Do you bike today? Do YouBike rides kindle your passion to zip past one bicycle lane after another? Launched in 2009, YouBike's rental system offers cyclists an easy way to rent and return bikes. Cyclists only need an EasyCard to rent a YouBike. What's more, by using this system, bikes can be rented at one location and dropped off at another on a 24/7 basis. In Taipei City alone, there are as many as four hundred YouBike stations. This carbon-free vehicle rental system also extends to many other major cities. No wonder YouBike is acknowledged to have become part of the city landscape in Taiwan. Another important contributing factor in the growing popularity of this rental system has to do with its excellent cost-performance ratio. Each thirty minutes costs only ten NT dollars within the initial four hours. YouBike also serves as a best alternative to cars and buses during rush hours, when the traffic jam can leave you cranky. Perhaps one of its greatest contributions lies in the reduction of carbon emissions. In 2013, statistics showed that YouBike's rental service contributed to a trip distance of about 11 million kilometers. On this basis, the overall carbon emission reduction in Taipei City was equivalent to 6.89 million metric tons of carbon emissions from motorcycles and 27 million metric tons from automobiles. The success of YouBike also has a lot to do with its creative concepts. It boasts a database management system that can analyze the utilization rate of bikes speedily, resulting in efficient allocation of bikes among rental stations and ensuring that cyclists can rent a bike within ten minutes. With the goals of green economy and sustainable development in mind, it is time to go even greener. Let's all go YouBiking today!
