Is it safe to use a cracked bike helmet?
To sum up, cracks in a helmet are never good, and usually indicate a loss of performance or the onset of some type of deterioration. The best advice is always to replace the helmet now.
How much force does it take to crack a bike helmet?
Evaluation of the helmet-only compression data showed initial cracking that occurred in the range of 100– 200 lbf. The average cracking force was found to be 140 lbf. The skull and helmet assembly could not be crushed in the compression stand even under the maximum force experienced by the load cell (470 lbf).
What do you do with a broken bike helmet?
Most local recycling programs don’t want mixed materials. So your best solution may be to take the helmet apart, put the plastic shell in your plastic recycling, break up the EPS foam for use as packing material or a soil amendment, and pitch the strap and buckle in the trash.
Are helmets designed to crack?
1) A traditional bike helmet consists of a polycarbonate shell over Expanded Plystyrene (EPS) foam—the same material found in product packaging, coolers, and many other products. 2) On impact, the polycarbonate shell is designed to crack, spreading the initial burst of energy across the entire surface.
How often should bike helmets be replaced?
every five to 10 years
The Consumer Product Safety Commission, for example, advises that unless manufacturers recommend otherwise, you should get a new helmet every five to 10 years.
How often should you replace cycling helmet?

What is helmet padding made of?
Bicycle helmet liners are mostly molded in Expanded Polystyrene (EPS) foam. For the cheaper helmets that make up the largest part of sales in the US market, the techniques are standard ones used in the industry’s “foam shops” for making all sorts of EPS parts.
Which helmet material is best?
Conclusions
- Carbon fibre helmets are generally the lightest, safest helmets out there. But they’re also the most expensive.
- If you’re on a tight budget, a thermoplastic (polycarbonate) shelled helmet is fine.
- Some expensive helmets are poor.
- If you want a really safe modular helmet, you need to be careful.
Is a helmet supposed to break on impact?
The foam material in the helmet will crush to absorb the impact energy during a fall and can’t protect you again from a subsequent impact. So even if there are no visible signs of damage, you must replace it.

Helmets were found to provide equal levels of protection for crashes involving motor vehicles (69%) and crashes from all other causes (68%). Furthermore, injuries to the upper and mid facial areas were found to be reduced by 65%, although helmets did not prevent lower facial injuries.
