Cycling is a fantastic way to stay fit, explore the outdoors, or commute, but it’s not without risks. According to the National Highway Traffic Safety Administration, over 1,000 cyclists lost their lives in the United States in 2020, with countless others suffering injuries, many involving the head. Helmets are a cyclist’s first line of defense, yet not all helmets offer the same level of protection. Terms like MIPS and EPS often pop up when shopping for helmets, leaving many wondering what they mean and why they matter. This guide takes an in-depth look at the differences between MIPS (Multi-Directional Impact Protection System) and EPS (Expanded Polystyrene), how they work together, and what cyclists need to know when choosing a helmet from a bicycle helmet supplier or manufacturer.
Cycling combines freedom, exercise, and adventure, but safety remains paramount. Head injuries are a leading concern—data from the CDC shows that traumatic brain injuries account for a significant portion of cycling-related hospitalizations. Traditional helmets have long been effective at preventing skull fractures, but modern research reveals that many crashes involve more than just direct impacts. Rotational forces, which twist the brain inside the skull, are common in falls and collisions, often leading to concussions or worse. This is where EPS and MIPS come into play. EPS is the foundational material in nearly every cycling helmet, while MIPS is an innovative technology that enhances protection. Whether you’re a weekend rider or a competitive cyclist, understanding these terms can help you select a helmet that offers the best safety from bike helmets factories or retail stores.
EPS, or Expanded Polystyrene, is the lightweight, white foam you’ll find inside most bike helmets. It’s been the industry standard for decades, valued for its ability to absorb impact energy and protect the skull during a crash. EPS is produced by expanding polystyrene beads with steam and molding them into a solid, yet crushable, structure. This material is ubiquitous in helmets from cycling helmets manufacturers because it’s effective, affordable, and keeps helmets light—typically weighing between 250 and 350 grams.
When you crash, EPS functions like a crumple zone in a car. Upon impact, the foam compresses, absorbing and dissipating the energy from a direct, linear hit. This reduces the force transmitted to your skull, helping prevent fractures and severe trauma. Imagine dropping your bike from a height—EPS would cushion the fall by sacrificing itself, often showing visible cracks or dents after a significant impact. This single-use design is why helmets should be replaced after a crash.
While EPS excels at handling straight-on impacts, it has a critical weakness: rotational forces. These occur when your head strikes the ground or an object at an angle, causing rapid twisting. Picture a fall where your shoulder hits first, then your head whips sideways—EPS alone doesn’t effectively mitigate the brain’s rotation within the skull. Studies show this twisting can strain brain tissue, increasing the risk of concussions or diffuse axonal injuries. As cycling accidents often involve such angled impacts, EPS’s limitations highlight the need for additional protection.
MIPS, or Multi-directional Impact Protection System, isn’t a material like EPS—it’s a technology designed to address rotational forces. Developed in the 1990s by a Swedish neurosurgeon and engineer, MIPS emerged from years of research into brain injuries in sports. Their goal? To create a helmet feature that mimics the brain’s natural protective layer—the cerebrospinal fluid—allowing slight movement to reduce harmful twisting. Today, MIPS is a hallmark of advanced safety in helmets from brands like Bell, Giro, and Specialized, widely available through cycling helmets wholesale suppliers.
Inside a MIPS-equipped helmet, a thin, low-friction layer sits between the EPS foam and the inner padding. This layer, often a flexible plastic sheet, is anchored with small elastomers or connectors, allowing it to move independently of the helmet’s outer shell. During an angled impact, the MIPS layer slides 10 to 15 millimeters relative to your head, redirecting rotational energy away from your brain. This small movement—barely noticeable in daily use—can significantly reduce the strain that leads to concussions, making MIPS a game-changer in helmet design.
MIPS tackles a gap that EPS can’t fill alone. By adding this layer, helmets gain a dual-purpose defense: EPS absorbs linear impacts, while MIPS handles rotational forces. This innovation has made MIPS a sought-after feature in custom cycling helmets, appealing to riders who prioritize cutting-edge safety without sacrificing comfort or style.

MIPS doesn’t replace EPS—it builds on it. Every MIPS helmet still uses EPS as its primary impact-absorbing material, with the MIPS layer adding an extra dimension of safety. This partnership makes MIPS helmets a premium offering from cycling helmets suppliers, combining the best of both worlds.

In a MIPS helmet, EPS and MIPS work in tandem. The EPS foam absorbs the initial shock of a crash, compressing to protect against linear forces. Simultaneously, the MIPS layer activates during angled impacts, sliding to reduce rotational motion. This synergy ensures comprehensive protection, addressing both types of forces cyclists commonly face.
Consider a crash: you’re riding downhill, hit a rock, and tumble, striking the ground at an angle. In an EPS-only helmet, the foam would cushion the direct blow, but your brain might still twist inside your skull, risking injury. With MIPS, the helmet shifts slightly upon impact, cutting rotational force by up to 40% (per Swedish Royal Institute of Technology studies). This dual action makes MIPS helmets a top pick for custom biker helmets.
Research supports MIPS’s value. A study from the Swedish Royal Institute of Technology found that MIPS helmets reduced rotational acceleration by up to 40% in certain angled-impact tests. Another, in the Journal of Biomechanics, showed a lower concussion risk with MIPS. These findings align with the technology’s design to mimic the brain’s natural defenses.
Cyclists who’ve crashed with MIPS helmets often report milder outcomes—fewer headaches, less disorientation—compared to past incidents with EPS-only models. While anecdotal, this feedback underscores MIPS’s real-world impact.
MIPS helmets meet the same rigorous standards as EPS helmets, like CPSC (U.S.) and EN1078 (Europe), ensuring they match linear protection while excelling in rotational safety.
MIPS helmets cost $20-$50 more than EPS-only versions. For frequent riders—mountain bikers on rugged trails or commuters in traffic—the added brain protection justifies the price. Even casual riders may find the investment worthwhile for peace of mind.
A well-fitting EPS helmet still offers solid linear protection. However, if it’s old, damaged, or you ride in high-risk conditions, upgrading to a MIPS model from a cycling helmets manufacturer adds a safety edge. Helmets should be replaced every 3-5 years or after a crash anyway—why not go for MIPS?
The MIPS layer adds 25-50 grams—about the weight of a small apple—rarely noticeable to riders. Comfort isn’t compromised; the layer integrates smoothly into designs from bike helmets factories, maintaining padding and fit quality.
l Fit is King: Measure your head (54-62cm) and try helmets for a snug, forehead-covering fit. Adjustable dials or straps enhance comfort.
l Verify MIPS: Look for the yellow MIPS logo or check product specs.

When it comes to helmet safety, EPS is the foundation, absorbing linear impacts, while MIPS elevates protection by tackling rotational forces. Together, they form a dynamic duo, offering cyclists a robust shield against common crash injuries. Whether you’re sourcing from a bike helmets factory, a cycling helmets supplier, or a specialty retailer, choosing a helmet with both EPS and MIPS ensures you’re equipped with the latest in safety tech. Your brain is priceless—invest in a helmet that reflects that value and ride with confidence.
