Frequently Asked Questions
How do I measure my child's head for the right helmet size?
Use a soft tape measure around the widest part of the head (just above the eyebrows and ears). Compare that measurement to the helmet manufacturer's size chart and allow room for padding adjustments; helmets with dial adjusters are forgiving within the listed range.
How long should a kids' bike helmet last?
Most manufacturers recommend replacing a helmet after a significant impact or every 3–5 years depending on use and storage. Replace sooner if the shell cracks, foam compresses, straps fray, or fit mechanisms fail.
Are rear lights or reflective stickers worth it for school routes?
Yes. Rear lights and reflective materials improve visibility in low-light conditions and on shaded streets, making them worthwhile for fall afternoon commutes. Choose helmets with integrated lights or add reflective stickers to increase visibility.
