Drill Powered Bike, No Seriously a Hand Drill Powered Bike

I am serious.  Someone made a drill powered bike.  Check out the video below.  It actually works pretty good and looks like a blast to ride.

At first it doesn't seem very practical, but depending on how far it can go on a single charge it my actually be a cheap mode of transportation for the urban environment.  Think about it.  Batteries for these drills are relatively cheap, easily exchangeable and charge quickly.  I don't think it is such a bad idea.  Let me know what you think.

Here is another video example.  I apologize for the music.
