Perhaps your calculations are off ? You would probably need to have the items in hand to do a proper calculation; just sayin'...
Actual ratios are dependant on a number of factors, including actual tire size, belt length and deflection. Basic ratios are 19:1 to 24.5:1 - the #12 gear offers ratio of 22.25:1
Your assumption is incorrect - 296 teeth wouldn't be the accurate count-IF teeth were all the way around the drive ring; two spaces w/o teeth is not same distance as portion with teeth.
No one has posted an answer to the original question:
"How many teeth are on the motor and wheel pulleys?"
GEBE does not state on their site how many teeth the drive ring has - only the number of teeth of the various pinion options.
Regarding the drive ring they only make the cryptic statement "...less resistance allows for 148 teeth in the belt track..." but they do not state how many teeth there are on the drive ring.
Crunching the numbers, there just have to be more than 148 teeth on the drive ring.
From the information that mppardee posted above, from a response from Julia at GEBE stating:
"the #12 gear offers ratio of 22.25:1"
(Despite this number having four significant digits, it can't be all that accurate. This would work out with the drive ring having 265 1/2 teeth, which isn't physically possible.)
So....
Is there anyone out there who knows this number for certain (or who has a GEBE kit and would be willing to count number of teeth that there are on the drive ring)?
A BIG "thanks in advance"!

Edit:
A thought just occured to me...
Are there ANY TEETH AT ALL on the drive ring itself???
If not, can anyone confirm this for me?
Another "thanks in advance"!
