When you hear the words "3D-printed electric motorcycle," what do you think of? Two wheels held together by a weird, curvy, alien-exoskeleton-looking thing? Congratulations, you win...well, not one of these motorcycles since they cost $56,560 apiece. You win the satisfaction of knowing that you were right. A limited run of 50 of the Light Rider, which, as the name suggests, is unusually light for a motorcycle, is being produced by German Airbus subsidiary APWorks.
