Japan has built underground bike vaults, to enable cyclists to safely store and park their bicycles without taking up pathway space. With this parking design, cyclists do not have to worry about their bikes being stolen or exposed to bad weather. The parking vault is even designed to withstand earthquake tremors. Another upside of the invention is that it frees upspace in the cities where space is limited. In Tokyo, 78% of households own a bike. Getting all those bikes away from pathways when parked would save a lot of space. In the vaults, bike share fitted with a locator device that correspond to a personal card that the user swipes to check in and out, and it only takes eight seconds to park. To date, there are 50 of these vaults across Japan, and global expansion in Japanese cities is envisioned.
