Bicycle Helmet Buying Guide: MIPS Technology and Safety Certification Explained

The helmet is the single most important piece of cycling gear, bar none. Every year in Taiwan, dozens of serious head injury accidents occur due to not wearing a helmet. This article provides an in-depth look at helmet technical specifications and safety certifications, helping you make the best choice.

Safety Certification Standards

There are multiple certification standards for helmets on the market, and consumers should understand the differences:

Comparing Major Certifications

Certification	Region	Test Standard	Stringency
CE EN1078	European Union	Drop impact test	Moderate
CPSC	United States	Drop impact test	Relatively strict
AS/NZS 2063	Australia/New Zealand	Multi-angle impact	Strict
SNELL B-90/95	United States	Most stringent standard	Extremely strict
Virginia Tech STAR	Academic rating	Rotational impact	Most comprehensive

Most helmets sold in Taiwan pass CE EN1078 or CPSC certification. It’s recommended to choose products with clear certification labeling, and avoid purchasing inferior products from unclear sources.

MIPS Technology Explained

MIPS (Multi-directional Impact Protection System) is the most important technological innovation in helmets in recent years.

What is MIPS?

Traditional helmets can only absorb linear impact force, but in an actual crash the head is often subjected to rotational impact force, which is more likely to cause brain injury. MIPS adds a sliding liner layer between the shell and foam, allowing the head to slide relatively 10-15mm during impact, reducing the rotational force transmitted to the brain.

The Real-World Benefits of MIPS

According to research from Virginia Tech’s STAR rating system, helmets equipped with MIPS reduce brain injury risk by an average of 23% in rotational impact testing. Many top-rated helmets from leading brands feature MIPS or similar technology (such as Bontrager WaveCel, POC SPIN).

Comparing Similar Technologies

• MIPS: the industry standard, adding roughly NT$500-1,000 in cost
• WaveCel (Bontrager): a honeycomb-structured impact-absorbing layer, a three-in-one shock absorption mechanism
• SPIN (POC): silicone pad design, fits well against the head shape
• Koroyd: a tubular foam structure, improving both ventilation and shock absorption simultaneously

Ventilation Design

Taiwan’s hot, humid summers make ventilation a major factor in riding comfort.

Evaluating Vents

Type	Number of Vents	Suitable Scenario
Entry-level	12-16 vents	General riding
Mid-tier	18-22 vents	Long-distance training
Racing	24+ vents	Racing, hot weather
Time trial	0 vents (closed)	Time trials (aerodynamics prioritized)

Note: the number of vents isn’t the only metric — the internal channel design and airflow path matter more.

Recommendations by Price Point

Entry-Level (NT$1,500-3,000)

• Giro Register MIPS: has MIPS protection, excellent value for money
• Bell Draft MIPS: lightweight design, 14 vents

Mid-Tier (NT$3,000-6,000)

• Kask Mojito³: Italian craftsmanship, excellent comfort, very popular in Taiwan
• Specialized Align II MIPS: wide-head-friendly design

High-End (NT$6,000+)

• Giro Aries MIPS: aerodynamic shape combined with good ventilation
• Bontrager Velocis WaveCel: exclusive WaveCel technology
• POC Ventral Air SPIN: Scandinavian design aesthetic

How to Wear It Correctly

1. The gap between the helmet’s front edge and your eyebrows should be about two fingers wide
2. The straps on both sides should form a V-shape, meeting below the ears
3. Chin strap tightness: you should be able to fit two fingers underneath
4. Rocking the helmet forward and backward should not cause significant movement

When to Replace Your Helmet

• After every crash: even if there’s no visible damage, the internal foam may have already compressed and failed
• Every 3-5 years: material degradation, sweat corrosion
• Be very cautious buying used: you cannot confirm whether it has previously suffered a severe impact

Conclusion

Investing in a helmet is the most worthwhile purchase you can make — budget at least NT$2,000-3,000, and choose a model with MIPS or equivalent rotational protection technology. Taiwan regulations require cyclists under 16 to wear a helmet, but for your own safety, everyone regardless of age should build the habit of wearing one.
