For a perfect look on my bike, I wear my red helmet! To protect yourself while looking stylish, match your helmet to your Bikloon and let's go for long rides in the park or in the forest! This helmet matches the Janod Bikloon balance bikes. With its adjustable head size from 47 to 54 cm (18.5 to 21.3") thanks to a knob, this helmet for children will evolve with little ones and is suitable for children from 3 years old. The comfort foams are removable, and 11 ventilation holes and 3 adjustment points (strap crosses, a chinstrap clip and a knob) allow for quick and easy comfort and adaptability.
