Cheap bike helmets for road and trail

Looking for cheap bike helmets for road, mountain or commuter riding? Kids' helmets sit next to adult models with adjustable fit dials, vents, rotational-impact liners and built-in lights, making it easier to outfit the whole family before the next trail outing.

Are cheap bike helmets safe? Sizing and certification checks

• Look for a CPSC sticker inside any bike helmet, which shows certification to the US bicycle helmet standard.
• Measure head circumference about an inch above the eyebrows and match it to the size chart before ordering a bike helmet.
• A proper fit sits level about two finger widths above the eyebrows, with side straps forming a V under each ear.
• Replace any helmet after a crash, even without visible damage, and skip used bike helmets whose history you cannot know.

Which suits you: Kids need helmets with adjustable dials and a snug fit, while road and mountain riders may want extra vents, visors and rotational-impact liners.
