Bike helmets are designed to absorb major impacts and protect your head in the event of a fall or crash.

They could be the difference between life and death, so it’s vital you take good care of yours.

When should I replace my bike helmet?

A bike helmet isn’t a once-in-a-lifetime investment, and we recommend that it is replaced every three years.

However, there are situations where you may need to replace it sooner, such as after a crash or if it’s been damaged or stored incorrectly.

To keep your helmet safe and in good condition while you’re out on the road or trail, there are a few simple precautions you can take.

Is it ok to buy a second-hand helmet?

It might be tempting to save money by buying a second-hand helmet or accepting a hand-me-down for a growing child, but the risk isn’t worth it.

With a used helmet, you don’t know its history: how it’s been stored, whether it’s been dropped, or how much impact it has already absorbed. Even if it looks fine on the outside, its structural integrity could be compromised, making it unsafe.

When buying a helmet, always check for CE EN 1078 certification, and avoid any helmet without it.

You can also check the manufacturer date by looking for a stamped code inside the helmet, often beneath the padding. This is usually shown as a clock-like symbol with an arrow pointing to the month of manufacture (e.g. an arrow pointing to 3 means March).

It’s also worth noting that older helmets feature older technology, so a helmet from 10 years ago, as well as being unsafe, won’t have half as many safety features as the helmets of today.

Do I need to replace my bike helmet after a crash or fall?

Yes. If you’re involved in a collision, your helmet should be replaced, no matter how minor the impact.

The EPS foam inside is designed to absorb impact, but this also means it becomes less effective after being compressed. Helmets are single-impact by design, so replacing them is always the safest option.

This also applies if you drop your helmet from a height. For example, commuters should avoid tossing helmets under desks. Plus, kids are often quick to toss things aside once they’re done, so it’s important for parents to help put helmets on and take them off carefully to keep them safe, ride after ride.

How to Store Your Bike Helmet

Store your helmet at room temperature, as extreme conditions can compromise it’s structural integrity.

  • Too hot: Prolonged exposure to heat or direct sunlight can degrade the outer shell. While many helmets have UV protection, it’s still best to keep them out of direct sunlight to be on the safe side.
  • Too cold or damp: Cold, damp environments can compromise the EPS foam inside the helmet. Avoid storing it in places like garages, and keep it indoors instead.

How to Clean Your Helmet

Helmets can get dirty over time, whether from muddy trails or sweaty summer rides. To clean yours properly:

  • Wipe the outer shell with a damp cloth (avoid harsh chemicals)
  • Wash removable padding regularly
  • Avoid solvents or strong detergents, as they can weaken the shell and foam
  • Let the helmet air dry naturally after cleaning or heavy use
  • Don’t store it in a closed bag while damp, as moisture can degrade the padding

It may be tempting to customise your helmet, but this is not recommended. Adhesives and chemicals from stickers can weaken the outer shell, so it’s best to keep it as designed.

Perform Regular Checks

Before every ride, take a moment to inspect your helmet. Look out for:

  • Cracks in the shell
  • Compressed or dented foam
  • Loose straps or buckles
  • Broken components

Regular checks will help ensure your helmet stays in safe, working condition.

By following these simple steps, you’ll keep your helmet in great shape and enjoy a safer, more comfortable ride. Think it’s time for a new bike helmet? Shop our range over at Halfords.com.
