24 cruiser gear ratio

(1/2) > >>

motomagII:
got a 24 dirt bike and it has 12t rear cog whats the correct front for this to give me same as my 20 inch which is 38x14

HEYWOOD BMX:
26 or 27

THIRSTYKIRSTY:
i gott a 25 for a tenner

James Nada:
Roughly speaking here's the maths:

38/14 x 20" = 54.29

27/12 x 24" = 54


So 27 is nearest -  and would be ever so slightly spinnier - but not much.


**And get some pics up - I wanna see it? What year is it?

motomagII:
in restoing it for dude at work .he is donating it to local lad whos bike got pinched and cant afford anopther ride .
i am doing labour and powder coat on it and trying to source parts foc of cheap as chips kinda thing .
so ineed summat 27 /28 and this will be same is not fogetting its 24 inch bike not 20
it had 33 on before but it was beyond repair
