Shops don't insure for product liability, trail centres do insure for public liability, and their insurer can impose any conditions they dream up.
A 2 year service life for a cycle helmet isn't unreasonable, the policy probably just says 'date of manufacture' to eliminate any doubt about how long the helmet has been in service. Much simpler than getting into arguments about when exactly the trail centre took some NOS Skid-Lid out of the warehouse where it had lain unsold for the past 30 years
