“A monowheel is a one-wheeled single-track vehicle similar to a unicycle. However, instead of sitting above the wheel, the rider sits either within it or next to it. The wheel is a ring, usually driven by smaller wheels pressing against its inner rim. Most are single-passenger vehicles, though multi-passenger models have been built.

Pedal-powered monowheels were built in the late 19th century; most built in the 20th century have been motorized. Some modern builders refer to these vehicles as monocycles, though that term is also sometimes used to describe motorized unicycles. Today, monowheels are generally built and used for fun and entertainment purposes, though from the 1860s through to the 1930s, they were proposed for use as serious transportation”. – Wikipedia

A group of prospective police recruits, ready to be enrolled in the M23 controlled force, salute in the courtyard of a police station in Goma on February 6, 2025. More than a week after the battle for the North Kivu provincial capital, the M23 on Wednesday appointed people to public positions. Goma now has two officials for many public posts – two mayors, two governors – which locals said has created confusion. The M23 administration is still in its embryonic stages and struggling to respond to daily problems in the war-wounded city. (Photo by Michel Lunanga/AFP Photo)
