Cycling can not only help promote the healthy growth of children, but also help them improve their balance ability.Our training bike can help children quickly master riding skills under safe conditions. The 18'' wheels are not only non-slip but also adaptable to different roads. Two auxiliary wheels can improve the overall stability of the bicycle. In order to keep up with the growth rate of children, we designed the auxiliary wheels to be detachable to meet the different needs of children of different ages. In addition, we strictly select high-quality carbon steel materials to ensure the durability of the bicycle. Besides, in order to ensure the safety of children when riding in dim light, we have installed reflector on the wheels and seats.
