Gear inches calculates how big of a wheel (in diameter) you'd have to have with no gearing to get the same ride as your bike. Think of the wheel attached to the cranks on a high wheel bike. The gear inches calculation uses the diameter of the theoretical wheel where your test is measuring the circumference of that wheel. Easy conversion, just divide your number by pi (3.14) and you'll have your gear inches for your bike as it's geared (circumference / pi = diameter).OK, I'm doing something wrong.
Right pedal- straight up,
mark the start of tire touching ground,
Pedal crank one full revolution until right pedal straight up again. 214 inches
I did the same with Velvet (same gear and tire size) 216 inches
I don't know.
