The X-mini features a multiple-adjustment design for the frame angle, the handlebar distance and saddle height to provide kids with the best possible riding experience. The X-mini could be applicable to children from the age of two to five. The adjustable wheelbase is the most remarkable strength of the X-mini: the longer the wheelbase, the more riding stability for the child; the shorter the wheelbase, the more flexible is the steering. In this way, the X-mini makes the riding fun for children who grab the grips of a bike for the first time in their life. Streamlined looks, aluminum 100% CNC machined made; light weight of 2,470 g and folding frame make it easy to carry. The X-mini is patented in over 30 countries and proved by EN-71, ASTM F963-11, CPSIA etc., safety insured.
