Description
Frames for children’s bicycles have to conform to strength standards and safety criteria as much as frames for the other categories do. Here, too, we put a great emphasis on their perfect geometry, tube profiling, use of appropriate materials and, last but not least, attractive design. In fact that is the main thing that decides when choosing a children’s bike.| Frame | COSMIC | |||||||||
