Using the Tremor MIPS bike helmet is a breeze. First, adjust the Roc Loc Sport Mips system to get a snug and secure fit on your child's head. Make sure the helmet sits level on the head, not tilted forward or backward. When your child is out cycling, the helmet will protect them from potential impacts. Always check the helmet before each ride to make sure there are no visible cracks or damages. If it's been involved in a significant impact, replace it right away. To keep it clean, use a mild soap and water to gently wipe the exterior and interior padding. Avoid using harsh chemicals as they might damage the helmet's materials. Let it air - dry completely before using it again. With proper use and care, this helmet will serve your child well on all their cycling trips.
