This Is the World's Fastest Penny-Farthing

The penny-farthing went out of fashion in the 1880s, despite the efforts of some modern people to revive the traditional bicycle. Perhaps Greg Mitchell's variant, pictured above, will re-establish it.

Motorcycle News reports that Mitchell is an engineer in Swindon, UK. His "Super-Farthing" is built with a Yamaha R6 sportbike. He machined 420 parts from scrap steel to convert the motorcycle into this high-rise vehicle.

Note the rear stabilizers. Initially, Mitchell built these to lift up and out of the way, but he found the bike too difficult to maneuver without them. So it's functionally a lifted quadricycle. Mitchell has taken it up to speeds of 50 MPH.
