Keep your phone charged while on the road! This cheap DIY device clamps onto your bike, and harnesses the rotational energy from your wheel, transforming it into electricity that charges your phone. You can keep your phone on your handlebars for easy access to navigation apps while you ride! (GPS apps only though, no games or texting.) The files are easily editable in the chance that the parts don't fit your bike. Currently designed for the iPhone 5, this setup is easily adjustable to any phone, use this as a basis for your own version!
