The Eco-Biker is a wind turbine toy that helps kids understand this form of alternative energy. Kids can clip it to a bike's handlebars or anywhere in the breeze, and watch as the fan powers a LED light. The stronger the wind, the faster the Eco-Biker pedals, and the brighter the LED shines. Eco-friendliness, sustainability, and energy-consciousness are the focus of this toy. Similar kits are purely for experimental purposes; but this small kit with a compact and highly efficient design makes it easy for kids to play and learn at the same time. 45 pieces; takes an average of 20 minutes to assemble.
