Hey everyone, really neat that you know our bike lock even outside Germany, amazing :)
I want to add that there's no plan to sell this,it would be to insecure (and like you already mentioned, what would happen if someone parks under your bike?).
But you can build it, the components and construction manual are online (http://www.conrad.de/ce/de/content/ti_fahrradschloss/ti_fahrradschloss). Perhaps a expensive but unusual idea for christmas ;)

Greetings,
Tanja
