When summer rolls around, so do the bikes, which also brings out those thrifty thieves. But with the Halo bicycle lock, you won't have to fret about leaving your vulnerable bike alone on the hard streets of whatever city from which you hail. A wireless creation, it syncs to your smartphone to inform you when something suspicious is happening to your precious ride.
Designed by Steve Hunt, the Halo bicycle lock specifically uses "a Wi-Fi enabled SD card called an Eye-Fi that you'll find in digital cameras," according to Dvice.com. Therefore, the only real drawback is that your bike has to be locked in a Wi-Fi zone in order to work--that, and the fact that is simply a concept for now.
