Taxi calculator? (propeller type and speed, aircraft weight, taxi speed)

According to YouTube, a significant number of people have used propeller power for pushing a bicycle. I wonder if any of them have calculated their design, or if all of them have been simple experiments. That is probably what I will end up doing some day.
