It's hard to imagine a fully collapsible 5.3m RIB that only weighs 110kg. I wonder what the transom is made of - it looks thin in the pictures. If this boat works as claimed and proves to be durable, it would be a real breakthrough in collapsible inflatable boat design.
Zodiac has had a collapsible RIB out for a few years now, the Ribster 530 LSC (Light Strike Craft). This has a sectional aluminum hull that can be taken apart and has been used by various marine forces. It's an interesting design but meant for pretty specialized applications since it weighs 345 kg and takes 3-4 people close to an hour to assemble it. Here is a link to it's specs;

Oh yeah - it sells for about 50,000 USD (hull only).
