Here’s a practical guide to help you pick the right adult bike helmet — because for safety gear like this, fit + certification + comfort matter more than looks alone.
What to consider when picking a helmet
• Correct size and fit
- Measure your head circumference (just above eyebrows and ears) — this helps you choose the right helmet size.
- When you put the helmet on, it should sit level on your head and cover your forehead — the rim should be about 1–2 finger-widths above your eyebrows.
- The helmet should feel snug but comfortable, with no large gaps between foam and your head.
