I wrote a few months ago that vehicles are getting more and more efficient as efforts are being made in the USA, China and Europe. In the conclusion I was noting that it was good news but that more had to be done in biking among others.
It seems to be the case as Courrier International shown last July. Around the world, from Buenos Aires to Hangzhou and from New York to Moscow or Copenhagen, more and more people are biking.
This is good news as bikes are a great solution to many problems that are plaguing our communities : obesity, traffic congestion, energy use and air pollution.
