Main highlights

woom: The balance bike and children's bicycle brand from Austria accompanies the youngest on their way on two wheels from the start. The high quality standards are particularly important to give children safe fun and lots of joy from the first balance bike to the e-mountain bike.
Robust construction: the in-mould construction fuses the outer shell with the inner layer. This makes the high-quality bicycle helmet particularly light, durable and ensures more safety when cycling.
Optimal fit: with the rotary wheel on the back, the size can be precisely adjusted so that the children's helmet fits perfectly. For a comfortable fit, the interchangeable and different thickness inner pads can be combined or removed depending on the head shape and size of the child.
MAGNETIC CLOSURE: The Fidlock magnetic clasp makes it easy to open and close the buckle, so it can also be used with gloves or just one hand. In no time at all, the children's helmet sits firmly without pinching skin or hair.
Impact protection: the innovative visor made of non-toxic elastomer has been developed in such a way that its honeycomb-like structure prevents injuries to the head and face in the event of a fall. In addition, it protects against sun and rain.
