The Angle Lock Twists Your Front Tire to Prevent it From Riding Straight

 - Jan 11, 2014
The Angle Lock has been designed to make swift bicycle theft difficult. The system makes it appear as though your two-wheeler has been left unbound; however, this proposal is for a built-in system that fixes your conveyance in an awkward position.

Tsung Chih-Hsien and Liu Li-Hsiang suggest embedding a combination lock into the frame of the pushbike, and one that latches shut only when your front wheel is turned to a 30-degree angle. With this fixed arrangement, a potential thief cannot simply jump on and ride away with your bicycle. The Angle Lock bike lock makes it hard for anyone to drag it too, and it cannot be reoriented for storage in the back of a car -- not without breaking the frame.
