Different combinations of 9 or 10-tooth driving sprocket with 31, 34, 38, 41, or 45-tooth driven sprocket gave ten possible ratios from 3.1:1 to 5:1.
Lower ratios for runabout to be run on smooth, level roads to higher ratios for loaded delivery cars to be run on rough, hilly roads.
Instructions for changing sprockets were furnished to owners, but the change involved disassembly of the transmission and rear axle -- definitely not a "quick-change" set-up
