# Vertical Parking (DD-755)

> 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.

## Write-up

Part I: why Japan put its bike racks underground, and the round, quake-ready shaft that made it work.

1. **Just a booth on the sidewalk**: Above ground there's only a compact entrance booth. The parking is buried below it.
2. **200+ bikes underground**: Each unit stores 200 or more bicycles in racks arranged around a round shaft.
3. **A rotating elevator**: A robot in the middle spins as it moves, filing each bike into the racks around it.
4. **Tap a card**: Push a button to store your bike. Swipe an IC card or tag to call it back.
5. **Back in 13–15 seconds**: That's the average wait for your bike to come up, even at rush hour.
6. **Built to clear sidewalks**: It was designed to end messy, illegal bike parking around busy train stations.
7. **First unit: 1998**: The first ECO Cycle opened at Kochi University of Technology in June 1998.
8. **Earthquake-ready**: The shaft is built to withstand a quake of Japanese seismic intensity 6-upper.
