How to buy a helmet: choosing the right model for cycling, skating, scooter or motorbike

Buying a helmet might seem straightforward – until you start comparing different sizes, safety certifications and models side by side. A cycling helmet isn’t automatically suitable for BMX, a skate helmet doesn’t offer the same coverage as a full-face helmet, and a child’s helmet needs to be adjusted differently to a motorbike helmet.

Marketing copy often focuses on eye-catching colours, ventilation openings or a visor. Yet it’s the intended use, the fit and the correct standard that really determine whether a helmet is right for you. These checkpoints will help you avoid a bad purchase.

Common pitfalls when buying a helmet

1. Choosing a universal size without measuring your head

An adjustable helmet can accommodate different head sizes, but an adjustment system won’t make a helmet that’s too big or too small fit properly. Measure the circumference with a flexible tape measure, about two centimetres above your eyebrows and horizontally around your head.

Then check the size chart for the specific model. A child’s helmet of 20–23 inches is not the same as a model of 54–58 cm. The unit of measurement also varies from product to product.

A well-fitting helmet:

  • sits horizontally and doesn’t tilt back;
  • doesn’t move when you shake your head;
  • encloses your head without pressure points;
  • has a chin strap that fastens securely without pinching.

2. Confusing a safety certification with protection for every sport

An EN1078 helmet is intended for activities including cycling, skateboarding and roller skating. That doesn’t make such a helmet suitable for motorbike riding. For motorbike and scooter use, you need to look for an appropriate ECE R22.06 helmet and check the information on the actual label and product page.

According to the product description, the ACTION PW-905 and PW-903 models are EN1078 tested and CE certified. For the MY 935 and MY 936 motorbike helmets, the product description states ECE R 22.06. These details come from the relevant product information; always check the marking, instruction manual and current regulations for your vehicle upon receipt.

3. Only looking at ventilation or a visor

Ventilation is pleasant during a bike ride or an intense mountain bike session, but more openings don’t in themselves say anything about the fit or safety standard. A visor can reduce sun, rain or flying debris, but it must not obstruct your view.

With a full-face helmet, you should also check that the chin bar is secure, that the fastening works properly and that the helmet is suitable for the activity. A model designed for downhill mountain biking isn’t automatically suitable for a motorbike.

The key specifications to compare

Material and construction

Many cycling and children’s helmets combine an outer shell of PC or PVC with an inner layer of EPS. With in-mould construction, the outer shell and foam are bonded together according to the product description. A skate helmet may use a different construction. Don’t just look at material names – also consider the application and safety standard.

A full-face helmet covers not only the head but also the chin and parts of the face. This can be suitable for BMX, downhill or dirt biking, but it’s generally heavier and warmer than a standard cycling helmet.

Fit, size range and fastening

A dial, adjustment strap or adjuster helps you fine-tune the helmet. Also check the chin strap. A quick-release buckle is practical for children; a D-ring system is found, for example, on certain mountain bike helmets.

Examples of stated size ranges:

  • RoyalBaby children’s helmet: 20–23 inches, intended for children aged 5–13 years;
  • DKONI HS-062: 54–58 cm in size M and 56–61 cm in size L;
  • MY 935: 53–64 cm, depending on the size selected;
  • MY 936: 54–62 cm, depending on the size selected.

These ranges are indications from the product information. The shape of the helmet and the shape of your head also play a role.

Care and replacement

Check a helmet before each use for cracks, loose parts and damaged straps. Wash removable liners with a mild detergent and let them air dry. Do not use solvents or harsh cleaning products.

After a significant impact, you must replace the helmet, even if there’s little visible damage on the outside. The product information for some models also recommends replacement after three to five years, as materials can degrade. Always follow the manufacturer’s instructions.

Frequently asked questions about buying a helmet

How do I know which helmet size I need?

Measure your head circumference with a flexible tape measure and compare the result with the size chart for the model. Adjust the helmet using the dial or straps. The helmet should sit horizontally and not shift when you move your head.

When should I replace a helmet?

Replace a helmet immediately after a significant impact or if you see cracks, deformation or loose parts. Some product descriptions also mention a service life of three to five years. Check the manufacturer’s instructions for this, and do not store a helmet for long periods in heat or direct sunlight.

Is a cycling helmet suitable for a scooter or motorbike?

Not as standard. A cycling helmet or skate helmet with EN1078 is intended for non-motorised activities. For a scooter or motorbike, you need a model that is designated for motorbike use, such as a modular helmet or full-face motorbike helmet with the appropriate ECE marking. Always check the current legal requirements and the label on the helmet.
