Resumen
The fact that public transport, with particular regard to the urban logistics, experiences difficulties in numerous Polish cities indicate there is a need to refine a transport network using an alternative mean of transport which is a bicycle. It is necessary to limit usage of traditional means of transport in favour of solutions generating zero emission of exhaust fumes. One such solution is bike & ride + bicycle & bike system. It was introduced in Bydgoszcz and now the bicycle is a complementary element of urban logistics.
