About this helmet

A White Astronaut design from XJD, filed under Bike Helmets, with suggested ages of 2 through 8 Years in the current fit data.

Age is only the first clue to sizing. An adult should confirm the child can get on and off the bike smoothly, reach the controls with ease, and remain in full control before heading out.

Post-assembly or adjustment, an adult should walk through fasteners, tire condition, steering, saddle placement, and braking response before every ride. Pair with age-appropriate protective gear and attentive supervision.

For lasting value, line up the verified adjustment features above with your child's needs now and the stage that follows.
