NOTE: When using any helmet with a Spin Dial adjuster, do not over-tighten. Choose your size by measuring up and checking our Nutcase Perfect Fit Guide

Q. My child is 1 year old, will the Little Nutty helmet fit?
Our lightweight Baby Nutty range is designed for babies aged 1 year to approximately 2.5 or 3 years old.We don’t recommend Little Nutty for any child aged 2.5 years old or less as young children need time to develop neck strength in order to have optimal benefit from a helmet.
Little Nutty is designed for use by toddlers aged approximately 3-6 years with a head circumference measuring 46cm – 52cm. It is adjustable to the maximum size with a Spin Dial.

Q. When is it safe for a baby to use a Nutcase helmet?
We receive many questions from parents, with children aged 6 weeks onward, who wish to ride with them in a bike seat, trailer or chariot. No studies we are aware of have recommended that it is safe for children this young to ride in bike seats, trailers or chariots – even if they have a helmet fitted. In some cities, such as New York, it is prohibited to ride with a child under 12 months.
Trailers/chariots are close to the road and parents often forget how rough the ride can be. A normal slow ride can present serious jolts to a young baby’s neck. Adult riders also need to be competent to avoid the most common crashes (which occur standing still). 
We recommend seeking advice from a medical professional such as your Paediatrician or Baby Health Nurse if you are unsure.

Q. My toddler measures 51cm already. I want to save some money, should I go up a size?
Helmets, bicycles or any piece of equipment which does not fit the rider properly can be dangerous at worst and uncomfortable at least.
As a guide, children do the most amount of growth in their entire lives between the short time of birth to 12 months old. They grow approximately 25 cm on average in just 1 year! After that, growth is incremental. The next growth spurt is puberty (8-13 years for girls, 10-15 years for boys). Then its onto adulthood between ages 17-21.
For any helmet to be used optimally, it must be fitted properly: ensure you measure up, adjust the straps, insert the right thickness of foam pads and use the spin dial adjuster gently (do not over-tighten).
The Gen 3 Nutcase Street helmets measurements range from 52 – 60cm. Even with the thickest padding inserted in the Small (52-56cm) to bring it down to 52cm, your toddler will be wearing a pretty big helmet shell (max 56cm) for a long time.
Strap adjustments may not prevent the oversized helmet from slipping backwards on a toddler. If the toddler experiences a fall and the helmet has slippage, it may not protect their temples and frontal lobe adequately.
See the Nutcase Perfect Fit Guide and always measure your child. Or, ideally, fit the helmet at one of our Nutcase Dealer stores if your child is on the size threshold and you are unsure.

Q. My measurement is on the border of your sizes, how do I choose the right size?

All kids and adults are different in size and shape.In general babies aged 1+ fit into the Baby Nutty range. Sometimes babies aged 2.5 years will be strong and sized well enough for a Little Nutty.Toddlers aged 3 – 6 years fit the Little Nutty range. Children over the age of about 6-7 years may be better suited to the Street or Zone Small size.  Tweens and teens aged 12 and upwards, along with adults will fit into the Street or Zone Medium in many cases.A minority of adults may fit the Street Large but we suggest checking the Nutcase Perfect Fit Guide to be certain as the Large runs to a 64cm shell and is significant in size.

Q. How do I create a custom fit for Street and Little Nutty helmets?
Little Nutty and Street helmets are fitted with a Spin Dial Fit System, see instructions in the box and below. Over-tightening the spinner may seize the system. If you need a snugger fit, the helmet may need the thicker padding set from your helmet box. Remove the default pads, and replace with thicker or thinner pads to customise. Baby Nutty has a soft velcro Fit System.

Q. How often should I replace my helmet?
Helmets have a normal lifespan of 2-3 years and should be replaced approximately every 2-3 years due to normal factors such as growth or wear and tear.
Nutcase Little Nutty, Street, Water and Snow helmets are classed generally as ‘single impact’. If you are in a crash, serious fall or accident, the helmet should be replaced immediately. This is because the thick black/grey EPS liner which absorbs impact may be damaged. Watch this video about the science and physics of safety gear. To extend the wear of your helmet, take care to store it inside when possible; avoid exposing it to the elements by leaving it in rain, snow or heat when not being used, avoid using thinners or abrasive cleaners on the surface and replace soft foam pads when required.
