IBike: iPhone Wrist-Mount for Motorbikers
Wrist-mounted control panels are a sci-fi staple, used to remote control anything from spacecraft to cars to time machines. And while the French iBike might not actually remote control anything, it certainly looks like a movie prop.
The system is modular, and at its most basic (and cheapest — around $40) is simply a waterproof, arm-mounted case for motorcycle riders. Spend a little more and you can add in an extra battery and a helmet-mounted mic and headphone for cellphone conversations (a terrible idea on a motorbike) or for listening to turn-by turn GPS instructions.
The full kit will cost just under $140, plus shipping (and it ships from France, so make sure you check those prices.) Bat-Tastic!
