Top 15 Best Road Bike Helmet Under 100 Reviews 2021


Giro Women's Seyen MIPS Helmet, Matt Black Floral, S 51-55cm
  • 25 Wind Tunnel vents with internal channeling
  • In-Mold polycarbonate shell with EPS liner
  • Four-piece polycarbonate interlocking Hardbody shell
  • Featherweight webbing with Slimline buckle
  • Integrated MIPS technology

The first product we would like to review is the best road bike helmet under 100 for women. This brand said that this helmet was specifically designed only for women. The Giro Seyen is lightweight due to its polycarbonate material and has a fashionable look.


It also comes with MIPS - Multi-Directional Impact Protection System. This standard is often considered when evaluating the level of protection of a helmet. It means this helmet could give you a safe trip. Additionally, it has 25 active vents and exhaust channels to make your head always feels cool for a long ride.


However, although we love the specific design of this helmet for women, it has only one black option to choose from. With this backward, many women will not be satisfied.

PROS

  • Lightweight design
  • MIPS standard
  • Giro’s Wind Tunnel system

CONS

  • Only black version

BELL Unisex's Formula LED MIPS Road Helmet, Ghost Matte Black, Small/52-56 cm
  • Integrated MIPS (Multi-Directional Impact Protection System)
  • Fusion In-Mold polycarbonate shell - A process pioneered by Bell bonds the helmet's outer shell to the EPS foam liner to create a sturdier helmet.
  • Float Fit LED - A lightweight fit system with an easy-to-turn rubber overmolded dial for adjustments (integrated with MIPS)
  • No-Twist Tri-Glides: Quick-adjust fasteners that help keep straps flat and properly positioned
  • Sweat Guide pad design pulls moisture away from the brow pad and away from eyewear

Bell Formula is the best road bike helmet under 100 for fast ride. After spending an amount of time testing, we could say it is an excellent helmet of this brand. With the Bell Fusion In-Mold process, the manufacturer said that it could improve the helmet sturdier. Besides that, MIPS integrated is a bonus point that brings us an extraordinary helmet for our trip.


On the other hand, we highly appreciate its Float Fit LED system that not only makes you safe but also other people. We were also impressed by its design. It fits our head perfectly and like other Bell helmets, Bell Formula’s extended coverage down the back of the head helps us feel more secure and balanced.


It includes 10 vents that do a great job of giving you fresh air to make you cool over the head and the rear. This model is for both men and women. You could be a bit confused when buying this helmet because it is available in plenty of colors.


Unfortunately, it weighs 235g. It is medium weight in the range of road bike helmet under 100, but this could be a tiny inconvenience for normal users in long-distance rides.

PROS

  • Good protection
  • Good feeling
  • Plenty of colors

CONS

  • Medium weight

ABUS Viantor Road Bike Helmet - Sporty Bicycle Helmet for Beginners - for Men and Women - Blue, Size S
  • Multi-shell in-mould for long-lasting connection of multi-part outer shell and shock-absorbing helmet material (EPS)
  • Ponytail compatibility: helmet suitable for braid wearers
  • Good ventilation thanks to 4 air inlets and 14 air outlets connected by flow channels
  • Semi-enclosing plastic ring connected to adjustment system for optimum stability and form-fitting
  • ActiCage: Structure reinforcement integrated in the EPS to optimise stability

ABUS Viantor is the best road bike helmet under 100 for beginners. ABUS is a brand that comes from German. It provides many models from high to low segments. We say it because you could find many features in ABUS Viantor that only be found in their high-end products.


With the aim to create an ideal road bike helmet for beginners. ABUS Viantor utilizes the Structure-reinforced technique, shock-absorbing helmet material in combination with the multi-part outer shell that many brands are using on higher priced helmets. It will offer users high head safety, especially those who are a newbie.


Moreover, we really love its design. This model fits perfectly on our heads. In addition, thanks to its ponytail compatibility, it can be used for both men and women who have long hair as well.


This helmet also comes with 4 air inlets and 14 air outlets which keep your head throughout a long ride. If you feel confused when buying Bell Formula above due to its range of colors, we don’t want to imagine how would you feel when choosing this ABUS Viantor because it has over 10 color versions for you to choose from.


Although this helmet was developed for beginners, we do not appreciate that it doesn’t come with the MIPS standard which could be found on other road bike helmet under 100. This could make it less secure for users.

PROS

  • Good design
  • Comfortable experience
  • Color options

CONS

  • Lack of MIPS standard

Giro Nine Bicycle Helmet, Matte White, S | 51-55 cm
  • Mips; hard shell construction
  • Roc Loc 5 adjustment system
  • 32 wind tunnel ventilation openings
  • Weight: approx. 260 g
  • Sizes: S (51 - 55 cm), M (55 - 59 cm), L (59 - 63 cm)

Giro Agilis is the best road bike helmet under 100 for multi-terrain riding. The Giro brand makes this Agilis model with the aim to provide riders a perfect choice for road and graveling. The manufacturer has merged the round front end with a lower rear that could be seen on other mountain bike models.


Its extended back section brings better coverage, which helps you feel more secure if unexpected accidents happen. However, you still get the aesthetic and aerodynamic advantages thanks to its creative design.


On the other hand, we really appreciate its Roc Loc 5 adjustment system. You could simply tighten or loosen to get the perfect fit. In addition, coming with MIPS like other Giro products is a bonus point. This model has plenty of colors, so you could choose your favorite color to buy.


Although we like the adjustment system, our testers found that it was not an ideal helmet for long hair riders. We also surprised that it has 32 wind tunnels but our head overheating when riding this helmet for a long distance.

PROS

  • Good design for a safe ride
  • Rounded front end profile
  • Adjustment system

CONS

  • Overheating problem
  • Not inconvenient for long hair riders

LIVALL BH60SE Tail Spinners, Navigation, Support Calling and SOS System Music Light Bicycle Helmet, Unisex, BH60SE Musik, Rücklicht, Blinker, Navigation, Anruffunktion und SOS-System, black, 55-61cm
  • Control Unit: stable Bluetooth connection, Auto Reconnect, controls music/calls
  • Smart LED light system: 14 rear light LED's, 6 LED indicator
  • Intelligent design: 24 vents, extremely light, stereo sound
  • Fashionable to the minute: sporty helmet with fun factor, light weight design

Livall BH60SE is the best road bike helmet under 100 for commuting. We realize that it is difficult where to start because this helmet has many useful and interesting features that you couldn’t find on any road bike helmet under 100.


Honestly, we really love its built-in Bluetooth speakers and windproof microphone system. You can take calls, listen to music, or even GPS voice navigation once the helmet connected with your phone (Android or IOS) and Livall app.


Moreover, Livall also integrated this model to walkie-talkie ability that can allow you to talk to your riding buddy. With this function, you can contact to your partner when you become distanced from the group.


In addition, this helmet comes with SOS features. If you face an impact or sudden accidents, it will send an SOS message to 3 people you chose before to let them know you are in trouble and your location. Our experts tested this function by throwing it and catching it to check whether the system works well or not. After a countdown of 90 seconds, other people received the messages. Remember do not test without informing your partner.


Like Bell Formula, Livall BH60SE comes with an LED light system but smarter. The red lights at the main strip flash enough around the edges to be visible. The LED lights at the two helmet sections below could be changed to an amber indicator with a simple push of a button from your handlebar remote control.


On the other hand, this helmet weighs 278g and gives you a perfect fit as well as a cool air feeling by its aerodynamics design and Rear dial retention system.


However, in exchange for too many technique functions, you have to charge the helmet. After spending an amount of time for testing, the helmet could last up to 7 hours after fully charged (Not recommend for a long-distance ride if you want to use its features). Another disadvantage is that it has only one size (55 cm - 61 cm) that can not fit too many riders.

PROS

  • SOS system
  • Bluetooth built-in system
  • Aerodynamics design
  • LED system

CONS

  • Battery issue
  • Only one size

MET Unisex's Vinci MIPS Cycle Helmet, Black and RED, Medium
  • In-mould polycarbonate shell with EPS liner with MIPS-C2 technology
  • Safe-T DUO Fit System
  • Reflective rear stickers
  • Internal air-channeling

We would like to introduce you to a good road bike helmet under 100 which comes from an Italian branch - MET Vinci. This helmet has a similar design to some high-end products of this brand. It has 16 vents and internal channels that put cool air over the head. After riding for a couple of hours, we didn’t notice any temperature discomfort.


Another good point of this helmet is that it comes with MIPS standard and Safe-T DUO Fit System which give you feel more secure. The retention dial gives a good scale of adjustment.


However, we do not really appreciate its design. It has two of the vents that act as a glasses port. You may get difficult while riding on a sunny day.

PROS

  • Lightweight design
  • Retention system
  • Safe standard

CONS

  • Glasses port

Smith, Signal Mips Helmet, Bicycle Helmet, White, 55/59, Unisex-Adult
  • It offers cyclists an exceptional custom fit
  • It guarantees a tailor-made fit for each rider
  • Absolute integration you expect from a Smith helmet
  • 21 optimized ventilation holes

Smith Signal is a good road bike helmet under 100 for “every day” riders. This model has some premium design from Smith top-end products but more boxy. It comes with a high-quality in-molded construction that makes it sturdier.


We really like the VaporFit adjustable fit system. It is an easy-to-use dial system that offers you a comfortable fit. On the other hand, with 21 vents to draw air through the helmet, you can stay cool, and arrive to work without too much of a helmet hair effect. It also has MIPS standard which is a good point for road bike helmet under 100.


Unfortunately, if you see the helmet from the front, it is like a touch square and chunky. And we also don’t like its color, it has only one color version and so basic.

PROS

  • Retention system
  • MIPS standard
  • Cool air system

CONS

  • Basic look

Sale
Giro Unisex's Cormick MIPS Urban Helmet, Matte Highlight Yellow, 54-61 cm
  • In-Mold polycarbonate shell with EPS liner
  • Roc Loc Sport MIPS
  • Full Hard body shell
  • Quick-dry padding
  • Integrated MIPS technology

Another good helmet from Giro branch but for short-distance rides. Giro Cormick is lightweight by using In-Mold construction to reduce weight while enhancing durability to stand up to everyday use.


On the other hand, it also comes with MIPS standard which can protect your head from unexpected impacts. We like its Roc Loc Sport MIPS fit system that makes the helmet fit your head easily.


On the backward, it has only one size (54 cm - 61 cm) and only one color version. The manufacturer said that this helmet is unisex, but we don’t think so due to its lack of color and size options.

PROS

  • Lightweight design
  • MIPS standard
  • Retention system

CONS

  • Lack of options

Bern Unisex_Adult Union Helmet, lightblue, S
  • Bern Unlimited is a lifestyle action sports company specialising in head protection for non-motorised action sports.
  • Bern is passionate, focused and dedicated to providing skaters, snowboarders, skiers, bikers and wakeboarders with adaptable year-round head protection that suits the individual personality and style of each rider.
  • Bern's mission is to deliver products that action athletes desire before they know they want them. Bern has driven the evolution of head protection through new designs, engineering and development.
  • Bern Unlimited is a private company owned by action athletes.
  • Go out and have fun in action sports - but make sure to wear a head guard!

Let take a look at Bern Union - a helmet comes from a branch for skaters. Just kidding! Bern was born as a company for skaters, but now they have focused to specialize in head protection for non-motorized action sports. We found this helmet is really great. It comes with MIPS standard as well as sturdy build quality.


It is lightweight and we really like its design. This helmet has a removable, clip-in “visor”. You could make it like sun protection or just put on your helmet for more fashionable. Its Boa 360 Degree Retention System offers you an easy way to adjust the helmet to fit your head perfectly.


However, we do not recommend you use this helmet for long-distance rides. Its aerodynamics system doesn’t work well and give us temperature discomfort after nearly 2 hours of riding. Moreover, it only comes with one size version and two color options to choose from.

PROS

  • MIPS standard
  • Removable visor
  • Lightweight design

CONS

  • Bad aerodynamics system
  • Lack of options

Bern Men's Watts Helmet - Matte Grey, Small
  • Bern Profile with Original Visor Brim
  • Plush BOA adjustable Knit Liner
  • Thin shell Construction
  • 11 Radial Vents
  • 2 Shell sizes

Another helmet comes from Bern branch - Bern Watts. If Bern Union gives you a sportive style, in our opinion, Bern Watt helps you more stylish in the city. With a hard visor built-in like a baseball hat, this helmet keeps you to stay away whatever the weather throws at you.


In addition, we also love its design that the helmet extends to cover the back of your head which provides more protection for your trip.


Bern Watt was built with ABS shell outside and on the inside is lined with EPS foam that gives you sturdy build quality. Moreover, its premium moisture-control liner with the aim that makes you sweat-free while riding is a good point.


However, we do not highly appreciate this helmet than the Bern product above. Like its brother, this model doesn’t have a good aerodynamics system and bonus with heavyweight (nearly 500g) that can not use for long-distance rides.


You could face temperature discomfort despite having a premium moisture-control liner. Unlike the other one above, it doesn’t come with MIPS standard that reduces its value in the range of good road bike helmet under 100. In addition, it only has one black color option but luckily, you may choose widely with 3 sizes S, M, or L.

PROS

  • Stylish look
  • Premium moisture-control liner
  • Hard visor built-in

CONS

  • Lack of MIPS standard
  • Bad aerodynamics system
  • Only one color option

MET STRALE BLACK ROAD CYCLE HELMET
  • In-mould outer shell construction and shock absorbing polystyrene inner shell
  • Anti-pinch chin-strap buckle
  • Safe-T Duo fit for horizontal and vertical adjustment
  • Internal air-channeling

MET Strale is another good road bike helmet under 100 for everyday riders. We really love the sportive design of this Italian product. Like MET Vinci, this model has a lightweight design, 14 vents and internal channels that put cool air over the head. We still didn’t notice any overheating problems while using this helmet for a long time.


In our test results, its Anti-pinch chin-strap buckle worked well, although we tried many times to pinch it. Coming with Safe-T Duo fit for horizontal and vertical adjustment like MET Vinci is a good advantage to make it perfectly and easily fit your head.


However, the Italian branch doesn’t integrate MIPS standard for this model that make it less secure. In the UK market, this helmet has only black color option.

PROS

  • Good aerodynamics system
  • Sportive look
  • Anti-pinch chin-strap buckle

CONS

  • Lack of MIPS standard
  • Only black color option

Giro Unisex Foray Road Cycling Helmet, Matt Titanium/White, Medium/55 - 59 cm
  • Unisex fit
  • Streamlined design
  • Plush interior
  • In-mold polycarbonate shell with EPS (Expanded Polystyrene) Liner
  • New Roc Loc 5 fit system

Giro Foray is a good road bike helmet under 100 for short-distance rides like Giro Cormick mentioned above. It has the bold design language of other premium synthetic Giro helmets, especially like Giro Synthe - a top-end model.


It also comes with durable in-mold construction that offers a sturdy build but lightweight design. Additionally, the Roc Loc 5 fit system is equipped in this helmet. You will have an easy-to-adjust this helmet for a perfect fit for your head.


Our test results showed that its aerodynamics system worked well after nearly 3 hours of riding. Our testers didn’t face any overheating problem as Giro said that their design helps cool airflow over the head.


Unfortunately, unlike Giro Women’s Seyen and Giro Cormicks mentioned above, this model doesn’t come with MIPS standard. The manufacturer tells the reason to reduce the cost, but in our opinion, the purpose of helmets is to protect riders from unexpected accidents. Therefore, we don’t totally accept this reason. On the other hand, it has only one black color option that makes it less attractive to many riders.

PROS

  • Good aerodynamics system
  • Sportive look
  • Retention system

CONS

  • Lack of MIPS standard
  • Lack of options


We are very happy to introduce you Lazer Unisex's CZ1996013 as known as Lazer Blade +. It is a perfect combination of lightweight design and excellent performance for an affordable price.


It weighs about 230g and with the help from its Rollsy fit system, a number of our testers forgot that they were wearing a helmet while testing. Besides that, we highly appreciate its vent and internal channels system. We didn’t have any overheating problem after riding for a long time.


One special thing that makes us surprised that the barrel adjustment sits across the top of the head instead of on the back like other road bike helmets under 100. However, we faced a bit difficult to use this because it was hard to determine exactly its position.


Unfortunately, this helmet doesn’t have MIPS standards. As we said before, in our view, we do not accept the reason for the lack of MIPS to reduce the cost. Customers could find many road bike helmets under 100 that come with MIPS.

PROS

  • Lightweight design
  • Good aerodynamics system
  • Good look

CONS

  • Lack of MIPS standard
  • Weird retention system


Kask Rapido Cycling Helmet Blue Bleu Claire Size:L (59-62 cm)
  • Ventilation is achieved by means of 24 large air vents, arranged to optimise aerodynamics;
  • Expanded polystyrene shell that optimises crash impacts;
  • Size: 59-62cm

Another branch from Italy - Kash Rapido. This is not a big branch but the features that Kask brings from high-end products to their low-end products make them become a formidable competitor. The best thing we like most about this helmet is its ventilation system.


We tested this system on a sunny day, about 27 Celsius degrees with a multi-terrain ride for 2 hours, and the result was incredible. Its lightweight design and the work-well ventilation system gave us a perfect experience with this model.


On the other hand, we think its design looks cool and stylish. Instead of using MIPS standard, Kask use MIT technology for their product. It is an expanded polystyrene shell that reduces crash impacts if you face an unwanted accident. Although it has 2 color versions, we do really like their color, so that we think it is a good advantage of this helmet.


On the backward side, Kask Rapido doesn’t come with any retention system. That’s why users can face difficulty to find the perfect size for their heads.

PROS

  • Lightweight design
  • Ventilation system
  • MIT technology

CONS

  • Lack of retention system

On the other hand, like its brother, this model will make you confused while buying it because it has over 10 options colors for you to choose from.


Unfortunately, lacking MIPS standard is a big disadvantage of this product no matter how affordable it is.

Key Factors That You Should Consider When Choosing Best Road Bike Helmet Under 100

Many riders often choose road bike helmet under 100 according to its color and design. However, it is not safe for your rides if you buy a helmet like that. Let read on our expert’s guideline below to have the best road bike helmet under 100 for your trip.

Safety Standard

You should check the helmet carefully whether it was tested to the standard relevant to where you live: CPSC for the US, EN 1078 sticker for the UK, and Europe. It will ensure the helmet you are looking for passed a number of tests that check the helmet’s construction, impact prevention, retention system, and so on. 

For your safe and sound trip, we recommend you choose a helmet that is relevant to your local standard.

MIPS

This is a standard that we mentioned a lot in this review, and we always highly recommend road bike helmet under 100 having this standard. MIPS stands for Multi-directional Impact Protection System. It was developed in Sweden. It contains a smooth inner layer that’s loosely connected to the helmet’s shell. When you have accidents, the layer will slide between the helmet and your head to minimize the impact to your brain.

In our opinion, it is an essential factor that you should prioritize while buying a road bike helmet under 100. A helmet coming with MIPS often costs a little more, but we ensure that really worth it.

Fit

According to our statistics, normal riders use their helmet a lot of time, maybe up to 5 hours per day. Therefore, it is very important to find a helmet that fits your head perfectly to make you feel comfortable during the ride.


On the other hand, there are many types and shapes of helmets. Some are unisex, some are specific for women, and so on. If you want to buy online, measuring your head exactly before buying.

Retention System

As we mentioned above, choosing a fit helmet for your head is really important, and the retention system will help you adjust the helmet to fit your head easily. However, not every helmet has the same retention system. Like Lazer Blade, its retention system is hard to use that makes you feel inconvenient.

Therefore, we recommend you choose the helmet that often has its adjustment system at the back and easy to use.

Ventilation System

The vents are the holes in the shell of your helmet. It takes the responsibility to flow the cool air over your head to make you feel comfortable and stay away from overheating problems, especially in summer. In addition, some branches have improved their ventilation system to reduce the weight of theirs helmet.

Weight

Riders nowadays tend to buy lightweight helmets. It is easy to see the advantage of this trend: a light helmet will reduce the press to your head and your neck, and it will increase your performance. Although 50g doesn't affect too much that we can feel it, top professionals really care about it to ensure their performance.

Crash Replacement

Some manufacturers offer a crash replacement program, which lets you buy a new helmet at a discounted price if you have an unexpected accident. This service depends on the branch, but we think it is a good bonus and should be considered when buying a road bike helmet.

Some Types Of Road Bike Helmets

Leisure/Commuting Bike Helmets

This type of helmet often ranges under 100. It is ideal for daily normal rides. You can use these helmets to ride from home to your workplace, or around the city, or even for a long-distance ride.

Performance Road Bike Helmets

Like its name, this type is specific to professionals who want the lightest and breathable helmet. These helmets have a good ventilation system, lightweight design to ensure the rider’s performance.

Time Trial Bike Helmets

These helmets are developed for time trials and are not allowed in standard UCI road races, but are permitted in UCI TT’s if they meet the necessary safety credentials. This type of road bike helmet is contradictory to the performance type.

It has elongated or teardrop shapes to maximize aerodynamics, but it will reduce the ventilation system because the vents will create drag. We don’t recommend you use this type of helmet for normal rides because we don’t like its design.

Besides that, we would like to share with you some useful tips to clean your road bike helmet and maintain it for long term use:
