Best Mountain Bike Helmet Under $100


Helmets are an essential biking accessory in terms of form and function. They always keep us safe in the event of a crash but must remain comfortable in all other facets of wear. They can be pricey but, for those on a budget, it doesn’t mean there aren’t plenty of choices when picking the best mountain bike helmet under $100.

When designing the best mountain bike helmet under $100, the challenge is reconciling the need to conform to the latest safety standards without lacking ventilation or looking too odd. Beyond the safety rating, fit, ventilation and style are vital aspects that influence helmet selection. A safe but uncomfortable helmet or one that isn’t stylish enough will not appeal to buy it as safety equipment.

Slip-layer liners have been a significant breakthrough in modern mountain bike helmet design. As the technology has popularized, it has also scaled and reduced cost and can now be found on several budget lids. Read on to find your best mountain bike helmet under $100, from our list below. 

Best Mountain Bike Helmet Under $100 – Best Options

#1 – 1 – GROTTICO Bike Helmet

The GROTTICO Bike Helmet has done a splendid job by adding all the necessary improvements in its latest mountain bike helmet, thus making it compatible with men and women. It features a rather sophisticated design for both sexes and keeps the rider’s head safe from unwanted injuries and crashes.

Our top-best mountain bike helmet is under $100 due to its many certifications by the CPSC, E.U., and U.S. cycling standards. It’s completely safe to wear it while on a journey to cruise uphill and downhill terrains. An adjustable dial fitting system is something worthy within the helmet.

Using the dial fit system, users can adjust the fit according to their comfort and convenience. In-mold construction of durable polycarbonate shell with EPS foam liner reduces the weight with no compromise on the protection of the riders. You’d also love the presence of back LED light present in this bike helmet. It comes with three lighting modes, is USB rechargeable, and makes a rider visible at night.

#2 – Giro Fixture MIPS Cycling Helmet

Giro is a reputable brand for producing mountain bike helmets that help keep riders safe from serious crashes. The Giro Fixture MIPS Cycling Helmet model from this brand has caught the eye of many bikers who want to get the best option available in an affordable range.

Featuring an open-face design, Fixture MIPS is light in weight, has a durable construction, and is comfortable enough to help bikers cruise their way through rough trails. To begin with, the outer shell of the helmet features in-mold polycarbonate construction. Combined with that is an EPS liner on the inside to keep the biker’s head comfy enough.

Next, bikers can also enjoy the helmet’s integrated MIPS (Multi-Directional Impact Protection System). This technology can keep a biker’s head from severe traumas, including concussions and internal bleeding. Not to forget, the bike helmet comes with 18 wind tunnel vents to maintain the airflow on the inside. No matter how long you keep wearing it, Fixture MIPS isn’t going to disturb you with sweat or extra moisture.

Other additions like the Roc Lock Fit system, universal adjustability, plush padding for immense comfort, and a removable visor make this mountain bike helmet a top priority for bikers who are short on the budget.

  • Integrated MIPS technology
  • EPS liner with extra inner comfort
  • Durable polycarbonate shell
  • Quick and easy adjustment.


  • Hard to clean
  • Not scratch resistant

#3 – POC Tectal Race Spin Helmet

The POC Tectal Race Spin Helmet uses a standard plastic buckle to latch the chin strap. For the price point, we would not have minded the magnetic Fidlock system featured on many of the high-end mountain bike helmets, but old school users might prefer the old school solution.

Otherwise, the straps are outstanding, providing a large Y shape that is adjustable in nearly every direction allowing you to better dial in the fit. The visor is adjustable but requires adjusting a screw that locks it in place. This makes adjusting on the fly a pain and keeps it locked in once you want it. We prefer the more dynamic system featured on helmets like the Bell Sixer.

Like most helmets in this price range marketed at the trail and all-mountain riders, the POC Tectal Race Spin Helmet also includes a goggle strap. Finally, the Tectal Race Spin is outfitted with a RECCO chip used in search and rescue situations.
