Bike Helmets

Bike helmets are pieces of safety equipment designed to protect your head in the event of a fall or crash. They consist of an outer shell and interior protective liner made of polystyrene foam to absorb impacts. Manufacturers have created a suite of technologies to improve safety like MIPS, designed to dampen rotational trauma.

Types of Bike Helmets

You'll want to choose the type of helmet that suits your style of riding:

If you're concerned about bike safety, also see our selection of bike lights, reflectors and mirrors.

More Considerations

Look for some important features as you pick your helmet:

  • Ventilation: More vents increase wind flow, cooling you down.
  • Visors: Some helmets have a sun visor built in to keep your eyes shaded.
  • Face protection: Mountain bike helmets often have full face protection and a wraparound chin bar.

Bike Helmet Fit

Helmets should fit snuggly but not be uncomfortable. To get the right fit, first adjust the wheel or strap in the back. Then, buckle and tighten the chin strap. To test the fit, open your mouth wide. The helmet should press against the top of your head.

When to Replace your Helmet

Bike helmets are designed to absorb one impact. If you're been in any type of accident, it's best to get a new helmet even if it looks OK. Crash-free helmets should be replaced after five years as UV, weather and age can cause them to degrade.
