Tips For Ensuring A Proper Fit

When it comes to ensuring the safety of your child while riding a bike, one of the most important considerations is a proper fit for their helmet. A correctly sized helmet will provide the best protection in the event of a fall or collision. Here are some valuable tips to ensure that your child’s helmet fits properly.

Adjusting Straps And Buckles

  • Start by positioning the helmet on your child’s head, ensuring it sits level and low on the forehead, just above the eyebrows.
  • The side straps should form a “V” shape around each ear, with the buckle centered under the chin.
  • To adjust the length of the straps, the slider buckles on both sides can be used. Make sure to even out the lengths for a balanced fit.
  • The chin strap should be snug but not too tight and should allow no more than one or two fingers to fit between the strap and the chin.

Checking For Snugness

  1. Once the helmet is on and secured, check for snugness by having your child shake their head from side to side and up and down. The helmet should remain in place without shifting.
  2. If the helmet moves excessively, try adjusting the straps and buckles again until a secure fit is achieved.
  3. Ensure that the helmet does not tilt backward, as this may impact its effectiveness in protecting the head in the event of a fall.
