The German electronics company Conrad sponsored a challenge titled: “3 teams, 14 days, 150,000 possibilities”. Their “team A” from Hamburg came up with this bicycle lock that hoists your bike up a light pole, keeping it out of reach from thieving hands. If you’re interested in making your own version, you’ll need to translate from German, but you can find a list here to reproduce the lock yourself, and can even purchase the parts from their website.
