When it comes to mounting your iPhone 4 on a bike, we know it’s hard to trust anything. This is where Biologic comes in and creates a case that protects your iPhone against knocks, scratches, weather, sweat, and mud. A touch-sensitive cover membrane on the front of the case still allow full control of the iPhone’s screen. This Biologic Bike Mount ($65) is the first serious bike mount compatible with the iPhone 4. It pivots so you can use your iPhone in portrait (as shown) or landscape mode (perfect for GPS apps for example).
