The KHS bike she rode was a dragster in its own right. The low-slung, chopper-style bicycle is more than seven feet long and outfitted with 17-inch motorbike wheels for stability at insane speeds. It also demands a two-wheel drivetrain to propel the absurdly tall gear.
“The drive ratio is 62:12, twice,” said John Howard, Mueller-Korenek’s coach, who once held the motor-paced record himself at 152 mph back in 1985. “That’s roughly 488 inches, or approximately 128 feet per revolution. She’s traveling nearly 130 feet every time she turns those cranks. It’s pretty mind-boggling.”
It's pretty crazy. 128 ft per revolution!!!!
