A Chinese bicycle-sharing start-up has formally announced that it plans to expand its business into Japan. Beijing Mobike Technology has enjoyed incredible success since its inception - and its disclosure that it has set-up a subsidiary in the Japanese city of Fukuoka has cemented its status as one of the fastest-growing start-up companies in the world.

The Japanese city of Fukuoka is set to deploy autonomous pods that will transport its passengers across the Hakozaki area, for free, towards the end of next year.
