Bicycle Helmet Ratings

In collaboration with the Insurance Institute for Highway Safety, we have rated a total of 138 bike helmets using the STAR evaluation system. Our bicycle helmet impact tests evaluate a helmet's ability to reduce linear acceleration and rotational velocity of the head resulting from a range of impacts a cyclist might experience. Helmets with more stars provide a reduction in concussion risk for these impacts compared to helmets with fewer stars.

Wearing a helmet is most important and can be the difference between life and death in the event of a crash. These ratings supplement standards by providing additional information on which helmets best reduce concussion risk. For bike helmets, we recommend any 4 or 5 star helmet. While there are some differences in impact performance within these groups, other factors such as cost, fit, and comfort should be considered when purchasing a helmet.

Notes

A lower score offers better protection.

Cost shown is MSRP for the helmets at the time of testing.

For proper fit, cyclists should position the helmet rim 1-2 fingers' width above the browline and tighten the fit system to minimize movement of the helmet on the head.

All helmets sold in the US must be CPSC-certified. This standard requires protection against catastrophic injuries in extremely severe impacts, which are rare. Several helmets are certified by additional US standards. The ratings indicate helmets that pass standards for snow sports (ASTM F2040) or skate sports (ASTM F1492).

*Anyone can sustain a head injury with even the very best head protection. This analysis is based on data trends and probabilities, and therefore a specific person’s risk may vary. This variation is likely dominated by genetic differences, health history, and impact factors such as muscle activation.
