The Smith Sidekick Jr Mips Bicycle Helmet is an essential safety accessory designed specifically for young cyclists aged 51cm to 55cm. It offers the critical benefit of Mips technology to mitigate rotational impact forces during a fall, ensuring superior head protection compared to standard foam helmets. While it provides excellent coverage and durability, parents should note that it is designed strictly for youth sizing, making it unsuitable for riders who exceed the 55cm head circumference limit.

Mips stands for Multi-directional Impact Protection System, a technology designed to reduce rotational forces that can result from certain impacts.
Measure the circumference of your child's head at the widest point; if it falls between 51cm and 55cm, this helmet is the correct size.
It is generally recommended to avoid applying stickers or paint, as chemicals in adhesives or solvents can potentially damage the shell integrity.
You should replace the helmet immediately after any significant impact, or if the protective foam or shell shows signs of wear and age.
No, the Smith Sidekick Jr is designed specifically for bicycle use and should not be used for motorized vehicles.
Ensure the chin strap is properly tightened and the interior padding is correctly positioned.
Gently loosen the tension by sliding the locking mechanism fully before repositioning the webbing.
To ensure proper fit, measure the child's head circumference just above the eyebrows. The helmet should feel snug without creating pressure points. When adjusting the straps, ensure the Y-junction of the side straps sits just below the ears and the chin strap is tightened so that only one or two fingers fit between the strap and the chin. To care for your helmet, clean the outer shell with mild soap and water only; avoid using household cleaners or solvents which can degrade the protective materials. Periodically check the shell for any signs of cracks or deep scratches; if the helmet sustains a significant impact, it must be replaced immediately, even if no damage is visible.
