To help protect you and the kids while cycling off-road, we've put together a guide to the best mountain bike helmets for adults and children.

Mountain bike helmets for adults

Giro Manifest Spherical

This half-shell helmet has a sleek design and comfortably fits an array of head sizes and shapes. The large front-to-back vents provide fantastic airflow, and when you work up a sweat, the interior padding does a good job of absorbing it.

Giro Chronicle MIPS

This one might have a lower price tag than other Giro helmets, but it performs just as well. In addition to being excellent value, it has a truly versatile fit, working well as either a women’s or men’s mountain bike helmet. It also sits low on the head, making it feel secure while protecting all vulnerable areas.

Bell 4Forty MIPS

Another affordable helmet, this model has a MIPS liner, which adds more protection against the force of impact at different angles. A lot of major brands use this technology for their helmets, and it’s often marked by a little yellow logo.

Smith Venture MIPS MTB

Easy to adjust, this helmet’s VaporFit system ensures that it fits well and is super comfortable. Plus, the anti-bacterial performance lining keeps it smelling fresh, no matter many hill climbs you have to tackle. The integrated visor is really handy for stopping raindrops or sunlight from getting in your eyes.

Troy Lee Adult All Mountain A2 Bike Helmet

Style-conscious mountain bikers will love how this helmet looks. Available in a variety of colours, including a chic turquoise or bold green, it’s not only pretty but practical too. It offers fantastic ventilation while fitting snugly to the head, so it won’t wobble about however bumpy your route is.

Giro Montara MIPS Women’s Mountain Cycling Helmet

This women’s mountain bike helmet is compact and comfortable. It weighs next to nothing without compromising on protection and has easy go-pro attachments so you can record a video while you cycle. And the moisture-wicking pads are great for absorbing sweat.

Endura MT500

This helmet has so many features, it feels like it’s just showing off. The peak is adjustable and lifts up far enough so you can store cycling goggles, while it also has a clip-off accessory mount for a headlight or helmet cam. Lightweight and well-ventilated, it’s on the pricier side, but you get a lot for your money.

Kids will feel like mountain biking pros when wearing this helmet. The stylish shape looks cool while offering great protection. And with a whopping 17 air vents, it’ll stop your child from getting too hot and bothered on long bike rides.

This Giro model is one of the best mountain bike cycle helmets for older children. It’s really comfortable and lightweight, so you shouldn’t have any issues with encouraging them to wear it. The adjustable dial at the back can be used to fit your child as they grow.

Bell Spark Jr

Bright red and with a racing stripe on the side, children will love the look of this helmet. The many ventilation holes keep the head cool, and the shell has space for them to grow.

This helmet has a built-in LED to aid visibility when the light starts to fade on your bike ride. Durable and safe, the strap buckles are also anti-pinch, so they won’t hurt little ones when putting the helmet on.
