I'm still trying to understand why you want an electrical duct on a bicycle, let alone why you would put a fan in it.

The duct improves the efficiency of the fan, I suspect the whole assembly is required as the rider is not eating enough beans and needs some further wind assistance.
But, since efficiency is lower with high velocity flow than low velocity flow, wouldn't it be better to have a nice little epicyclic gearbox and a _BIG_ propeller?

Well if it's efficiency that's important, why doesn't the fellow fit a couple of sprockets linked by a chain that he can turn with his feet? Can't get more fuel efficient than that.
