Toddler Bike Helmets

For a one- or two-year-old, weight and ventilation decide whether the helmet stays on. Our lightest model is 9.3 oz with 14 vents and a mesh behind the front intakes, sized from 18.8 inches of head circumference.

    Why a toddler-specific helmet

    A toddler's head is large relative to their neck, so a helmet that feels fine on an adult can pull their head back. At 9.3 oz this is the lightest helmet we sell, and the shape is rounded rather than pointed so it rests comfortably in a trailer or a rear child seat.

    The front vents are covered with a fine mesh. At the height a toddler rides, whether on a balance bike, a scooter or in a trailer, everything the front wheel kicks up arrives at face level, and an open vent is an open door for insects.

    Sizing a toddler

    Most toddlers fall into XS. If your child measures above 20 inches, the S is the same helmet with more room, and the rear dial takes up the difference in either direction — so a helmet bought at 18 months will still fit at four.

    Toddler size ranges in inches

    XS18.8''-19.7''Roughly 1-3 years
    S20.1''-21.2''Roughly 3-8 years

    Getting it to stay on

    Two fingers above the brow
    The front rim should sit about two fingers' width above the eyebrows with the dial snug.
    Shake test
    Ask them to shake their head side to side. The helmet should move with the head, not rock on top of it.
    Washable padding
    The padding is removable. Toddlers sweat and spill, and a liner you cannot wash is a liner you will replace early.
