Is 11nm of torque enough for an electric skateboard?

Hello, I’m interested in building an electric skateboard. I have used a calculator to determine the specs of the board with the parts I will be using. I am using a 6368 motor with 90mm wheels. The motor pulley has 16 teeth and the wheel pulley has 50 teeth. The calculator says that I could have a theoretical max torque of around 11nm. Is this enough for a 135lb rider to climb small to medium grade hills? Thanks in advance.
