Hammerhead LED-based bike navigation keeps you on the righteous paths
 

Developer Hammerhead Navigation thinks it has the solution to safer cycling: LEDs. It created a bike-mounted tool that does everything with its flashing diodes: turn-by-turn navigation, suggests crowd sourced-paths (via Strava and MapMyRide) and will even point you to the nearest Citibike exchange. The unit pairs with your iPhone or Android's GPS to help find invisible bike trails through your city, and supposedly it can function without a data connection -- perfect if you're a desert cyclist. A $75 pledge ($70 if you act fast) will get you one gizmo, or a $140 promise will get you two. You like to spoil your riding buddy now and again, don't you?
