Two auxiliary wheels can improve the overall stability of the bicycle. In order to keep up with the growth rate of Unisex children, we designed the auxiliary wheels to be detachable to meet the different needs of children of different ages. The detachable basket can help children store some daily items. In addition, we strictly select high-quality carbon steel materials to ensure the durability of the bicycle.
