Nutcase Little Nutty Kids Bike Helmet – Our Review Of The Extremely Popular Kids Bike Helmet

By Vaughn

I reckon Nutcase have nailed color schemes for helmets, from subdued low-key shades to multi-colored splashes, finding that right color that speaks to your kiddy is easy. After all, if your child likes the color that’s the most important thing right? As a parent, knowing it’s a good quality, safe helmet for them to wear is our main concern.

Following on from the Nutcase Baby Nutty, the Nutcase Little Nutty is the next stop in the range. Designed to fit children from around ages 3 and up, it’s a regular looking skate-style helmet on the outside with big-kid features on the inside to help with fit and function.

Let’s face it, kids are getting more and more adventurous with their wheeled activities and finding a helmet that keeps up with them is essential. Read on for more about the Little Nutty.

Fit and Sizing

The Little Nutty would be a perfect, first ride-to-school helmet. Although it looks like a regular skate helmet, inside you will find a dial adjustment common on most sports helmets. This makes adjusting for different increments in head sizes easy and also for long hair, once it’s set it’s done, you don’t need to re-adjust it everytime your child puts their helmet on.

When comparing the Baby Nutty (47 – 50 cm) to the Little Nutty’s 48 – 52 cm measurements, there’s overlap in the sizing, in appearance the Little Nutty is quite a bit larger on a pre-schoolers head. If your child head circumference measures in the upper size range of the Baby Nutty, go for the Little Nutty, it has extra pads included helping reduce the internal size of the helmet while still being safe. These can be mixed and matched inside the helmet which is a great idea.

These types of helmets (the bowl style) rely on the pads giving a snug fit, this keeps it from moving around and it’s the safest way to wear them. Also because they are heavier the pad setup is pretty important.




Durability is the feature here. Externally the Little Nutty uses a thick but still lightweight ABS plastic exterior. It’s a one-piece shell with no weak points. This helps long-term resistance to bumps and bruises and stops cracks forming which can be common with lighter weight, highly ventilated designs.

Inside the Nutty, there’s the EPS foam liner which has ventilation channels molded in to help with airflow to the top vents. It’s a downside of the skate helmets, the vents are small so things can get warm on hot days and any type of ventilation helps.

A common feature for securing straps to the hard outer shell of skate helmets is the use of rivets, these are also used on the Little Nutty. The main benefit of having the straps permanently fastened into place is when it’s hung on the handlebars, the strap’s don’t come out of adjustment making it a nuisance to re-center everything. Also, it’s super simple and the straps are secured to the hard outer and not the glued-in liner.

Shape and Design

Classic in looks but the color combinations are wild, from ladybugs to flowers, lemons to frogs it’s all there. I would love to know how they come up with these colors, there must be people with a good imagination at Nutcase!

The Little Nutty provides good overall coverage and comes down just far enough behind the head, just stopping to give access to the dial adjuster. It follows the lines of many other skate brand helmets and it’s tried and true.

A couple of small vents in the front feature as eyes for the ladybug colorway which is convenient. Also, there’s a handy plastic visor which just slides into the front area, it’s a firm fit so it shouldn’t go missing straight away, fingers crossed.

Buckle and Adjustment

The Nutcase magnetic buckle, or Fidlock, is an interesting unit, all you really have to do is hover the two clips near each other and they automatically grab hold. It takes extra time to figure out but works well and saves the dreaded neck pinch.

Another nice feature is the soft sleeve covering the chin strap, it’s super soft and gives a little bit of extra comfort.

Under the ears the straps meet via simple sliding clasps, these are non-locking and simply pull into place. Nice and simple but they sometimes can migrate from their position so just check to make sure they’re still in the right place from time to time.

The dial adjuster actually has a reflective sticker on the back of the dial and uses a rubber covered exterior for better grip. The plastic connections holding the dial assembly in place are thick enough to withstand daily use so breakage shouldn’t be an issue.
