Motorized Horizontal Death Trap
This bad boy has an 80cc motor and for added danger, you can ride it in a whole slew of different positions. Ride it like a luge, or a trike, or go ahead, lie on your stomach and put your face right next to the engine. The more reckless, the better.
"This is the final version 3 of the Motorized mechanic creeper, built from a Craftsman mechanics creeper, a Harbor Freight 2.5HP 80cc motor, and garage junk. It goes 30MPH, and it's the only one in the world. This was engineered and fabricated for under a $200.00 budget."
