Green XJD Toddler Bike Helmet with Adjustable Fit, XS (46–51 cm)

Product details

The XJD toddler bike helmet in Green is built for the youngest riders — the size range covers toddlers from about 1 year up through age 8 — and this listing is for the smallest option, XS, fitting heads 17.32"–18.89" (44–48 cm). If your little one is just starting out on a balance bike, tricycle, or scooter, this lightweight, dial-adjustable helmet is designed to grow with them through the preschool years.

What age and head size is it for?

Suggested ages span 1 year through 8 years, for both boys and girls, but head measurement is the number that matters. This Green XS helmet fits heads 17.32"–18.89" (44–48 cm). Larger sizes are available: S fits 18.11"–20.08" (46–51 cm), suited to toddlers 1–5 years, and M fits 20.47"–22.05" (52–56 cm), suited to kids 5–8 years. The helmet line also comes in Black, Blue, Design Blue, Grape Purple, Grayish Blue, Pink, and more colorways across the three sizes.

How does the adjustable fit work?

As your child grows, turn the fit dial on the back of the helmet — right to tighten, left to loosen — to keep the fit snug, comfortable, and safe without buying a new helmet every season. The flexible strap adapts well to both boys and girls.

How protective is it?

• Outer shell: super-strong injection-molded ABS
• Inner shell: protective EPS foam
• Weight: just 240 grams, so it won't weigh small heads down

Will it keep my toddler comfortable?

Fourteen air vents plus integrated bug mesh in the front vents keep little riders cool and reduce sweating during exercise. Soft velcro padding inside feels gentle against small chins — a real plus for kids who resist helmets.

What is it good for?

Cycling, bike riding, roller and inline skating, skateboarding, and scooter use. It's a popular Birthday, Christmas, or Thanksgiving gift for toddlers just getting mobile.

The honest fit check: measure your child's head first. If it measures over 18.9" (48 cm), the XS will be too snug — move up to the S or M instead. A well-fitting helmet is the whole point, so let the tape measure, not the age label, make the call.
