On the occasion of the seventh World Bicycle Day established by the United Nations, several countries have organized green rides and environmental tours to encourage people to use bicycles to travel and reduce environmental pollution while strengthening their bodies.

According to incomplete statistics, the popularisation of cycling in a city of one million people can reduce carbon emissions by 7,600 tonnes per year. Encouraging cycling has become an initiative to protect the environment and help achieve the goal of carbon neutrality.

In some countries, governments, businesses, and the public are working hand in hand to improve infrastructures such as cycling lanes and parking networks, as well as installing canopies and publishing 'cycling barometers' to improve cycling comfort.

In addition to buying your bike, there are many shared bikes available for people to rent at any time without having to worry about the various problems that come with owning a bike, as well as keeping unused resources flowing.

Cycling is a way of saving, and not only is it a great way to get fit and healthy. The most important thing is that cycling is a green way to travel, as it does not consume fuel or electricity, it is green.

Nowadays, motor vehicles are very common and traffic jams often occur during peak commuting periods. Bicycles are flexible and can pass through narrow gaps with ease.

Shared bikes are easy to use, with all the processes such as deposits, top-ups, and refunds easily completed using the app. It's easy to find or reserve a bike because it's not a public bike with fixed pegs.

The average cost of a single use of a shared bicycle is low and there are often various special offers available, enabling the average user to have good cost expectations. With all these advantages, bicycle sharing has become an effective means of relieving traffic congestion in cities and solving the problem of "last mile" travel.

But there are two sides to every story, along with the practical convenience of bicycle sharing, there are also many problems.

1. The bikes are parked indiscriminately and used chaotically. In addition to indiscriminate parking, many users hide their bicycles in their homes or office buildings for their personal use.

2. Bad weather can affect cycling. Unlike taxis, the use of shared bicycles can be more affected by seasonal changes, weather conditions, etc.

3. It is not widely accessible and is mostly used by young people. Bicycle sharing is a new thing derived from the "Internet and transport", and even though it is not difficult to use, it is not an easy task for the elderly.

The best way to do this would be to increase the number of public bicycle outlets through the commercialization of enterprises and to solve the problem of indiscriminate parking through the supervision and construction of public facilities by the relevant authorities.
