If you're searching for the ultimate mountain bike helmet, you're making a smart and safe choice! A high-quality bike helmet is crucial for protecting your head from impact while taking on rugged trails. Whether you want a full face helmet for aggressive downhill and enduro riding or a breathable open face helmet for trail adventures, choosing the right MTB helmet will boost both your safety and your riding performance.
At BikesOnline, we offer a leading range of open face helmets and full face MTB helmets made with advanced materials like polycarbonate and carbon fibre for maximum protection. Every helmet is designed for comfort and ventilation—ideal for long mountain bike rides.
Choosing between an open face MTB helmet and a full face helmet comes down to your riding style and safety needs.
Open face mountain bike helmets (also called half-shell helmets) offer excellent ventilation and all-day comfort for trail and cross-country riders. These MTB helmets often have extended rear coverage, providing more protection while staying lightweight and breathable.
Pros:
Cons:
If you value comfort and airflow for everyday trail riding, an open face MTB helmet is your best bet.
For aggressive riders tackling steep descents, jumps, or technical terrain, a full face helmet offers unbeatable protection. These helmets cover the entire head, chin, and face, making them the top choice for downhill and enduro.
Pros:
Cons:
For big descents and bike park riding, a full face MTB helmet is the safest option.
At BikesOnline, you’ll find an extensive selection of mountain bike helmets, including both open face and full face options at competitive prices. Take advantage of direct-to-consumer pricing, fast Australia-wide shipping, easy instalment plans, and expert support to find your ideal bike helmet.
Are open face helmets safe for mountain biking?
Yes! Open face MTB helmets are ideal for trail and XC riders, offering coverage and ventilation. For downhill or enduro, choose a full face helmet.
What’s the difference between open face and full face MTB helmets?
Open face helmets protect the top, sides, and back of your head—full face helmets add a chin bar for all-around impact protection.
Can I use an open face helmet for enduro riding?
Light enduro is fine, but technical descents call for a convertible or full face helmet for maximum safety.
How do I choose the right MTB helmet size?
Measure your head circumference and use our size guide—your mountain bike helmet should be snug but not tight.
Do open face MTB helmets come with visors?
Yes, most open face MTB helmets include adjustable or removable visors for sun and debris protection.
Mountain bikes are available in multiple different styles to take on any style of trail you choose.
