When should a child’s bike helmet be replaced after a crash or from age and wear?
A Kids Bike Helmet that has received an impact may be damaged enough to stop protecting the rider, even if the damage isn’t visible. Bicycle Helmets Business Guidance | CPSC.gov CPSC says the warning for an impacted helmet should tell users to return it to the manufacturer or destroy and replace it.

They therefore don’t establish when an unimpacted Kids Bike Helmet should be replaced just because time has passed. Follow the impact guidance and any instructions supplied with the helmet; don’t treat the lack of visible damage as proof that an impacted helmet remains protective.
