For urban dwellers, bike racks have become vital in promoting bicycle use in congested city areas. Many cities worldwide are now embracing the concept of bike-sharing systems, which allow users to rent bicycles for short periods. Effective bike racks are fundamental to the success of these programs. By providing secure parking spaces, these racks reduce the fear of theft and damage, which can deter individuals from using bikes as a primary mode of transport.
