the name came from Okada Airline , which used to fly between cities in Nigeria. It was not known for comfort, but it was popular. the planes usually got to places more or less on time.When the first motocycle taxis appeared in the last 1980s, some of the drivers started using that name.They liked to think they were flying over the roads.The airline stopped flying,but people continued to use the name fre the motorcycle taxis.Now there are many thousands of Okadas in Lagos,as well as in other nigerian cities
