The SKKI requires no bindings or special boots The rider just leans the Trikke SKKI and the three skis carve the turns. It is much easier to learn than skiing or snowboarding and beginners always have fun on the first run. One unit can be shared by riders of all different ages, skill levels, and sizes. Feel the control of skiing with handlebars. Feel the freedom of riding without bindings. Feel something really new and really fun!
