Isn't the 'Lock. Bicycle' brilliant? If you had one of these, you wouldn't need to carry around bulky cables and keys, for the clever two-wheeler integrates a security feature into its very form. It would not work for every type of bike rack or fence, but the invention would function particularly well if you chose to prop your conveyance against a lamppost or a sign.
You can't quite tell how the clasp operates when the frame is closed, but basically, the top tube detaches towards the handlebars and hinges up from beneath the seat. The generously large gap created enables you to wrap Jens Andersson's 'Lock. Bicycle' around thick columns and broad tree trunks. Bright blue rubber lines the interior to protect your pushbike from scuffs.
