Makes sense. But with some room for improvement. Here, you'll need at least a double bicycle front chainring. Maybe you'd want to add a second chain connected from the bigger front chainring to the rear wheel sprocket for added speed and extra momentum to faster spin the propeller, while keeping the longer chain connected from the smaller front chainring on to the propeller. The propeller now spun faster, will then add extra push to the previous overall bicycle speed, while at the same time make pedaling much easier than on the traditional bike setup.
Imagino que al contrario de lo que pueda parecer en vez de darte más velocidad te retrae ya que necesita la hélice de empuje de aire y eso te frena un poco la velocidad inicial de tu esfuerzo eso creo. I imagine that contrary to what it may seem, instead of giving you more speed, it retracts you since it needs the air-push propeller and that slows down the initial speed of your effort a bit, I think.
I like this. But with human power at cycling speeds the efficiency will be improved with larger propeller and more blades for increased area. Apart from that the efficiency would be even higher with true wingshaped blades, it's just to look at airplane propellers to see how it looks. And make this machine based on a racingbike!
For uphills a larger propeller is required. And this propeller actually is smaller than optimal even for flats taking in consider the human power and the weight and friction.
Não vi melhoria nenhuma. O que vi foi um utensílio capaz de causar acidentes, se passar em um local com grande quantidade de gente. Essa hélice não melhora o desempenho da bicicleta. Vai melhorar o desempenho físico de quem está pedalando, pois vai ficar mais pesada.
