Bike Helmets for Safety

Choosing a Bike Helmet That Actually Fits

Bike helmet selection has gotten complicated with all the technologies and prices flying around. As someone who rode without a helmet for my first two years of cycling — stupid, I know — I learned everything there is to know about why fit matters after watching a guy clip a curb, go over his handlebars, and crack his head on the pavement. He was fine because he was wearing a helmet that shattered on impact instead of his skull. Today, I’ll share what actually matters.

The Only Thing That Really Matters

Probably should have led with this section, honestly. Fit. A $300 helmet that doesn’t fit properly protects you worse than a $40 helmet that does. The helmet should sit level on your head, not tilted back. The straps should form a V under each ear. When you open your mouth wide, you should feel the helmet pull down slightly.

Try helmets on in person if possible. Head shapes vary — some helmets fit round heads better, others fit oval heads. What fits your riding buddy perfectly might give you pressure points.

Types and When They Matter

Road helmets prioritize ventilation and low weight. Lots of holes, aerodynamic shape. Good for long rides in warm weather.

Mountain bike helmets have more coverage around the back of your head and often include a visor. That’s what makes these endearing to us trail riders — the extra protection matters when you’re likely to fall onto rocks or roots.

MIPS Worth It?

MIPS (or similar rotational protection systems) adds a layer that reduces rotational forces on your brain during angled impacts. Worth the $20-30 premium for most riders. Most crashes aren’t straight-on.

Replace After Impact

Helmets are one-time-use protection. After any impact, replace it even if it looks fine. The foam that protects you compresses and doesn’t recover.
