5 Best Convertible Mountain Bike Helmets (March, 2023)

Updated on June 2, 2022

Full-face helmets with removable chin guards are available in convertible mountain bike helmets, which may be removed and reattached.

A convertible mountain bike helmet is essentially a full- and open-face helmet all in one piece.

As a result, open-face and full-face helmets are more versatile than traditional helmets, which are more rigid.

How Do Mountain Bike Helmets Work?

There are two layers of EPS foam sandwiched between the polycarbonate helmet shell and the liner.

The strong plastic shell protects the eps foam, allowing the helmet to flow along the ground instead of catching and whipping your neck around.

It’s also worth noting that eps foam will shatter or crush and absorb some force in the event of a hard hit.

Helmets shield your brain from the effects of the outer world by cushioning the shock.

Are Convertible Mountain Bike Helmets Safe?

Mountain bike helmets, especially those that convert to a headgear form, are quite safe.

This is because, depending on your needs, a full-face helmet can be substituted.

It is best to wear a helmet with a full-face shield to protect yourself.

In addition to protecting your skull, it also shields your face and jaw in the event of an accident.

  • Ventilation: 23 Vents
  • Weight: 1.73 lbs.
  • Other Specs: Adjustable Visor System

Wearing this helmet for long periods of time is made easier because to its lightweight construction.

My favourite feature was the helmet’s airflow across the top of my head.

Vents on the top of the helmet allow air to flow in and keep you cool while you’re riding.

Increased comfort and reduced stuffiness are achieved with this method.

BELL Super 3R MIPS Helmet is my first choice for a convertible MTB helmet.

By far, the Bell Super 3R MIPS is the best MTB helmet I’ve ever tried.

As well as numerous other benefits, I greatly love the helmet’s built-in camera mount feature.

Using this camera mount, you may capture your MTB adventures on film.

When you attach a GoPro camera to the device, you’ll be able to record every second of your voyage.

The breakaway function of this helmet’s mount makes it even more secure.

During a high-speed accident, this mount breaks apart from the helmet in order to minimise the danger of injury.

This helmet exceeded my expectations for protection in every aspect.

In the event of an accident, the MIPS technology in this attachment will shield you from potentially hazardous spinning forces.

You may also change the fit of this helmet to your head’s precise dimensions so that it will fit you perfectly.

You may even utilise your goggles while wearing this helmet thanks to the adjustable visor.

The ‘Wind Tunnel’ ventilation system of this helmet has peaked my curiosity.

The outcome is a pleasant and peaceful ride.

My attention was drawn to the helmet’s hydrophilic padding.

My interest was piqued by the helmet’s hydrophilic cushioning.

This padding is capable of soaking up a lot of water.

This helmet can speed up the drying process if you’re prone to excessive perspiration while riding.

As a result, you won’t get tingling eyes from sweat during long MTB rides.

The X-static lining in this helmet also helps to reduce odours and keeps your helmet smelling fresh even after prolonged use.

In addition to its high level of safety, this helmet has impressed me because of its MIPS technology, which reduces dangerous rotational forces on the wearer.

In addition, the helmet’s polycarbonate shell is exceptionally resistant to wear and tear.

Despite this, the foam layer on the inside of the Giro Switchblade shows that it can withstand quite a deal of harm before it fractures or injures the user.

With the Air-DH Fit system, you can customise the helmet’s fit to your head perfectly.

What I Like?

  • A visor that can be telescopically shifted.
  • A huge visor with a camera attached to it.
  • The airflow is spectacular.
  • Additional advantages include the opportunity to tailor the fit.
  • Sturdy

What I Don’t Like?

  • The visor is weak at best.
  • Quite hefty, according to some
  • The chin bar is difficult to put on because of its shape.

If you’re on a tight budget but still want a high-quality helmet, the Demon United convertible mountain bike helmet is an excellent choice.

For the price, this is one of the best convertible helmets on the market.

After wearing it for a few hours, you won’t get tired of it because of its lightness.

In addition, the helmet’s strategically positioned air vents ensure adequate ventilation.

As a result, your trip won’t be as oppressively hot.

The helmet’s chin-bar was incredibly easy to remove and reinstall.

In order to attach or remove the chin bar on many other convertible helmets, you must first remove the chin bar from the helmet.

The face bar is held in place by a simple click mechanism on this one.

Allows you to fine-tune helmet fit to your individual head size via cinch-tight back dial.

The visor on this helmet can be changed as well.

As long as the visor isn’t raised, resting your goggles there isn’t necessary.

Thanks to the polycarbonate outside and the cushioning inside that absorbs shock, I was completely impressed with this helmet.

Combined with the well-built chin bar, this guarantees your protection in the event of an accident.

What I Like?

  • Affordable
  • Lightweight
  • Great airflow

Improves the user’s degree of comfort and reduces wear and tear on the equipment.

You’ll stay cool even on hot days because to the many air vents in this helmet.

Additionally, this helmet’s padding features a unique sweat-guiding design.

The sweat guide design directs moisture away from your eyes, keeping them dry.

Additional benefits include lessening sweat-induced odour with the x-static cushioning.

Consequently, wearing it for extended periods of time is enjoyable.

The fit of this helmet is unexpected.

You can achieve this thanks to the helmet’s float fit technology, which allows you to fine-tune the fit to your own head size.

The safety features of this helmet far exceeded my expectations.

In terms of safety, the spherical MIPS technology used in this helmet outperforms the standard MIPS.

When struck, it is able to withstand a lot of force because of its successive layering mechanism.

In addition, a camera attachment with a detachable mechanism is built within the helmet.

As a result, you may not only keep track of your travels, but also do it in a manner that is both convenient and secure.

This is because the mount separates from the wearer in high-impact scenarios to minimise harm.

An important feature of this helmet is the high level of protection that it provides.

Any rotational forces you might feel during a collision are protected by Flex Spherical MIPS technology in this helmet.

Strength and rigidity are provided by the helmet’s fusion in moulding process, which involves fusing the outside polycarbonate shell with the inner EPS foam liner.

As a result, the helmet’s progressive EPS foam layers are able to absorb shocks quite effectively.

This helmet is also very easy to put on and take off.

In order to keep your head cool while riding, the helmet, visor, and chin-bar all contain strategically positioned air vents.

The padding on the helmet is designed to move away from your face in order to protect your eyes and spectacles.

With an X-Static foam liner, the helmet stays fresh and smells great!

The cushioning is made of quick-drying materials to save drying time after washing.

In addition, the helmet’s fit is outstanding.

Helmets can be moved in reaction to an impact without the wearer having to move their head.

Wearers of MIPS-equipped helmets are protected against the dangerous rotational forces that may be generated as a result of an angled hit.
