Tilo Niebel and his gents at the Harzer Bike company in Germany, upon finding they had a tank engine to play with, decided that of all the more reasonable things they could build, they should construct a giant WWII German motorbike with sidecar.

The engine comes from a Soviet T-55 tank, which was a diesel V12 with 620 HP. The bike is almost 19 feet (5,8 meters) long, over 9 feet (2,75 meters) wide, and weighs 9,480 pounds (4,740 Kg).
