There haven't been a lot of elegant ways to add navigation to your bike -- unless you have access to prototype bikes, you're probably stuck mounting a GPS unit or smartphone that might take your eyes off the road. That's where Boreal Bikes' crowdfunded smrtGRiPS project might just come in handy. These install-it-yourself handlebar ends pair with your smartphone to give you directions, whether or not you're on the bike. While you're riding, the grips will shake for imminent turns or traffic problems. They'll also help you find your wheels, and you'll even get separation alerts if you're traveling with another smrtGRiPS-touting cyclist.
