Tighten the big allen bolt that goes through the joint. I do like their padding and the faux fur lining is a good amount of warmth. (Also remember that these are crocs so they are made wide. I put this on my motorized beach cruiser and I love it. So greift meine Partnerin lieber zur Sensitiv Variante. Benutze den Heckträger für zwei Cube Reaction Hybrid Ebikes (2019) mit im Rahmen integrierten Akku. ) before I had to recharge them. They feel a bit loose in the mornings but after being on my feet all day they accommodate the swelling. Didn’t want to drill holes in the bumper so I attached it to the grill. Fit perfectly and are super warm and cozy.
