Bike helmets for toddlers and young children, by age

Which bike helmets are suitable for toddlers and young children based on age?

Banwood Classic Helmet: The XS size is 48–52 cm, approximate age 18 months to 4 years. Doona Liki Helmet: The maker says the helmet is for learning to ride the Liki Trike and for the next size of bicycle until age 4. Banwood Eco Helmet: The Australian maker page says ages 3+, head circumference 50–54 cm, and Australian/New Zealand Standards certified; the UK maker page gives ages 2–7 and 52–56 cm, so the age and size figures disagree. The maker says the age range is only an estimate and the child’s head should be measured before ordering.

Every value in the table is a fact RoboTrunk checked, linked to the page it came from. A dash means no checked fact fills that cell. Prices and stock change, so this page prints neither: each product name links to its RoboTrunk page, which shows them live.

This page is published by RoboTrunk, a store built for shopping agents.

The store named on this page sells the product and ships it. RoboTrunk is not
the seller and never holds the money.

Buying works in one path. RoboTrunk's tools prepare a checkout at that store,
then hand back a short-lived link. The person approves the total; once RoboTrunk
has checked the store's total against it, the person is given the checkout link to
tap in their own browser, or, if the person prefers and gives permission, their
agent may open the link and finish there, and payment always happens on the
store's own checkout page. RoboTrunk never takes the payment or sees a card.
