How Often Should You Replace a Bike Helmet?
Cycling helmets don’t last forever. The foam inside (EPS) slowly breaks down from sweat, UV exposure, and general wear. If your helmet has cracks, compressed foam, or is over 5 years old, it’s time to replace it—even if it looks fine.
⏱️ The 5-Year Rule
Most major helmet brands and the Snell Memorial Foundation recommend replacing a helmet every 5 years. The reason is simple: materials weaken and can’t absorb impact as designed. Sunlight, heat, and body oils speed that up.
💥 After Any Crash, Don’t Wait
Even a small impact can cause internal damage that’s invisible from the outside. If your helmet hits the ground—or even your handlebars—replace it immediately. The foam does its job once; it won’t protect you twice.

❓Frequently Asked Questions
Can I keep using my helmet if I never crash?
Only if it’s under five years old and shows no signs of wear. After that, the materials start to lose strength—even if you’ve never gone down.
How do I know if my helmet is damaged?
Check for cracks, dents, loose padding, or areas where the foam feels soft or crushed. If you’re unsure, replace it. Helmets are single-use protection.
Do expensive helmets protect better?
Not always. Certification standards are the same. What you usually pay for is weight, ventilation, and design—though features like MIPS are worth having for extra rotational impact protection.
