20 inch low rider

Depends on what your are using for an engine set up, but I just finished one with a G4 and am running a 34t rear with an 11t secondary driver. Top speed is around 35. Its geared a bit too high so am planning on dropping to a 9 or 10t driver. Am satisfied with the 34t rear, a 36 would probably work well too.

I dont run 2 strokes but I believe the primary reduction is about the same and the drive sprocket is 10T. Running that through the calc. a 10/34 final drive with a 20" tire @ 7000 rpm would be 30.6mph. I am running moped tires which are 21" overall so its a little faster at the same ratio and the reason Im a little over geared with the 11t driver. Kings has the 34T for $24 I believe on ebay now, may be cheaper on their site. See the sellers on the left of the forum page.
