I need a motorized bike, any reccomendations?

I need to be able to travel up to 55 miles one way every day for work for up to 2 months. In the wintertime if that makes a difference. Im having trouble deciding if i should get an electric bike, a gas powered bike, or a moped until i get my license in hopefully 2 months. I weigh about 220lbs. 5'8" if that matters. I need it to be 50cc or not much more since i dont have a license
