Cue the bike dispensing machine. Brought to you courtesy of bikedispenser.com, a small firm from Amsterdam, the idea is to help facilitate bike rentals in urban areas. Cyclists pay a small fee to hire a bike, and then they can take it where they please. Once they’ve finished, they can return it either to that machine, or another one across town. And because they’ve been fitted with RFID tags, they won’t all have been nicked before you can get one.
