Choosing a bike helmet: how to find the right one for cycling, skating and more

Buying a bike helmet seems simple, until you have to choose between an adult bike helmet, a children’s helmet, a MIPS model, a helmet with an LED light or a design with a visor. Marketing often focuses on one standout feature, but getting the right fit and choosing a helmet suited to how you’ll use it are just as important.

The most common buying mistakes come down to three pitfalls:

  • Choosing the wrong size: a helmet that wobbles or feels too tight won’t protect you as intended and often ends up unused.
  • Mistaking a safety standard for universal protection: a helmet for cycling and skating isn’t automatically suitable for motorcycling, skiing or demanding downhill rides.
  • Overestimating extra features: LED lights can help you be seen, but they don’t replace proper bike lights. A visor protects you from sun, wind and rain, but doesn’t make a bike helmet suitable for motorcycling.

So start with the activity, your head circumference and the relevant safety standard. Then consider comfort and extra features.

What to look for when buying a bike helmet

1. Measure your head and check the fit

Use a flexible tape measure around your head, about one to two centimetres above your eyebrows. Keep the tape level and note the measurement in centimetres. Compare it with the product’s size chart; a size M isn’t the same for every brand.

An adjustable helmet often has a dial at the back and adjustable chin straps. It should:

  • sit level and straight on your head;
  • not slide forwards or backwards;
  • not pinch at your temples;
  • stay firmly in place when you gently shake your head;
  • have a securely fastened chin strap, with no loose ends.

There’s limited room for growth when choosing a children’s bike helmet. Don’t buy one that’s clearly too large in the hope your child will grow into it. Check the fit regularly, especially after a growth spurt or a change in hairstyle.

2. Choose a helmet suited to the activity

A bike helmet for city rides, a mountain bike helmet and a BMX helmet don’t always have the same construction or coverage. EN 1078 is a common standard for inline skating, skateboarding and cycling. For example, the ACTION PW-905 product information states that the model has been tested to EN1078 and is CE-certified.

A skateboard helmet or inline skating helmet may be suitable for several recreational activities, but always check the stated intended use. A ski helmet is designed for winter sports; the OutdoorMaster Diamond II lists ASTM F2040 and CE EN 1077. These are different standards from those for a bike helmet.

For a motorbike or scooter, you need a separate ECE 22.06 motorcycle helmet. The MY 935 and MY 936 are listed in the product information as ECE R 22.06 models. Don’t use a bike helmet on motorised vehicles.

3. Consider the materials, comfort and extra features carefully

Many models combine an outer shell made from polycarbonate (PC) or ABS with an inner layer of EPS foam. EPS is designed to absorb impact energy. A lightweight helmet can be comfortable for commuting, but weight alone doesn’t tell you whether it’s suitable for your activity.

Also look out for:

  • Ventilation: multiple vents can improve airflow on warm rides.
  • MIPS: according to the product description, the MIPS system is designed to reduce harmful rotational forces in certain impacts. It doesn’t guarantee protection against injury.
  • LED light: a bike helmet with an LED light can help you be seen from behind. Check the battery life and whether the light is rechargeable.
  • Visor: a bike helmet with a visor can be useful for protection from sun, wind, rain and flying dirt. A removable visor is practical if you switch between city rides and sportier cycling.
  • Removable lining: a washable lining makes maintenance easier and helps keep the helmet comfortable over time.

Replace a helmet after a serious impact, even if there’s no visible damage. Also check the shell, fastening, straps and lining regularly for signs of wear.

Frequently asked questions about bike helmets

How tight should a bike helmet fit?

A bike helmet should fit snugly without creating pressure points. Adjust the rear dial first, then the chin straps. The helmet shouldn’t move when you gently turn your head from side to side. The chin strap should be fastened, but shouldn’t dig into your skin.

How long does a bike helmet last?

There’s no universal replacement date for every helmet. Replace yours immediately after a serious impact or if the shell, straps, fastening or lining is damaged. Materials can wear over time with normal use, so check the condition regularly and follow the manufacturer’s care instructions.

Is a bike helmet with an LED light enough for cycling in the dark?

No. An LED light on your helmet can help you be seen, but also check that you have the legally required bike lights, reflectors and visible clothing. Charge a rechargeable light in good time and check that it’s securely attached before you set off.
