How To Choose The Best Road Bike Helmet Under $100?
When choosing a road bike helmet under $100, here are some things that worth your consideration:
- Its weight: Some helmets weigh even less than 1 ounce, wearing which you almost feel no weight. However, a helmet does not need to be that lightweight to be comfortable. I would say less than 10 ounces is a reasonable weight for a helmet that is both comfortable and protective.
- Its ventilation: Most road bike helmets adopt a trail-inspired style, which has a lot of large vents for air, heat, and humidity inside to circulate. This design keeps your head dry and cool all day long of cycling.
- Its protection: MIPS technology is the priority when it comes to bike helmets of all prices. Besides, the outer shell should be hard and sturdy enough, and the inner pad should be soft and thick enough.
- Its look: Appearance should also be a factor worth considering. It’s better to wear a cool helmet rather than an ugly-looking helmet.

FAQs
Do bike helmets expire?
No, they don’t. However, you should replace your helmets after an impact or when it looks not protective enough (after 5 - 10 years).
What does MIPS mean on a helmet?
MIPS stands for Multi-Directional Impact Protection System - the system reduces dangerous forces transmitted to your brain. It is typically featured between the outer shell and the inner pad. MIPS absorbs all the energy and eliminates almost all the forces in case of impact, so it protects your head and your brain.
How long should you keep a cycle helmet?

Why should you wear a bike helmet?
While bike accidents are not as serious as motorbike accidents, they are still very dangerous. Every year in the US, about 800 cyclists die from accidents. A bike helmet prevents your head from hitting directly to a hard surface or even to rock. A bike helmet with MIPS is even better - it prevents force from transmitted to your brain, lowering the risk of brain damages. Helmets are designed to save you from injuries and death.
How do you measure your head for a bike helmet?
You can use a flexible tape measure to measure the perimeter around your forehead. Or you can use a string, then measure the string with a normal straight ruler.
