Diff ratio = DI / (FS x 1/2)
DR = 20 / ( 12 x 0.5 )
= 20 / 6
= 3.333

To confirm the differential ratio, lock one side of the diff so does not turn, turn the diff input (DI) a certain number of time while you have the other person count the number of times the free side (FS) turns. Then divide the number of turns the hub has done by two and divide into the number of input turns. The divide by 2 is because the diff is stopped from turning on one side and this makes the free side rotate at twice the normal speed. Diff ratio = DI / (FS x 1/2) DR = 20 / ( 12 x 0.5 ) = 20 / 6 = 3.333
