We really like this Kickstarter project put out by Helios (A startup made up of UC Merced alums). These are “smart handlebars” that can be put on your bike and offer a range of features. The lights on each side can act as turning signals along with providing visibility to motorists. One of the features that really stands out is the integrated Bluetooth and GPS. So if your bike is stolen you can track the location on your smart phone and provide that info to police.
