So Mahin caught a mistake we had made in the calculation for the drive train gear ratio. Originally, we had assumed the size of the drive wheel would be as large as the original stock Segway wheel, but now that we are going with a much smaller snowmobile drive wheel, we actually need to gear UP slightly instead of down. The numbers might not be exact, but it should be about an 8:7 ratio, so the sprocket on the motor should be a little larger than that on the drive wheel. We could get the right ratio easily using 16t and 14t sprockets. Mahin will do some research on snowmobile drive trains since we have compatible drive shafts we can make good use of.
