Hi guys,
So I'm building a small electric skateboard, and I'm having trouble understanding how much power I need to keep the board in motion. The total weight of the board is 30Lb and I am about 170Lb. I want to maintain a speed of 15Mph when not kicking my leg. This is to be assumed on a 1 degree incline. I have two motors that are 300 watts each and have a free speed of 18700rpm on a 12v 30A circuit. The torque before gearing is .71 Nm. I am hoping to do a 16:1 gear reduction connected to wheels 80-110mm. What size wheel will work best, and will this gearing be enough?
