Not that useful or secure
I found this basket to be less than satisfactory. It has a very small base so larger items will not fit well (like my 64oz growler water bottle). I have a Knee Rover All Terrain Quad, but am tall so I have the handlebars on the last hole from the bottom  to make them high enough for me. This means that the recommended placement of below the adjustment knob is not workable as it is awkward to reach (too low) and it interferes with using the folding mechanism. Consequently, I put it on the upper part of the handlebars. As the post there is thinner, it was less secure even with the extra grip pads provided (it moves or slips down). The single attachment ring just is not enough if you need to hold somewhat heavier items like a full water bottle.<br /><br />My husband installed my Wald rectangular bicycle basket instead that I have used on a seated knee scooter for years (purchased here on Amazon). It had two attachment points on the handlebars around the center post and a third bracket the basket fits into. It is far more secure and holds much more given its wider flat bottom than the cheaper made Knee Rover model.<br /><br />I would not recommend this basket unless you do not have much to carry or are short enough to attach the basket on the lower Knee Rover post. Even then, I still think it would interfere too much with the folding knob. I returned mine for a refund.
