That is true, and I totally agree that promoting and advocating to have a World Bicycle Day can change many lives in a positive way. It is true that many common place items are now being replaced by modern innovations, but I think bicycle also represents our culture. If we looking for the definition of culture, which is the language, beliefs, value, norms, behaviors, and even material objects that characterize a group and are passed from one generation to the next. Bicycle was a significant transportation in the past, and there is a huge connection between our society and bicycle from many perspectives, like economy, transportation. Today, people may not ride their bike to school or work, but we should not lose our valuable culture. As a life changing instrument, bicycle should be kept and passed to our next generation. As a result, we definitely need a world bicycle day!!
