls right thru and folds it up. I learned early on i can't set this bike on even a slight grade due to the weight. A bike this heavy scares the heck out of me because the damage that can potentially occur when 800 Lbs falls over can be seriously expensive.
