Unorthodox ideas like this one by Brit Kevin Scott are often the germ for more advanced designs, but I think this one takes things a bit too far. A built-in lock utilizing the bike itself is a great idea, but messing with a key structural element like the frame bars is a dangerous move. Although the mechanism here is cool and convenient, I wouldn’t trust it (or the bike) after a few months of rattling along cracked streets and catching the occasional raindrop.
This guy’s clearly got a good noggin, though. Keep up the good work, chum.
