没有欢乐的刹车(Without the brakes of joy)

两轮，没有燃料，有很多好处：自行车是一种无障碍、绿色和健康的交通工具。踏板可以改善身心健康，有助于减少污染和缓解交通拥堵。出于这个原因，联合国每年6月3日庆祝世界自行车日，以纪念这辆简单而强大的汽车。

Two wheels, no fuel and with many benefits: the bicycle is an affordable, ecological and healthy means of transport. Pedaling improves physical and mental health, helps reduce pollution and decongests traffic. That is why the UN celebrates World Bicycle Day every June 3, a tribute to this simple but powerful vehicle.
