Using your Ampd Bros Bicycle Handle Bar Side Mirror Set is a breeze. First, find a suitable spot on your bike or scooter's handlebars. Loosen the universal mounting bracket on the mirror, place it around the handlebar, and then tighten it securely. You can adjust the angle of each mirror using the 360 - degree rotatable and adjustable axis to get the best view. Make sure to check the tightness of the mounting bracket regularly to prevent the mirrors from falling off. When cleaning, use a soft, damp cloth to wipe the glass mirror. Avoid using abrasive cleaners as they can scratch the glass. Store the mirrors in a dry place when not in use to prevent rusting of the metal parts.
