This may be helpful. According to the video the 5G reduction is around 6.83:1. Using the 10:44 gives you a total reduction around 30:1. Depending on your son's weight, the weight of the build, the engine size and the hill grade you may need as much as a 55:1 reduction to get up the hill. I live in Tennessee where there's a 50cc limit and an automatic transmission clause. Small engines, large people and steep hills means you must have gears. My way of getting around the automatic transmission clause was to build a bike that shifts engine gears automatically.
