Interesting article in CW on raising your mileage and speed. Fit a second magnet to your wheel or feed a smaller wheel info into the computer. That would be cheating of course, is there anyway of callabrating or checking that the “speedo” is reading correctly? The only thing on my bike is a bell, a very nice FWE but alas it does not record my mileage, so a quick guess would be between Wayne’s and Dave’s. How many extra magnets would Wayne require to match Dave’s mileage?
