Beijing has long been well known for the number of bicycles on its streets. Although the rise of motor traffic has created a great deal of congestion and bicycle use has declined, bicycles are still an important form of local transportation. Many cyclists can be seen on most roads in the city, and most of the main roads have dedicated bicycle lanes. Beijing is relatively flat, which makes cycling convenient. The rise of electric bicycles and electric scooters, which have similar speeds and use the same cycle lanes, may have brought about a revival in bicycle-speed two-wheeled transport. It is possible to cycle to most parts of the city. Because of the growing traffic congestion, the authorities have indicated more than once that they wish to encourage cycling, but it is not clear whether there is sufficient will to translate that into action on a significant scale. On 30 March 2019, a 6.5 km (4 mile) bicycle-dedicated lane was opened, easing the traffic congestion between Huilongguan and Shangdi where there are many high-tech companies. Cycling has seen a resurgence in popularity spurred by the emergence of a large number of dockless app based bikeshares such as Mobike, Bluegogo and Ofo since 2016.
