This is not experimental. It has actually been done. Results verified with GPS.
If your wheel setting is 2200mm (on a 27.5" rim), multiply that times 0.62. That will give you 1364mm. Change your wheel size from 2200-ish to 1364-ish.
So, when your wheels are spinning super fast, the computer will say, "Well, duh. He's spinning teensy wheels. Party-on, Garth."
Change your display to read Km/hr and you will have a representative read-out for MPH.
Cool. thanks.
