Ofo is a bike-sharing platform that originated in China in 2014. It allows users to rent bicycles through a mobile app, making it easy to access bikes for short trips. Users can locate, unlock, and pay for the bikes using their smartphones, promoting convenient and eco-friendly transportation. The service gained popularity in various cities worldwide, contributing to the growth of the sharing economy. Ofo's bright yellow bikes became a common sight in urban areas, encouraging people to choose cycling over driving. However, the company faced challenges, including competition and operational issues, leading to its decline in some markets.
