What is this "Airlock"? It is a V-shaped frame made of hardened steel that is mounted in a wall using clever screw connections. On top of this is a cover with a bolt that locks the bike and connects it firmly to the wall, so to speak. The locking cylinder offers a high level of security and the bike's storage surface is designed so that even delicate frames are not scratched. The stylish, immobile lock - which is also a wall mount - is available in gray, white and red. According to the Hiplok makers, the "Airlock" also cuts a fine figure in the office or living room.

The "Airlock" from Hiplok has already been approved on Kickstarter, with the 70,000 pounds having been raised a few days before the crowdfunding deadline. Around 300 supporters were so impressed by the lock idea that they made the start-up financing possible.
