Treehugger really likes those ‘lectric bikes. We had that awesome-looking GPR-S the other day, but these are a little less… well, production. There’s DIY, there’s concept, and there is of course the spine-snappingly quick Killacycle (cool video there, wait till 1:15).

Even though they’re not buyable right now, these things are where innovation comes from, and these home-fried engineers are the talent that will be building the electric vehicle revolution of the next decade. Check out their creations here.
