What freewheel would, coupled with a 52 tooth chainset, be equal to a 18-44 setup?

Question

My other singlespeed bicycle has an 18-44 gearing setup, and I want to have the same ratio on another bicycle that I am building. The chainset I have has fifty-two teeth, so what size freewheel should go with it to make an equal ratio?

Answer 1

ok gear ratios  divde number of teeth on large chainwheel by number of teeth on freewheel will give ratio of around 2.4:1 therefore the answer to your question would be 22 teeth to give same ratio

Answer 2

I keep coming up with 21

Answer 3

For future use, divide the chainring by the rear cog. 44/18=2.444.

This means 52/x=2.444 x=21.276. A 21 tooth rear will do great.

EDIT: I was thinking about this some more. Do you realize that the 44/18 setup will be easier to pedal, right? Going to a 52T chainring transfers the torque and will make it harder to pedal even with the same ratio.
