Greg Dunham holds the Guinness world record for building the world’s largest motorcycle. The Monster Bike is 11 feet tall, 20 feet long and has a price tag of $300,000. Amazingly, Greg did it all by himself in his workshop at home.
On account of its huge dimensions, the bike can only be driven using a steering wheel. Unless I’m missing something here, that actually makes it a ‘Monster Truck’. I guess Guinness knows better.
