My scooter is stuck upright and won't fold. How can I fix it?

If your scooter won't fold, this simply means that your stem is a little tight and you need to alleviate some of the tension. To do this, slowly turn the Allen bolt in the hinge block counterclockwise using a 4mm Allen key. You'll want to make sure not to loosen it too much, as that will result in a wobbly stem.
