[Pro-health cycle lane versus environmental pollution and trauma].

A bicycle as a mean of transport and recreation, but is it a healthy lifestyle? The construction of numerous cycle lanes in cities and promotion of physical activity aims to encourage the public to move around by bicycle. The aim of mass cycling is to reduce car exhaust emissions and, on the other hand, to improve public health. The paper presents the potential benefits of cycling, but also its negative effects on the human body. Minimizing the danger of using a bicycle lies not only with cyclists, but also with people who are planning to build cycle lane.
