When Do Bicycle Helmets Expire? (5 Signs to Replace Bicycle Helmet)

The Short Answer is:

Bicycle helmets should be replaced every three to five years, even if they have not been damaged or compromised. The Consumer Product Safety Commission (CPSC) recommends replacing a bicycle helmet every five to 10 years.

Bicycle helmets are essential safety gear that can reduce head and brain injuries in the event of a crash. Despite their importance, only 18% of cyclists wear helmets.

Wearing a helmet is considered the single most effective way to prevent head and brain injuries if you should somehow tumble off your two-wheeler.

However, many people are unsure when to replace their helmets. In this article, we will explore the topic, “When Do Bicycle Helmets Expire” and why it is essential to replace them.

Understanding Helmet Materials

Bicycle helmets are made up of three distinct parts: the shell, liner, and strap. The shell is the outermost layer of the helmet, which is designed to spread the force of an impact over a broader area to reduce the risk of skull fracture.

The liner is the most important part of the helmet, where the energy of the crash is managed. Bicycle helmet liners are mostly molded in Expanded Polystyrene (EPS) foam, which is designed to absorb the impact energy and reduce the peak impact on the brain.

The strap is used to secure the helmet to the head and keep it in place during a crash. Understanding the materials used to make bicycle helmets and their lifespan is crucial to ensure that the helmet provides adequate protection.

Factors Affecting Helmet Longevity

The lifespan of a bicycle helmet is influenced by several factors, including the frequency of use, exposure to sunlight, and the environment in which it is stored.

The more a helmet is used, the more it will deteriorate, so one rule for all does not work here, but three to five years is a good guide. The materials used to make the helmet, such as the foam liner, can also affect its lifespan.

The foam liner of a helmet can last for many years without any noticeable reduction in crash protection performance.

However, the helmet’s protective characteristics can improve due to advances in materials, designs, and production methods.

Therefore, it is essential to follow the manufacturer’s recommendations or replace the helmet every three to five years, depending on usage and exposure to the environment.

Helmet Safety Standards and Certification

Helmet safety standards and certification are essential to ensure that bicycle helmets provide adequate protection to the riders. The Consumer Product Safety Commission (CPSC) is a federal agency that regulates the safety of consumer products, including bicycle helmets.

The CPSC sets performance requirements for helmets to protect bicycle riders from head injuries caused by falls or crashes. The CPSC’s bicycle helmet standard uses a lab test drop of 2.0 meters on a flat anvil and 1.2 meters on a hemispheric and curbstone anvil.

Helmets that fail any of the requirements violate the Consumer Product Safety Act. The CPSC’s new safety standard for bike helmets provides one uniform mandatory safety standard that all bike helmets must meet.

The new standard requires helmets to meet the impact attenuation, retention system, and penetration resistance requirements.

The American Society for Testing and Materials (ASTM) is another organization that produces standards for bicycle helmets. The ASTM continues to produce standards for other activities such as skating, skiing, and downhill bicycle racing.

The Multi-directional Impact Protection System (MIPS) is a technology that reduces rotational forces on the brain caused by angled impacts to the head. MIPS is not a safety standard but a technology that can be added to helmets to improve their safety performance.

Inspecting Your Bicycle Helmet

Inspecting your bicycle helmet is essential to ensure that it provides adequate protection in the event of a crash. Regular inspection of your helmet can help you identify any damage or wear and tear that may compromise its safety performance.

The first step in inspecting your helmet is to look for any cracks or abrasions on the surface that show evidence of an impact. Even if you think the helmet has never been impacted, it is essential to inspect it for any signs of damage.

You should also check the helmet’s straps and buckles to ensure that they are in good condition and functioning correctly. If the helmet has been involved in a crash, it should be replaced, even if there is no visible damage.

Additionally, if the helmet is more than three to five years old, it should be replaced, even if it has not been involved in a crash.
