Electric All Wheel Drive Fat Bike using the Grin All-Axle Hub Motor

A winter fat bike built as an all wheel drive electric-human hybrid, using the Grin All Axle Hub Motor. For more details on the build, check out the blog post at http://cycle9.com. BTW - the noise when I spin the wheel is from the tire knobs rubbing on the ground, NOT from the motor (the motor is silent).
