The island is 18 kilometres (11 mi) long (north-south), and 8 kilometres (5.0 mi) at its widest point. It has a population of approximately 55,000, mainly concentrated in the two villages Muang Saen (west) and Muang Khong (east); the latter is the de facto capital of the island as well as the regional seat of government. The former President of Laos, Khamtai Siphandon has a residence on the island, which is a possible explanation for the high-quality of infrastructure, such as asphalted roads and electricity, on Khong Island. Locals tend to travel on longtail boats.
Khong Island is noted for its natural beauty and is a growing tourist destination. Many tourists combine their visit to the island with a visit to nearby Don Det and Don Khon islands, where it is possible to view the Khone Phapheng Falls.
Bicycles were introduced in the 19th century in Europe and now number more than a billion worldwide, twice as many as automobiles. They are the principal means of transportation in many regions. They also provide a popular form of recreation, and have been adapted for such uses as children's toys, general fitness, military and police applications, courier services and bicycle racing.
The basic shape and configuration of a typical upright, or safety bicycle, has changed little since the first chain-driven model was developed around 1885. However, many details have been improved, especially since the advent of modern materials and computer-aided design. These have allowed for a proliferation of specialized designs for diverse types of cycling.
The invention of the bicycle has had an enormous effect on society, both in terms of culture and of advancing modern industrial methods. Several components that eventually played a key role in the development of the automobile were invented for the bicycle, including ball bearings, pneumatic tires, chain-driven sprockets, and tension-spoked wheels.
