The kick stand on my quick 4 is very weak, meaning if you nudge the scooter the kickstand will collapse and the scooter will fall. Today I tightened the top screw that seem to go through the kickstand hinge, using two Allan wrenches one on each side. No matter how tight I got them the outcome was the same. I use to sit on my Yadea KS5 all the time to rest and take in the sights, I can’t do it on my QUICK 4 unless I am SUPER careful, cause the kickstand will simply fold from under us. No, I am NOT fat LOL, only 120 lbs. Do you have the same issue with your QUICK 4 DrScootLittle? Can it be fixed? When I tightened that hinge screw, all it did is make it a tad harder to fully complete the folding, but it did not make the start of the folding action more stiff. In short no increase in resistance at the start of folding travel, only at the end. I will try to make a video so you can understand what I am talking about.
