It's pretty sturdy, as long as you make the straps nice and tight. It's to dark to show you how now but ill uploa how I do it in the morning. The bars actually for being pretty thin can hold a decent amount of weight. I've had it on with my basket strapped to it (40lbs) and 4 bmx roughly 30 pounds a piece so it does the job. The only thing is do not go thru a car wash with it my first one the straps on it broke an it flew off in the car wash tunnel. Other than that it's been perfect for me, and I daily it with and without the basket
