Counting the teeth. that gearbox has ratios of 2:1 and 3:1. with a CIM motor that gives you an approximate output speed of like 2500 rpm and 1500 rpm. that’s not getting much use for that gearbox's size and massively thick gears. and in an attempt to keep it small you removed the material of the plate that the motor needs to mount to. That is however some very impressive modeling with the pockets in the plates, the bearings and as far as I can tell from that render Nomenclatural correct Gears with some weight reduction. I remember myself modeling stuff like that back when just starting to use Cad and making it look super good. its just that i got so far into the aesthetic details of things that I skipped over doing the math in the bearing and meeting the requirements of my designs. Often a wheel speed to aim for is around 70RPM for a 6” wheel. In high gear, if you were to use that gearbox with a chain drive you would need a sprocket ratio of about 35:1 that may mean using a 12 tooth sprocket and a 420 tooth sprocket on your 6-inch wheel. seeing as how a 420T #35 sprocket would be around 50 inches in diameter. That won't work
