Intelligent mayors are introducing bicycle-sharing systems to improve the use of this ecological way of transport all around the world. Allowing citizens to use them at cheap cost increases the number of bikers on streets who adopt better habits in turn. As a result, cities and villages are benefiting from it as the air inhabitants breath is more convenient from a health perspective and the noise is reduced.

Although bike-share began in Europe in 1965, it was not until the 2000s that a viable format appeared thanks to information technology. Nowadays the public systems include technological advantages about which I will talk in the future. The bikes in the bike-share services varied as bicycles themselves do. There are normal and electrical bicycles, those which works with a card or a mobile app, with solid wheels or full of compressed air, etc. All these differences have impacts on the service. For example, the solid wheels minimize their maintenance since they do not poke, but it is easier to have an accident when raining.

One key element is the anchor system. If two pieces form the anchor, it is more complicated to put the bike on the station. On the other hand, if it only has one, metallic piece the action is facilitated. The bicycles weight is also another point to have in mind. Too heavier bikes discourage people to use them, whereas light ones are better specially if they move on a hilly city. Interconnection is also important mostly when close cities and villages have their own bike-sharing services. There is nothing more inconvenient that the obligation of changing the bike, and hence having for instance two bike cards, the moment you pass from one location to another.

To sum up, bike-sharing is a good way to improve the number of bikes, but before launching it, some issues should be taken into account.
