It's a simple concept: the TiGr is a titanium bow that is secured with a pick-resistant cylinder to form a closed loop around the wheels and lower part of the frame (and, of course, a stationary object). The long, slim form factor allows the rider to secure both wheels—without having to remove them—and lends itself to a unique method of storage: it doubles as an ad hoc top-tube protector when not in use.
I met Joshua A.C. Newman on Velospace.org when I went there to discuss the viability of TiGr. That's him behind the camera in the video, and that's his Cannondale. We hit it off immediately and we started working together to bring this design to reality. He's used half a dozen prototypes ever since, from the very earliest to the ones you see here. He brings his design expertise to the challenges of the lock, sending sketches back and forth about usability, practicality, and aesthetics, from the color of the coating to way to store the lock when it's not in use. He's making sure the lock is about the same efficient beauty as the rest of the bicycle it integrates with.
