Check out this awesome new bike lock, Skylock, being created by Velo Labs. It alerts owners to possible thefts, emergency responders to possible crashes, and has a keyless entry for you and any of your bike-sharers. This lock has a solar powered battery (one hour of sunlight gives you enough charge for a week) that works with a smartphone app to lock and unlock your bike for yourself or for others to use. It can also send you alerts if your bike is roughly abused (as someone trying to steal it or strip it) using Bluetooth or Wi-Fi. Pre-order now for $159.00, or buy later when it retails for $249. Watch this video on how it works:
The Skylock will start shipping in early 2015.
