My daughter is going to college in the fall, and that means we’re making lists of things she’ll need to take with her. She’s thinking about taking a bike for the trek from the freshman dorms to her classes, and that means she’ll need a bike lock. A lock like the Skylock would make her life easier, because she wouldn’t need to fiddle with keys to lock and unlock her bike. The Skylock connects to a smartphone with Bluetooth, so you can lock and unlock the Skylock with an app. Skylock can also sense your proximity to the bike and unlock as you approach, and it will automatically lock as you walk away. It’s powered by a solar-charged battery; one hour of normal sunlight charges the battery for about a week of use (5 lock/unlock events a day and 2-3 hours of WiFi connectivity). If you are in an area with free WiFi connectivity, the app can notify you if someone is tinkering with your lock. And if your phone is dead, you can unlock the Skylock by keying in your code on its capacitive touch screen. Skylock will ship in early 2015, but you can pre-order now. The normal price is $249, but you can pre-order for $159 for a limited time.
