"For the Grasp Lock, you are the key"

To hear Grasp Lock co-founder and engineer Samson Berhane tell it, the primary problem with the bike locks already on the market is the bodily contortion they necessitate.

"No more stretching to unlock your bike," Berhane says in a Kickstarter campaign video for his Canadian start-up's biometric bicycle lock locked and unlocked by fingerprint. "No more reaching over the frame to secure your bike."

(The Grasp Lock's hinged arms, see, allow it to slide easily around your bike and the rack, making lock-up a snap.)

I'm more concerned with security than ease of use, though, so I was impatient for the video to address this aspect of the Grasp Lock.

"Its hardened metal body can resist virtually any attack," explains mechanical engineer Jason Zeng as the camera pans across three team members unsuccessfully wielding a crowbar, a saw, and a pair of long-handled cutters.

Impressive, but am I ready for a bike lock that requires batteries??
