Public bicycles are shared bikes available for short-term use, often found in urban areas. They are part of a bike-sharing system, allowing users to rent a bicycle from designated stations and return it to any other station within the network. This service promotes eco-friendly transportation and helps reduce traffic congestion. These systems typically operate through a mobile app or membership card, making it easy for users to access bikes. Public bicycles are usually designed for casual riding, with features like adjustable seats and sturdy frames. Cities like Paris and New York have successfully implemented such programs to encourage cycling.
