Because bad ideas come in all shapes and sizes, this is a video of Youtuber Gregulations constructing a motorcycle version of a penny farthing using a Yamaha YZF-R6 and a bunch of custom built parts. Despite having training wheels, the resulting cycle has deathtrap written all over it, and at 14:40 Greg does about 4X the speed anybody should on that thing. Who knows, maybe that top hat doubles as an airbag. My point is this: Greg really should have grown a handlebar mustache for the video.
