This recommendation is based on the typical rate of physical wear and tear, the aging of the materials, and advancements in technology and safety standards.


A helmet’s primary function is to absorb impact energy during a fall or collision. Over time, the impact-absorbing foam in a helmet begins to degrade and will not offer you the same protection it did when new. And unfortunately, you often can't see this degradation with the naked eye.


A helmet is an investment in your safety. Regular replacement, along with careful inspection and maintenance, is a key aspect of ensuring your helmet can do its job—protect your brain in the event of an accident. So, if it’s been a few years since you last got a new helmet, it might be time to start shopping. Your safety is worth it!


Do Bicycle Helmets Have An Expiration Date?


Do Bicycle Helmets Have An Expiration Date?

One crucial question that cyclists often ask is: "Do bicycle helmets expire?" The simple answer is yes, bicycle helmets do expire over time. While they might seem like robust, timeless pieces of gear, their lifespan is not indefinite. Various elements, both visible and invisible, contribute to the degradation of a helmet's safety features, prompting the need for its replacement.


Manufacturers typically recommend replacing a bicycle helmet every 3-5 years, depending on the helmet's exposure to various elements and how frequently it's used. This recommendation is rooted in the understanding of how the materials used in the helmet, especially the vital Expanded Polystyrene (EPS) foam, degrade over time.


EPS foam is the core component that absorbs impact during a crash. Over time, even without external impacts or visible damage, this foam can become less effective at absorbing shocks due to natural degradation processes. This degradation may be exacerbated by exposure to certain chemicals, like those found in sunscreens or bug sprays, or through exposure to extreme temperatures.


Other components of the helmet, like the plastic shell and the straps, can also degrade due to wear and tear, UV exposure, and weather conditions. Prolonged exposure to harsh sunlight, for instance, can make the plastic brittle over time, reducing its ability to protect and hold the helmet together during an impact.


So bicycle helmets do expire, and it's essential for your safety to pay attention to their lifespan and replace them when necessary. Even if your helmet appears to be in good condition, if it's beyond its recommended lifespan, it's time to invest in a new one. This is a small investment to make considering the critical role a helmet plays in protecting your head and potentially saving your life in the event of a crash.
