i think the idea should have been a sloution for transportation because not just cars cause carbondioxide. The bike idea is only a solution for the traffic inside of the city. And here we are searching for a universal solution, this bike idea is not possible for the whole world because the world is not covered with straight plane roads all over.. and also people in every age cannot ride bikes.
shortly this idea is not universal and not solving the main problem.
if you would offer a new type of transportatin for every type of climate, every type of people which people can use instead of cars and other vehicles, which also doesnt cause carbondioxide, this would be perfect.. but not your idea.
