Excellent Helmet for Kids

My daughter loves this helmet for the two-tone combination of pink hues. I love it coz it is durable enough to protect my child as she learns how to bike. She look forward in her learning sessions and asked my husband to remove her training wheels on the 3rd session. She now knows how to ride the bike w/o the training wheels. Thanks Decathlon!

Great helmet - with matching bike to boot

Got this helmet together with the robot bike as my son loved the robot design. Matches perfectly and is comfortable and hardy. Just a thought, we paired it with the bandanas and cycle caps - from decathlon - to prevent excessive sweat collecting in the helmet and the pads internally so it doesn’t smell and require too much cleaning post the ride. Son (4 years old) is loving the helmet.

Hi Darius!

Thank you for your review for the 520 Robot Children's Helmet! 

I'm really happy to hear that you son really love the robot design by us! Apart form the cute design, this helmet is designed and catered for the young ones (3-10yrs old) who started cycling at the early age. The pre-adjusted straps helps to provide an optimized fitting so they will be comfortable throughout their cycling session. Safety should be comfortable at the same too right? ☺️

I hope you and your lovely son enjoys the purchase of this helmet. I wish you a great week ahead with your loved ones. Stay safe, fit and healthy!

Dětská helma

Pěkně sedí na hlavě, je super

Dobrý výrobek

Pro malé dítě s větším obvodem hlavy super. Výborně sedí a je růžová. To je důležité. Asi je i pohodlná, protože si ji malá sama od sebe bere. Dříve s jinou helmou bylo přemlouvání, aby si ji vůbec vzala. Jedna malinká nevýhoda je, že pásky kolem uší jsou sešité a nedají se nastavit. Jinak ale spokojenost.

Zcela vyhovuje požadavkům na levnou dětskou helmu.

* Krásně sedí na hlavě. * Krásný design pro chlapečka, jinou už nechtěl ani vyzkoušet. * Lehká a krásně sedí na hlavě. * Má polstrované vycpání u řemínku na brady.
