While most cities are keen to promote bike use, few foresaw the problems caused by dockless bike-sharing schemes such as oBike and Reddy Go. The advantage of dockless bikes is that users needn’t find dedicated stations to pick up and return the bikes. Instead, the user leaves the bike in a public place for the next rider to use. But the disadvantage turns out to be that these bikes are littering streets or being dumped in parks and rivers in cities in Australia and overseas.
