Imagine a solar bike for the Sun trip Tour 2017!

How do I go about making my solar bike? I don't own an electric bike, I don't know much about solar energy capture… So the questions are in all directions:

  • For electric bike: What type of engine? Motor hub or pedal?  Motor on the bike or on the wheel of a trailer that pushes the bike?
  • What power for the battery?
  • How can the power of the sun, irregular, charge the battery? How does it regulate?
  • For solar panels: how much? What power? What size? Where to install them? On the bike, on a trailer, on both? How to fix them?

To sort out all these ideas, I realize a mental map: I'm looking for resources on the Internet, there's no shortage. Of course I fall on "the" precursor: from France to Japan by solar bike
