If. A 10 tooth sprocket on the motor with a 36 tooth sprocket on the wheel gives. About 35 mph with a gerar ratio of .278 and a 50 tooth sprocket on the wheel gives more hill climbing with a gear ratio of .20 what ratio do you think would allow standing starts with no pedaling for ur avg chinese 2-cycle?
Gear ratios calculate like this:
Engine has 83t/20t = 4.15:1 internal gears
36t/10t = 3.6:1
3.6 X 4.15 = 14.94:1
50t/10t = 5:1
5 X 4.15 = 20.75:1
Just so you know.
