A very strong 45-year-old Denise Mueller-Korenek recently rode a bicycle with 17" wheels for 5 miles on a the Bonneville Salt Flats, achieving a maximum speed of 183.93 MPH. That speed is 17 MPH faster than anyone ever went on a bicycle. (A spill at that speed can break more than 25 bones...)
For the first 2 miles she was towed by an automobile, accelerating to about 100 MPH. Only then was it possible for her legs to turn the cranks. Her bike was geared so that one revolution of the cranks would propel her forward for 128 feet.
She then was untethered from the automobile and gave 'er Snus accelerating by pedal power to about 184 MPH.
