If you use your bike more than once a week, it’s safe to say you’re going to want a Skylock. This new intelligent U-lock is the most advanced we’ve seen, and it has more features than the first cell phones we ever carried. It starts with a Bluetooth 4.0 connection to your phone. This gives you the ability to remote unlock, proximity based Auto-Unlock, remotely monitor your bike (it will alert you if your bike is disturbed), and even send help in case of an accident. The next thing we worry about with these types of devices is always the battery, but Skylock has a built-in solar panel that gives you a week worth of battery from a single hour of sunlight. And yes, there are buttons on the lock for access… just in case. The only thing the military grade bike like won’t do is open your beer. We’re ok with that.
