Another newb question here.
I was riding just a few minutes ago and when I got home it said I did 11.69 miles in 30:36, with a top speed of 47mph. I did take the downward side of a big hill as fast as I could and then kept up with a semi half way though town. I took the whole ride at a pretty solid clip, but I find it hard to believe that after my first week of street riding (and my first week in 20 years without a cigarette) that I could pull that off.
Sooooooo… How do you calibrate the little speedometer/odometer/timer/thingy-majig to make it accurate???
