Bicycle Helmets

Bike Helmets

A well-fitting bike helmet should match your riding style and head shape. Start with the type of cycling you do. Then compare bike helmet size, coverage, ventilation and adjustment. Features such as a visor or rear light can improve comfort or visibility but correct fit remains the priority.
 

Which bike helmet is right for you?

City and e bike helmets

A city bike helmet suits commuting and everyday journeys. These helmets often balance ventilation with practical coverage. Some models have a removable visor or integrated rear light.
An e bike helmet may offer more coverage around the back and sides of the head. Some are designed for specific e-bike speed categories. Check the helmet specification and intended use before ordering. Browse city bike helmets and e bike helmets when you mainly ride in traffic or use an electric bicycle.
 

Road and gravel helmets

A road bike helmet is usually lightweight and well ventilated. Its shape is designed for a forward riding position. View road bike helmets when speed, low weight and airflow are important.
A gravel helmet combines road-style ventilation with practical features for mixed surfaces. Some models have a small visor or additional rear coverage. Choose one that remains comfortable during longer rides.
 

MTB, BMX and full face helmets

An MTB helmet normally covers more of the back of the head than a road model. Many MTB bicycle helmets include an adjustable visor. This helps shield your eyes from sunlight, mud and branches.
A full face bike helmet also protects the chin and face area. Full face helmets are intended for disciplines such as downhill and enduro riding. Check ventilation, weight and the manufacturer’s stated discipline.
A BMX helmet often has a rounded shell with fewer ventilation openings. BMX bicycle helmets suit BMX riding, skate parks and similar use. Do not choose a helmet only by its appearance. Check that it is approved for cycling and suitable for the intended discipline.
 

Children’s bike helmets

A kids bike helmet must fit the child now. Do not buy a large size for the child to grow into. A loose helmet can move out of position.
Measure the child’s head and compare it with the adjustment range. Children’s bicycle helmets are available for small children and older junior riders. A children’s bike helmet may include an insect net, simple buckle or rear light. Adult models should only be considered when the measured size and shape provide a secure fit.
 

How to choose the correct helmet size

How do you measure your head for the correct size? Place a flexible tape around the widest part of your head. Run it about two centimetres above your eyebrows and just above your ears. Keep the tape level and record the measurement in centimetres.
Compare this number with the manufacturer’s bicycle helmet sizing chart. Size labels can differ between brands. A medium helmet from one brand may have a different adjustment range from another.
Choose the size that contains your measurement without relying on the very end of the adjustment range. Try the next size when your measurement sits exactly between two sizes. Head shape also matters. The helmet should feel evenly secure without creating painful pressure points.
 

Check fit, straps and head coverage

A correctly fitted bike helmet should sit level on the head. The front edge should rest around one or two finger widths above the eyebrows. It should not tilt backwards or cover your vision.
Tighten the rear adjustment dial until the helmet feels secure. It should remain in place when you gently shake your head. Do not tighten it so far that it becomes uncomfortable.
The side straps should form a V-shape below each ear. Fasten the chin strap and leave enough room for one or two fingers. The buckle should not rest directly against the throat.
An adult bike helmet should provide the coverage required for its intended discipline. More coverage can be useful for trail and urban riding. It can also add weight or reduce airflow.
 

Ventilation, visor, lighting and useful features

More ventilation helps release heat during road rides and warm-weather cycling. Fewer or smaller vents can suit short city rides and colder conditions. Internal channels can guide air through the helmet.
A bike helmet with visor can reduce glare and shield your eyes from rain or loose dirt. A peak-style visor is common on MTB models. Some urban helmets use a transparent eye visor. Check whether it is removable or replaceable.
A bike helmet with light can improve your visibility from behind. Integrated lighting does not replace the lights required on the bicycle. Check whether the light is rechargeable and whether replacement units are available. Separate bicycle helmet lights must only be fitted to approved mounting points. Do not drill into the shell.
Other useful features include insect nets, washable padding and ponytail-compatible adjustment systems. Verify every feature in the product specification.
 

MIPS and other protection technologies

A MIPS bike helmet contains a system designed to help reduce rotational motion transferred to the head during certain angled impacts. Other manufacturers use different rotational protection systems. No system can prevent every injury or guarantee protection.
Fit and intended use remain essential. Compare the complete helmet rather than choosing only by a technology name. ABUS bicycle helmets and other brand ranges include different shapes, features and protection systems.
 

When should you replace a bike helmet?

Replace a bicycle helmet after a significant impact even when the damage is not easy to see. The internal impact-absorbing material may have compressed.
Also, replace it when the shell is cracked or the straps and buckle are damaged. Deep dents and loose internal parts are warning signs. Follow the replacement interval and care guidance supplied by the manufacturer. Do not use strong solvents or leave cycling helmets in excessive heat.
 

Frequently asked questions about bike helmets

What is the difference between road, MTB, city and full face helmets?
Road cycle helmets focus on low weight and ventilation. MTB models usually add rear coverage and a visor. City models offer practical features for everyday riding. Full-face models include chin and facial coverage for demanding off-road disciplines.

Are visors, rear lights or extra coverage useful?
A visor helps with glare and loose dirt. A rear light can improve visibility. Extra coverage may suit urban or off-road use. Choose these features only after confirming size, comfort and intended use.

What does MIPS mean?
MIPS is a helmet system intended to help manage rotational motion during certain angled impacts. It does not make a helmet injury-proof. The helmet must still fit correctly and suit your cycling discipline.

When should a bike helmet be replaced?
Replace it after a significant impact or when you find cracks, dents or damaged straps. Follow the helmet manufacturer’s guidance for age-related replacement.

Are bike helmets compulsory in the UK?
For standard cycling in Great Britain there is no general legal requirement to wear a helmet. Highway Code Rule 59 says cyclists should wear a correctly sized helmet that conforms to current regulations and is securely fastened. Check the current rules for cyclists and any separate requirements for organised events or specialist vehicles.
