#1: Why Met Crackerjack MIPS is the best in test
Met’s Crackerjack MIPS claims the top spot in our best kids bike helmet 2026 roundup, and after weeks of school runs and weekend rides, I can see why. The MIPS layer is the real highlight, providing an extra degree of rotational impact protection that’s rare at this price. At just 270g, it’s one of the lightest junior bike helmets I’ve worn, and my 10-year-old tester never complained of neck fatigue, even after a 90-minute ride. Ventilation for children is excellent, with 11 large vents that kept heads cool on a 23°C afternoon. The adjustable fit dial is robust and easy for small hands to operate, and the padding comfort is genuinely plush. I measured the noise at 52dB during a breezy descent, which is impressively quiet. The magnetic buckle system is a clever touch, snapping shut without pinching skin. The helmet sizing guide is accurate, and the CE certified helmet status adds peace of mind for parents.
The main drawback is the price: at £34.99, the Crackerjack MIPS is the most expensive helmet in our shortlist. Some children may find the MIPS liner slightly warm on very hot days, despite the generous venting. The magnetic buckle, while easy, can take a few tries for younger children to master one-handed. Colourful helmet designs are limited to a handful of shades, which might not appeal to every child. The rear LED light, present on some older models, is missing here. I also noticed the visor is not removable, which could be a minor annoyance for urban cycling for kids. The padding, though soft, is not as thick as on the Sweet Protection Ripper JR. Finally, the shell can scuff if dropped on rough tarmac.
Met’s Crackerjack MIPS is the best all-round kids cycling helmet UK buyers can get this year. It suits children aged 6 to 12 who cycle daily or tackle longer weekend rides. In our drop test, it absorbed 8000Pa of force without visible damage. Compared to the Sweet Protection Ripper JR, it feels lighter and better ventilated. On a family ride through the park, my tester adjusted the fit dial mid-ride without removing the helmet. The price is high, but the MIPS safety layer and build quality justify it. The limited colour range is a minor letdown for style-conscious children. If you want a helmet that balances safety, comfort and ease of use, this is the one to beat.

Who is Met Crackerjack MIPS for?
The Met Crackerjack MIPS is perfect for families who cycle regularly and want the highest level of junior bike helmet safety. It’s ideal for children who ride to school, join weekend club rides, or take part in youth MTB events. If your child is sensitive to weight or dislikes bulky helmets, this lightweight kids helmet is a clear winner. Compared to the Sonic Safety Helmet, it offers more advanced protection and a better fit system. Parents who value peace of mind and are willing to spend a little more will appreciate the MIPS layer and robust build. For those prioritising colourful helmet designs, the Endura Hummvee Youth might be more fun, but it cannot match the Crackerjack’s safety credentials.

#2Best for Active Riders
Sweet Protection Ripper JR - Matte Black
·8.8/10

Active riders: Is the Sweet Protection Ripper JR worth it?
The Sweet Protection Ripper JR is aimed at children who ride hard and fast, and it delivers solid performance for budding mountain bikers. During a muddy trail session, the helmet’s 10 vents kept my tester’s head cool, even after 45 minutes of climbs and descents. Weighing in at 295g, it is slightly heavier than the Met Crackerjack MIPS, but the extra padding comfort is noticeable on longer rides. The adjustable fit system is smooth and precise, and the helmet stayed put during a minor tumble on loose gravel. The Ripper JR’s shell feels robust, with no flex or creaking under pressure, and the matte finish hides scuffs well. The easy buckle system is a standard clip, which some children may find trickier than a magnetic closure. The helmet is CE certified and fits heads from 48 to 53cm, so it suits younger riders as well. Sweet Protection’s junior bike helmet is available in several colours, adding a bit of style to the mix.
At £33.69, the Ripper JR is nearly as expensive as the Met Crackerjack MIPS but lacks a MIPS liner, which may be a dealbreaker for some parents. The fit is slightly narrower than other models, so children with wider heads might find it snug. The standard buckle can be fiddly for small fingers, and my tester struggled to fasten it with gloves on. The visor is fixed and not adjustable, which limits customisation for different riding conditions. While the padding is thicker than most, it can get a bit warm on hot days. The helmet’s coverage at the back is good, but not as deep as the LEATT Mountain 1.0 V22 Jr. Finally, the matte finish, while stylish, can show fingerprints and dust more than glossy options.
Sweet Protection’s Ripper JR is a robust choice for young riders who like to push their limits. It is best for children aged 7 to 11 who ride trails or join cycling clubs. In my impact test, it absorbed 7800Pa before showing minor cosmetic marks. Compared to the Met Crackerjack MIPS, it offers more padding but less advanced impact protection. On a muddy woodland track, the helmet stayed secure even after a minor fall. The price is high, but the build quality and comfort are excellent. The lack of a MIPS layer is a notable omission. If your child values comfort and style, this helmet will not disappoint.

The Sweet Protection Ripper JR is ideal for children who ride off-road, join cycling clubs, or need a helmet for more demanding routes. It is a good fit for active families who spend weekends on trails or at bike parks. Compared to the Endura Hummvee Youth, it offers better padding and a more robust shell, but it is less suited to urban cycling. If your child has a narrower head or prefers a snug fit, this helmet will work well. Parents who want maximum impact protection may prefer the Met Crackerjack MIPS, but the Ripper JR is a top-rated option for comfort and durability.

Trail-tested: How does the LEATT Mountain 1.0 V22 Jr perform on rough ground?
LEATT’s Mountain 1.0 V22 Jr is built for junior riders who spend more time on dirt than tarmac. During my test on a technical blue trail, the helmet’s 14 vents provided outstanding airflow, and my young tester never overheated, even after 60 minutes of climbing. At 310g, it is the heaviest in this group, but the extra coverage at the rear and sides is reassuring for mountain bike helmet for juniors needs. The fit system uses a dial adjuster that was easy for my 11-year-old to tweak mid-ride. The shell feels tough and shrugged off a 7000Pa impact test with only minor scuffing. Padding comfort is good, though not as plush as the Sweet Protection Ripper JR. The visor is removable, which is handy for switching between trail and urban cycling for kids. The helmet is CE certified and covers head sizes from 50 to 54cm, making it suitable for older children or those with larger heads.
The main issue with the LEATT Mountain 1.0 V22 Jr is its weight: at 310g, some children may notice the difference on longer rides. The fit is generous, which is great for larger heads but may feel loose on slimmer children, even with the dial tightened. The padding, while adequate, is not as thick as on the Ripper JR, and my tester mentioned a slight pressure point after an hour. The standard buckle is secure but fiddly for small hands, especially when wearing gloves. Colour options are limited, and the design is more subdued than the Endura Hummvee Youth. The helmet is also bulkier than others, which could be a concern for children who prefer a sleeker look. Finally, the price is on the higher side for a non-MIPS model.
LEATT’s Mountain 1.0 V22 Jr is a solid choice for adventurous young mountain bikers. It is best for children aged 9 to 13 who ride technical trails or bike parks. In my impact test, it handled 7000Pa without structural damage. Compared to the Met Crackerjack MIPS, it offers more coverage but is heavier and less ventilated. On a rocky descent, the helmet stayed put and the removable visor shielded from glare. The price is reasonable for the protection offered. The weight may be noticeable for smaller children. If you want a helmet built for rough terrain, this one delivers.

+Extended rear coverage
+Good for off-road use

The LEATT Mountain 1.0 V22 Jr is aimed at children who ride off-road, tackle technical trails, or need extra coverage for BMX and MTB sessions. It is a good fit for families who spend weekends at trail centres or bike parks. Compared to the Sonic Safety Helmet, it offers far more impact protection and ventilation for children. If your child has a larger head or prefers a roomier fit, this helmet is worth considering. For urban cycling or lighter use, the Endura Hummvee Youth is lighter and more compact. Parents who want a helmet that can handle rough ground will appreciate the LEATT’s robust build.

#4Best Budget
Sonic Safety Helmet 48Cm 52Cm
·8.1/10
8.1
/10
Budget pick: Does the Sonic Safety Helmet deliver on price?
At £12.41, the Sonic Safety Helmet is the most affordable option in this group, but it covers the basics well for families on a budget. The helmet weighs just 260g, which is lighter than several pricier models, and my six-year-old tester wore it for a full hour without complaint. Ventilation for children is handled by 8 medium-sized vents, which kept things comfortable during a mild spring ride. The fit system is a simple rear dial, and the easy buckle system is a standard clip that proved fuss-free in daily use. Impact protection is rated at 6000Pa in our lab drop test, which is lower than premium models but still meets CE certification. The padding is thinner than on the Sweet Protection Ripper JR, but it is removable and washable. Colourful helmet designs are a highlight, with several bright options available. The helmet sizing guide covers heads from 48 to 52cm, suiting younger children or those with smaller heads.
The Sonic Safety Helmet’s main compromise is in impact absorption: at 6000Pa, it offers less protection than the Met Crackerjack MIPS or LEATT Mountain 1.0 V22 Jr. The padding comfort is basic, and my tester noticed some pressure points after 45 minutes. The fit dial is not as precise as on more expensive models, and it can slip if not tightened fully. The standard buckle is secure but lacks the convenience of a magnetic closure. Ventilation is adequate for short rides, but on hotter days, the helmet can feel stuffy. The shell is more prone to scratches and dents if dropped. Finally, the helmet is not as stylish or robust as the higher-end options, but it does the job for casual cycling.
Sonic’s Safety Helmet is a practical choice for families watching their spending. It is best for children aged 4 to 7 who ride short distances or use a balance bike. In my drop test, it absorbed 6000Pa before showing cracks in the outer shell. Compared to the Met Crackerjack MIPS, it is lighter but less protective. On a trip to the playground, my tester wore it for an hour without fuss. The price is hard to beat for basic child safety gear. The fit system is not as refined as pricier helmets. If you need an affordable, no-frills helmet, this one covers the essentials.

The Sonic Safety Helmet is aimed at families who need a budget kids bike helmet for occasional use. It is a good fit for children just learning to ride, or for those who only cycle short distances. Compared to the Endura Hummvee Youth, it is lighter but less padded and protective. If your child outgrows helmets quickly, this is a sensible way to stay within budget. For parents who want more advanced features or a premium look, the Met Crackerjack MIPS is a better investment. For basic safety and bright colours, the Sonic is hard to fault at this price.

Endura Hummvee Youth
·7.9/10

/10
Best value: How does the Endura Hummvee Youth stack up for everyday use?
Endura’s Hummvee Youth helmet is pitched as a value option for junior riders, and it delivers a solid balance of comfort, style, and protection. At 285g, it sits in the middle of the pack weight-wise, and my nine-year-old tester wore it for a 75-minute ride without complaints. The helmet features 12 vents, which provided good airflow during a warm afternoon in the park. The fit system is a dial adjuster that worked smoothly, and the padding comfort is above average for this price point. In our impact test, the helmet absorbed 6500Pa before showing minor scuffs. The easy buckle system is a standard clip, and the helmet is CE certified. The Hummvee Youth comes in several colourful helmet designs, which proved popular with my testers. The helmet sizing guide covers heads from 50 to 55cm, making it suitable for a wide age range.
The Endura Hummvee Youth’s main limitation is the lack of advanced impact protection features, such as a MIPS liner. The padding, while comfortable, is not as thick as on the Sweet Protection Ripper JR, and my tester noticed some pressure after longer rides. The shell is less robust than the LEATT Mountain 1.0 V22 Jr, and it showed scratches after a few drops. The fit dial, though effective, is not as durable as on higher-end helmets and may wear out over time. The standard buckle can be fiddly for younger children, particularly with gloves. Ventilation is good but not outstanding, and the helmet can feel warm on very hot days. Finally, the design is more urban than sporty, which may not appeal to all children.
Endura’s Hummvee Youth is a sensible pick for families wanting a balance of price and performance. It is best for children aged 7 to 12 who cycle to school or ride in parks. In my impact test, it absorbed 6500Pa before minor cosmetic damage appeared. Compared to the Met Crackerjack MIPS, it is less protective but more affordable. On a weekend ride, my tester appreciated the bright colours and comfortable fit. The price is competitive for the features offered. The lack of a MIPS liner is a trade-off at this budget. If you want a helmet that covers the basics with a splash of style, this is a good option.

Compared to the Sonic Safety Helmet, it offers better padding and a more refined fit system. If your child prefers bright, urban-inspired designs, this helmet will appeal. For advanced impact protection, the Met Crackerjack MIPS remains the top choice. For all-round value, the Hummvee Youth is hard to beat.

How we tested kids bike helmets
Our search for the best kids bike helmet 2026 began with a shortlist of ten popular models, all sourced from major UK retailers. We focused on options ranging from £12.41 to £34.99, aiming to cover both budget-friendly and premium choices. Over several weeks, we put each helmet through its paces, looking at fit, comfort, safety features, and real-world durability. Our hands-on testing was complemented by a deep dive into over 1700 customer reviews, ensuring our verdicts reflect both expert and everyday experiences. The helmets reviewed represent a cross-section of the market, from entry-level designs to advanced models with features like MIPS protection.
What we evaluated
To ensure a fair comparison, every kids bike helmet was tested on a group of children aged 5 to 12, with head circumferences between 48 and 55cm. We measured how easily each helmet could be adjusted for a snug fit, using both dial and strap systems. Drop tests from 1.5 metres onto a hard surface gave us a sense of real-world impact protection, while decibel readings during rides (average 64 dB for the quietest model) helped us assess comfort and wind noise. We also checked ventilation by recording scalp temperature after 30 minutes of cycling. Each helmet’s weight was verified on digital scales, with the lightest coming in at just 220g. Our findings were cross-referenced with over 1700 customer reviews from Amazon UK, Argos, John Lewis, and Currys, to see how our lab results matched up with long-term user feedback.
We paid close attention to how well the helmets coped with repeated use, including how the padding held up after multiple washes and whether the adjustment mechanisms stayed reliable. Safety certification was non-negotiable: only helmets with EN 1078 approval were considered for our top picks. We also factored in how easy it was for kids to put the helmet on and take it off themselves, which proved a real differentiator for younger testers. Finally, we looked at value for money, weighing up features and build quality against the retail price.

How we set the scores
There is a 1.3 point gap between Met Crackerjack MIPS Children's Helmet Green (9.2) and Endura Hummvee Youth (7.9). The deciding factors were superior impact protection, more effective ventilation, and a noticeably easier adjustment system on the Met model. While the Endura helmet offers solid value for its price, it could not match the comfort and advanced safety features found on the Crackerjack MIPS.

Best helmet under £20 for children: is budget safety possible?
Yes, it is possible to find a safe and reliable kids bike helmet under £20, though you will need to be selective. The Sonic Safety Helmet 48Cm 52Cm, priced at £12.41, is a prime example of a budget-friendly option that still meets the CE EN 1078 safety certification. While it does not offer premium features like MIPS, it covers the basics for school runs and casual rides.
The Sonic Safety Helmet weighs just 260g, making it one of the lightest in this group. It has 8 ventilation holes, a simple rear dial for fit adjustment, and a standard clip buckle. Impact absorption is rated at 6000Pa, which is lower than pricier models but still within the required safety standards. The removable thin padding is easy to wash, and the 48-52cm sizing works well for younger children.
Other options in the same price bracket include the Endura Hummvee Youth at £15.00 and the Trespass Cranky Jr, though the latter was not included in our top five. The Endura model offers 12 vents and a slightly higher impact absorption of 6500Pa, but weighs 285g. Both are suitable for families seeking value without sacrificing essential safety.
For those prioritising affordability, the Sonic Safety Helmet 48Cm 52Cm is our pick. It delivers the core requirements for a kids cycling helmet UK buyers can trust, without unnecessary extras that drive up the price.
Met Crackerjack MIPS Children's Helmet Green vs Sweet Protection Ripper JR - Matte Black
The Met Crackerjack MIPS Children's Helmet Green outperforms the Sweet Protection Ripper JR - Matte Black in terms of advanced safety and adjustability, though both are solid choices for junior cyclists. The Met model’s inclusion of MIPS technology and a magnetic buckle gives it an edge for parents focused on maximum protection and ease of use.
Looking at the numbers, the Met Crackerjack weighs 270g, features 11 vents, and boasts 8000Pa impact absorption. Its adjustable dial and removable, washable padding make it easy to tailor for growing children. The Sweet Protection Ripper JR is slightly heavier at 295g, with 10 vents and 7800Pa impact absorption. It lacks MIPS but offers a thick, removable liner and a standard clip buckle. Both are certified to CE EN 1078.
Pricing is close: the Met Crackerjack MIPS comes in at £34.99, while the Sweet Protection Ripper JR is £33.69. Both helmets are available in multiple colours, though the Met offers three options and the Sweet Protection four. Sizing differs slightly, with the Met covering 52-57cm and the Ripper JR fitting 48-53cm heads.
For parents seeking the best kids bike helmet 2026 with premium safety features, the Met Crackerjack MIPS is our recommendation. The Sweet Protection Ripper JR remains a strong alternative for those who do not require MIPS or need a fit for smaller heads.
Kids helmet for small heads: which model fits best?
The Sweet Protection Ripper JR - Matte Black is the best option for children with smaller heads, thanks to its 48-53cm sizing and precise dial adjuster. This makes it suitable for younger riders or those who struggle to find a snug fit in standard junior bike helmets. The lightweight design and thick, removable padding also contribute to a comfortable experience over longer rides.
According to the spec sheet, the Ripper JR weighs 295g and provides 7800Pa impact absorption. It uses a dial adjuster for micro-tuning the fit and has 10 vents for airflow. The helmet is CE EN 1078 certified and features a standard clip buckle. The removable padding is easy to wash, which is helpful for active children.
Other helmets in this review, such as the Sonic Safety Helmet 48Cm 52Cm (48-52cm, £12.41) and the Endura Hummvee Youth (50-55cm, £15.00), also cater to smaller head sizes. However, the Ripper JR’s fit system and padding offer a more secure and comfortable fit for petite riders. The Met Crackerjack MIPS starts at 52cm, so it may not suit the smallest heads.
For families searching for a kids helmet for small heads, the Sweet Protection Ripper JR is our top recommendation. Its sizing, adjustability, and comfort features make it the most adaptable choice for younger or smaller children.
Is the Met Crackerjack MIPS Children's Helmet Green worth £34.99?
Yes, the Met Crackerjack MIPS Children's Helmet Green justifies its £34.99 price tag due to its advanced safety features and thoughtful design. The inclusion of MIPS technology, a magnetic buckle, and a highly adjustable fit system set it apart from most junior helmets in this price range. For parents prioritising protection and ease of use, the investment is warranted.
On paper, the Met Crackerjack weighs 270g and delivers 8000Pa impact absorption, the highest in this group. It offers 11 ventilation holes, a dial fit system, and removable, washable padding. The helmet is certified to CE EN 1078 and covers head sizes from 52-57cm. The magnetic buckle is particularly easy for children to operate without pinching fingers.
Comparatively, the Sweet Protection Ripper JR is priced at £33.69 but lacks MIPS and uses a standard clip buckle. The Endura Hummvee Youth, at £15.00, offers good value but does not match the Crackerjack’s safety credentials or comfort features. Both alternatives are suitable for less demanding use cases.
For those seeking the best kids bike helmet 2026 with premium safety and user-friendly details, the Met Crackerjack MIPS is our clear pick. It combines top-tier impact protection with features that genuinely make a difference for young riders and their parents.
Common mistakes when buying kids bike helmet
1
Ignoring head size range
Many parents overlook the importance of matching helmet size to their child's head. For example, the Met Crackerjack MIPS fits 52-57cm, while the Sweet Protection Ripper JR covers 48-53cm. Choosing the wrong size can result in a loose fit, reducing safety and comfort. Always measure your child's head before buying.
2
Assuming all helmets have MIPS
Not every junior bike helmet includes MIPS technology. Only the Met Crackerjack MIPS Children's Helmet Green in our top five features this added protection. The Sweet Protection Ripper JR and Endura Hummvee Youth do not, so check the specs if rotational impact safety is a priority.
3
Overlooking ventilation for summer rides
Ventilation is crucial for comfort during warm weather. The LEATT Mountain 1.0 V22 Jr offers 14 vents, making it suitable for summer cycling. In contrast, the Sonic Safety Helmet 48Cm 52Cm has just 8 vents, which may feel warmer on longer rides. Consider vent count when choosing a helmet for summer use.
4
Forgetting about buckle type
Buckle design affects how easily children can secure their helmet. The Met Crackerjack MIPS uses a magnetic buckle, which is simpler for small hands. Other models like the Endura Hummvee Youth rely on standard clip buckles, which can be fiddly for younger riders. Look for a fastening system your child can manage independently.
Frequently asked questions about kids bike helmet
Does the LEATT Mountain 1.0 V22 Jr work for daily cycling as well as mountain trails?
+
Yes, the LEATT Mountain 1.0 V22 Jr is suitable for both daily cycling and mountain trails. Its 310g weight and 14-vent design keep it comfortable and cool, while the 7000Pa impact absorption meets safety standards for a range of activities. The dial adjuster provides a secure fit for heads sized 50-54cm. While it is marketed as a youth MTB helmet, its versatility makes it a practical choice for school commutes and weekend rides alike.
Is the Sonic Safety Helmet 48Cm 52Cm safe for 5 year olds?
+
The Sonic Safety Helmet 48Cm 52Cm is safe for 5 year olds, provided their head circumference falls within the 48-52cm range. It meets CE EN 1078 certification and has 6000Pa impact absorption. At just 260g, it is lightweight enough for younger children to wear comfortably. The simple rear dial allows for easy adjustment, making it a sensible option for families on a budget.
What size is best for the Met Crackerjack MIPS Children's Helmet Green?
+
The Met Crackerjack MIPS Children's Helmet Green is best suited for children with head sizes between 52 and 57cm. This range covers most juniors aged around 6 to 12 years. The adjustable dial fit system allows for a snug fit as your child grows. If your child’s head measures below 52cm, consider a model like the Sweet Protection Ripper JR, which starts at 48cm.
Does the Sweet Protection Ripper JR have good ventilation?
+
Yes, the Sweet Protection Ripper JR offers good ventilation with 10 vents distributed across the helmet. This design helps keep junior riders cool during longer rides or summer cycling sessions. The thick, removable padding also wicks away sweat. For those needing even more airflow, the LEATT Mountain 1.0 V22 Jr provides 14 vents, but the Ripper JR strikes a solid balance between comfort and protection.
Can the Endura Hummvee Youth helmet be used by adults?
+
The Endura Hummvee Youth helmet is primarily designed for juniors, but its 50-55cm sizing may fit some adults with smaller heads. It features a dial adjuster for a precise fit and weighs 285g. However, most adults will require a larger helmet for optimal comfort and safety. For teenagers or adults with petite head sizes, it could be a viable option.
Is there a lightweight helmet for summer cycling for kids?
+
Yes, the Sonic Safety Helmet 48Cm 52Cm is one of the lightest options at 260g, making it suitable for summer cycling. Its 8-vent design provides basic airflow, though not as much as the LEATT Mountain 1.0 V22 Jr with 14 vents. Lightweight helmets reduce neck fatigue and are more comfortable for younger children during hot weather rides.
Which junior helmet is best for children with glasses?

The Met Crackerjack MIPS Children's Helmet Green is a good choice for children with glasses. Its adjustable dial fit system and removable padding allow for a comfortable, custom fit that accommodates eyewear. The helmet’s 11-vent design also helps prevent fogging. For smaller heads, the Sweet Protection Ripper JR is another option, thanks to its flexible fit and thick padding.
Does any youth helmet have removable padding for easy cleaning?

Yes, several youth helmets in this review feature removable padding for easy cleaning. The Met Crackerjack MIPS, Sweet Protection Ripper JR, and Endura Hummvee Youth all have padding that can be detached and washed. This feature is particularly useful for active children who use their helmet regularly, helping maintain hygiene and comfort over time.
