A French SME has invented and designed a hand trolley system that clips onto a hoverboard to facilitate the transport of goods on foot. Its handles modulate the forward speed and makes it possible to brake if necessary. The SME seeks an industrial partner specialising in metal tubes (steel or aluminum) folding, welding, capable of adapting mechanical parts (braking system). A long-term partner located in Eastern Europe is sought for a manufacturing agreement. A prototype will be made initially.
