"World Bicycle Day" is a holiday designated on June 3rd by unanimous resolution of the 72nd United Nations General Assembly on April 12, 2018.

The General Assembly considers sports as an important driver for sustainable development, contributing to the achievement of the Millennium Development Goals and the 2030 Agenda for Sustainable Development.

Efforts need to be strengthened and further coordinated at all levels, including multi-stakeholder partnerships, to maximize the potential of bicycles in promoting the realization of internationally agreed development goals, including sustainable development goals and the objectives of the 2030 Agenda for Peace and Culture.

Regular moderate-intensity physical activities such as cycling are beneficial to health. The benefits of physical activity outweigh the risks of accidents at all ages. Engaging in some physical activity regularly is better than none at all. Simply incorporating some relatively simple physical activities into the day can easily achieve the recommended activity levels.

The World Health Organization (WHO) states that safe walking and cycling infrastructure is also a means to promote health equity. For the poorest urban residents who cannot afford private cars, walking and cycling can reduce the risk of heart disease, stroke, certain cancers, diabetes, and even death, while providing them with a mode of transportation. Therefore, improving such active modes of transportation is not only healthy but also cost-effective.

Meeting the needs of pedestrians and cyclists is crucial for addressing transportation issues, helping cities decouple population growth from increased emissions, improving air quality, and enhancing road safety.

On March 15, 2022, the General Assembly passed a resolution to mainstream cycling into public transportation systems to promote sustainable development. The Assembly emphasized that bicycles are a sustainable mode of transportation, sending positive signals for promoting sustainable consumption and production and having a positive impact on climate.

So, what are the classifications of bicycles?

1. Road Bikes

Designed for use on smooth road surfaces, road bikes prioritize high speed. They often feature drop handlebars to reduce air resistance, narrow high-pressure tires for lower resistance, higher gears, and larger wheel diameters compared to typical mountain bikes.

Since the frames and components do not require the reinforcement necessary for mountain bikes, road bikes are often lightweight and efficient, making them aesthetically pleasing.

2. Cyclocross Bikes

Developed from road bikes, cyclocross bikes originated from riders seeking to conquer both roads and off-road trails. These bikes feature sturdy road frames and wheels, stronger brakes, wide tires, and mountain bike pedals.

Cyclocross bikes can achieve high speeds on roads while also possessing some off-road capability.

3. Track Bikes

Designed for use on indoor or outdoor velodromes, track bikes have a simple structure: single-speed, no brakes, and non-reversible flywheels. Slowing down requires reversing the pedal motion.

4. Mountain Bikes

Originating in 1977 in San Francisco, USA, mountain bikes are designed for riding in mountainous terrain. They typically feature gear shifters for varying levels of effort or speed, and some may have shock absorbers installed on the frame. Some tires have aggressive tread patterns for riding on unpaved surfaces.

Mountain bike components are generally sized in imperial units, with wheel sizes of 24/26/29 inches and tire sizes ranging from 1.0 to 2.5 inches. Frame sizes are also measured in inches, such as 14", 17", and 19", indicating the size of the frame.

In conclusion, the designation of "World Bicycle Day" underscores the pivotal role bicycles play in promoting sustainable development, health, and equity worldwide.

Whether it's navigating urban streets or traversing rugged terrains, bicycles offer not just a mode of transportation but a pathway to a healthier, more environmentally friendly future. As we celebrate this day, let's continue to support initiatives that enhance cycling infrastructure, prioritize active modes of transportation, and foster a global culture of cycling. Together, we can pedal towards a brighter and more sustainable tomorrow for generations to come.
