Creative bike locking has been a topic on Bike Hacks before. I'm sure that Bike Snob NYC has coined a term for hipsters that lock their bikes high on poles like this one I captured a while back . If you know the slang, or have a term of your own, feel free to share in comments.
This lock job, and at least in my view, the poorly designed NYC bike racks led me to propose my own bike rack (seen below) in a previous entry.
Thanks to reader Clifford, I am now aware of some engineers who have taken locking your bike to a whole new level - literally. The video is probably much enhanced if you understand German, but lack of fluency in German will not hinder your understanding of what is going on too badly. If you want to skip straight to the heart of things (and don't understand German) start at the 1:20 mark.
Do you lock you bike in a creative fashion? Feel free to send your hack to us for posting.
