The Bitlock makes your old, key-driven bike lock look like a museum piece. It connects to a smartphone app via Bluetooth, and when it detects that you're in close proximity, you can open the lock with a simple push of a physical button on the side of the shaft.
But the Bitlock app does way more than that. Suppose your bike is locked up in some random, remote location, and you want a friend to ride it back home for you. No problem: You can manage access directly from your phone. The app also maps your bike routes and gives you stats on how many miles you've ridden and how many calories you've burned. At press time, Bitlock needed less than $1000 to reach its $120,000 Kickstarter goal.
