How much faster could this vehicle go downwind compared to the speed of the wind? Is there some sort of theoretical limit?

so I'm thinking the magic is in the reduction gearing
it's not the prop pushing the thing forward, it's the wheels, the prop just steals some energy from the wind
electric drive would probably be safer btw, I don't like those long bike chains
or at least do a driveshaft

Depends on prop geometry. Anyone saying anything else is retarded
