Cómo elegir el casco adecuado para la bicicleta eléctrica: la seguridad es lo primero

Choosing the right e-bike helmet is an important part of preparing for electric bike riding. With e-bikes making longer journeys and higher-speed commuting more accessible, it's worth understanding what separates one helmet from another.

From safety certifications and materials to visibility, comfort, and smart features, there are several factors to consider before making a decision.

The right e-bike helmet should suit your bike, your riding speed, and the conditions you encounter regularly.

As e-bikes become more popular for urban commuting and recreational cycling, they're making cycling accessible to more people. Pedal assistance makes it easier to travel longer distances, tackle hills, and maintain speeds that would otherwise require considerably more effort.

But these advantages also change what riders should consider when choosing their equipment.

An electric bike can reach higher speeds with less physical effort, and riders may find themselves sharing busy roads with cars, buses, and motorcycles. The type of e-bike, the speed at which it operates, and the environment in which it's used all influence what you should look for in a helmet.

Not every e-bike is the same. Some provide assistance up to 20 mph, while Class 3 e-bikes in the United States can assist riders up to 28 mph. In Europe, speed pedelecs can provide assistance up to 45 km/h.

That doesn't mean every rider needs exactly the same helmet. It means understanding how helmets are designed and tested becomes more important when choosing one for your regular rides.

When choosing an e-bike helmet, there are several key factors to consider: materials and build quality, safety certifications, additional safety features, and comfort and fit.

A helmet's appearance or price alone cannot tell you how it will perform. Understanding these different elements helps you make a more informed decision.

Have you ever considered what materials are used to protect your head, or whether different helmet constructions make a difference?

Most cycling helmets combine a hard outer shell with an impact-absorbing inner liner. The outer shell helps distribute forces and protects the liner from everyday wear, while the inner material is designed to manage energy during an impact.

Common outer shell materials include ABS and polycarbonate (PC). ABS shells are often thicker and heavier, while polycarbonate is frequently used in lighter helmet constructions. Neither material automatically makes a helmet safer, because the complete design and how it performs in testing matter more than the shell material alone.

Build quality is another consideration. Look at how the different parts of the helmet fit together, whether the straps and buckle feel secure, and whether the adjustment system operates smoothly.

A well-made e-bike helmet should also withstand normal daily handling without its components becoming loose or uncomfortable. Check the manufacturer's instructions for cleaning and maintenance, particularly if the helmet includes electronic components.

When choosing an e-bike helmet, safety certification is one of the most useful places to start.

Certifications indicate that a helmet has been tested against specific requirements. However, different standards were developed for different types of riding, so it's important to understand what each one means.

In the United States, bicycle helmets are generally required to comply with the CPSC bicycle helmet standard. In Europe, EN 1078 is a recognized standard for bicycle helmets.

These standards establish requirements for areas such as impact performance, retention systems, and helmet construction.

They provide an important safety baseline, but they should not be interpreted as guaranteeing protection at a particular riding speed.

What happens when you ride a faster e-bike, such as a speed pedelec capable of providing assistance up to 45 km/h?

NTA 8776 was developed specifically for speed pedelec helmets. Compared with conventional bicycle helmet standards, it includes requirements addressing higher impact test velocities and additional coverage, particularly around the temples and back of the head.

This makes NTA 8776 worth considering for riders using faster e-bikes, especially those regularly sharing roads with motor vehicles.

It's important to understand that certification test speeds are not the same as the speed of a bicycle during an accident. NTA 8776 does not guarantee protection in every crash at 45 km/h, but it provides a relevant additional standard for comparing helmets intended for faster cycling.

You've probably noticed the small yellow Mips logo on some bicycle helmets.

Mips stands for Multi-directional Impact Protection System. It is designed to help manage rotational motion that can occur during certain angled impacts.

Some Mips systems use a low-friction layer that allows limited movement between the helmet and the head. This movement is intended to help reduce rotational forces transferred to the head in certain crash scenarios.

Mips is not a replacement for safety certification, and its presence alone doesn't determine whether one helmet is safer than another. It is an additional technology to consider alongside fit, helmet construction, and independent testing.

AURA isn't the only UNIT 1 helmet evaluated by Virginia Tech. The NEON Smart Helmet has also received a 5-star rating, offering riders another option when comparing independently tested smart helmets.

When comparing helmets, look at the actual test results rather than assuming that a higher price or a longer feature list automatically means better protection.

Helmets are primarily designed to help protect your head during an impact. But some modern e-bike helmets also include technology intended to support riders before and after an accident.

At UNIT 1, we call this approach Active Safety. It brings together impact protection, visibility, and connected functions rather than treating helmet safety as something that matters only when a crash occurs.

Visibility becomes particularly relevant when commuting through traffic, riding at intersections, or traveling early in the morning or after dark.

Traditional bicycle helmets may use reflective details or bright colors, while smart helmets can incorporate lighting directly into their design.

Integrated lights can help make a rider more noticeable without relying entirely on separate accessories. Some systems also include turn signals and automatic brake lights, which communicate a rider's intentions to people nearby.

UNIT 1 helmets such as AURA support integrated lighting, while compatible models can connect with the UNIT 1 Remote to enable turn signals and automatic brake lights.

These features complement normal signaling and appropriate bicycle lighting rather than replacing them.

Another consideration is what happens if a rider is injured or unable to contact someone after an accident.

Some smart helmets include Crash Alert technology that can detect a possible crash and begin a countdown. If the rider doesn't respond, the system can notify a selected emergency contact and share the rider's location.

This can be particularly relevant for people who regularly ride alone or travel longer distances.

Crash Alert is an additional support feature, not a substitute for emergency services, and its operation depends on the requirements of the connected system.

When comparing smart helmets, check what connectivity is required and how the emergency notification process works.

Even a helmet with excellent specifications needs to fit correctly.

An e-bike helmet should sit level on your head, remain stable when you move, and feel secure without creating uncomfortable pressure.

Start by measuring your head circumference and comparing it with the manufacturer's sizing chart. Don't assume that the size you wear in one brand will automatically fit the same way in another.

Look for a helmet with an adjustment system that allows you to fine-tune the fit. The straps should sit comfortably around your ears, and the chin strap should be secure without restricting normal movement.

Helmets also come in different shapes, so it's worth considering how the internal padding and retention system feel against your head.

E-bike riders often cover longer distances than they would on a conventional bicycle, which makes comfort especially important.

Ventilation helps manage heat, particularly during warmer weather, while helmet weight and padding can affect how comfortable the helmet feels after extended use.

A helmet that feels comfortable during a quick fitting may feel different after a longer commute. Consider the typical duration of your rides and whether you regularly wear glasses or other compatible accessories.

Comfort should never come at the expense of a secure fit, but finding the right balance can make it easier to wear your helmet consistently.

Not every electric bike rider has the same needs. Before choosing a helmet, think about your typical routes and riding conditions.

These considerations help narrow your options without assuming that one helmet will be the best choice for every rider.

Choosing the right helmet also means knowing when the one you already own may need replacing.

A helmet should be replaced after a significant impact, even if the outer shell appears relatively undamaged. The internal impact-absorbing material may have been affected in ways that aren't visible.

You should also inspect your helmet regularly for damage to the shell, straps, buckle, and adjustment system.

Follow the manufacturer's replacement and maintenance guidance, especially for helmets with integrated electronics. If your helmet no longer fits securely or its components are damaged, it's time to consider a replacement.
