OK, this is just awesome. This guy Nils Ferber built a...a...well, I'm not sure what to call it, but it's a vehicle that's powered by a couple of 18-volt cordless drills. (If your first question is "why," then, sadly, this blog isn't for you.) The Drillcycle reportedly has a top speed of almost 20 mph. Click on each photo to see a larger version:
More details on this project are found here, and a description of the design and fabrication process is here.
Given the rider's position, a full-face helmet is certainly justified; one can generate a serious case of road rash even at 15 mph.
I wonder what Nils could do with a chainsaw?
