In the past few months, we have covered plenty of smart helmets here. Not ready to upgrade yours? You can use Ahead to turn any helmet smart. It snaps onto your helmet and connects to your smartphone to bring you music, turn-by-turn directions, and ability to take phone calls / talk to Siri.
Ahead keeps your ears open, so you can stay alert while you ride your bike. Its brackets let you move Ahead from one helmet to another conveniently. Ahead is lightweight and water resistant. Expected to ship in October.[where to get it]
