A conceptual bike tree for cities with both a lot of bikes and a lot of bike crooks. Amsterdam, I'm looking at you: there is something seriously out of whack when a city's entire bicycle economy is based upon buying your bike back from the same brown-toothed junkie two to three times a month with the same nonchalance as a transaction with your local green grocer.
The concept's somewhat solid: the tree reduces bike rack clutter and lifts your bicycle above the bolt cutters of roaming thieves. It's certainly an attractive way to store bikes. Security is a finger print scanner, which may be a design flaw: after all, those bolt cutters can just as easily be used against your waggling digits as your bike lock.
