If you tend to get around town on just two wheels and a whole lot of pedal power, chances are you hang out with a similar group of friends as well who don’t mind sweating it out a bit just to do their bit for the environment when traveling. Well, there might be some of you out there who have experienced the pain of losing a bicycle to a thief, and perhaps the Halo bicycle lock concept could prevent such untoward incidents in the future. It comes with an Eye-Fi card that will allow it to send an alert to your smartphone wirelessly the moment your lock is tampered with – of course, this means you must always park within a free Wi-Fi zone for this to happen.
