Vertical Parking

Short answer: Before the robot could fetch a bike in seconds, someone had to decide to bury the bike rack. Giken designed the ECO Cycle to end messy, illegal bike parking around busy train stations, under a simple idea: keep only a compact entrance booth on the sidewalk and put the parking underground.

The bikes sit in racks arranged around a round shaft, with a rotating elevator in the middle, and the shaft is built to withstand a quake of Japanese seismic intensity 6-upper. The first unit opened at Kochi University of Technology in June 1998.

Why would a city bury its bike racks?
