How to Choose the Safest Kids Bike Helmet

A properly fitted helmet is the most important piece of kids safety gear. Whether your child is learning to ride a 12 inch kids bike, cruising on a kids beach cruiser, or building confidence on a kids mountain bike, the right helmet helps keep them protected—and riding with confidence.

At retrospec, we design affordable kids helmets with fun designs that meet safety standards and actually fit the way they should. Here's how to choose the safest kids bike helmet for your rider.

1. Look for Certified Safety Standards

Not all helmets are created equal. For full protection, always check that the helmet is certified to meet or exceed safety regulations.

What to look for:

  • CPSC certification: Required for kids bike helmets sold in the U.S.

  • ASTM or EN standards: Optional but helpful for multi-sport use

  • Shell construction: In-mold shells offer strong impact protection with less weight

All retrospec helmets—like Remi Youth, Scout, and Dakota Youth—are CPSC-certified and designed for all kinds of kids active play.

 


2. Measure for the Right Fit

A helmet that doesn’t fit properly won’t protect properly. Here’s how to measure a child's head for helmet fit:

  1. Use a soft measuring tape around the widest part of your child’s head—about an inch above the eyebrows.

  2. Compare the measurement (in centimeters) to the helmet’s size range.

  3. Look for adjustable dials and interior padding for a snug, secure fit.

Size ranges:

  • Small: 48–52 cm

  • Medium: 52–56 cm

  • Youth helmets like Remi and Dakota are easily adjustable and great for growing heads.

3. Prioritize Fit and Comfort

A helmet should feel secure without squeezing. Test the fit:

  • The helmet should sit level, low on the forehead

  • Buckled straps should form a “V” just below the ears

  • The chin strap should be snug, allowing one finger beneath it

  • It shouldn't rock back and forth when your child shakes their head

4. Style and Visibility Matter

A helmet your kid loves is a helmet they’ll actually wear. Affordable kids helmets with fun designs help make safety part of the routine.

Features that help:

  • Bright colors or reflective elements for visibility

  • Graphic designs or classic matte finishes

  • Integrated visor or wide shell for sun protection

Pair helmets with kids bike accessories like a bell or basket to help your child feel excited about every ride.


5. Add Pads for Full Protection

For younger or new riders—especially those learning on a training wheels bike—add elbow, knee, and wrist protection.

  • Let your child choose the color or design

  • Make it part of their routine: “No helmet, no ride”

  • Set the example—wear yours, too
